Alternative Routes to Market for New Nuclear Projects

The Department for Energy Security and Net Zero is developing alternative routes to market for new nuclear projects, including advanced nuclear technologies, to diversify financing mechanisms beyond traditional approaches. This includes consultation on financial support for nuclear lifetime extensions and third-party liability frameworks for advanced reactor designs. The policy is active and aims to enable new nuclear deployment through flexible market access and investment structures.

When designating EN-7, the Government should publish a plan with its preferred level and mix of nuclear technologies, indicative deployment timelines, and the role of EN-6 sites potentially suitable for gigawatt-scale plants. Each part of this plan should explain the role of GBE-N in facilitating it. (Recommendation, Paragraph 21)

Some witnesses are concerned that the GDA has capacity constraints and is a lengthy and expensive process given that there are no site-specific guarantees afterwards. Whilst acknowledging the need for UK sovereignty over regulations, witnesses pointed out the considerable overlap of the technical approval process for new reactors between established nuclear nations.

Gigawatt-scale nuclear power plants require UK experience—of the supply chain, regulatory processes and the wider energy sector—to deliver projects efficiently. However, the UK may benefit in the future from multiple operators of small and advanced, nuclear power technologies as they have the potential to provide market competition, collaboration opportunities and prevent a groupthink mentality.
