Q
What do the control rods, moderator, heat exhanger and reactor vessel do in a nuclear power plant?
A
Control rods: absorb neutrons to control the power output + reduce the number of neutrons that are available for further fission. ( to maintaina constant rate of reaction.)
Moderator: slows neutrons down to effectively stimulate further fission
Heat exchanger: conveys energy from the reactor to the turbines.
Reactor vessel: contains the reactor core
