Episode 22 – The Pros of LFTRs. Why They Are So Cool – Unintended Consequences – Chapter 8 Part 6

Russia Considering Thorium for Waste Burning

Advantages of LFTRs

Many of these also apply to MSRs that use Uranium)

  • No CO2 emissions.
  • Produce only a small amount of low radioactivity waste that is benign in 350 years.
  • The liquid fuel, besides being at 700-1000 degrees C, contains isotopes fatal to saboteurs.
  • Do not require water cooling, so hydrogen and steam explosions are eliminated.
  • Don’t need periodic refuelling shutdowns because the fuel is supplied as needed and the by-products are constantly removed. (LWRs are shut down every 2-3 years to replace about ¼ of the fuel rods, but, LFTRs can run much longer.)
  • Thorium 232 is far more abundant than U-235. Well suited to areas where water is scarce.
  • Do not need huge containment domes because they operate at atmospheric pressure. Breed their own fuel.
  • Can’t “melt down” because the fuel/coolant is already liquid, and the reactor can handle high temperatures.
  • Fluoride salts are less dangerous than the super-heated water used by conventional reactors, and they could replace the world’s coal-powered plants by 2050.
  • Are suitable for modular factory production, truck transport and on-site assembly.
  • Create the Plutonium-238 that powers NASA’s deep space exploration vehicles.
  • Are intrinsically safe: Overheating expands the fuel/salt, decreasing its density, which lowers the fission rate.

Also at play is Doppler Broadening

Fighting Doppler Broadening a.k.a the Doppler Effect
  • If there is a loss of electric power, the molten salt fuel quickly melts a freeze plug, automatically draining the fuel into a tank, where it cools and solidifies.
  • Highly efficient. At least 99% of a LFTR’s Thorium is consumed, compared to about 4% of the uranium in LWRs.
  • Are highly scalable – 10 megaWatt to 2,000 MW plants. A 200 MW LFTR could be transported on a few semi-trailer trucks.

  • Although our current LWRs are very safe and highly efficient, LFTRS are even more productive, and they cannot melt down.
  • Data from the Australian Nuclear Society and Technological Organization of the Australian government:
    + Thorium fuelled molten salt reactors have an energy return ratio of 2,000 to 1. [Also called Energy Density]
    + Our current LWRs that are fuelled with uranium have an energy return ratio of 75 to 1.
    + Coal and gas have an energy return ratio of about 30 to 1. Wind has an energy return ratio of 4 to 1.
    + Solar has an energy return ratio of 1.6 to 1.

Episode 21 – Proliferation? Not on Our Watch – Unintended Consequences – Chapter 8 Part 5

Nuclear Explosion

Taking the Easiest Course of Action

It would be very difficult to make a weapon from LFTR fuels because the gamma rays emitted by the U-232 in the fuel would harm technicians and damage the bomb’s electronics.

Uranium could be stolen during enriching, production of pellets, delivery to the reactor, and for long-term storage, but LFTRs only use external uranium to start the reaction, after which time uranium is produced within the reactor from thorium.

The Most Radioactive Places on Earth

The United Kingdom tried unsuccessfully over a period of 10 years, from the 1950’s to the 1960’s, to produce a weapon from Thorium. They gave up and switched to the uranium path. Still today, 1.5 tonnes of Thorium remain stored from that program. This is enough to power the entire UK for 10 years – Carbon Free.

The USA fired one Thorium driven test in 1955 (MET/Operation Teapot), but the results so poor and complications so high they did no further.

A 1 GW LWR [Light Water Reactor] requires about 1.2 tons of uranium per year, but a 1 GW LFTR only needs a one-time “kick-start” of 500 pounds [225 kg] of U-235 plus 1 ton of Thorium per year during its 60 year lifespan.

The half-life of Thorium 232 is 14 billion years, so it is not hazardous due to its extremely slow decay.

The primary physical advantage of Thorium fuel is that it uniquely makes possible a breeder reactor that runs with slow neutrons, otherwise known as a thermal breeder reactor. These reactors are often considered simpler than the more traditional fast-neutron breeders.

IAEA 2005

[When Thorium 232 takes up a neutron, the subsequent decay takes two paths: mostly U233 and some U232. The U233 provides most of the useful energy production by Fission. U232 provides protection against proliferation as several decay daughters are high energy gamma emitters – meaning they burn out silicon chips. For example the gamma spike coming from Thallium 208 is 2.6 MeV. ]

[Shielding using advanced materials and methods, such as distance (air), lead, and water can reduce radiation energy to levels where dosages are at recommended levels around 10 microSiverts per hour or 100 milliSiverts per year.

Note that there have been many examples of doses much higher than this causing no concern, such as 350 microSiverts per hour received by Albert Stevens for over 20 years.

Radiation shielding is a mass of absorbing material placed between yourself and the source of radiation in order to reduce the radiation to a level that is safer for humans.

This is measured by using a concept called the halving thickness – the thickness of a material required to halve the energy of the radiation passing through it.

Remember also, that Radiation decreases with distance in accordance with the inverse square law.]

Quotes by Albert Einstein

“I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.”

“Had I known that the Germans would not succeed in producing an atomic bomb, I never would have lifted a finger,” 

“I made one great mistake in my life-when I signed the letter to President Roosevelt recommending that atom bombs be made but there was some justification-the danger that the Germans would make them.”

“The release of atomic power has changed everything except our way of thinking … the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker.” – Albert said this in 1945, after the US bombed Japan with nuclear weapons and killed over 200,000 innocent civilians. Approximately 50,000 of them where children, 100,000 where women, and the balance the elderly. There were minor military casualties.

“Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage — to move in the opposite direction.”

“Peace cannot be kept by force. It can only be achieved by understanding.”

“Two things are infinite: the universe and human stupidity; and I’m not sure about the universe.”

“He who joyfully marches to music rank and file, has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would surely suffice. This disgrace to civilisation should be done away with at once. Heroism at command, how violently I hate all this, how despicable and ignoble war is; I would rather be torn to shreds than be a part of so base an action. It is my conviction that killing under the cloak of war is nothing but an act of murder.”

Albert Einstein, the Grandfather of Fission Energy

Energy production is the only viable way away from militarisation of Fission Energy. In the same way fire is harnessed in a fireplace to warm our homes or make our steels, Invisible Fire, Fission Energy, Energy from the Atom, does the same.

We are blessed by people like Alvin Weinberg who dedicated their lives to the cause after witnessing how their scientific endeavours were employed with such militaristic zeal for death and destruction.

“Weinberg realised that you could use Thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. … his team built a working reactor … and he spent the rest of his 18-year tenure trying to make Thorium the heart of the nation’s atomic power effort. He failed. Uranium reactors had already been established, and Hyman Rickover, defacto head of the US nuclear program, wanted the plutonium from uranium-powered nuclear plants to make bombs. Increasingly shunted aside, Weinberg was finally forced out in 1973.”

Episode 20 – Got a LFTR? What’s Under the Hood – Unintended Consequences – Chapter 8 Part 4

Liquid Fluoride Thorium Reactor by fmilluminati

How a LFTR works

In one type of LFTR, a liquid Thorium salt mixture circulates through the reactor core, releasing neutrons that convert Thorium 232 in an outer, shell-like “jacket” to Thorium 233. Thorium 232 cannot sustain a chain reaction, but it is fertile, meaning that it can be converted to fissile U-233 through neutron capture, also known as “breeding.”

Space LFTR by fmilluminati
Newcastle Molten Salt Burner

When a Uranium 233 atom absorbs a neutron, it fissions (splits), releasing huge amounts of energy and more neutrons that activate more Thorium 232. In summary, a LFTR turns Thorium-232 into U-233, which thoroughly fissions while producing only 10% as much “waste” as LWRs produce.

