Which two nuclear fuels are produced artificially?(a) 92Pu^239 and 92U^233(b) 92Pu^244 and 92U^234(c) 92Pu^241 and 92U^235(d) 92Pu^242 and 92U^236I got this question in quiz.The origin of the question is Gaseous Fuels & Nuclear Fuels topic in section Steam Power Plant of Energy Engineering

Answer»

Right choice is (a) 92Pu^239 and 92U^233

The EXPLANATION is: PLUTONIUM 92Pu^239 and URANIUM 92U^233 are the FISSIONABLE materials produced artificially from 92U^238 and 90Th^232 respectively. Uranium-238 and thorium 232 are available in nature. They are known as fertile materials. These fertile materials when placed close to 92U^235 in a reactor absorb the emitted NEUTRONS to produce fissionable materials as follows.
