The electrical power output of a large nuclear reactor facility is 900 MW. It has a 35.0% efficiency in converting nuclear power to electrical.
(a) What is the thermal nuclear power output in megawatts?
(b) How many 235 U nuclei fission each second, assuming the average fission produces 200 MeV?
(c) What mass of 235 U is fissioned in one year of full-power operation?
