The energy released from fission is about 200 MeV per fission event or 3.2-10-11 J per 235U nucleus. The fission of 1 g of 235U generates about 1 MW of thermal power; thus, a reactor that contains 1 kg of 235U fuel generates about 1 GW (109 W). If the reactor core is immersed in a heat bath containing 8.7.105 liters of water (12 m x 6 m x 12 m) initially at 25°C, how long will it take for the water to begin to boil off? Assume that the heat capacity of water is constant and that there is no heat lost from the reactor coolant to the surroundings.
