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

Explanation:

The energy contained per second in the fuel is:

It is know that fission of a gram of uranium liberates . Mass flow rate is computed herein:

The needed quantity of fuel per second is:

The annual fuel consumption is now obtained:

The cost of fuel for the lifetime of the plant is:

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
