Practise fission and fusion as energy sources, from reactor parts and chain reactions to product tables, energy estimates and comparison statements.
Energy is transferred from the Sun to the Earth.
Nuclear fusion happens in the Sun.
Which energy store of the Sun decreases during nuclear fusion?
chemical
kinetic
nuclear
thermal
Diagram 1 shows some of the stages of electricity generation in a nuclear power station.
Diagram 1
Nuclear fission takes place inside the reactor of the nuclear power station.
Give the name of a fuel that could be used in the reactor.
Energy is released from the fuel in the reactor by nuclear fission.
Describe the process of nuclear fission that takes place inside the reactor.
High pressure steam transfers energy from the reactor to a turbine.
The turbine spins as the steam passes through it.
Diagram 2 shows a simplified generator connected to the turbine.
Diagram 2
At night the power station does not need to generate as much electricity. Suggest how the output of this generator could be reduced.
Kori Nuclear Power Plant in South Korea is one of the world's largest nuclear fission power stations.
The reactors at Kori use nuclear fission to generate electricity.
The products released during nuclear fission have high energy in their kinetic store.
Give a product of nuclear fission.
