Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to the press release entitled Golden age of nuclear delivers UK-US deal on energy security, published on 15 September 2025, what estimate he has made of the proportion of components that will be produced in the UK.

The Government welcomes the recent announcements as part of the UK-US collaboration on advanced nuclear and opportunities it brings for energy security and industrial growth. The projects announced are privately led and individual supply-chain strategies are determined by the investors.

Our forthcoming framework will lay out a pathway for privately led advanced nuclear projects in the UK, aiming to unlock private sector investment and accelerate deployment with Great British Energy-Nuclear having a role to play in assessing proposals including scrutinising supply-chain strategies.

UKRI developed a methodology to assess how much could be delivered by the current UK supply-chain for a project, DESNZ are considering how this could be applied and adapted.
