PARLIAMENTARY DEBATE
Small Modular Nuclear Reactor Power Station: Wylfa - 17 November 2025 (Commons/Commons Chamber)
Debate Detail
Nuclear energy provides the stable low-carbon baseload we need to keep the lights on and to support our economy. It is central to our clean power mission. That is why we have launched a new golden age of nuclear, committing £17 billion to the most ambitious programme of new nuclear for a generation. Our small modular reactor—SMR—programme, led by Great British Energy Nuclear, is an example of British innovation at its best. These mini reactors are smaller and quicker to build than traditional nuclear power stations, and we have been considering which is the best site to kick off the SMR programme now that we have reached that decision.
Last week, we announced that Wylfa on the north coast of Anglesey—Ynys Môn—is our chosen site for GBE Nuclear’s first SMR project. A written ministerial statement on the matter was made on Thursday. The initial project will see, subject to contracts, the construction of up to three Rolls-Royce SMR units. The site could host as many as eight, subject to future policy and funding decisions. That will deliver the largest industrial investment in north Wales for a generation. It will provide 3,000 good jobs on the site at peak construction. GBE Nuclear already looks forward to working with Welsh communities on the project, with work due to start on the site as early as next year.
We will be progressing the SMR project across this Parliament, working towards final investment decision. Meanwhile, large-scale nuclear power stations will also continue to make a vital contribution to our home-grown clean energy mix, complementing these SMRs. We will continue to act decisively, to invest ambitiously and to work with communities, investors and allies to deliver this golden age for new nuclear.
Last week’s announcement that nuclear power will return to Wylfa is hugely welcome. I am pleased that the Government have backed the site. As I have mentioned several times in this Chamber, Wylfa is recognised as the best site in Europe.
May I pay tribute to the teamwork over decades, by elected Members from all parties, campaigners, businesses and the local community, who have long fought for new nuclear at Wylfa. Ynys Môn has known nuclear for 65 years, with a strong local college and university ready to train a skilled workforce of the future.
To maximise the success of the project, the Government must work with the local authority on behalf of our community to deliver tangible economic and social benefits. That includes maximising opportunities in the local supply chain. The potential is clear, but the challenge is turning it into reality. After many false dawns and broken promises, my optimism is cautious. We know the cost of failure on Ynys Môn: when the Wylfa Newydd project collapsed, it robbed a generation of the opportunity to live and thrive in their community.
Recent data from the Nuclear Industry Association shows that nuclear jobs on Ynys Môn are at a record low. We cannot afford further setbacks. Clear timelines and transparent decisions are therefore essential. Can the Minister confirm when the Rolls-Royce contract will be signed, the general design assessment completed and the final investment decision made? As it stands, the SMR project is already four years behind the previous Horizon project at Wylfa. The project had a planning application and was approaching a final decision before it collapsed.
Funding the SMR project at Wylfa remains critical. Although the Government’s £2.5 billion for the SMR programme is welcome, most of the costs at Wylfa will currently be funded privately. Given the problems of the past, and that Wylfa will host a fleet of SMRs—these first-of-their-kind reactors—are the Government prepared to demonstrate their full commitment?
We cannot let this historic opportunity slip through our fingers yet again. This is a unique opportunity to create a project that will deliver for our language, our culture and our young people. I urge the Government to work with myself, key stakeholders and developers to provide the best project ever to deliver prosperity and energy security.
I join the hon. Lady in paying tribute to all those who have worked on this project over a great many years. There have been a lot of false starts and disappointments, but last week was a huge moment not just for realising the potential of the site with the next generation of nuclear, but for the UK to see SMRs actually move forward after years of talking, and, with that, the huge investment coming into the social and economic fabric of communities like hers.
The Prime Minister spoke last week about the investment—in colleges, for example—to ensure that we have the skilled workforce in the local area. Nuclear prides itself on creating many well-paid and sustainable jobs. Of course, the hon. Lady’s community has benefited in that way from previous generations of nuclear. We are determined to ensure that those economic and social benefits are felt by her constituents and for those right across the UK.
The Conservative position is that we need a lot more nuclear. We were the party that overturned the complete failure of the previous Labour Government to start any British nuclear plants, so I say this with some feeling. I have been told that there was just one nuclear welder left in the country when we started work on Hinkley Point C. We invested in the supply chain and in skills, which had completely withered under the previous Government. Now the most important thing is to keep building.
I personally signed off on a third large nuclear plant at Wylfa because it is our best site. It could host both large-scale nuclear and small modular reactors. By ruling out large-scale at Wylfa and ditching the 24 GW target, are the Government calling time on new large-scale nuclear? That is what it looks like to the rest of the country. It would be a huge mistake—the same mistake that Labour made last time it was in power. If we want cheap energy and growth in this country, we need to build, build, build when it comes to nuclear.
The Minister talked about power generation from SMRs in the 2030s, but industry is being told that it will be 2042 at the earliest. Who is right, and is that really the best the Government can do? We have plans to make nuclear building much cheaper. In fact, to cut environmental red tape, we tabled radical amendments to the Planning and Infrastructure Bill, but the Government voted against them. The nuclear regulatory taskforce will report soon, though; will the Government consider our proposals when it does? Lastly, does the Minister agree that it is fundamentally absurd for the Green party to talk about clean power while it has a policy of dismantling Britain’s nuclear power plants?
