A)two-thirds from uranium-235 and one-third from uranium-239.
B)one-third from uranium-235 and two-thirds from uranium-239.
C)two-thirds from uranium-235 and one-third from plutonium-239.
D)one-third from uranium-235 and two-thirds from plutonium-239.

Question

Quizplus · Accepted Answer

The majority of the fission reactions in a nuclear power plant are from uranium-235 (about two-thirds), and the remaining energy comes from plutonium-239, which is created from uranium-238 through neutron capture and subsequent beta decay processes. Uranium-239 is not a stable isotope and does not significantly contribute to the fission process in a reactor.
