Prime Highlights:
Four micro nuclear reactors will be built at the decommissioned Llynfi power station in Bridgend, south Wales, each generating up to 20 MW of electricity.
The reactors will be modular, assembled off-site, and represent the first new nuclear power plant in the UK since 1995.
Key Background:
Britain is set to take a significant step toward its green energy future with the planned construction of the country’s first “micro” nuclear reactors at a former coal-fired power station in south Wales. Under the proposal, four reactors will be installed at the decommissioned Llynfi power station in Bridgend. Each reactor is expected to generate up to 20 megawatts (MW) of electricity, with modular assembly taking place off-site. This innovative project, spearheaded by Washington-based Last Energy, marks an important test for the UK government’s green energy policy.
This project represents the first commercial nuclear reactors to be built in the UK since 1978, when the Torness nuclear power station in East Lothian was completed. In fact, the last nuclear plant built in Britain was Sizewell B in Suffolk, which went operational in 1995. Unlike the larger small modular reactors (SMRs) that have been promised for years, these micro reactors are smaller but still have the potential to supply power to data centers, factories, and other industrial operations.
The micro reactors, while not designed for the domestic grid, could provide a reliable energy source to industrial sites, unaffected by fluctuations in wind or solar power. This approach aligns with efforts to ensure consistent energy supply to key sectors. The project is a significant milestone in the UK’s nuclear strategy, aligning with Sir Keir Starmer’s goals to accelerate nuclear energy deployment.
The government’s commitment to overcoming opposition and fast-tracking nuclear projects is also evident, with plans to allow reactor construction outside designated zones in England and Wales. If successful, Last Energy’s micro reactors could contribute to a more resilient energy infrastructure, helping to meet growing energy demands and alleviate grid constraints. The first reactor is expected to be operational by 2027, with the project backed by the Export-Import Bank of the United States. This pioneering venture promises to help shape the future of sustainable energy in Britain.
