Nuclear Power Plant

A major scientific concern over nuclear energy is how to--

• store the waste products safely

• reduce the high levels of carbon dioxide emitted into the air

• deal with the large amounts of fossil fuels required

• prevent the depletion of the ozone layer

What physical process in nuclear reactors is used to produce heat?

• Combustion

• Fission

• Fusion

• Conduction

What does the heat produced in a nuclear reactor do?

• It is used to cool down the reactor core.

• It is used to make steam that spins a turbine to create electricity.

• It is used to increase the temperature of the reactor for better efficiency.

• It is used to generate light.

What happens to the core water after it has been used in the heat exchanger in a PWR?

• It is discarded as waste

• It is cooled in the cooling tower

• It cycles back to the reactor to be reheated

• It is converted into steam for the turbine
