PARLIAMENTARY WRITTEN QUESTION
(29 January 2026)

To ask the Secretary of State for Energy Security and Net Zero, what recent comparative assessment he has made of the technical and strategic suitability of the Wylfa site for (a) a gigawatt-scale nuclear reactor and (b) Small Modular Reactors.

Asked by:
Claire Young (Liberal Democrat)

In November 2025, following careful deliberation, the Government announced that Wylfa will host Great British Energy-Nuclear (GBE-N) first Small Modular Reactor (SMR) project. Wylfa has the potential to accommodate more SMR units than other potential sites.

To pursue the option of further potential large-scale nuclear, the government has tasked GBE-N with identifying other suitable sites that could potentially host such a project. GBE-N will report back by Autumn 2026 on potential sites to inform future decisions in the next Spending Review and beyond.
