Rolls-Royce eyes Snowdonia nuclear site for first small modular reactor
14 Feb 2020 By Miles Rowland
Engineering firm Rolls-Royce has said that the first of its planned small nuclear reactors could be built at a site near Snowdonia National Park in Wales.
Speaking to the BBC today, Rolls-Royce chief technology officer Paul Stein said there was a “high probability” that Trawsfynydd would be the site of the first such reactor, which would be assembled from pre-manufactured components. The site was previously home to a nuclear reactor, closed in 1991, and has an existing local nuclear supply chain.
Stein said: “Trawsfynydd is a great first site for the [reactor]. Right now the jury’s out – there are a number of great sites around the country – but two of the three sites [under consideration] are in Wales.” He added: "With so-called brownfield sites, where there has been a nuclear reactor, we know the local population is happy, there is a skilled local population that used to run the plant, there’s a grid connection and the seismic condition of the site [is suitable]."
Rolls-Royce announced last year that it was working with a consortium of companies including Laing O’Rourke, Bam Nuttall and Atkins to develop small modular reactors (SMRs), with Laing O’Rourke telling Construction News that it could use its offsite manufacturing facility to produce components. Once operational, each SMR could generate 440MW of energy, enough to power Cardiff, Swansea and Newport combined, according to Rolls-Royce. The reactors have a target cost of £1.8bn each by the time five stations have been constructed, though the first will not be completed until at least 2029.
Wylfa in Anglesey has previously been identified by Rolls-Royce as another potential site for SMRs. However, in a statement, Horizon Nuclear, the Hitachi subsidiary still hoping to build two new reactors on the site, said there were “no plans” to deploy a miniature nuclear reactor at Wylfa Newydd.
Last month, Mott MacDonald nuclear global practice leader Mark Liddiard said that Moorside, where Toshiba cancelled a planned nuclear build last year, would be a suitable site for SMRs
