Question: wind river coal is burned in a power plant which...

Question details
  1. 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.
  1. How many tons of coal will this plant burn in one year? One ton holds 2000 pounds.
  2. 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?
  3. 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.
