Thorium can be converted into U-233 in a ____ reactor.
A
thermal
B
fast breeder
C
swimming pool
D
liquid metal cooled
Explanation: 

Detailed explanation-1: -Uranium-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.

Detailed explanation-2: -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-3: -Typically, when uranium 233 nucleus undergoes fission, the nucleus splits into two smaller nuclei (triple fission can also rarely occur), along with a few neutrons (the average is 2.48 neutrons per fission for thermal fission) and release of energy in the form of heat and gamma rays.
