Planned Site Inspection against Licence Conditions 25 and 26 on Operational Records and Supervision of Operations

Executive summary

Purpose 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 attended: a meeting with the Environment Agency (EA) and Berkeley staff on the treatment of intermediate level waste (ILW) at Berkeley; an emergency planning consultative committee meeting; and the site’s January stakeholder group meeting.

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

I reviewed Berkeley’s procedures for complying with LCs 25 and 26 and how they were implemented.  I concluded that Berkeley had adequate arrangements which were implemented appropriately in compliance with these LCs because:

Persons responsible for meeting the LCs were suitably qualified and experienced and knew what they needed to do for undertaking all operations that may affect safety;

Records were adequate for the work being undertaken now, but I noted the records may need to be modified when the site enters the Care and Maintenance (C&M) stage. Magnox Ltd is however considering this issue in preparation for the site C&M;

Records were adequately stored to protect these against identified hazards on site, including fire;

Control and supervision of operations affecting safety were current and addressed the licence requirements.

Preparations were underway for an off-site emergency demonstration exercise that is planned to take place later this year.

I note that Berkley’s early engagement with the ONR and EA has assisted timely regulation of progress made in relation to interim storage of Intermediate Level Waste on the site in a passively safe form in appropriate self-shielding containment.

Conclusion of Intervention

From the evidence sampled during this inspection and the discussions held with Berkley staff, I found that the operational records and control and supervision of operations were adequate, meeting the required safety standards. Other information supplied to me will help me to plan my interventions for assessing the safety and effectiveness of future work on site involving movement of radioactive material.
