Small Modular Nuclear Reactor Power Station: Wylfa

Llinos Medi Excerpts

Monday 17th November 2025 Commons Chamber

[Llinos Medi (Ynys Môn) (PC)]

(Urgent Question): To ask the Secretary of State for Energy Security and Net Zero if he will make a statement on the development of the UK’s first small modular nuclear reactor power station at Wylfa.

[The Minister for Energy (Michael Shanks)]

I welcome the hon. Lady’s commitment to securing a new nuclear project in her constituency. She and I have had a number of discussions about nuclear power and other energy projects.

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.

Diolch yn fawr, Llefarydd, for granting the urgent question.

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.

[Michael Shanks]

The hon. Lady is right that the community in Ynys Môn faced a number of false starts under the previous Government. This is an historic opportunity—a huge moment—as the project moves forward with tangible timelines in place and the £2.5 billion that she mentioned. Rolls-Royce is taking forward three SMRs initially, but there is the potential for more in the future. People will start to see jobs soon. We expect that there will be work on the site as early as next year, including 3,000 jobs when the construction phase is at its peak.

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.
