Trawsfynydd
Trawsfynydd Site is located on a 15 hectare site in Snowdonia National Park, Gwynedd. As the only inland site, it drew cooling water from Llyn Trawsfynydd, which was formed in 1928 to retain water for Maentwrog Hydroelectric Station. Trawsfynydd generated 69 terawatt hours of electricity during 26 years of operation and shut-down in 1993.
The site is decommissioning and key successes include bulk asbestos removal and storage of all solid intermediate level waste, resins and liquid in the interim storage facility. Site infrastructure has been upgraded, redundant buildings demolished and the reactor safestores are being reconfigured in preparation for a major project to reduce their height by around two thirds.
