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.”
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.
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).

The half-life of Thorium 232, which constitutes most of the earth’s Thorium, is 14 billion years, so it is not hazardous due to its extremely slow decay. – Dr. George Erickson
