What is the most common type of nuclear reactor?

  1. Pressurized water reactor (PWR)

  2. Boiling water reactor (BWR)

  3. Gas-cooled reactor (GCR)

  4. Heavy water reactor (HWR)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pressurized water reactors (PWRs) are the most common type of nuclear reactor in the world. They use ordinary water as both the coolant and the moderator.

Multiple choice

What is the purpose of a nuclear fuel?

  1. To provide energy for the reactor

  2. To control the rate of the nuclear reaction

  3. To absorb neutrons

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Nuclear fuel serves multiple purposes in a nuclear reactor. It provides energy for the reactor, controls the rate of the nuclear reaction, and absorbs neutrons.

Multiple choice

What is the most common type of nuclear fuel?

  1. Uranium-235

  2. Plutonium-239

  3. Thorium-232

  4. Deuterium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Uranium-235 is the most common type of nuclear fuel. It is a fissile isotope of uranium that can be used to sustain a chain reaction.

Multiple choice

What is the process by which a nuclear reactor generates electricity?

  1. Nuclear fission

  2. Nuclear fusion

  3. Radioactive decay

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nuclear reactors generate electricity through the process of nuclear fission. In nuclear fission, a heavy nucleus is split into two or more lighter nuclei, releasing a great amount of energy.

Multiple choice

What is the primary purpose of a nuclear moderator?

  1. To slow down neutrons

  2. To absorb neutrons

  3. To control the rate of the nuclear reaction

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary purpose of a nuclear moderator is to slow down neutrons. This is necessary because neutrons produced by nuclear fission are too fast to cause further fissions.
