1 Conclusion Third Report - Nuclear energy in Wales Accepted

Broad consensus exists for new nuclear energy generation to achieve net zero and energy security.

While we have heard dividing evidence on the role that nuclear energy should play in achieving the UK’s net zero targets and ensuring domestic energy security, there is a broad consensus between the UK and Welsh Governments, and the majority of our witnesses, in favour of new nuclear energy generation.

Government response. The government maintains a positive dialogue with nuclear site owners and has established Great British Nuclear (GBN) to drive its ambition for up to 24GW of nuclear energy by 2050. This confirms the stated consensus on new nuclear energy generation.

2 Conclusion Third Report - Nuclear energy in Wales Accepted

Nuclear energy plays a strong role for net zero due to current renewable storage limitations.

The storage technology required for an entire electricity system run on renewable energy is not there yet. Therefore, on balance, we consider that nuclear energy has a strong role to play, as part of a mix of low carbon sources, in achieving net zero and energy security.

Government response. The government aligns with the committee's conclusion, detailing its ambition for up to 24GW of nuclear energy by 2050 and the establishment of Great British Nuclear (GBN) to drive the UK's new nuclear programme.

3 Conclusion Third Report - Nuclear energy in Wales Not Addressed

Uncertainty and raised expectations for new nuclear build at Wylfa concern the local community.

The previous attempt to bring a new nuclear project to Wylfa by Hitachi has left scars on the local community. We are concerned that expectations are being raised again on Ynys Môn and question how long the uncertainty can continue about whether or not a new nuclear build will be …

Government response. The government outlines its long-term nuclear ambition and plans to develop a new National Policy Statement and consult on siting policy. However, it explicitly states that no decisions have been made on specific sites or technologies, which does not address …

4 Recommendation Third Report - Nuclear energy in Wales Rejected

Encourage Hitachi to sell Wylfa Newydd site or join a consortium for future nuclear development.

Given that the land at Wylfa Newydd is owned by Hitachi, it is unclear what the current state of play is at the site. If there is to be new nuclear at Wylfa, the issue of ownership of the land needs to be addressed. We reiterate a recommendation of our …

Government response. The government rejects the specific recommendation to encourage Hitachi to sell or join a consortium, stating that any decision to sell the Wylfa Newydd site is a commercial one for Hitachi. They confirm ongoing dialogue with site owners and that …

5 Conclusion Third Report - Nuclear energy in Wales Deferred

Wylfa is a prime site and should host the next gigawatt-scale nuclear plant.

We have heard from a wide range of industry representatives that Wylfa is one of the best sites for nuclear development and it is difficult to see how the UK Government can deliver its nuclear ambitions without taking forward a project at Wylfa. We consider that Wylfa should be the …

Government response. The government acknowledges the desire for a settled policy but states no decisions have been taken on which sites future projects will proceed with. It will develop a new National Policy Statement and consult later this year on future nuclear …
Wales Office
6 Recommendation Third Report - Nuclear energy in Wales Accepted in Part

Pursue new gigawatt-scale nuclear plants alongside existing Small Modular Reactor policy.

While successfully developing a Small Modular Reactor (SMR) would present a huge opportunity for the UK, the technology is still in development phase. If the UK Government is serious about nuclear energy now it needs to pursue new gigawatt- scale plants alongside its policy on SMRs.

Government response. The government acknowledges the recommendation to pursue gigawatt-scale plants alongside SMRs, stating that while Great British Nuclear (GBN) will initially focus on SMRs, it will also support the government's consideration of further large Gigawatt-scale projects.

7 Recommendation Third Report - Nuclear energy in Wales Deferred

Include Trawsfynydd site as a potential SMR host in the Nuclear National Policy Statement.

The UK Government, and Great British Nuclear, should continue to engage with Cwmni Egino on its ambition for Trawsfynydd to become the first site to host Small Modular Reactors (SMRs) in the UK. We urge the Government to include the Trawsfynydd site in the new Nuclear National Policy Statement as …

Government response. The government states it will continue to engage with Cwmni Egino and will develop a new Nuclear National Policy Statement (NPS) to set out planning policy beyond 2025. It will consult later this year on siting policy for new nuclear …

8 Conclusion Third Report - Nuclear energy in Wales Acknowledged

Financing new nuclear projects at Wylfa faces ongoing challenges despite the RAB model.

The introduction of the Regulated Asset Base (RAB) model is welcomed as a better alternative to the Contracts for Difference (CfD) scheme for nuclear developments. However, financing new nuclear projects is not straightforward and there will still be challenges under the RAB model. For a development to progress at Wylfa, …

Government response. The government acknowledges the complexities of financing nuclear projects under the RAB model and reiterates its belief that the model encourages private investment while protecting consumers. They outline existing mechanisms like value for money assessments, the Nuclear Energy (Financing) Act …

9 Recommendation Third Report - Nuclear energy in Wales Accepted

Explain mechanisms for monitoring and reporting consumer risk during Sizewell C construction.

We recognise the high cost of construction of nuclear energy plants and the large upfront investment needed to get a project to final investment decision. We hope that the Regulated Asset Base (RAB) model will help overcome these investment challenges. However, there are valid concerns about the risk to consumers, …

Government response. The government states that existing legislation (Nuclear Energy (Financing) Act 2022) and current processes, including HMT Green Book approvals and Major Project Review Group approvals, ensure consumer interests are considered and projects are monitored. Ofgem, as the economic regulator, will …
