Fusion breeding as an approach to sustainable energy

WebThe meaning of FISSION is a splitting or breaking up into parts. Most atoms do not fission, but the isotopes of certain elements, such as uranium-235, are fissile. — Washington … WebAug 11, 2014 · A breeder reactor is essentially a particular configuration of a fast reactor. Fast reactors generally have an excess of neutrons (due to low parasitic absorbtion), the neutrons given off by fission reactions can “breed” more fuel from otherwise non-fissionable isotopes or can be used for another purposes (e.g.,transmutation of spent nuclear fuel). ios shortcuts nfc tagWebThis is how 238 U contributes to the operation of nuclear reactors and the production of electricity through this plutonium. For example, at a burnup of 40GWd/tU, about 40% of the total energy released comes from bred plutonium. This corresponds to a breeding ratio for this fuel burnup of about 0.4 to 0.5. ios shortcuts play sound file

"WebJan 1, 2014 · Fusion-fission hybrids may also breed U-233 or Pu-239 . The blanket energy gain is used in calculating reactor power balance. Typical values of M are 1.1–1.2 without beryllium, 1.5–1.7 with beryllium, and M ~ 10 with fast fission of U-238. The value of M has a strong influence on net electrical power output and on reactor economics. " - Fission breeding

Breeder reactors could, in principle, extract almost all of the energy contained in uranium or thorium, decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors, which extract less than 1% of the energy in the uranium mined from the earth. The high fuel-efficiency of breeder reactors could greatly reduce concerns about fuel supply, energy used in mining, and storage of radioactive waste. With seawater uranium extraction (currently to… WebJun 1, 2009 · This paper shows that fusion breeding is a better way, one that could lead to substantial fusion power not too long after midcentury, and summarizes years of effort and advocacy for fusion breeding instead of conventional fusion. 7 PDF POSSIBLE PROLIFERATION RISKS OF FUTURE TOKAMAK FUSION REACTORS M.
