A nuclear fission power plant produces about 2.00 GW of electrical power.Assume that that each fission produces 200.0 MeV of energy and that the mass of ²³⁵U consumed each day is 5.50 kg.The overall efficiency of the plant is

Question

Quizplus · Accepted Answer

The energy produced per fission is 200 MeV, which is equivalent to 3.2 x 10^-11 J. The number of fissions per day can be calculated from the mass of uranium consumed. The total energy produced per day is then the number of fissions multiplied by the energy per fission. The efficiency is the ratio of electrical power output to the total energy produced. Calculating this gives an efficiency of approximately 38.3%.