The right hon. Member says “build, build, build,” but all the Opposition did was consult, consult, consult. She talks about signing off new nuclear, but none of it has been built. It is easy to sign things off, but the previous Government committed no money—not a penny of funding. On one of the biggest days for our domestic nuclear industry in a very long time, it was remarkable to hear Opposition spokespeople last week talk down the sector. They talked big for 14 years, but built very little. Not a single new nuclear project was completed in their entire time in office, and that is because they did not put any funding into delivering it.
We have committed almost £20 billion of real money to build real projects, because we are ambitious about our nuclear future, about Sizewell C and about this SMR programme. We have not ruled out any future giga-scale projects, but our ambition is matched by funding to actually deliver them. Wylfa was the absolute best site on offer, which is why we chose it to host this most important, flagship project for the United Kingdom. We are delivering jobs and investment in Wales, and we are delivering the next generation of nuclear after many, many years of disappointment by the Conservatives.
Does the Minister agree that Scotland could have these jobs—that Dounreay, Torness in East Lothian, and Hunterston in the constituency of my hon. Friend the Member for Central Ayrshire (Alan Gemmell) could have these jobs—if it was not for the Dr Nos of the SNP and their outdated opposition to nuclear power?
We know that nuclear power stations across Scotland have delivered generations of well-paid, skilled and sustainable jobs. I recently met people in Torness who had started out as apprentices and who are still there, 20 or 30 years later, working in the nuclear industry. There will be jobs in Scotland in the supply chain for the SMR programme and Sizewell C, but it is a great shame that the Scottish National party is holding back the full potential of Scotland to be part of this nuclear story. I hope that the people of Scotland will vote for a different Government in May, so that we can get on with delivering the jobs and investment in communities right across Scotland.
The Liberal Democrats are pleased to see SMRs coming forward as part of a mix of cost-effective and safe decarbonised power generation, but will the Government please confirm that they will also maintain focus on boosting wind and solar power generation in order to bring down everyone’s energy bills? My hon. Friend the Member for Thornbury and Yate (Claire Young) has been working closely with constituents who will now be disappointed that the alternative site of Oldbury has not gone forward, so can the Minister clarify what the future is for that site?
The hon. Member is right to highlight Oldbury, which is a hugely important nuclear site that is owned by Great British Energy Nuclear. We continue to look at the future potential for Oldbury and other sites. This is not the limit of the Government’s ambition on nuclear; it is the next stage of that ambition. Wylfa was judged as the best possible site for the SMR programme and it is right that we put our flagship programme on the best possible site, but we are ambitious about the future of nuclear and Great British Energy Nuclear is looking at a range of sites across the UK—including both Oldbury and sites in Scotland—for potential future projects.
Our country’s energy needs will clearly only increase in the coming years, and we will be looking at the future of that energy mix, and the mix of renewables with nuclear. The Secretary of State has charged Great British Energy Nuclear to look at what more projects there will be. I take my hon. Friend’s point about a road map to give some certainty to that, and I am sure that the Minister for Science, Innovation, Research and Nuclear, Lord Vallance, will have heard that comment, as well as Great British Energy Nuclear, and I am sure they will work with her on that.
In terms of the overall timeline for the SMR programme, our ambition is that the SMRs will be online in the mid-2030s. There is obviously a significant amount of work to do on the site itself and on the designs, but we want to ensure that we are moving everything possible to get this done quickly. We have a first-mover advantage as a country if we can prove that this technology works, set about expanding it and look at the export market for it internationally.
As I said earlier, Great British Energy Nuclear’s ambition is that 70% of the supply chain products that will build these SMRs will be built in Britain. That is a hugely important investment right across our economy. Of course, 70% might not be the ceiling of our ambition, but this is an opportunity for communities and businesses to come forward and say, “We can help to build this innovative and hugely important part of our future energy mix, and we are really excited about the opportunities that it presents.”
Jobs will come from this project in Ynys Môn, but more jobs will come from the wider energy transition right across Wales, from our investment in transmission infrastructure to our investment in renewables projects, as well as in the Celtic sea and all the jobs that go with it. That will be delivered by this Government’s commitment to clean power—to delivering not just the energy system of the future, but the jobs that go with it. We will have an industrial strategy that creates jobs in Wales, after 14 years of a lack of industrial policy leading to job losses across the country. This is the beginning of great things for Wales; it is leading the way in this area, and with the expertise, skill and commitment that exists in Wales, it will do a fantastic job and make this country proud.
I am happy to come back to my hon. Friend on the timeline, but we have said throughout that we want to move as quickly as possible to make sure that the regulatory regime maintains the safety that the British public rightly expect, while also being flexible enough to ensure we take advantage of these opportunities when they come. We are working on that as quickly as possible.
My hon. Friend’s second point is also right. Investment in the UK in the clean power transition is hugely important. We have had more than £50 billion of private investment since we came to power last year. That is because of the certainty and the policy confidence that investors have in the UK. That would be put at risk by the policies of the Conservatives, Reform and others who talk about the future energy mix, but miss out the detail and put that investment at risk. That puts at risk jobs and investment in supply chains across the country, too. We are delivering the energy policy of the future for energy security, for climate leadership and for good jobs.
