Lesson details
Lesson outcome
I can describe how a nuclear power station produces energy for heating to generate electricity.
Show transcript
The fission of uranium-235 produces two daughter nuclei, two or more neutrons and gamma radiation.
In a nuclear power station, control rods absorb neutrons to control the rate at which U-235 fissions.
In a nuclear power station, a moderator absorbs the energy from gamma radiation and heats up.
Heating by the moderator, via a coolant, boils pure water turning it to steam.
The expansion of pure water turning to steam creates a driving force that spins a turbine.
