Chapelcross - Compliance inspections

Executive summary

Purpose of Intervention

This inspection was one of a programme of planned inspections for 2018/19 carried out at Chapelcross licensed nuclear site to confirm that the licensee, Magnox Ltd, is complying with its statutory obligations.

Interventions Carried Out by ONR

The inspections undertaken were of the arrangements made under LC2 (Marking the Site Boundary); LC19 (Construction or installation of new plant); LC20 (Modification to design of plant under construction); and LC21 (Commissioning).  Other activities included reviewing extant regulatory Issues and a meeting with the Site’s Safety Representatives.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

During my inspections I did not identify any safety significant matters requiring formal action from the Licensee. However, I did make some observations which I conveyed to site personnel following the inspection.  These are summarised below.

Site should make sure there is a clear link in the arrangements made for LC 2 in MCP-001 to where the maintenance requirements are captured in the site security maintenance schedule.

Site and Magnox Ltd corporate centre need to ensure that there is sufficient SQEP resource available on the Magnox Intelligent Customer Database.

Site and the Magnox Ltd corporate centre need to ensure that the responsibility for signing off Lifetime Quality Records (LTQRs) is included in the broad job role for Quality Engineers, or that responsibility captured elsewhere in their arrangements.

Site should review its approach for tracking actions that are generated by commissioning reports, as I consider that the absence of a unique identifier for each may lead to some actions being overlooked and not properly closed out.

Conclusion of Intervention

I considered that overall the arrangements made under LC 2, 19, 20 and 21 that were inspected were adequate and that they were being adequately implemented.
