There have been two nuclear reactors located in Wales; both are now being decommissioned. The nuclear power plant on the Trawsfynydd site came offline in 1991 and the plant on the Wylfa site in Anglesey stopped generating electricity in 2015. The Office for Nuclear Regulation (ONR) regulate nuclear sites in Great Britain and publish a map of licensed sites on their website at www.onr.org.uk/our-work/map-of-sites-and-facilities/. GE Healthcare operated a Nuclear Licensed site in Cardiff which was used for radiopharmaceutical manufacture and de-licensed in 2019. There was no reactor present on this site.
