The company has also been tasked with identifying potential sites for another large-scale nuclear power plant, similar to those being built at Hinkley Point in Somerset and Sizewell in Suffolk, which have the potential to power the equivalent of six million homes.
It will report back by autumn 2026, and has been requested by Energy Secretary Ed Miliband to consider sites across the UK, including in Scotland, officials said.
It is not clear whether the SMR plans, which are smaller and more straightforward to build, rule Wylfa out from being considered after it was designated the preferred location in 2024 by the previous UK Conservative government.
The decision to opt for small modular reactors at Wylfa was criticised by the US Ambassador Warren Stephens, who said he was “extremely disappointed” by the decision.
He had been urging ministers to commit to a large-scale plant, with US firm Westinghouse having reportedly presented plans to build a new gigawatt station at the site.
“If you want to get shovels in the ground as soon as possible and take a big step in addressing energy prices and availability, there is a different path, and we look forward to decisions soon on large-scale nuclear projects,” Mr Stephens said.
