Executive summary
Purpose of Intervention
This was a planned unannounced inspection of EDF Energy Nuclear Generation Ltd.’s (NGL’s) Heysham 1 Power Station, undertaken as part of the planned intervention strategy for the Operating Facilities Division (OFD) of the Office for Nuclear Regulation (ONR).
The work was carried out in accord with the planned inspection programme contained in the Heysham 1 Integrated Intervention Strategy (IIS) for 2019/20.
Interventions Carried Out by ONR
As part of this intervention I, the nominated site inspector carried out an unannounced inspection against:
- Licence condition (LC) 7 – Incidents on the site.
The purpose of LC7 is to ensure that incidents on the site are notified, recorded, investigated and reported by 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
No system based inspection was undertaken hence, this is not applicable for this intervention.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
The inspection sampled the adequacy of EDF arrangements in the areas of event screening, categorisation, reporting and investigation and I found that these correctly corresponded with the requirements for compliance with LC7.
The inspection also sampled the implementation of EDF arrangements by inspecting a daily event screening meeting, a corrective action review board and an operational learning group meeting. Overall I judged that EDF adequately demonstrate compliance with the requirements of LC7 and therefore rated this inspection as Green, no formal action.
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 at Heysham 1 Power Station as set out in the Integrated Intervention Strategy, which will continue as planned.
