Site profile
Trawsfynydd decommissioning site, located on a 15.4 hectare site, on the northern bank of an inland lake in the heart of Snowdonia National Park, North Wales, is a twin reactor station now defuelled and being decommissioned. When operational the station produced enough electricity to meet the needs of a city the size of Manchester in the UK.
The decommissioning programme on site started in 1993 when defuelling commenced and is progressing well under the management of Magnox North as the tier 1 contractor overseeing the work carried out day-to-day by the Site Licence Company Magnox Electric Ltd.
