The electric power generated by a single average size nuclear reactor block isbetween 400 and 800 MW. The fission of one 235U nucleus generates 185 MeVenergy on average. What is the total mass of the fuel rods ſoaded into a 630MW reactor for a one year period, if the fuel rods contain 5.50 percent of 235U?Assume that the overáll thermodýnamic efficiency of converting heat to electricenergy is 37.0 percent.

A nuclear power station delivers 1 GW of electricity for a year from uranium fission. Given that a single fission event delivers about 200 MeV of heat, estimate the number of atoms that underwent fission, their mass, and the loss of mass of the fuel elements.
The cross section for a 2.0-MeV neutron (a typical energy for a neutron released in ﬁ ssion) being absorbed by a 238U nucleus and producing ﬁ ssion is 0.68 barn. For a pure 238U sample of thickness 3.2 cm, what is the probability of a 2.0-MeV neutron producing ﬁ ssion? (p = 19 g/cm3 for uranium)
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 MWe electric power plant has a thermal power of approximately 3,000 MWth. What rate of fission reactions is required to produce this power? (Note: 1 eV = 1.6 × 10−19 J.) The reactor core consists of approximately 100 tonnes of UO2 (1 tonne = 1,000 kg), which is enriched in 235U 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 235U from occurring?
