Assume that the energy released by the fission of a single nucleus U-235 is about 200 MeV. A nuclear electric power plant produces heat by fission of U-235. It has a heat-to-electricity conversion efficiency of 35 %, and its capacity for electricity production is Pelectricity = 1000 MWelectricity. a. Calculate the energy released by the fission of all nuclei U-235 contained in a mass of 1 kg of uranium-235 in units of J and kWh. b. Using E= mc², calculate how much (in g) of the 1 kg U-235 mass has involved in nuclear reaction. c. Calculate the rate of U-235 consumption, in nuclei per second, using the plant efficiency provided and results obtained in part a. d. If there are initially 2000 kg of U-235 in the reactor, estimate the approximate time when the fuel will have to be replaced.
