EDF Energy Nuclear Generation - Corporate Inspection of LC13

Executive summary

Purpose of intervention

This was a planned inspection of EDF Energy Nuclear Generation Ltd. (NGL)’s Corporate Arrangements for its Nuclear Safety Committee Licence Condition 13 (LC13).

Interventions Carried Out by ONR

We carried out a planned compliance inspection against LC13 ‘Nuclear Safety Committee’.  The inspection focussed on inspection of the company’s arrangements; observation of an NSC meeting; discussions with the Chair and former Chair of the Committee and a Group Head from NGL’s Independent Nuclear Assurance function. We also interviewed three independent members of the Committee.

The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.

Explanation of Judgement if Safety System Not Judged to be Adequate

There was no safety system inspection carried out during this intervention.

Key Findings, Inspector's Opinions and Reasons for Judgements Made

From the range of discussions; observations and documents sampled we are satisfied that NGL’s NSC arrangements are being complied with. The arrangements required some updating. Whilst meeting the requirements of LC13 we considered the NSC is not necessarily being used as effectively as it could be and, in effect, this represents a ‘missed opportunity’ for the Licensee. There are opportunities to improve the conduct of NSC meetings and for provision of advice to the Licensee. Many improvements have already been identified by NGL which are supported by ONR. We recommend a further review of progress in approximately 12 months’ time.

Conclusion of Intervention

We were satisfied from the activities sampled that NGL’s arrangements for its NSC were adequate but there were a number of opportunities for improvement. Many of these had been already been recognised by the Licensee and were being effected by the NSC’s new Chair and are supported by ONR.


Some specific recommendations have been made with regard to review and updating of the arrangements; ensuring timely submissions to the NSC on the range of matters included in its indicative list of submissions; consideration of a proportionate set of metrics to help track NSC business and aid reporting to the Board and a recommendation to review progress in approximately one year’s time.
