Trawsfynydd nuclear power station flasks were transported to Trawsfynydd on a section of the former Bala to Blaenau Ffestiniog railway that had been closed in January 1961. A single track was restored northwards with an entirely new line through the centre of Blaenau Ffestiniog that connected to the Conwy Valley branch. In 1963-4 a "Goliath" gantry crane was installed over sidings about east of the power station. Beginning on 20 April 1964, nuclear flasks could be transported by rail between destinations such as Sellafield in Cumbria. The last regular departure was on 8 August 1995.

Heysham nuclear power station 1 unit 1 will operate on six out of the eight boilers until a detailed repair strategy has been developed. The construction, which was undertaken by a consortium known as National Nuclear Corporation (NNC), began in 1979 and the station opened in 1988. Its generating capacity is 1250 MWe, and it is estimated to keep running until at least 2030. Heysham 2 shares its reactor design with Torness nuclear power station and is a development of the reactor design used at Hinkley Point B. The reactors were supplied by NNC and the turbines by NEI.