How Thorium “Burns”

“Thorium energy can help check CO2 and global warming, cut deadly air pollution, provide inexhaustible energy, and increase human prosperity. Our world is beset by global warming, pollution, resource conflicts, and energy poverty. Millions die from coal plant emissions. We war over mideast oil. Food supplies from sea and land are threatened. Developing nations’ growth exacerbates the crises. Few nations will adopt carbon taxes or energy policies against their economic self-interests to reduce global CO2 emissions. Energy cheaper than coal will dissuade all nations from burning coal. Innovative Thorium energy uses economic persuasion to end the pollution, to provide energy and prosperity to developing nations, and to create energy security for all people for all time.”

Dr. Robert Hargraves

Dr. Robert Hargraves has written articles and made presentations about the liquid fluoride Thorium reactor and energy cheaper than from coal – the only realistic way to dissuade nations from burning fossil fuels. His presentation “Aim High” about the technology and social benefits of the liquid fluoride Thorium reactor has been presented to audiences at Dartmouth ILEAD, Thayer School of Engineering, Brown University, Columbia Earth Institute, Williams College, Royal Institution, the Thorium Energy Alliance, the International Thorium Energy Association, Google, the American Nuclear Society, the President’s Blue Ribbon Commission of America’s Nuclear Future, and the Chinese Academy of Sciences. With coauthor Ralph Moir he has written articles for the American Physical Society Forum on Physics and Society: Liquid Fuel Nuclear Reactors (Jan 2011) and American Scientist: Liquid Fluoride Thorium Reactors (July 2010). Robert Hargraves is a study leader for energy policy at Dartmouth ILEAD. He was chief information officer at Boston Scientific Corporation and previously a senior consultant with Arthur D. Little. He founded a computer software firm, DTSS Incorporated while at Dartmouth College where he was assistant professor of mathematics and associate director of the computation center. He graduated from Brown University (PhD Physics 1967) and Dartmouth College (AB Mathematics and Physics 1961).

Episode 19 – Want a Lift? Grab a LFTR – Unintended Consequences – Chapter 8 Part 3

Dr Alvin Weinberg at ORNL Stylised

What’s a LFTR?

A thoriumfuelled MSR [Molten Salt Reactor] is a Liquid Fluoride Thorium Reactor – a LFTR

Pronounced ‘LIFTER
A Lifetime of power in the palm of your hand [with Thorium]

With a half-life of 14 billion years, Thorium-232 is one of the safest, least radioactive elements in the world. Thorium-232 emits harmless alpha particles that cannot even penetrate skin, but when it becomes Th-233 in a Molten Salt Reactor, it becomes a potent source of power. Sunlight, living at high altitude and the emissions from your granite counter-top or a coal-burning plant are more hazardous than thorium-232.

LFTRs are even more fuel-efficient than uranium- fuelled MSRs, and they create little waste because a LFTR consumes close to 99% of the thorium-232. LWRs reactors consume just 3% of their uranium before the rods need to be changed. That’s like burning just a tiny part of a log while polluting the rest with chemicals you must store for years.

Just one pound of thorium can generate as much electricity as 1700 tons coal, so replacing coal-burning plants with LFTRs would eliminate one of the largest causes of climate change. That same pound (just a golf ball-size lump), can yield all the energy an individual will ever need, and just one cubic yard of thorium can power a small city for at least a year. In fact, if we were to replace ALL of our carbon-fuelled, electrical power production with LFTRs, we would eliminate 30 to 35% of all man-made greenhouse gas production.

From 1977 to 1982, the Light Water Reactor at Shippingport, Pennsylvania was powered with thorium, and when it was eventually shuttered, the reactor core was found to contain about 1% more fissile material (U233/235) than when it was loaded. (Thorium has also fuelled the Indian Point 1 facility and a German reactor.)

India, which has an abundance of thorium, is planning to build Thorium-powered reactors, as is China while we struggle to overcome our unwarranted fear of nuclear power. And in April, 2015, a European commission announced a project with 11 partners from science and industry to prove the innovative safety concepts of the Thorium-fuelled MSR and deliver a breakthrough in waste management.

Supplies

Thorium is four times as plentiful as uranium ore, which contains only 1% U-235. Besides being almost entirely usable, it is 400 times more abundant than uranium’s fissile U-235. Even at current use rates, uranium fuels can last for centuries, but thorium could power our world for thousands of years.

Just 1 ton of thorium is equivalent to 460 billion cubic meters of natural gas. We already have about 400,000 tons of thorium ore in “storage”, and we don’t need to mine thorium because our Rare-Earth Elements plant receives enough thorium to power the U. S. every year. Australia and India tie for the largest at about 500,000 tons, and China is well supplied.

A 1 GW LWR requires about 1.2 tons of uranium each year, but a 1 GW LFTR only needs a one-time “kick start” of 500 pounds of U-235 plus 1 ton of thorium each year.

Waste and Storage

Due to their high efficiency, LFTRs create only 1% of the waste that conventional reactors produce, and because only a small part of that waste needs storing for 400 years – not the thousands of years that LWR waste requires – repositories much smaller than Yucca mountain would easily suffice.

Furthermore, LFTRs can run almost forever because they produce enough neutrons to make their own fuel, and the toxicity from LFTR waste is 1/1000 that of LWR waste. So, the best way to eliminate most nuclear waste is to stop creating it with LWRs and replace them with reactors like MSRs or LFTRs that can utilize stored “waste” as fuel.

With no need for huge containment buildings, MSRs can be smaller in size and power than current reactors, so ships, factories, and cities could have their own power source, thus creating a more reliable, efficient power grid by cutting long transmission line losses that can run from 8 to 15%. Unfortunately, few elected officials will challenge the carbon industries that provide millions of jobs and wield great political power. As a consequence, thorium projects have received little to no help from our government, even though China and Canada are moving toward thorium, and India already has a reactor that runs on 20% thorium oxide.

India on the road map of tripling nuclear power capacity

After our DOE signed an agreement with China, we gave them our MSR data. To supply its needs while MSRs are being built, China is relying on 27 conventional nuclear reactors plus 29 Generation III+ (solid fuel) nuclear plants that are under construction. China also intends to build an additional fifty-seven nuclear power plants, which is estimated to add at least 150 GigaWatts (GW) by 2030.

Nuclear Scientists Head to China to Test Experimental Reactors, by Stephen Stapczynski

China to start building 6-8 new nuclear reactors in 2018

“Global increase in nuclear power capacity in 2015 hit 10.2 gigawatts, the highest growth in 25 years driven by construction of new nuclear plants mainly in China…. We have never seen such an increase in nuclear capacity addition, mainly driven by China, South Korea and Russia,.. It shows that with the right policies, nuclear capacity can increase.”

MIT: China Is Beating America In Nuclear Energy

In 2016, the Chinese Academy of Sciences allocated $1 billion to begin building LFTRs by 2020. As for Japan, which began to restart its reactors in 2015, a FUJI design for a 100 to 200 MW LFTR is being developed by a consortium from Japan, the U. S. and Russia at an estimated energy cost of just three cents/kWh. Furthermore, it appears that five years for construction and about $3 billion per reactor will be routine in China.

Dr. Reşat Uzmen

Since the 1960’s Turkey were trying to get involved with nuclear energy. Turkey was one of the countries that participated in the International Conference on the Peaceful Uses of Atomic Energy, held in Geneva in 1955 September. There is no doubt that Turkey wants to use nuclear energy for energy production. In Turkey, there are many experts that have knowledge about nuclear fission technology. Dr. Reşat Uzmen is one of the most important people who is experienced in the nuclear fuel area. During the interview, his ideas and visions enlighten us about the future of Molten Salt Fission Technology. Here is another instructive interview for building a MSR!

The Atoms for Peace symbol was placed over the door to the American swimming pool reactor building during the 1955 International Conference on the Peaceful Uses of Atomic Energy in Geneva, often called the Atoms for Peace conference.

Leading to Nuclear Interview Series, Interview #3, Dr Resat Uzmen of Figes Turkey

Mr. Reşat, can you tell us a little about yourself?

