As Keir Starmer announces SMRs to be built in Wales, US ambassador says Britain should choose ‘a different path’

Keir Starmer has announced that the UK’s first small modular nuclear reactors will be built in north Wales – but immediately faced a backlash from Donald Trump’s administration after it pushed for a US manufacturer to be chosen.

Wylfa on the island of Anglesey, or Ynys Môn, will be home to three small modular reactors (SMRs) to be built by British manufacturer Rolls-Royce SMR. The government said it will invest £2.5bn.

SMRs are a new – and untested – technology aiming to produce nuclear power stations in factories to drive down costs and speed up installation. Rolls-Royce plans to build reactors, each capable of generating 470 megawatts of power, mainly in Derby.
