Simplify the nuclear regulatory landscape by consolidating nuclear regulatory functions

Simplify nuclear regulatory landscape

Full Recommendation Text

There should be a commitment, so far as possible, to only have one regulator per hazard type or regulatory function.

  • Merge DNSR and ONR, generating a specific defence enclave.
  • Consideration should be given to transferring other regulatory responsibilities for duplicative entities into a single regulator, for example regulation of radioactive substances or nuclear security.
  • The ONR should be given concurrent vires for radiological substances as the EA.

Government Response: ONR-DNSR merger confirmed

The Government will consolidate the nuclear regulatory landscape by merging ONR and DNSR, directly following the Taskforce recommendation. Initial changes will be implemented by Autumn 2026 with full merger completed by the end of 2028. The Government will also strengthen collaboration between the Environment Agency and ONR. This is a significant structural reform that addresses the fragmentation the Taskforce identified, though the full merger timeline extends beyond the original March 2026 target.
