A large nuclear power plant produces 1950 mw of electrical, Ask an Expert

Academics

A large nuclear power plant produces 1950 MW of electrical power by nuclear fission.

(a) By how many kilograms does the mass of the nuclear fuel decrease in one year? (Assume an efficiency of 35 percent for a nuclear power plant.)

(b) In a coal-burning power plant, each kilogram of coal releases 31 MJ of thermal energy when burned. How many kilograms of coal are needed each year for a 1950 MW coal-burning power plant? (Assume an efficiency of 36 percent for a coal-burning power plant.)
