Nuclear power comes from heat that is generated during nuclear fission, when one atom splits into two. Most nuclear power plants use enriched uranium and plutonium as fuel.
In a nuclear reactor, the heat that is given off from this reaction is used to heat water, which creates steam, which drives the turbine, which spins a generator to produce power.
