Nuclear Fission and Fusion 2

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy nucleus into smaller nuclei, accompanied by the release of energy.

Front

What is a benefit of nuclear fission?

Back

The ability to release tremendous amounts of energy.

Front

What is an example of an uncontrolled fission reaction?

Back

Atomic Bomb.

Front

What is a disadvantage of nuclear energy?

Back

It leaves behind radioactive waste.

Front

What is the major drawback to nuclear fission reactors?

Back

The difficulty of achieving safe disposal of radioactive waste products.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing energy.

Front

What is the primary fuel used in nuclear fission reactors?

Back

Uranium-235.

Front

What is the role of a moderator in a nuclear reactor?

Back

A moderator slows down neutrons to sustain the fission chain reaction.

Front

What is the purpose of control rods in a nuclear reactor?

Back

Control rods absorb neutrons to regulate the fission process and maintain a safe reaction rate.

Front

What is radioactive waste?

Back

Radioactive waste is material that contains radioactive substances and poses a risk to health and the environment.
