Licence Condition 6 Compliance Inspection

Executive summary

Purpose of Intervention

This was a planned inspection of EDF Energy Nuclear Generation Ltd.’s (NGL’s) Hunterston B 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 Hunterston B Integrated Intervention Strategy (IIS) for 2018/19.

Interventions Carried Out by ONR

As part of this intervention I, the nominated site inspector carried out an unannounced inspection against:

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

I also held a number of routine meetings and received updates on the progress being made to close out regulatory issues previously raised.

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

Licence Condition 6 (Documents, records, authorities and certificates) - I inspected the station implementation of the fleet and site records management procedures.  I found the document centre personnel to have a good knowledge of the required procedures and evidence was provided to demonstrate that these procedures are being followed.  In a majority of cases new documents and records are retained in electronic format.   There is a need to review the site record retention schedule to ensure that it correctly identifies all records required to be retained under the site licence; this includes those records arising from corporate specifications and procedures where they are followed directly.

There have been recent improvements to the store where hard copies of records are held on-site.  Records stored off-site are being progressively returned to site and converted to and stored in electronic format.  The condition of records is inspected quarterly however some records are not inspected and should be subject to an appropriate condition monitoring regime.

From the sample of procedures and practices applied to records management at Hunterston B, I judged that the station is meeting relevant good practice.  There are some areas, identified above where station can improve its performance and a regulatory issue will be raised and agreed to address these matters.  I have therefore rated this inspection as Green, no formal action for LC 6.

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 Hunterston B Power Station as set out in the Integrated Intervention Strategy, which will continue as planned.
