Uranium was used to generate electricity in a nuclear reactor of a nuclear power station. The nuclear reactor was 29% efficient and the power output was 800MW. The fuel used in this plant contained 4% of pure uranium. The plant operated 365 days per year. The average price of the fuel during the first 20 years of operation of the plant was US$12/lb, but in last 20 years of operation, the price spiked to US$65/lb. Calculate the cost of fuel for the lifetime of the plant, 40 years
