The amount of waste per KWh produced is among the lowest of all the fuels we use for energy production. Remember one truckload of fuel lasts about 6 years in a nuclear reactor (not all the fuel is replaced every 2-year refueling cycle, only about 1/3 of the fuel is replaced)..nuclear plants in the USA have a capacity factor of well over 90%, some near 99%, meaning a 630MW plant is pumping out 630MW 99% of the time.
A single BWR fuel rod (30,000 of them in a BWR-4 like DAEC) produces 2400MWh of electricity in its lifetime. A typical 460W PV panel will produce about 17MWh in its lifetime.
