Magnox Ltd - Oldbury and Berkeley Power Stations compliance inspection

Executive summary

Purpose of Intervention

I undertook this intervention to examine Magnox Ltd's compliance with a number of Licence Conditions (LCs) at Berkeley and Oldbury power stations. This was a planned intervention as detailed in ONR's intervention plans for the Berkeley and Oldbury sites, and in support of ONR's Decommissioning Fuel and Waste sub-division strategy.

Interventions Carried Out by ONR

I inspected LC 6: Documents, records, authorities and certificates, and LC 17: Management systems.

Explanation of Judgement if Safety System Not Judged to be Adequate

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

Based upon the arrangements sampled I found that Magnox Ltd, at the Berkeley and Oldbury sites, has established and implemented management systems which give due priority to safety. Within these, I found that it has made and implemented adequate quality management arrangements in respect of safety. The management system also makes reference to internationally recognised good practices for management systems, and has a clear, albeit changing, structure. Process owners were appointed and it was clear which documents are put in place to achieve LC compliance. I found that a top-level management system requirement for a Company Safety Improvement Plan could be traced to the performance management objectives of individuals working at site-level.

I found that Magnox Ltd, at the Oldbury site, has made and implemented adequate arrangements for the retention of documents and records required by the Licence Conditions, and that the facilities where the records sampled were stored are suitable. At the Berkeley site I found that in a number of cases the location and ownership of records required for compliance with the Licence Conditions is unclear as the record schedule is incomplete. In addition a large number of records are not stored adequately.

I did not identify any significant shortfalls with the management system arrangements or their implementation during this inspection (other than the implementation of record management arrangements at the Berkeley site examined under LC 6) and it is therefore my judgement that Magnox Ltd has adequately demonstrated that it is compliant with LC 17: Management systems at the Berkeley and Oldbury sites. I also judge that Magnox Ltd has adequately demonstrated it is complaint with LC 6: Documents, records, authorities, and certificates at the Oldbury site.

I identified a number of shortfalls, when compared to relevant good practice, with the arrangements for records management at the Berkeley site and I judge that improvements are required for Magnox Ltd to adequately demonstrate compliance with LC 6 at this site.

Conclusion of Intervention

I have discussed the inspection findings with the Berkeley site leadership team and will be following up the site's progress in addressing these shortfalls during routine planned engagement.
