Oldbury nuclear licensed site planned intervention inspections

Executive summary

Purpose of intervention

My intervention was held at Oldbury to undertake planned inspections of compliance with reporting incidents on the site and the use of duly authorised and other suitably qualified and experienced persons.  I also attended the Berkeley and Oldbury Joint Site Stakeholder’s Group meeting. These activities are part of ONR’s Decommissioning, Fuel and Waste intervention programme for Oldbury. 

Oldbury took the opportunity of me being on site to update me with progress on the demonstration that the site will be fuel free.

Interventions Carried Out by ONR

The reporting of incidents on the site and the use of duly authorised and other suitably qualified and experienced persons are required under the licence conditions attached to Oldbury’s nuclear site licence.  

Explanation of Judgement if Safety System Not Judged to be Adequate

This intervention did not include the inspection of a safety system.

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

We noted that the Magnox Ltd guidance on reporting incidents to ONR could result in under reporting in certain circumstances.  The guidance is undergoing review.  As such this was a useful time to provide feedback on our views on how Oldbury interpreted the current Magnox Ltd guidance, so that the new version of the guidance will address potential existing weaknesses.  We found that in some areas Oldbury demonstrated good practices and indicated other areas where improvements could be made.  As a result we judged Oldbury to be meeting the licence condition adequately.

I found that how Oldbury dealt with the issue of using duly authorised staff for certain posts and other suitably qualified and experienced persons in other posts to be adequate currently.  I pointed out that this needed to be maintained for all activities undertaken when programme staff came to site and when other changes were made to Oldbury’s management structure in the transition to decommissioning from defuelling.  Oldbury confirmed that this was being taken into account.

I noted the work and progress being made in shipping fuel from Oldbury and the work being undertaken to show that disused areas where fuel had been present and other areas where fuel might be stored were in fact fuel free.  This work did not rely on one set of data for the demonstration, which gave me confidence the case for the site being fuel free will be makeable.

Conclusion of Intervention

In the areas inspected, Oldbury demonstrated that the site was compliant with reporting incidents on the site and the use of duly authorised and other suitably qualified and experienced persons.
