The UK was the first nation to introduce a civil nuclear energy programme, starting with Calder Hall at Windscale in 1956. The British Government soon rolled out an extensive programme of nuclear power plant development, with Wylfa being made operational in 1971.

Roy Dean joined the team at Wylfa in 1967, three years after worked started on site. He worked his way up the ranks, eventually becoming the station’s deputy superintendent. Upon his retirement in 1989, Dean was presented with this commemorative model plaque, made by the engineers in the power stations’ workshop.

Wylfa stopped producing power in 2015, when the second of two reactors was shut down.

Kindly donated to Oriel Môn’s museum collection by Roy Dean’s son, Dr Jonathan Dean.