I graduated from İstanbul Technical University (İTU) in the chemical engineering department. I did my master’s degree in İTU also. As soon as I finished the department I became a researcher in The Çekmece Nuclear Research and Training Center, known as ÇNAEM. My research was about how uranium could be treated to obtain an uranium concentrate. I did my doctor’s degree in that topic. Back then, it was so hard to get information because it is a delicate technology. That’s why we did the research by ourselves. Think about that: there was no internet! There was a library in ÇNAEM, it still remains there. All the reports that were collected from all over the world were kept here. We benefit from those reports that were about uranium and thorium. In addition, getting chemicals was difficult. The ores that we were working on were coming from Manisa so mine was tough to process. Despite all these obstacles Turkey needed uranium so we have done what has to be done. I am the founder of “the nuclear fuel technology department in ÇNAEM”. This department was focused on producing uranium fuel that could be ready for fuelling and we did it. We produced uranium pellets by ourselves in our laboratories. We did research about ore sorting of thorium and how it can be used in nuclear reactors. Now I am working as a nuclear technology director at FİGES.

Dr. Reşat Uzmen, Thorium NTE Field in Burdur Turkey

“Turkey is capable of designing its own reactor now!”

Dr. Reşat Uzmen

What are your thoughts on Turkey’s nuclear energy adventure? Although nuclear engineering education has been given at Hacettepe University since 1982, Turkey has never been able to gain an advantage in nuclear energy. What could be the main reasons for this?

Nuclear energy needs government support and government incentive. Government policy must include nuclear energy. In Turkey, nuclear energy was too personal. A government is formed then a team becomes the charge of the Turkey Atomic Energy Agency and this team is working hard, trying to encourage people about nuclear energy but then the new government is formed and the team is changed. Unfortunately, this is how it is done in Turkey. Also, you need money to build reactors. There were some countries that try to build a nuclear reactor in Turkey. Once CANDUs was very popular in Turkey. Canadians supported us a lot. Argentineans came with CAREM design and wanted to develop the design with Turkey also they wanted to build CAREM in Turkey, it was a great offer but the politicians at that time were not open up to this idea. Nuclear energy must be government policy and it should not be changed by different governments.

As you know, there is a PWR-type reactor under construction in cooperation with Rosatom and Akkuyu in our country. Do you think Turkey’s first reactor selection was the right choice?

This cooperation is not providing us any nuclear technology. When The Akkuyu Nuclear Power Plant is finished we will have a nuclear reactor that is operating in Turkey but we can not get any nuclear technology transformation. Right now Turkey can not construct the sensitive components of a nuclear reactor. Akkuyu is like a system that produces energy for Turkey. It would be the same thing if Russia build that plant in a place that is near Turkey. In addition, there is the fate of spent fuels. Russia takes away all the spent fuels, these spent fuels can be removed from Turkey in two ways: by water, starting from the Akkuyu harbor, the ship will pass through the Turkish straits, then pass to the Black Sea and pass through the Novorossiysk harbor to reach Siberia and by land, from Akkuyu it will arrive in Samsun or Trabzon then by water the ship will arrive in Siberia. I suppose spent fuels are going to be transported by water.

What are your thoughts on molten salt reactors?

Molten Salt Reactor is a Gen. 4 reactor and has a lot of advantages. First of all, the fuel of the MSR is molten salt so it is a liquid fuel. Since I am interested in the fuel production part of nuclear energy I am aware of the challenges of solid fuel production. Having liquid fuel is a big virtue. Liquid fuel can be ThF4-UF4. The fuel production step can proceed as: UF4 may be imported as enriched uranium. If you have the technology then UF₆ may be imported as enriched uranium then UF₆ can be converted to UF4. After that step fabrication of the liquid fuel is easier than solid fuel. Second, MSR has a lot of developments in the safety systems of a nuclear reactor. There is no fuel melting danger because it is already melted. The liquid fuel is approximately 700 °C. The important point is molten salt may freeze. If fuel temperature is below approximately 550°C the fuel becomes solid we don’t want that to happen. Also, the fuel has a negative temperature coefficient which means that as the temperature of the fuel rises reactivity of the fuel is going to decrease. There is a freeze plug at the bottom of the core. If the core overheats the freeze plug will melt and the contents of the core will be dropped into a containment tank fed by gravity. This is a precaution against the loss of coolant accident. One of the other advantages is reprocessing opportunity. It is possible with helium to remove volatile fission products from the reactor core. Tritium can be a problem but if the amount of tritium is below the critical level then it wouldn’t be a problem.

” Molten Salt Reactors are advantageous in many ways. The fuel is already melted, freeze plug is going to melt in case of an overheating issue, reproccessing is easier than the solid fuel. ”

FİGES took on the task of designing MSR’s heat exchangers in the SAMOFAR project and your designs were approved. Can you talk a bit about heat exchangers? What are the differences with a PWR exchanger? Why did it need to be redesigned?

There are a lot of differences between a PWR heat exchanger and an MSR heat exchanger. The basic difference is, that in a PWR heat exchanger steam is produced from water. MSR heat exchanger is working with molten salt to produce steam. FİGES finished calculations like the flow rate of the molten salt, the temperature of the molten salt, etc. for a heat exchanger of SAMOFAR. The heat exchanger is made of a material that is the same as the reactor core. In SAMOFAR, Hastelloy is used but boron carbide sheeting may be used for the heat exchanger.

Can you talk a little bit about your collaboration with Thorium Network?

The Founder of the Thorium Network Jeremiah has contacted FİGES about 5 months ago. We met him in one of the FİGES offices which are located in İstanbul. We have discussed what we have done in Turkey thus far. We signed an agreement about sharing networks. We share the thorium and molten salt reactor-based projects with them and they do the same.

If the idea of building an MSR in Turkey is accepted, where will FİGES take part in this project?

As FİGES, building an MSR in Turkey has two steps. The first step is about design. To design a reactor you need software. The existing codes are for solid fuel. First of all the codes that are going to be used for liquid fuel must be developed. There are companies that work to develop required software all around the world. We want to take part in the design step as FİGES. After the design is finished the second step comes. The second step is building the reactor. FİGES doesn’t have the base to build a reactor but an agreement can be made with companies that can build a nuclear power plant.

Do you have any advice you can give to nuclear power engineer candidates who want to work on MSR? What can students do about it?

There are tons of documents about Molten Salt Reactor Technology. These documents are about the material of the reactor core, software codes, design, etc. A student can find everything about MSR on the internet. In addition to this, students should follow the Denmark-based company that is called “Seaborg“. They have a compact molten salt reactor design. Also, there is another MSR design called “ThorCon“. Students can follow the articles, presentations, and events about these two MSR designs. As I said, students must research and follow the literature about Molten Salt Fission Technology.

. . .

It was a great opportunity for me to meet Mr. Reşat who has been working to develop nuclear energy in Turkey. I would like to thank him for his time and great answers.

As students, we are going to change the world step by step with Molten Salt Fission Technology by our side. We are going to continue doing interviews with key people in nuclear energy and MSR!

Episode 18 – Pass the Salt Dear – How Fission Gets Rock Solid Stability – Unintended Consequences – Chapter 8 Part 2

What’s an MSR? A Molten Salt Reactor of Course!

Molten Salt Reactors are superior in many ways to conventional reactors.

In a Molten Salt Reactor, the uranium (probably Thorium in the future), is dissolved in a liquid fluoride salt. (Although fluorine gas is corrosive, fluoride salts are not.) Fluoride salts also don’t break down under high temperatures or high radiation, and they lock up radioactive material, which prevents it from being released to the environment.

As noted earlier, Dr. Alvin Weinberg’s Oak Ridge MSR ran successfully for 22,000 hours during the sixties. However, the program was shelved, partly for political reasons and partly because we [USA] favoured Admiral Rickover’s water-cooled reactors.

