9.1 We want to get an idea of the actual mass of 235U involved in powering a nuclear power plant. Assume that a single fission event releases 200 MeV of thermal energy. A 1,000 MW, electric power plant has a thermal power of approximately 3,000 MWh- a. What rate of fission reactions is required to produce this power? (Note: 1 eV = 1.6 x 10-¹9 J.) b. The reactor core consists of approximately 100 tonnes of UO, (1 tonne = 1,000 kg), which is enriched in 2U to 4%. How many full-power years could the reactor operate if all of the 235U were to be fissioned? What factors prevent such complete depletion of the 235 U from occurring? C. Under the "U depletion scenario of part b, what mass of fission products and what mass of high-level wastes (HLW) would be produced?
