Ten months after Rolls-Royce SMR emerged as the United Kingdom’s preferred bidder to build the U.K.’s first small modular reactors, the company and the U.K. government’s Great British Energy–Nuclear (GBE-N) have signed a contract allowing work to begin at the site of the decommissioned Wylfa nuclear plant in North Wales.

The United Kingdom has announced a northern Wales site as its preferred location for a third mega-nuclear power station as the nation aims to support long-term energy security.

Following its plans to build nuclear facilities at Hinkley in Somerset and Sizewell in Suffolk, both in England, U.K. officials hope to revive the nuclear history of Wylfa, in Wales, and bring thousands of jobs and major investment to the area. The government is kickstarting talks with global energy firms in hopes of building a nuclear plant in Wylfa that could provide enough energy to power 6 million homes for 60 years.

The United Kingdom’s Nuclear Decommissioning Authority (NDA) has announced the signing of a memorandum of understanding with Cwmni Egino to support the development of a small-scale nuclear project in North Wales.