Schematic of a Molten Salt Reactor

When uranium or thorium is combined with a liquid fluoride salt, there are no pellets, no zirconium tubes and no water, the source of the hydrogen that exploded at Chernobyl and Fukushima. The fluid that contains the uranium is also the heat-transfer agent, so no water is required for cooling. MSRs are also more efficient than LWR plants because the temperature of the molten salt is about 1300 F [700 C], whereas the temperature of the water in a conventional reactor is about 600 F [315 C], and higher heat creates more high-pressure steam to spin the turbines.

Thorium Debunk

This extra heat can also be used to generate more electricity, desalinate seawater, split water for hydrogen fuel cells, make ammonia for fertilizer and even extract CO2 from the air and our oceans to make gasoline and diesel fuel. In addition, MSRs can be fueled with 96% of our stored uranium “waste” – spent fuel – and the fissile material in our thousands of nuclear bombs.

Why Hydrogen Needs Nuclear Power To Succeed by By Alan Mammoser – Mar 07, 2021

Hydrogen: The best shot for nuclear sustainability? by Susan Gallier, Nuclear News Dec 4, 2021

Because some MSR designs do not need to be water-cooled, those versions don’t risk a steam explosion that could propel radioactive isotopes into the environment. And because MSRs operate at atmospheric pressure, no huge, concrete containment dome is needed.

When the temperature of the liquid salt fuel rises as the chain reaction increases, the fuel expands, which decreases its density and slows the rate of fission, which prevents a “runaway” reaction. As a consequence, an MSR is inherently self-governing, and because the fuel is liquid, it can easily drain by gravity into a large containment reservoir. As a consequence, the results of a fuel “spill” from an MSR would be measured in square yards, not miles.

In the event of a power outage, a refrigerated salt plug at the bottom of the reactor automatically melts, allowing the fuel to drain into a tank, where it spreads out solidifies, stopping the reaction. In effect, MSRs are walk-away- safe.

Even if you abandon an MSR, the fuel will automatically drain and solidify without any assistance.

If the Fukushima reactor had been an MSR, there would have been no meltdown, and because radioactive by-products like caesium, iodine and strontium bind tightly to stable salts, they would not have been released into the environment. (In 2018 Jordan agreed to purchase two, 110 MW, South Korean molten salt reactors,)

USEFUL MSR BYPRODUCTS

Besides producing CO2-free electricity, fissioning U-233 in an MSR creates essential industrial elements that include xenon, which is used in lasers, neodymium for super-strength magnets, rhodium, strontium, medical molybdenum-99, zirconium, ruthenium, palladium, iodine-131 for the treatment of thyroid cancers and bismuth-213, which is used for targeted cancer treatments.

“Perfect technology”

The raw material is cheap and available worldwide, not even cooling water is needed and the waste is less and decays much faster than conventional nuclear waste: Thorium technology stands for a new quality of the use of nuclear energy

Wolfgang Kaufmann 23.01.2022

中国中部甘粛省の武威近くにある紅沙港工業団地では、パイロットプラントが間もなく稼働し、中国だけでなく世界中のエネルギー生産に革命を起こす可能性があります。 化石燃料の使用による二酸化炭素の排出、風力タービンの景観の劣化、環境に有害な生産による電池の大量使用、風や曇りのない天候での停電、リスクはありません。原子炉の事故による放射能の増加は、革新的なトリウムベースの溶融塩原子炉によって約束されています。 上海応用物理研究所のトリウムベースの溶融塩原子炉No.1(TMSR-LF1)は、原子力エネルギーの使用における新しい品質を表しており、それに「グリーンコート」を与えることになっています。

In the Hongshagang Industrial Park near Wuwei in the central Chinese province of Gansu, a pilot plant will go into operation in the near future, which has the potential to revolutionize energy production not only in the Middle Kingdom, but throughout the world. No more carbon dioxide emissions as a result of the use of fossil fuels, no more landscape degradation by wind turbines, no mass use of batteries from environmentally harmful production, no power outages in calm winds and clouds, but also no radiation risk due to reactor accidents, all this promises the innovative Thorium-based Molten Salt Reactor-Liquid Fuel No. 1 (TMSR-LF1) of the Shanghai Institute of Applied Physics, which advocates a new quality of use of the Nuclear energy is in place and this should give it a kind of “green coat of paint”.

Yoichiro Shimazu – FUJI Molten Salt Reactor [MSR] Passive Heat Removal System @ ThEC12

TMSR-LF1トリウム液体塩原子炉の機能は比較的簡単です。 弱放射性元素のトリウムは液体の塩に溶解し、中性子を照射します。 これにより、核分裂時に大量の熱を放出する同位体ウラン233が生成されます。 したがって、原子炉は独自の燃料を生成します。最終的に、このプロセスは、従来の原子炉の運転よりもはるかに安全であり(以下を参照)、他にも多くの利点があります。

The operation of the Thorium Molten Salt reactor TMSR-LF1 is relatively simple. The weakly radioactive element Thorium is dissolved in molten salt and bombarded with neutrons. This produces the isotope uranium 233, the fission of which releases large amounts of heat. So the reactor produces its own fuel. This process ultimately brings much more safety than the operation of classic nuclear reactors (see below) and also a variety of other advantages.

6つの恩恵

Six Benefits

まず、必要なトリウム232はごく少量です。 イタリアのノーベル物理学賞を受賞したカルロ・ルビアが計算したところ、1トンのトリウムのエネルギー含有量は200トンのウラン金属または2800万トンの石炭のエネルギー含有量に相当するためです。

First, only extremely small amounts of Thorium 232 are needed. The energy content of one ton of Thorium corresponds to that of 200 tons of uranium metal or 28 million tons of coal, as the Italian Nobel Laureate in Physics Carlo Rubbia calculated.

第二に、世界中に主要なトリウム鉱床があります。 原則として、この元素は鉛と同様の頻度で岩石地殻に発生し、希土類の採掘における廃棄物としても発生します。 それが高価ではない理由です。 一方で、最近、従来の原子力発電所の数が再び大幅に増加しているため、ウランの不足や価格の高騰が見込まれます。

Secondly, there are larger Thorium deposits all over the world. In principle, the element occurs in the rock crust as often as lead and is also produced as a waste product in the extraction of rare earths. That’s why it’s not expensive. On the other hand, there is a risk of shortages and price explosions for uranium in the future, because the number of conventional nuclear power plants has recently increased significantly again.

第三に、トリウム溶融塩反応器は、例えば砂漠地域を含む事実上どこにでも建設することができる。冷却水を必要としないからです。

Thirdly, a Thorium Molten Salt reactor can be built virtually anywhere, including desert regions, for example. Because it does not require any cooling water.

第四に、そのオペレーション(原典はドイツ語であるので、この場合ビトリーブとなりうるか)はまた、大幅に少ない放射性廃棄物を生成します。また、TMSR-LF1からの核廃棄物の99%以上は、遅くとも300年後には無害な同位体に崩壊したと言われています。さらに、より高度な溶融塩反応器で後でより長い放射材料の少量の残留量を処理し、したがって完全に中和することができる。比較すると、ウランを動力源とする従来の原子炉は、使用される核燃料のほんの一部しか使用されていないにもかかわらず、数千年の半減期を持つ長寿命の放射性核分裂生成物を生成します。

Fourthly, its operation also generates significantly less radioactive waste. In addition, more than 99 percent of the nuclear waste from the TMSR-LF1 is said to have decayed into harmless isotopes after 300 years at the latest. Furthermore, it is possible to process the small residual amounts of longer radiating material later in more advanced molten salt reactors and thus completely neutralise. By way of comparison, conventional nuclear reactors powered by uranium produce long-lived radioactive fission products with half-lives of many thousands of years, even though only a small fraction of the nuclear fuel used is used.

第五に、トリウム溶融塩炉の建設と運転のコストは、通常使用される軽水炉のコストよりも低い。これは主に、システムの動作圧力が低いため、多くの安全上の注意が不要であること、および燃料棒を調達する必要がないという事実によるものです。

Fifthly, the costs for the construction and operation of Thorium Molten Salt reactors are lower than those of the light-water reactors that are usually used. This is mainly due to the low operating pressure of the systems, which makes numerous safety precautions superfluous, as well as the fact that no fuel rods have to be procured.

