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].

"WebUranium-233 ( 233U or U-233) is a fissile isotope of uranium that is bred from thorium-232 as part of the thorium fuel cycle. Uranium-233 was investigated for use in nuclear weapons and as a reactor fuel. [2] It has been used successfully in experimental nuclear reactors and has been proposed for much wider use as a nuclear fuel. " - Fission breeding
