The UK government should develop its next gigawatt-size nuclear power reactors after Sizewell C at the Wylfa site in north Wales and earmark the nearby Trawsfynydd site for the country’s first small modular reactors, a committee of MPs has concluded.

The Welsh affairs committee said in its latest report on nuclear energy in Wales that if the UK government is serious about nuclear energy it needs to pursue new gigawatt-scale plants alongside its policy on SMRs.

Government ambition on nuclear energy must be translated into action by pushing ahead with new reactors at the Wylfa nuclear power station in north Wales.

“We have heard from a wide range of industry representatives that Wylfa is one of the best sites for nuclear development and it is difficult to see how the UK government can deliver its nuclear ambitions without taking forward a project at Wylfa,” the committee said.