第六に、TMSR-LF1のような原子炉は、ウラン233がインキュベートされるだけでなく、核医学などで必要とされる他の多くの放射性核分裂生成物も生成されるため、非常に経済的に運転することができます。そして、放射性核種のいくつかは、ルビジウム、ジルコニウム、モリブデン、ルテニウム、パラジウム、ネオジム、サマリウムなどの非常に求められている元素にさえ変わります。同様に、希ガスキセノンが放出され、とりわけ絶縁媒体として、またレーザーおよび航空宇宙技術において使用される。

Sixthly, reactors such as the TMSR-LF1 can also be operated extremely economically because not only uranium 233 is incubated in them, but also many other radioactive fission products are produced, which are required, for example, in nuclear medicine. And some of the radionuclides even turn into highly sought-after elements such as rubidium, zirconium, molybdenum, ruthenium, palladium, neodymium and samarium. Likewise, the noble gas xenon is released, which is used, among other things, as an insulation medium as well as in laser and aerospace technology.

戦争は万物の父

War is the father of all things

TMSR-LF1の基礎となる技術は、中国ではなく米国で発明されました。早くも1954年には、空軍は長距離爆撃機に動力を供給するために小型の溶融塩原子炉を実験しました。しかし、このプロジェクトは、米国が大陸間弾道ミサイルを保有していたときに急速に終了しました。同様に、1970年代初頭、ユーリッヒ原子力研究施設の西ドイツの科学者は、溶融塩炉に関するいくつかの研究を発表しましたが、当時の原子炉開発責任者ルドルフ・シュルテンの消極的な態度のために最終的に注目されませんでした。

The technology underlying the TMSR-LF1 was not invented in China, but in the USA. As early as 1954, the Air Force experimented with a small molten salt reactor to power long-range bombers. However, the project came to a rapid end when the United States had intercontinental ballistic missiles. Likewise, at the beginning of the 1970s, West German scientists from the Jülich nuclear research facility presented some studies on molten salt reactors, which ultimately received no attention because of the negative attitude of the then head of reactor development, Rudolf Schulten [main developer of the pebble bed reactor design, a non fluid fuel system].

代替原子炉の受け入れの欠如のもう一つの理由は、世界中の原子力産業の関心の絶対的な欠如でした。古典的な原子炉では、優れたお金を稼ぐことができ、燃料棒の生産からの収入なしには誰もやりたがらなかった。したがって、腐食のリスクが高いとされるものや、誰かが原子炉を誤用して兵器級の核分裂性物質を製造するという仮説的な危険性など、溶融塩反応器の使用に反対するあらゆる種類のふりをした議論が持ち込まれた。

Another reason for the lack of acceptance of the alternative reactor type was the absolute lack of interest of the nuclear industry around the world. With the classic nuclear reactors, excellent money could be earned, and no one wanted to do without the income from the production of fuel rods. Therefore, all sorts of pretended arguments against the use of molten salt reactors were brought into play, such as the allegedly higher risk of corrosion and the hypothetical danger that someone will misuse the reactors to produce weapons-grade fissile material.

これは、中華人民共和国が2011年以来、TMSR-LF1の開発に4億ユーロ相当を投資することを妨げていない。結局のところ、北京の指導者たちは、2050年までに中国を「クライメートニュートラル」にするという野心的な目標を追求しており、溶融塩反応器の「完璧な技術」は絶対に不可欠であることを証明することができるだろう。

This has not prevented the People’s Republic of China from investing the equivalent of 400 million euros in the development of the TMSR-LF1 since 2011. After all, Beijing’s leaders are pursuing the ambitious goal of making the Middle Kingdom “climate neutral” by 2050, and the “perfect technology” of molten salt reactors could prove absolutely indispensable.

現在ゴビ砂漠の端でテストされている原子炉は、当初の公称出力はわずか2メガワットです。これは、約1000世帯にしか電力を供給できないことを意味します。しかし、TMSR-LF1の設計原理が成功すれば、出力373メガワットのトリウム溶融塩反応器の最初のプロトタイプが2030年頃までに稼働し、その後、中国全土で同じプラントが急速に連続して稼働します。ドイツが今なお原子力から遠ざかり続けるのか、それとも今も「グリーン原子力エネルギー」に頼っているのかは、まだ分からない。

The reactor, which is now to be tested on the edge of the Gobi Desert, initially has a nominal output of only two megawatts. This means that it can only supply around 1000 households with electricity. If the design principle of the TMSR-LF1 proves successful, however, the first prototype of a Thorium Molten Salt reactor with an output of 373 megawatts would go into operation by around 2030, which will then be followed by identical plants throughout China in rapid succession. It remains to be seen whether Germany will still remain in its abstinence from nuclear power at this time or whether it will now also rely on “green nuclear energy”.

Responsible for the Thorium-based Molten Salt Reactor-Liquid Fuel No. 1: The Shanghai Institute of Applied Physics

THORIUM-FLÜSSIGSALZREAKTOREN Kernreaktoren, in denen der Kernbrennstoff in Form geschmolzenen Salzes vorliegt, bieten eine Fülle von Vorteilen. In China wird in nächster Zukunft eine Versuchsanlage in Betrieb gehen

THORIUM MOLTEN SALT REACTORS Nuclear reactors in which the nuclear fuel is in the form of molten salt offer a wealth of advantages. A test plant will go into operation in China in the near future.

„Perfekte Technologie“

Der Ausgangsstoff ist billig und weltweit vorhanden, nicht einmal Kühlwasser wird benötigt und der Müll wird weniger und verfällt viel schneller als herkömmlicher Atommüll: Die Thorium-Technologie steht für eine neue Qualität der Nutzung der Kernenergie

Wolfgang Kaufmann, 23.01.2022

“Perfect technology”

The raw material is cheap and available worldwide, not even cooling water is needed and the waste is less and decays much faster than conventional nuclear waste: Thorium technology stands for a new quality of the use of nuclear energy

Wolfgang Kaufmann 23.01.2022

Im Hongshagang-Industriepark bei Wuwei in der zentralchinesischen Provinz Gansu wird in nächster Zukunft eine Versuchsanlage in Betrieb gehen, die das Potential besitzt, nicht nur die Energieerzeugung im Reich der Mitte, sondern in der ganzen Welt zu revolutionieren. Keine Kohlendioxidemissionen mehr infolge der Nutzung fossiler Brennstoffe, keine Landschaftsverschandelung durch Windräder, kein massenhafter Einsatz von Akkus aus umweltschädlicher Produktion, keine Stromausfälle bei Windstille und Bewölkung, aber auch kein Strahlungsrisiko aufgrund von Reaktorhavarien, alles das verspricht der innovative Thorium-based Molten Salt Reactor-Liquid Fuel No. 1 (TMSR-LF1) des Shanghai Institute of Applied Physics, der für eine neue Qualität der Nutzung der Kernenergie steht und dieser quasi einen „grünen Anstrich“ geben soll.

In the Hongshagang Industrial Park near Wuwei in the central Chinese province of Gansu, a pilot plant will go into operation in the near future, which has the potential to revolutionize energy production not only in the Middle Kingdom, but throughout the world. No more carbon dioxide emissions as a result of the use of fossil fuels, no more landscape degradation by wind turbines, no mass use of batteries from environmentally harmful production, no power outages in calm winds and clouds, but also no radiation risk due to reactor accidents, all this promises the innovative Thorium-based Molten Salt Reactor-Liquid Fuel No. 1 (TMSR-LF1) of the Shanghai Institute of Applied Physics, which advocates a new quality of use of the Nuclear energy is in place and this should give it a kind of “green coat of paint”.

