Delivering nuclear power

Status: Closed Opened: 19 Jul 2022 Closed: 28 May 2024 25 recommendations 38 conclusions 1 report

Due to rising fuel prices, securing the UK’s energy supply is currently a top priority for the Government and is of great interest to the public. The Government’s Energy Security Strategy , published in April 2022, emphasised that nuclear power would play a key part in supplying the UK with baseload electricity, however there is …

1 Conclusion Eighth Report - Delivering nuclear power Deferred

Life extensions for EDF reactors reasonable if deemed safely operational by regulator

We conclude that it is reasonable for EDF to seek life extensions to extend their contribution to the grid if, and only if, the Office for Nuclear Regulation’s judgement is that they can be safely operational as is currently the case.

Government response. The government welcomed EDF's decision to extend Heysham 1 and Hartlepool until March 2026 but stated that future lifetime extensions are decisions for the operator and the independent nuclear regulator based on safety and commercial considerations.

2 Recommendation Eighth Report - Delivering nuclear power Deferred

Spell out contribution of reactor life extensions to 24 GW nuclear target in Strategic Plan

The new Nuclear Strategic Plan, that we recommend, must spell out how the current reactor fleet, through life extensions, will contribute to the Government’s ambition of 24 GW from nuclear by 2050.

Government response. The government welcomed EDF's decision to extend two nuclear stations until March 2026, noting that lifetime extensions are decisions for the operator and regulator. It states it is not in a position to detail EDF's future plans for life extensions …

37 Recommendation Eighth Report - Delivering nuclear power Deferred

Apply consistent pay flexibilities across public sector research bodies, maintaining financial discipline through budgets.

In line with Sir Paul Nurse’s recommendations for greater flexibility on pay with conditions for Public Sector Research Establishments, we recommend that a consistent set of pay flexibilities should be applied to public bodies in the sector with financial discipline applied through the overall budgets for bodies. (Paragraph 185) Financing

Government response. The government stated that the recommendation regarding pay flexibilities was beyond the remit of the responding skills team, providing no substantive response.

43 Recommendation Eighth Report - Delivering nuclear power Deferred

Publish Sizewell C RAB model savings calculations and Heads of Terms for funding structure clarity.

The Government should publish details of how the estimated savings from using the RAB model for funding Sizewell C were calculated, and provide clarity for the funding structure, by publishing the Heads of Terms for the agreed RAB funding model for that project.

Government response. The government referred to an Impact Assessment for illustrative RAB model savings for a generic plant but stated that specific Sizewell C cost details and Heads of Terms are commercially sensitive and cannot be disclosed at this time.

45 Recommendation Eighth Report - Delivering nuclear power Deferred

Communicate a clear financial model for initial SMR deployment, as CfD is unsuitable.

If a single supplier of SMRs were to be available, either through Government choice or following the Generic Design Assessment process, the CfD auction model will not be suitable. As part of a clear and specific strategy for SMRs, the Government should come to a view quickly on what financial …

Government response. The government stated that Great British Nuclear's technology selection process is not limited to a single supplier and that the Regulated Asset Base (RAB) model is a promising option for SMRs. A consultation on "alternative routes to market," including the …

52 Conclusion Eighth Report - Delivering nuclear power Deferred

Reflect on GDA lessons for SMR efficiency and safety cases following first completion

Whilst the ONR has recently adapted the GDA to be more suitable for small modular reactor (SMR) technologies, to date no SMR design has completed the entire three step process. The ONR should reflect, both during and after the first SMR has completed the GDA, on the lessons to be …

Government response. The government deflected the recommendation, stating that as an independent organisation, it is for the ONR and other regulators to comment on their processes for lessons learned, and the government should not comment.
