Nuclear Reactor Safety and Design | GCSE Physics
Nuclear power plants use specialized components to control nuclear fission and ensure safety.
What is the function of control rods in a nuclear reactor?
What is Nuclear Reactor Safety and Design | GCSE Physics?
"The measures and components (like control rods and moderators) used to ensure a controlled chain reaction in a nuclear power plant."
Which type of radiation is stopped by a single sheet of paper?
Niels Bohr changed the atomic model by suggesting that electrons ____.
Which type of radiation is an electromagnetic wave?
What is the definition of half-life?
Controlling the Chain
Control Rods: Made of Boron; absorb neutrons to slow down the chain reaction.
Moderator: Usually water or graphite; slows down neutrons so they are easily absorbed.
Concrete Shielding: Thick walls that prevent ionising radiation from escaping.
Coolant: Carries away the heat energy produced by fission.
Practical Insight: Lowering the control rods into the reactor core stops the chain reaction by "soaking up" all the neutrons.
