This is the use of 14 meV fusion neutrons to breed fuel for thermal nuclear reactors. Currently thermal nuclear reactors use for fuel, only the isotope of uranium, 235 U, which is 0.7% of the total resource.

Fusion Breeding: An Old, New Strategic Opportunity for Fusion

WebThe fuel breeding permits power reactors to operate longer before the amount of fissile material decreases to the point where reactor criticality is no longer manageable. The fuel breeding in the fuel cycle of all commercial light water reactors plays a significant role.

WebThis 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. WebJul 17, 2006 · This is why many breeder reactors are also fast reactors.

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.

WebThe thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material.In the reactor, 232 Th is transmuted into the fissile artificial uranium … 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…

Webapplication, the fusion-fission hybrid reactors can be further utilized as a neutron source for R&D of fusion reactor itself. Since 1986, many studies on the fusion-fission hybrid reactors have been performed to evaluate the feasibility and attractiveness of the hybrid systems for transmutation of nuclear wastes and breeding of fissile fuel [1~11].
