Nuclear power is a clean and efficient way of boiling water to make steam, which turns turbines to produce electricity. Aside from the reactor itself, nuclear power stations work like most coal or gas-fired power stations.

Nuclear power plants can continuously generate large-scale, around-the-clock electricity for many months at a time, without interruption.

Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Currently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium.
