Oldbury visit

Executive summary

Purpose of intervention

The intervention was to check Oldbury’s compliance with three licence conditions and to attend the joint Berkeley and Oldbury site stakeholder meeting, which occurs once a year.

Interventions Carried Out by ONR

I inspected Oldbury for compliance with the licence conditions on modifications or experiments to existing plant, operating rules and operating instructions.

Explanation of Judgement if Safety System Not Judged to be Adequate

A safety system inspection was not carried out during this intervention.

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

Oldbury demonstrated to me how the Magnox Ltd Decommissioning Proposal Approval Form was used to control modifications and experiments in a way that demonstrates compliance with the licence condition, environment legislation, conventional safety, and transport and security issues.  I also checked how operating rules and operating instructions were used to ensure defuelling of the reactors was undertaken safely and within the safety case parameters.

The Joint Berkeley and Oldbury Stakeholder Group meeting did not raise any questions or issues related to the work of ONR as presented in my Quarterly Report.

Oldbury shared with an ONR Civil Nuclear Security colleague and me how the site had dealt with some recent minor incidents affecting work on the site, and the plans being developed for management of the site once it is declared fuel free.

Conclusion of Intervention

Oldbury demonstrated to me that it is complying with its arrangements made under the licence conditions for modifications or experiments to existing plant, operating rules and operating instructions.
