The major fissionable isotope of uranium used in nuclear power plants is ________

Question

Quizplus · Accepted Answer

Uranium-235 is the major fissionable isotope used in nuclear power plants. Uranium-238 is also used as a fuel, but it is not fissionable under thermal neutron conditions, and requires special reactor designs for its use. Uranium-236 and uranium-234 are relatively rare isotopes and are not used as fuel in nuclear power plants. The last option, uranium-235 and uranium-238, is partially correct as both isotopes are used in nuclear power generation, but the major fissionable isotope is uranium-235.
