Trawsfyndd Power Station, North Wales 1967

Located near the village of Trawsfynydd in Gwynedd, North Wales, Trawsfynydd Power Station was a pioneering nuclear power plant that played a significant role in Britain’s mid-20th-century energy programme. It was one of the few inland nuclear power stations in the UK, set within the rugged and scenic Snowdonia National Park.

Commissioned in the early 1960s, Trawsfynydd was a Magnox-type nuclear station, generating electricity using natural uranium fuel and carbon dioxide as a coolant. Its design reflected a transition from earlier conventional power stations to more advanced, cleaner energy sources.

Operating for nearly three decades, the power station contributed substantially to the regional electricity supply until it was permanently shut down in 1991. Since then, the site has undergone a complex decommissioning process, which is expected to continue for many years due to the challenges of safely dismantling nuclear infrastructure.
