Question: wind river coal is burned in a power plant which...
- Wind River coal is burned in a power plant which turns heat energy into electrical energy at an efficiency of one third. This coal has a mean radioactive uranium (mass 238 compared to hydrogen at mass 1) content of 10 parts per million by weight. The power plant sells 1 GWatt (109 Watts) of electricity.
- How many tons of coal will this plant burn in one year? One ton holds 2000 pounds.
- Assume that this uranium stays in the solid waste (fly ash) from the plant. How many pounds of uranium are in the waste ash from this plant in one year?
- If it costs $500 a year to remove each pound of uranium from that waste, how much will this cleanup cost the power company each year? This cost will be passed on to the customers.
