Assume that 200 MeV are released per fission of the uranium nucleus 55. A nuclear reactor consumes 10 kg of U235 per day. Calculate its power output if the average energy released per U-235 fission is 200 MeV. 56. During a 10-hour run from one station to another, a railway engine develops an average power of 1200 kW. If the engine is driven by an atomic power plant of 20% efficiency, how much U235 would be consumed on the run? Each U235 atom on fission releases 180 MeV of energy. 57.
