Nuclear decay and nuclear energy – WJECGenerating power from nuclear fuels

Nuclear fission is the splitting of a radioactive nucleus to release energy. High-energy collisions between light nuclei can result in fusion, which releases energy.

Generating power from nuclear fuels

Nuclear reactors use the heat from nuclear reactions in the nuclear fuel to boil water. Just as in conventional power stations, the steam from the boiling water makes a turbine spin, which in turn makes the generator turn.

Unlike conventional power stations, however, nuclear power stations do not release carbon dioxide, so they do not contribute to global warming while in use.

Cold coolant is injected at the bottom. It passes into reactor vessel and through gaps in graphite core which hold moveable control rods.  The now hot coolant is siphoned out.

in the reactor itself is prevented from escaping by steel and concrete walls. This is important because can cause cancer. The waste from nuclear power stations is radioactive so it can be harmful too. Plutonium is a waste product from nuclear reactors. It can be used to make nuclear bombs.
