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 Written Statement of 24 January 2025 on Plutonium Disposition Strategy, HCWS388, if he will publish the basis for the Nuclear Decommissioning Authority’s recommendation to immobilise the UK plutonium stockpile.

The Nuclear Decommissioning Authority (NDA) conducted substantial technical, deliverability and economic analysis to identify a preferred option for a long-term disposition solution, considering options for immobilisation and reuse of the material as fuel. It is not intended for the NDA analysis to be made publicly available due to commercial sensitivity and safeguarding national security.
