GENERAL KNOWLEDGE

Detailed explanation-1: -Thorium-232 is converted into uranium-233 in a/an nuclear reactor. Explanation: The conversion of Thorium-232 into Uranium-233 is done in a fast breeder.

Detailed explanation-2: -Uranium-233 is produced by the neutron irradiation of thorium-232. When thorium-232 absorbs a neutron, it becomes thorium-233, which has a half-life of only 22 minutes. Thorium-233 decays into protactinium-233 through beta decay.

Detailed explanation-3: -A Fast Breeder Reactor (FBR) is a nuclear reactor that uses fast neutron to generate more nuclear fuels than they consume while generating power, dramatically enhancing the efficiency of the use of resources. Nuclear fission by fast neutron causes the increase in neutrons generated.

Detailed explanation-4: -fissile material naturally occurring uranium), plutonium-239, and uranium-233, the last two being artificially produced from the fertile materials uranium-238 and thorium-232, respectively.

Detailed explanation-5: -Pu239, which is created when U238 captures a neutron, forms U239 and then undergoes two beta decays, happens to be even better at fissioning than U235. Pu239 is formed in every reactor and also fissions as the reactor operates.
