Hinkley Point B - Planned compliance inspections

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake licence condition (LC) compliance inspections of EDF Energy Nuclear Generation Ltd.’s (NGL’s) Hinkley Point B Power Station. This was undertaken as part of the planned intervention strategy for the Operating Facilities Division (OFD) of the Office for Nuclear Regulation (ONR).

The intervention was carried out by the nominated site inspector.

Interventions Carried Out by ONR

I, the nominated site inspector performed an inspection to evaluate NGL’s compliance with the following nuclear site licence conditions (LCs), which are applicable provisions of the Energy Act 2013:

Whilst on site, I also undertook the following engagement activities with the licensee;

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

Not applicable – no system based inspections were completed during this intervention.

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

For LC7 I sampled the licensee’s arrangements for screening of events, the reporting and notification of events to ONR, the sentencing of events to ensure an appropriate level of investigation and the quality of investigations. I noted that a number of follow up reports for events that had been formally notified to ONR were overdue. A few minor observations were fed back to the licensee to consider, a  regulatory  issue was raised regarding the timely provision of follow up reports to ONR. Overall I am satisfied that the licensee arrangements and their implementation in compliance with LC7 are suitable and sufficient and that an IIS rating of green against LC7 is merited.

For LC36 I sampled the licensee’s arrangements for developing and maintaining the baseline as well as the effectiveness of the vulnerability analysis for the organisation. I also sampled some examples of change assessments and the control of their implementation. I noted that whilst the changes sampled appeared to be well controlled, there was a lack of clarity over which actions were required to be completed before a change was implemented. A few minor observations were fed back to the licensee to consider, a  regulatory  issue was raised regarding the identification and recording of actions required to address risks before a change is implemented. Overall I am satisfied that the licensee arrangements and their implementation in compliance with LC36 are suitable and sufficient and that an IIS rating of green against LC36 is merited.

Conclusion of Intervention

There were no findings from this inspection that could significantly undermine nuclear safety.  At present, no additional regulatory action is needed over and above the planned interventions of Hinkley Point B power station as set out in the IIS, which will continue as planned.
