The first was installed in 1712 close to Dudley Castle in the Black Country.

Nuclear Reaction: A Nuclear reaction in the nuclear core generates great amounts of energy in the form of heat. This energy is used to heat up water to steam to drive a steam turbine engine which generates rotary motion to a shaft which is mechanically connected to turn an Alternator which generates the electrical power.
