Nuclear Regulation Bill

The Bill is pre-legislative: it has been announced but no draft text has been published. The policy framework is, however, well-developed. The Nuclear Regulatory Taskforce's final report 1 and summary 2 (24 November 2025) provide the intellectual basis; the call for evidence that fed the Taskforce closed in August 2025 3 following an earlier April 2025 Citizen Space round 4. 'Building our nuclear nation' 5 (with its accessible-webpage version 6) is the formal Government response, headlining streamlined approvals and proportionate, efficient delivery. In parallel, DESNZ is using non-legislative instruments to align the operational interface: the NDA-ONR and NDA-EA memoranda of understanding 78 published in March 2026; the consultation outcome on the Rolls-Royce SMR justification application (May 2026) 9; the SMR summary programme business case (April 2026) 10; the 'Advanced Nuclear Technologies' rebrand 11; and the independent 2026 review of the NDA 12. The ONR Post-Implementation Review of Part 3 of the Energy Act 2013 (October 2024) 13 is the principal regulator-architecture evidence base. Adjacent regulatory modernisation is already biting — SI 2025/1171 operationalising the excluded-disposal-site regime inserted by Energy Act 2023 s.304 came into force on 2 December 2025. On the planning side, EN-7 has run through two consultation rounds 1415 with a final NPS in train.

Three clusters dominate the last six months. First, the policy framing was completed: the Taskforce report 12 (November 2025), the Government Response 3 and parallel WMSs 45 (March 2026), and the King's Speech announcement 6 (13 May 2026). Second, parallel operational decisions: justification of the Rolls-Royce SMR design 7 (13 March 2026); the GE Vernova Hitachi SMR GDA Step 2 fundamental assessment 8 (December 2025); publication of the SMR programme business case 9 (April 2026); and the new NDA-ONR/NDA-EA MoUs 1011 (26 March 2026). Third, the institutional layer: the independent 2026 review of the NDA 12, the UKAEA 2026-2030 strategy 13, the CoRWM response to the Taskforce 14 (January 2026), and DESNZ correspondence with committee on the nuclear third-party liability insurance market dated 26 March 2026 15. The May 2026 consultation outcome on the Rolls-Royce SMR justification application 16 is the most recent procedural milestone, and a parliamentary question of 22 April 2026 17 flags continuing scrutiny of how the Government will implement the Review recommendations.

Three live questions will shape the Bill's eventual shape. First, regulator architecture: the central Taskforce framing of 'radical reset' 1 points to material changes to the ONR's remit and possibly to the EA's nuclear-environmental-permitting boundary; the 2024 ONR Post-Implementation Review 2 is the most likely starting point. Whether ONR is restructured, given new statutory duties to promote deployment alongside safety, or simply re-scoped, is the single biggest unresolved question. Second, process coordination: select-committee evidence on the EN-7 NPS 3 explicitly criticised the lack of a 'truly joined-up approach across planning, safety, and environmental regulation' — the Bill is the obvious vehicle to fix that joinery between Nuclear Installations Act 1965 licensing, Planning Act 2008 NSIP consent, and Justification Regulations decisions. Third, scope: the Bill's name speaks to civil nuclear generation, but the corpus shows live regulatory questions across waste (the SI 2025/1171 carve-out; the May 2024 radioactive-substances framework 4), decommissioning (the 2026 NDA review 5), advanced reactors 6, and fusion (the 2021-2024 fusion-regulation track 78). The forward calendar therefore turns on whether DESNZ introduces a tightly-scoped Bill addressing the ONR remit and licensing process, or a broader vehicle picking up the NDA review, fusion regulation, and NTPL insurance market issues raised in the March 2026 correspondence 9. Practitioners should also watch the EN-7 designation timeline 10, the next GDA steps 11, and any GBE-N commercial-pipeline updates.

Three uncertainties matter. (1) Draft Bill text and impact assessment are not yet available; legislative scope cannot be specified beyond the King's Speech framing. (2) The interaction with the existing planning-side reform (EN-7 1, select-committee critique 2) is unresolved — the Bill could either embed coordination duties statutorily or leave the joinery to soft instruments like the new MoUs 34. (3) Inferred from corpus gap: there is no Commons Library briefing on the Bill in this corpus (consistent with how recently it was announced), no published explanatory notes, and no published Government response on the nuclear third-party liability insurance market beyond the March 2026 DESNZ correspondence 5. The CoRWM response to the Taskforce 6 indicates active waste-side scrutiny but the corpus does not yet show industry, trade-union or NGO published positions on the Bill specifically.
