How does the nuclear reactor work?

What is the primary function of a nuclear reactor?

• To burn fossil fuels

• To generate intense heat for power generation

• To store nuclear waste

• To create chemical reactions

Which of the following is NOT a component of a nuclear reactor?

• Fuel elements

• Moderator

• Turbine blades

• Control rods

What type of fuel is commonly used in nuclear reactors?

• Uranium-235

• Coal

• Natural gas

• Plutonium-239

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

• To increase the temperature

• To slow down

• To cool the reactor core

• To generate steam

Which material is frequently used as a moderator in nuclear reactors?

• Air

• Heavy water

• Oil

• Helium

What do control rods do in a nuclear reactor?

• Increase the speed of fission reactions

• Absorb excess neut

• Generate electricity

• Maintain the temperature

How do high-energy neutrons impact the fission process?

• They increase the reactor's efficiency

•  

  They escape and do not cause further fission

• They cool down the reactor

• They create steam

What happens when control rods are removed from the reactor?

• The reactor shuts down

• The fission reactions decrease

• The rate of fission reactions increases

• The reactor core becomes unstable

What is the main source of energy produced by a nuclear reactor?

• Chemical reactions

• Nuclear fission

• Solar energy

• Wind energy

What is the role of the pump in a nuclear reactor system?

• To cool the reactor

• To circulate water

• To generate electricity

• To control fission reactions
