Nuclear power in the United Kingdom generated 16.1% of the country's electricity in 2020. , the UK has 9 operational nuclear reactors at five locations (8 advanced gas-cooled reactors (AGR) and one pressurised water reactor (PWR)), producing 5.9 GWe.
It also has nuclear reprocessing plants at Sellafield and the Tails Management Facility (TMF) operated by Urenco in Capenhurst.
The United Kingdom established the world's first civil nuclear programme, opening a nuclear power station, Calder Hall at Windscale, England, in 1956. The British installed base of nuclear reactors used to be dominated by domestically developed Magnox and their successor AGR reactors with graphite moderator and coolant but the last of those are nearing the end of their useful life and will be replaced with "international" pressurised water reactors. At the peak in 1997, 26% of the nation's electricity was generated from nuclear power. Since then several reactors have closed and by 2012 the share had declined to 19%. The older AGR reactors have been life-extended, but they are now towards the end of their life.
In October 2010, the Cameron–Clegg coalition took forward the previous Labour government's plans for private suppliers to construct up to eight new nuclear power plants. The Scottish Government, with the backing of the Scottish Parliament, has stated that no new nuclear power stations will be constructed in Scotland. E.ON UK, RWE npower and Horizon Nuclear Power have been pulling out of their initial plans for developing new nuclear power plants, placing the future of nuclear power in the UK in some doubt. Despite this, EDF Energy is still planning to build four new reactors at two sites, with construction ongoing at Hinkley Point in Somerset. In light of the 2022 Russian invasion of Ukraine, the government of Boris Johnson announced a renewed commitment to nuclear power, using the EPR and potentially other PWR designs as well as yet-to-be-developed small modular reactors in a push towards energy independence and decarbonisation while replacing the ageing AGR reactors and phasing out gas and coal for electricity generation.

This course is intended to understand the engineering design of nuclear power plants using the basic principles of reactor physics, fluid flow and heat transfer. This course includes the following: Re
Wylfa nuclear power station (Atomfa'r Wylfa) is a Magnox nuclear power station undergoing decommissioning. Wylfa is situated west of Cemaes Bay on the island of Anglesey, off the northwestern coast of Wales. Construction of the two 490 MW nuclear reactors, known as Reactor 1 and Reactor 2, began in 1963. They became operational in 1971. Wylfa was located on the coast because seawater was used as a coolant. In 2012, Reactor 2 was shut down. Reactor 1 was switched off on 30 December 2015, ending 44 years of operation at the site.
Nuclear decommissioning is the process leading to the irreversible complete or partial closure of a nuclear facility, usually a nuclear reactor, with the ultimate aim at termination of the operating licence. The process usually runs according to a decommissioning plan, including the whole or partial dismantling and decontamination of the facility, ideally resulting in restoration of the environment up to greenfield status. The decommissioning plan is fulfilled when the approved end state of the facility has been reached.
EDF Energy is a British integrated energy company, wholly owned by the French state-owned EDF (Électricité de France), with operations spanning electricity generation and the sale of natural gas and electricity to homes and businesses throughout the United Kingdom. It employs 11,717 people, and handles 5.22 million business and residential customer accounts.
