The number of fissions per second in a nuclear reactor is calculated by dividing the total power output (in joules per second) by the energy released per fission. Each fission of uranium-235 or plutonium-239 releases about 200 MeV, which sustains the reactor’s thermal power.
How many fission take place per second in a 300 MW reactor, assuming each fission releases 200 MeV of energy?
