Site Description The Central Electricity Generating Board's Magnox power station at Wylfa, was built in 1963 and designed to fit in with the landscape (a comprehensive landscaping scheme was was undertaken in which 100ft high artificial hills were constructed using excavated material). The main station building consisted of two reactor blocks linked by a common services building and the central control room. The fuelling and servicing machines were interchangeable between the reactors. The station used a dry store in which the irradiated fuel was stacked in nests of tubes filled with dry CO2 externally cooled by air. It had a capacity of 840 MW, and was the eighth and last first-generation Magnox station to be built by the CEGB. The station was officially opened in May 1972. Currently (2009) the station is still operational.

Wylfa Nuclear Power Station generated 'its last spark of electricity' on 30 December 2015. 'After decommissioning ends in 2026, the reactor buildings and stores for the Magnox fuel will be left untouched until they are safe to dismantle. That will be in about 90 years - around 2105.'
