A 1 GW plant, (for 750,000 homes) consumes only 3 kg of nuclear fuel per day, costing about half as much as equivalent weight in Silver. The nuclear plant releases only steam, or clean warm water. Fuel cost is about one half cent per kWh, much less than consumer energy prices in California between $0.25 to $0.50 per kWh.
A comparable coal plant needs 9000 tons
of coal of day which is released into the atmosphere as ?3 times as much CO2, and includes toxic and radioactive materials such as mercury, that causes substantial brain damage. The fuel costs 3.5 times more. By weight U-235 (3% enriched) fuel produces 2.5 million times more energy than coal.
