Wylfa Nuclear Power Station is a former Magnox power station situated west of Cemaes Bay. 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. Three years later, Reactor 1 was switched off on 30 December 2015 so ending 44 years of operation at the site. Wylfa Newydd (New Wylfa) 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. Initial testing and archaeological investigations were carried out but the plug was pulled in 2019
