What is the primary source of uranium for nuclear fuel?

  1. Uraninite

  2. Carnotite

  3. Pitchblende

  4. All of the above


Correct Option: D
Explanation:

Uraninite, carnotite, and pitchblende are all uranium-bearing minerals that are mined to extract uranium for nuclear fuel.

What is the process of increasing the concentration of uranium-235 in uranium ore called?

  1. Enrichment

  2. Conversion

  3. Fabrication

  4. Reprocessing


Correct Option: A
Explanation:

Enrichment is the process of increasing the concentration of uranium-235 in uranium ore by removing uranium-238.

What is the most common type of nuclear reactor used for electricity generation?

  1. Pressurized Water Reactor (PWR)

  2. Boiling Water Reactor (BWR)

  3. CANDU Reactor

  4. Magnox Reactor


Correct Option: A
Explanation:

Pressurized Water Reactors (PWRs) are the most common type of nuclear reactor used for electricity generation worldwide.

What is the primary purpose of a nuclear fuel assembly?

  1. To contain and support the nuclear fuel pellets

  2. To transfer heat from the fuel pellets to the coolant

  3. To control the nuclear reaction

  4. All of the above


Correct Option: D
Explanation:

Nuclear fuel assemblies are designed to contain and support the nuclear fuel pellets, transfer heat from the fuel pellets to the coolant, and control the nuclear reaction.

What is the primary radioactive waste product of nuclear power plants?

  1. Spent nuclear fuel

  2. High-level radioactive waste

  3. Low-level radioactive waste

  4. Transuranic waste


Correct Option: A
Explanation:

Spent nuclear fuel is the primary radioactive waste product of nuclear power plants and contains a mixture of uranium, plutonium, and other radioactive isotopes.

What is the primary method for managing spent nuclear fuel?

  1. Reprocessing

  2. Direct disposal

  3. Vitrification

  4. Deep geological disposal


Correct Option: D
Explanation:

Deep geological disposal is the primary method for managing spent nuclear fuel, which involves burying it deep underground in a stable geological formation.

What is the primary purpose of nuclear fuel reprocessing?

  1. To extract plutonium and uranium from spent nuclear fuel

  2. To reduce the volume of spent nuclear fuel

  3. To convert spent nuclear fuel into a form suitable for disposal

  4. All of the above


Correct Option: D
Explanation:

Nuclear fuel reprocessing is a process that extracts plutonium and uranium from spent nuclear fuel, reduces the volume of spent nuclear fuel, and converts it into a form suitable for disposal.

What is the primary purpose of a nuclear fuel cycle?

  1. To provide a sustainable supply of nuclear fuel

  2. To manage and dispose of nuclear waste

  3. To minimize the environmental impact of nuclear power

  4. All of the above


Correct Option: D
Explanation:

The primary purpose of a nuclear fuel cycle is to provide a sustainable supply of nuclear fuel, manage and dispose of nuclear waste, and minimize the environmental impact of nuclear power.

What is the primary isotope of uranium used in nuclear reactors?

  1. Uranium-235

  2. Uranium-238

  3. Uranium-234

  4. Uranium-236


Correct Option: A
Explanation:

Uranium-235 is the primary isotope of uranium used in nuclear reactors because it is fissile, meaning it can sustain a chain reaction.

What is the primary purpose of a nuclear fuel cladding?

  1. To prevent the release of radioactive materials into the environment

  2. To transfer heat from the fuel pellets to the coolant

  3. To control the nuclear reaction

  4. All of the above


Correct Option: D
Explanation:

Nuclear fuel cladding serves multiple purposes, including preventing the release of radioactive materials into the environment, transferring heat from the fuel pellets to the coolant, and controlling the nuclear reaction.

What is the primary purpose of a nuclear moderator?

  1. To slow down neutrons to increase the probability of fission

  2. To absorb neutrons to control the nuclear reaction

  3. To reflect neutrons back into the reactor core

  4. All of the above


Correct Option: A
Explanation:

The primary purpose of a nuclear moderator is to slow down neutrons to increase the probability of fission.

What is the primary purpose of a nuclear control rod?

  1. To absorb neutrons to control the nuclear reaction

  2. To reflect neutrons back into the reactor core