Die Funktionsweise des Thorium-Flüssigsalzreaktors TMSR-LF1 ist relativ einfach. Das schwach radioaktive Element Thorium wird in Flüssigsalz aufgelöst und mit Neutronen beschossen. Dadurch entsteht das Isotop Uran 233, dessen Spaltung große Wärmemengen freisetzt. Der Reaktor produziert also seinen Brennstoff selbst. Dieses Verfahren bringt letztlich sehr viel mehr Sicherheit als der Betrieb klassischer Kernreaktoren (siehe unten) und darüber hinaus auch noch eine Vielzahl weiterer Vorteile.

The operation of the Thorium Molten Salt reactor TMSR-LF1 is relatively simple. The weakly radioactive element Thorium is dissolved in molten salt and bombarded with neutrons. This produces the isotope uranium 233, the fission of which releases large amounts of heat. So the reactor produces its own fuel. This process ultimately brings much more safety than the operation of classic nuclear reactors (see below) and also a variety of other advantages.

Sechs Vorteile

Six Benefits

Zum Ersten werden nur äußerst geringe Mengen an Thorium 232 benötigt. Denn der Energiegehalt einer Tonne Thorium entspricht der von 200 Tonnen Uran-Metall oder 28 Millionen Tonnen Kohle, wie der italienische Physik-Nobelpreisträger Carlo Rubbia errechnete.

First, only extremely small amounts of Thorium 232 are needed. The energy content of one ton of Thorium corresponds to that of 200 tons of uranium metal or 28 million tons of coal, as the Italian Nobel Laureate in Physics Carlo Rubbia calculated.

Zum Zweiten gibt es überall auf der Welt größere Thorium-Vorkommen. Im Prinzip kommt das Element in der Gesteinskruste ähnlich häufig vor wie Blei und fällt zudem als Abfallprodukt bei der Förderung von Seltenen Erden an. Deshalb ist es auch nicht teuer. Dahingegen drohen perspektivisch Verknappungen und Preisexplosionen beim Uran, weil die Zahl der konventionellen Kernkraftwerke neuerdings wieder deutlich zunimmt.

Secondly, there are larger Thorium deposits all over the world. In principle, the element occurs in the rock crust as often as lead and is also produced as a waste product in the extraction of rare earths. That’s why it’s not expensive. On the other hand, there is a risk of shortages and price explosions for uranium in the future, because the number of conventional nuclear power plants has recently increased significantly again.

Zum Dritten kann ein Thorium-Flüssigsalzreaktor praktisch überall errichtet werden, also beispielsweise auch in Wüstenregionen. Denn er benötigt keinerlei Kühlwasser.

Thirdly, a Thorium Molten Salt reactor can be built virtually anywhere, including desert regions, for example. Because it does not require any cooling water.

Zum Vierten entstehen bei seinem Betrieb auch deutlich weniger radioaktive Abfälle. Außerdem sollen über 99 Prozent des Atommülls aus dem TMSR-LF1 nach spätestens 300 Jahren in harmlose Isotope zerfallen sein. Des Weiteren besteht die Möglichkeit, die geringen Restmengen an länger strahlendem Material später in fortgeschritteneren Flüssigsalzreaktoren zu verarbeiten und damit gänzlich zu neutralisieren. Zum Vergleich: In mit Uran betriebenen konventionellen Atommeilern fallen langlebige radioaktive Spaltprodukte mit Halbwertszeiten von vielen tausend Jahren an, obwohl nur ein kleiner Bruchteil des verwendeten Kernbrennstoffs genutzt wird.

Fourthly, its operation also generates significantly less radioactive waste. In addition, more than 99 percent of the nuclear waste from the TMSR-LF1 is said to have decayed into harmless isotopes after 300 years at the latest. Furthermore, it is possible to process the small residual amounts of longer radiating material later in more advanced molten salt reactors and thus completely neutralise. By way of comparison, conventional nuclear reactors powered by uranium produce long-lived radioactive fission products with half-lives of many thousands of years, even though only a small fraction of the nuclear fuel used is used.

Zum Fünften liegen die Kosten für den Bau und Betrieb von Thorium-Flüssigsalzreaktoren niedriger als bei den sonst zumeist verwendeten Leichtwasser-Reaktoren. Das resultiert vor allen aus dem geringen Betriebsdruck der Anlagen, der zahlreiche Sicherheitsvorkehrungen überflüssig macht, sowie der Tatsache, dass keine Brennstäbe beschafft werden müssen.

Fifthly, the costs for the construction and operation of Thorium Molten Salt reactors are lower than those of the light-water reactors that are usually used. This is mainly due to the low operating pressure of the systems, which makes numerous safety precautions superfluous, as well as the fact that no fuel rods have to be procured.

Zum Sechsten lassen sich Reaktoren wie der TMSR-LF1 auch deshalb ausgesprochen wirtschaftlich betreiben, weil in ihnen nicht nur Uran 233 erbrütet wird, sondern zusätzlich noch viele andere radioaktive Spaltprodukte entstehen, die zum Beispiel in der Nuklearmedizin benötigt werden. Und manche der Radionuklide verwandeln sich sogar in ausgesprochen begehrte Elemente wie Rubidium, Zirconium, Molybdän, Ruthenium, Palladium, Neodym und Samarium. Desgleichen wird das Edelgas Xenon frei, das unter anderem als Isolationsmedium sowie in der Laser- und Raumfahrttechnik zum Einsatz kommt.

Sixthly, reactors such as the TMSR-LF1 can also be operated extremely economically because not only uranium 233 is incubated in them, but also many other radioactive fission products are produced, which are required, for example, in nuclear medicine. And some of the radionuclides even turn into highly sought-after elements such as rubidium, zirconium, molybdenum, ruthenium, palladium, neodymium and samarium. Likewise, the noble gas xenon is released, which is used, among other things, as an insulation medium as well as in laser and aerospace technology.

Der Krieg ist aller Dinge Vater

War is the father of all things

Erfunden wurde die dem TMSR-LF1 zugrunde liegende Technologie nicht in China, sondern in den USA. Dort experimentierten die Luftstreitkräfte bereits ab 1954 mit einem kleinen Flüssigsalzreaktor, der zum Antrieb von Langstreckenbombern dienen sollte. Das Projekt fand jedoch ein rapides Ende, als die Vereinigten Staaten über Interkontinentalraketen verfügten. Ebenso legten bundesdeutsche Wissenschaftler aus der Kernforschungsanlage Jülich zu Beginn der 1970er Jahre einige Studien über Flüssigsalzreaktoren vor, die letztlich wegen der ablehnenden Haltung des damaligen Leiters der Reaktorentwicklung, Rudolf Schulten, keine Beachtung fanden.

The technology underlying the TMSR-LF1 was not invented in China, but in the USA. As early as 1954, the Air Force experimented with a small molten salt reactor to power long-range bombers. However, the project came to a rapid end when the United States had intercontinental ballistic missiles. Likewise, at the beginning of the 1970s, West German scientists from the Jülich nuclear research facility presented some studies on molten salt reactors, which ultimately received no attention because of the negative attitude of the then head of reactor development, Rudolf Schulten [main developer of the pebble bed reactor design, a non fluid fuel system].

Ein weiterer Grund für die fehlende Akzeptanz des alternativen Reaktortyps war das absolute Desinteresse der Nu-klearindustrie rund um die Welt. Mit den klassischen Atommeilern ließ sich hervorragend Geld verdienen, und auf die Einnahmen aus der Herstellung von Brennstäben wollte auch niemand verzichten. Deshalb wurden allerlei vorgeschobene Argumente gegen den Einsatz von Flüssigsalzreaktoren ins Spiel gebracht, wie beispielsweise das angeblich höhere Korrosionsrisiko und die hypothetische Gefahr, dass jemand die Meiler missbraucht, um waffenfähiges Spaltmaterial zu produzieren.

Another reason for the lack of acceptance of the alternative reactor type was the absolute lack of interest of the nuclear industry around the world. With the classic nuclear reactors, excellent money could be earned, and no one wanted to do without the income from the production of fuel rods. Therefore, all sorts of pretended arguments against the use of molten salt reactors were brought into play, such as the allegedly higher risk of corrosion and the hypothetical danger that someone will misuse the reactors to produce weapons-grade fissile material.

