Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, to what extent (a) uranium fuel used at Sizewell B and (b) Britain’s nuclear energy supply chain relies on imports from (i) Rosatom and (ii) its subsidiaries; and what steps he is taking to ensure that sanctions placed on Rosatom are enforced in relation to UK nuclear power stations.

The procurement of nuclear fuel, including uranium and enrichment services, is a commercial matter for reactor operators. The Government works closely with these operators to ensure a secure and resilient supply for the UK fleet but does not routinely collect information relating to any fuel contracts held by UK operators. This information is commercially sensitive, and disclosure would be at the discretion of the operator.

The Government is committed to removing Russian nuclear fuel from UK supply chains by the end of 2028. All current and future reactor operators must comply with UK legal obligations, including any sanctions or trade measures in place against Russia.
