Berkeley Nuclear Licensed Site Planned Inspection against Licence Conditions 16, 22 and 26 on Operational Records and Control and Supervision of Operations

Executive summary

Purpose of intervention

This report describes an inspection of Magnox Ltd's Bradwell licensed site, undertaken as part of a series of routine interventions set out in the Integrated Intervention Strategy document.

Interventions Carried Out by ONR

During the intervention I carried out an unannounced compliance inspection on licence condition (LC) 2 - Marking of the Site Boundary.

I attended a number of meetings that provided progress updates and opportunity to influence the work programmes to decommission the site and to transition it into its care and maintenance phase.

Explanation of Judgement if Safety System Not Judged to be Adequate

This intervention did not include a safety system based inspection.

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

I found evidence that the site arrangements for compliance with the requirements of LC 2 are adequate.

The site has adequate arrangements to prevent unauthorised persons from entering the site.  The site was not fully compliant with the requirement to mark the boundary of the licensed site. Immediate corrective action was taken and I confirmed that the boundaries were adequately marked before I left the site.

Conclusion of Intervention

This record is of my visit to Magnox Ltd’s Berkeley nuclear licensed site as part of ONR’s compliance inspection plan for the site. 

Interventions Carried Out by ONR

During the intervention I carried out compliance inspections on licence conditions (LC):

I also discussed recent incidents that had occurred at Berkeley and held a meeting Berkeley on the preparations for the level 1 demonstration exercise that is due to take place on 30 September 2015.

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

My inspection of the site plan and schedule for Berkeley found them to be up-to-date.  There were some minor changes needed so that the plan and schedule were completely accurate, but the demonstration of compliance was adequate.  I felt that Berkeley demonstrated that it met LC22 requirements for modifications on existing plant when compared with ONR guidance.  I discussed control and supervision of operations with some of the Berkeley managers working on intermediate level waste retrieval from the silo and vaults preparations.  They convinced me through evidence provided that they understood their duties in relation to those described in the ONR inspection guidance for LC26.  They had also developed a useful way of presenting the work and associated hazards on a white board plan of the areas, which was updated during the daily meeting with contractors before work begins.

Berkeley reported an incident where it appeared that a decommissioning contract had been cancelled before due process had been followed. I discussed this at some length with Berkeley managers and Magnox Ltd and concluded that there had been misunderstandings between parties and the report to ONR may have been unnecessary.

I undertook an unannounced site incident reporting inspection choosing a report on emergency arrangements in the fuel element debris removal control cabin.  After an inspection of the area and discussion with the site managers responsible, I concluded and the site agreed that the incident should be reported to ONR officially.  The Site Director initially classed the event as not needing to be reported to ONR.

Conclusion of Intervention

My inspection indicated that Berkeley had met the requirements of LCs 16, 22 and 26 at the time of the inspection in the areas inspected. 

Berkeley may not always err on the side of caution when considering incident reporting requirements.  The management are aware of my concern and are actively correcting the situation.
