Front

Which risk is associated with using nuclear fission to produce energy in a power plant?

Back

exposure of workers to radiation

Front

A serious risk factor associated with the operation of a nuclear power plant is the production of: acid rain, helium gas, greenhouse gases, such as CO₂, radioisotopes with long half-lives

Back

radioisotopes with long half-lives

Front

What is a problem commonly associated with nuclear power facilities?

Back

It is difficult to dispose of wastes.

Front

One benefit of nuclear fission reactions is

Back

production of energy

Front

Which components of a fission reactor are used to slow neutrons during a fission reaction?

Back

moderators

Front

Which substance can be used as both a coolant and a moderator in a nuclear reactor? Options: graphite, carbon dioxide, heavy water, helium

Back

heavy water

Front

Main function of a coolant in a nuclear fission reactor

Back

absorb energy produced by the reaction

Front

Control rods in nuclear reactors are commonly made of boron and cadmium because these two elements have the ability to:

• absorb neutrons
• emit neutrons
• decrease the speed of neutrons
• increase the speed of neutrons

Back

absorb neutrons

Front

The operation of a commercial nuclear reactor requires an isotope that will undergo:

Back

fission and a controlled chain reaction

Front

Purpose of high-density concrete in nuclear reactors

Back

shield the reactor personnel from radiation exposure
