What is the primary function of a nuclear reactor control system?

  1. To maintain a constant reactor power level

  2. To prevent reactor accidents

  3. To monitor reactor parameters

  4. To control the flow of coolant through the reactor


Correct Option: A
Explanation:

The primary function of a nuclear reactor control system is to maintain a constant reactor power level by adjusting the position of the control rods.

What type of sensor is used to measure the neutron flux in a nuclear reactor?

  1. Ionization chamber

  2. Proportional counter

  3. Geiger-Mueller counter

  4. Scintillation counter


Correct Option: A
Explanation:

Ionization chambers are used to measure the neutron flux in a nuclear reactor because they are sensitive to the ionization caused by neutrons.

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

  1. To absorb neutrons

  2. To reflect neutrons

  3. To moderate neutrons

  4. To cool the reactor core


Correct Option: A
Explanation:

Control rods are used to absorb neutrons in a nuclear reactor in order to control the reactor power level.

What is the difference between a nuclear reactor scram and a nuclear reactor shutdown?

  1. A scram is a rapid shutdown, while a shutdown is a gradual shutdown

  2. A scram is a manual shutdown, while a shutdown is an automatic shutdown

  3. A scram is a local shutdown, while a shutdown is a global shutdown

  4. A scram is a partial shutdown, while a shutdown is a complete shutdown


Correct Option: A
Explanation:

A scram is a rapid shutdown of a nuclear reactor that is initiated by the reactor protection system in response to a safety concern, while a shutdown is a gradual shutdown of a nuclear reactor that is initiated by the operator for maintenance or refueling.

What is the purpose of a nuclear reactor containment building?

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

  2. To protect the reactor core from damage

  3. To provide shielding for workers from radiation

  4. To control the flow of coolant through the reactor


Correct Option: A
Explanation:

The purpose of a nuclear reactor containment building is to prevent the release of radioactive material into the environment in the event of an accident.

What is the most common type of nuclear reactor in the United States?

  1. Pressurized water reactor

  2. Boiling water reactor

  3. Gas-cooled reactor

  4. Liquid metal fast breeder reactor


Correct Option: A
Explanation:

Pressurized water reactors are the most common type of nuclear reactor in the United States because they are relatively simple to design and operate.

What is the purpose of a nuclear reactor moderator?

  1. To slow down neutrons

  2. To speed up neutrons

  3. To absorb neutrons

  4. To reflect neutrons


Correct Option: A
Explanation:

The purpose of a nuclear reactor moderator is to slow down neutrons so that they are more likely to be absorbed by uranium atoms.

What is the purpose of a nuclear reactor coolant?

  1. To remove heat from the reactor core

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor coolant is to remove heat from the reactor core and transfer it to a heat exchanger, where it can be used to generate electricity.

What is the difference between a nuclear reactor fuel assembly and a nuclear reactor control rod?

  1. Fuel assemblies contain uranium fuel, while control rods contain neutron-absorbing material

  2. Fuel assemblies are located in the center of the reactor core, while control rods are located around the periphery of the reactor core

  3. Fuel assemblies are used to generate heat, while control rods are used to control the reactor power level

  4. All of the above


Correct Option: D
Explanation:

Fuel assemblies contain uranium fuel, while control rods contain neutron-absorbing material. Fuel assemblies are located in the center of the reactor core, while control rods are located around the periphery of the reactor core. Fuel assemblies are used to generate heat, while control rods are used to control the reactor power level.

What is the purpose of a nuclear reactor pressure vessel?

  1. To contain the reactor coolant

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor pressure vessel is to contain the reactor coolant and prevent it from leaking out.

What is the purpose of a nuclear reactor steam generator?

  1. To transfer heat from the reactor coolant to the secondary coolant

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor steam generator is to transfer heat from the reactor coolant to the secondary coolant, which is then used to generate electricity.

What is the purpose of a nuclear reactor turbine?

  1. To generate electricity

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor turbine is to generate electricity by converting the thermal energy of the steam produced by the reactor into mechanical energy.

What is the purpose of a nuclear reactor condenser?

  1. To condense the steam produced by the reactor turbine

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor condenser is to condense the steam produced by the reactor turbine back into water so that it can be reused.

What is the purpose of a nuclear reactor feedwater pump?

  1. To pump water from the condenser back into the reactor

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor feedwater pump is to pump water from the condenser back into the reactor so that it can be heated and turned into steam again.

What is the purpose of a nuclear reactor control room?

  1. To house the controls and instrumentation for the reactor

  2. To provide shielding for workers from radiation

  3. To control the flow of neutrons through the reactor core

  4. To prevent the release of radioactive material into the environment


Correct Option: A
Explanation:

The purpose of a nuclear reactor control room is to house the controls and instrumentation for the reactor so that operators can monitor and control the reactor's operation.
