One is needed to continue ... 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.

WebThe conditions required to start and maintain a fusion reaction make a fission-type accident or nuclear meltdown based on a chain reaction impossible. Nuclear fusion power plants will require out-of-this-world conditions — temperatures exceeding 100 million degrees Celsius to achieve high enough particle density for the reaction to take place. 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. WebThe number 1.4 is based off of the average number of neutrons given off by a fission reaction of uranium-235, which is 2.4. Only 1 neutron is needed for the fission chain reaction to be stable, so the remaining 1.4 neutrons … major function of frontal lobe