Dies hat die Volksrepublik China nicht davon abgehalten, seit 2011 umgerechnet 400 Millionen Euro in die Entwicklung des TMSR-LF1 zu investieren. Schließlich verfolgt die Pekinger Führung das ehrgeizige Ziel, das Reich der Mitte bis 2050 „klimaneutral“ zu machen, und dabei könnte sich die „perfekte Technologie“ der Flüssigsalzreaktoren als absolut unverzichtbar erweisen.

This has not prevented the People’s Republic of China from investing the equivalent of 400 million euros in the development of the TMSR-LF1 since 2011. After all, Beijing’s leaders are pursuing the ambitious goal of making the Middle Kingdom “climate neutral” by 2050, and the “perfect technology” of molten salt reactors could prove absolutely indispensable.

250 MW Molten Salt Fission Energy Power Facility

Der Reaktor, der nun am Rande der Wüste Gobi erprobt werden soll, hat erst einmal nur eine Nennleistung von zwei Megawatt. Damit kann er lediglich um die 1000 Haushalte mit Strom versorgen. Sollte sich das Konstruktionsprinzip des TMSR-LF1 bewähren, dann würde allerdings bis etwa 2030 der erste Prototyp eines Thorium-Flüssigsalzreaktors mit 373 Megawatt Leistung in Betrieb gehen, dem dann in schneller Folge identische Anlagen in ganz China folgen. Ob Deutschland zu diesem Zeitpunkt immer noch in seiner Atomkraft-Abstinenz verharrt oder inzwischen auch auf die „Grüne Kernenergie“ setzt, bleibt abzuwarten.

The reactor, which is now to be tested on the edge of the Gobi Desert, initially has a nominal output of only two megawatts. This means that it can only supply around 1000 households with electricity. If the design principle of the TMSR-LF1 proves successful, however, the first prototype of a Thorium Molten Salt reactor with an output of 373 megawatts would go into operation by around 2030, which will then be followed by identical plants throughout China in rapid succession. It remains to be seen whether Germany will still remain in its abstinence from nuclear power at this time or whether it will now also rely on “green nuclear energy”.

Interview #2, Mr. Emre Kiraç of Kiraç Group. Part of the Student Guild Interview Series, “Leading to Nuclear”

Kirac Montage

Under favour of The Thorium Network, I met a successful and farsighted person. The person who caught my attention with his works and ideas in various fields is Emre Kıraç, CEO of Kıraç Group. If we talk about him briefly, Mr. Emre received his bachelor’s degree in electrical engineering from Istanbul Technical University. After completing his master’s degree in Entrepreneurial Management at London EBS (European Business School), he still works as the general manager of Kıraç Group companies operating in the fields of energy, transportation and health. If I were to talk about Mr. Emre for myself, I can say that he is open to new ideas and a model to young entrepreneurs with his success in many sectors he has entered. As a nuclear engineer, the thing that draws my attention the most is his innovative views, support and work in the field of energy. The reason why I say so is that, as we know, the need for energy is increasing day by day due to the increasing population and other factors. There are many different methods to supply with the energy need. One of them is nuclear energy. We see that Mr. Emre closely follows and supports the developments in the nuclear field.

Without further ado, you can see what we asked in our interview. Good reading!

Rana,
President of the Student Guild

Leading to Nuclear Interview Series, Interview #2, Engineer Emre Kiraç of Kiraç Group, Turkey

Can you tell us about the development of Kıraç Group? Since 1982, your company has continued to grow. What is your biggest source of motivation?

Our company’s history and the fact that we have earned people’s confidence in the workplace. Moreover, one of our major sources of motivation is to ensure and improve the continuation of our businesses. 

In which areas and specifically on which subjects does Kıraç Group focus on R&D studies?

In particular, we have four companies engaged in R&D work. These companies develop their own products. Kıraç Metal is working on solar energy systems, Kıraç Galvaniz is working on highway protection systems, Kıraç Bilişim is working on hospital automation, and Kıraç HTS is working on aviation.

You’ve worked in the energy business for a long time and have a lot of experience in it. I’d want to hear your own thoughts on nuclear energy and reactors.

Nuclear energy, in my opinion as an electrical engineer, is a healthy and safe source of energy. Of course, if it’s done correctly. There have unfortunately been awful examples of this in the past. Unfortunately, many associate nuclear energy with nuclear weapons, and as a result, they are biased towards this sort of energy. But, with smart design and hard effort, I’m confident that many people will see nuclear power as clean and safe.

As Kıraç Group, you give importance to green energy. You have studies and activities on solar energy and wind energy. The world also needs nuclear energy and we cannot stop climate change with wind and solar energy alone. What do you think about Turkey’s adventure in the field of nuclear energy? What changes will happen after that?

As we know, Akkuyu nuclear power plant installation has started. Of course, our country does not have any nuclear technology. In fact, nuclear technology is a technology that has been on the world agenda since the 1940s. Although Turkey has technology in many fields, unfortunately it has not had any technology in the nuclear field. Therefore, our country should develop itself in the global conjuncture.

Do you find Turkey’s studies on renewable energy sufficient? What do you think should be done more?

The main country that creates the economy of renewable energy is Germany. In this sector, we continue our work in Germany. Although this country is less efficient in terms of solar energy compared to other countries, it has many more solar power plants. In Turkey, on the other hand, solar power plants will definitely become more widespread. We are also in this business. Turkey is a complete renewable energy country in terms of both wind and solar energy. We also closely follow the hydrogen-based energy technology. Renewable energy should become more widespread in our country. Our country is very clear in this regard. The important thing is to increase the incentives of the state to this sector.

What are your thoughts on molten salt reactors? Can a molten salt reactor be established in Turkey after the VVER 1200 (PWR) to be established in Akkuyu and can it be produced entirely with national resources?

I got detailed information on this subject. The implementation of this technology would be incredibly good for Turkey. Since Turkey is rich in thorium reserves, this technology carries our country much further in the nuclear field. But for this technology to be applicable, R&D studies are needed. I think this will be possible with the efforts of our state and universities.

Can you tell us about your cooperation with Thorium Network? What prompted you to make this collaboration? What was the most influential factor for you?

First of all, since we are in the energy sector, Thorium Network attracted our attention. We have an old friendship with Mr. Jeremiah. I am interested in Jeremiah’s blogs and I follow them. After he came to Turkey, I had the opportunity to get to know him better. In addition to these, I feel responsible for this issue as Eskişehir has thorium deposits. I want to promote and develop Thorium Network in this environment. This is my biggest goal right now.

What kind of work can be done to spread the idea of nuclear energy in Turkey?

We need to lobby on this issue. People like you and us need to understand this technology very well and explain it to other people. We are just at the beginning of the road. Firstly, the Molten Salt Reactor technology needs to be developed. The more R&D studies we do on this subject, the more positive returns will be.

Turkey wants to design and install a molten salt reactor with completely domestic and national resources. Especially the Turkish Energy, Nuclear and Mining Research Institute (TENMAK) is very enthusiastic about this issue. Do you think TENMAK and universities alone will be enough for R&D studies or do we need other organizations?

We need an international communication on this issue. There may also be a need for the private sector, but we do not have many companies that have worked in the nuclear field. Together we can research and develop. Apart from these, it is important for the state to support, technical and commercial reports should be prepared and funds should be allocated. Then an international partner can be found and brought to better places.

When I examined your company, the years you entered new sectors caught my attention. You identify the needs very clearly and produce solutions in the most effective way. What do you pay attention to when entering a new industry? In your opinion, if the first molten salt reactor were to be successfully established in our country, where would Kıraç Group be in this process? (Part production, liquid fuel production, construction, electricity etc.)

The nuclear industry is a very large and complex field. We have thousands of products, of course, we can meet some of them in the future. But it’s too early to talk about that. We will cooperate with Thorium Network on this issue. There is also a large thorium reserve and precious metals in Eskişehir. These mines are currently being sold. It would be much better if we were in a position to add value to these mines. We continue our research on this subject.


