About Wylfa
Wylfa Nuclear Power Station is a former Magnox power station situated west of Cemaes Bay on the island of Anglesey, North 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 shutdown. Three years later, Reactor 1 was switched off on 30 December 2015 so ending 44 years of operation at the site. Wylfa Newydd is a proposed new nuclear station on a site adjacent to the old plant. An application to build two advanced boiling water reactors was submitted by Horizon Nuclear Power to the Office of Nuclear Regulation on 4 April 2017. HistoryWylfra was the second nuclear power station to be built in Wales after Trawsfynydd in 1959. Following the closure of Trawsfynydd in 1991, Wylfa became Wales' only nuclear power station. Construction of Wylfra, which was undertaken by British Nuclear Design & Construction (BNDC), a consortium backed by English Electric, Babcock & Wilcox Ltd and Taylor Woodrow Construction, began in 1963. The reactors were supplied by The Nuclear Power Group (TNPG) and the turbines by English Electric. These were the largest and last Magnox-type reactors to be built in the UK. Wylfa was also the second British nuclear power station, following Oldbury, to have a pre-stressed concrete pressure vessel instead of steel for easier construction and enhanced safety.
