Multiple choice

What is the primary fuel used in nuclear power plants?

  1. Coal

  2. Natural Gas

  3. Uranium

  4. Oil
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Uranium is the primary fuel used in nuclear power plants because it is a fissile material, meaning it can undergo nuclear fission, a process that releases a large amount of energy.

Multiple choice

What is the process by which nuclear power plants generate electricity?

  1. Nuclear Fusion

  2. Nuclear Fission

  3. Radioactive Decay

  4. Nuclear Transmutation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nuclear power plants generate electricity through the process of nuclear fission, where the nucleus of a heavy atom, such as uranium or plutonium, is split into two or more smaller nuclei, releasing a large amount of energy.

Multiple choice

What is the term used to describe the radioactive waste produced by nuclear power plants?

  1. Nuclear Waste

  2. Spent Fuel