We had a great time during the interview. We’d like to show our thanks to Mr. Emre for the information he gave and for his participation.

Bruce Power - A Nuclear Generating Station

World’s first reactor was built in 1942 in Chicago by Enrico Fermi and his team. Since then several hundred nuclear reactors were built, shut downed and rebuilt. For the future, six types of Generation 4 fission machines wait to be born. The world needs the energy to develop and maintain life but above all these reasons there is an essential one: going to Mars and supplying all energy that is needed for life. That’s my priority motivation and purpose for choosing the nuclear area to work. History tells us that “never forget to take lessons from past” and future tells us that “enlighten your ways from your mistakes”. The nuclear accidents that happened in the past led us to Gen 4 designs. As students, we are the ones who determine the nuclear reactor’s destiny. One of the Gen 4 designs is Molten Salt Reactor. We are trying to understand what can we do to design and build a molten salt reactor. We do this by interviewing nuclear experts, engineers all over the world. Come and join our story!

The Student Guild’s first interview was with Professor Akira Tokuhiro. He recently stepped down as the Dean of the Faculty of Energy Systems and Nuclear Science at Ontario Tech University in Canada. Also, he was in the American Nuclear Society’s President’s Committee on the 2011 Fukushima Daiichi nuclear power plant accident in Japan. He is an international nuclear energy expert.

Interview 001, Prof Akira Tokuhiro of Ontario Tech University – Leading to Nuclear Interview Series

What does nuclear energy expert do?

We do many things. We design Generation 4 (IV) systems. We look at the safety issues of current reactors and reactors that will be constructed. We are always looking for continuous safety improvements. We have 4 questions to be answered about safety and accidents, “what can happen, how often can it happen, how does it happen and what are the consequences?”. We ask these questions and we do the engineering design, safety analysis for that. Now nuclear engineering requires computer programming and engineering analysis. Applications of virtual reality, augmented reality, new applications of artificial intelligence, and machine learning will be used by new nuclear engineers to design and operate reactors.

In one of your interviews, you said “Nuclear reactors are challenging, that’s why I choose the nuclear energy area to work”. What is the most complex and challenging thing in the nuclear area or reactor physics?

For me, the most interesting and challenging thing is you have to know many things. You may find the solution for a small area but nuclear power plant is many different things. If you find a solution for a small area, it may impact other things. That’s why you have to look at many different things and you have to integrate them. That’s challenging for me. That integration that I teach to my students. How do you design a reactor? You design from the reactor core and then outward from the core.

What are the most common safety design features for Gen 4 that at the same time can be used for Gen 3 or Gen 2 reactor safety designs?

We have learned from Generation 2, 3 and 3+ about human factors engineering. There are two things about human beings, one is human beings are unreliable, other is unpredictable. When you apply these to safety systems, you want to design the reactor that minimizes probability for human error. Gen 4 and small modular reactors are designed so that cooling is assured, and do not rely on human operators because they can make mistakes under pressure. You have to design the reactor so that after shutdown decay heat can be removed without human intervention.

What is the biggest problem about safety that must be redesigned immediately now? For example, for PWR Generation 2 designs, what is the biggest safety problem about that reactor, and how can it be redesigned?

My opinion is reactor is designed so that it can shut down when a postulated event occurs. Even if an earthquake happens, the reactor can shut down like the reactors are located at Fukushima. The reactor was shut down after the earthquake. To remove the decay heat that’s remaining, pumps may be required to facilitate cooling for the first 72 hours. After two weeks the decay heat has to be much less. That has to change in all plants. Cooling after shut down is possible, we can do that but we have to make sure that even if we have a terrible earthquake, sufficient cooling has to remove thermal energy from the core. In SMR’s we don’t need pumps, like large reactors; when you have a pump, you also need a source of water in order to maintain cooling to take the heat. The safety problem of Gen 2 and Gen 3 designs is to prevent the meltdown of the core.

“By 2030 or 2035 Gen 4 large reactors or small modular reactors will be built by Russia or China.”

When do you think the first Gen 4 reactor will be built and where will it be built and which design will be built?

I think by 2030 or 2035 some Gen 4 reactors will be built. It may be Gen 4 large reactors but it is also possible that small modular reactor may be built too. It depends on the country. Russia and China have their designs and they are being constructed. It is difficult to call them Gen 4 but recent VVER is an improved design. China is building different kinds of reactors and operating them. So by 2030 or 2035 Gen 4 large reactors or small modular reactors will be built by Russia or China. In the west, new reactors very much depends on investment. For example, in North America before 2035 there will be a small modular reactor constructed and ready to operate as well.

What are your thoughts about thorium molten salt reactors?

Thorium Molten Salt reactors combine interesting reactor design with a fresh look at a new type of fuel. In the least next 3-5 years, we need much more engineering to finish the design and to get the regulatory approval of the completed design. Since my background is from the US, I am familiar with US Nuclear Regulatory Commission and they will importantly ask safety questions about design basis accidents. If you don’t have a pump, as part of the design natural convection cools the reactor so it may be a preferred design. Molten salt reactors are an interesting design and thorium is a different type of fuel. Perhaps by analogy, the nuclear industry is very similar to a restaurant or the automotive sector. You have to have customers and people come to eat at a restaurant. You have to make a popular automobile and people have to trust the safety and they are buying the safety in design that comes with it. Thorium Molten Salt design has to be finished and the design has to convince the regulator that it is a sufficiently safe design and that is constructed.

You are an expert on nuclear safety. Do you think passive safety systems designed for molten salt reactors are sufficient? Are there any other passive systems projects running? Can you please give us the details?

The molten salt reactor concept came from the 1950s and 1960s. Modernized design of the MSR started with Oak Ridge Molten Salt Reactor. (MSRE) They operated a research and demonstration reactor for a few years so fifty years later we are updating this design. I think the concept is solid but needs details; safety cases are convincing. If you have the money and engineers the first step to building a reactor is making a research and demonstration reactor to show that the reactor is very safe. For example, in molten salt reactors, fuel flows in a tank by gravity when an unanticipated event occurs. That is when a PS may be needed. So this means no operator, no human error.

“We need more nuclear power plants because we need a quick transition to a lower CO2 economy or scale.”

About thorium molten salt reactors, what can students do?

Now in the last five years, I think it is very important for students to find friends all over the world and to be interested in solving the challenges posed by climate change. We need to reach net-zero as quickly as possible: even before 2050. I think we have to make progress every five years or it will become very difficult to meet our net-zero carbon economy. We have to make as much progress by 2030. By 2050 we have to make substantial progress or net-zero carbon economy. If we don’t have any progress by 2030 reaching a net-zero carbon economy becomes increasingly difficult. Now we have the power of social media. Students have to ask many questions to old people like me about safety, design. We have to change and seek from the regulator, approval of the new reactors designs. We have a lot of experts from many countries. We already have about 440 nuclear power plants in the world but we need as many as ten times as many reactors to tackle climate change. We need more nuclear power plants because we need a quick transition to a lower CO2 economy or scale. It is not the ultimate solution for climate change but it is a solution that we have now. Young people can become involved through social media and by asking good questions. We need to convince people that by combining nuclear energy, wind, and solar we can reach a net-zero carbon economy. We need nuclear power, it may be risky, but risk and fear are a spectrum. If you think the benefit is greater than the risk then you would do it. People are usually afraid when they don’t understand the risk so they think the risk is very big and the benefit is not so big.

How did you decide to join the Thorium Network? What was the most attractive thing that impressed you about Thorium Network?

I contacted one of the founders Jeremiah Josey. I thought the thorium molten salt reactor is interesting and thorium is an alternative to uranium. It is a network. This network includes many people all around the world. That’s why I joined. The network is a new way to design a reactor.


I had a great time while talking with Professor Tokuhiro. I would like to thank him for his time and perfect answers.
