Systems Based Inspection on Preparations for Care and Maintenance

Executive summary

Purpose of Intervention

This inspection of Magnox Ltd's Bradwell nuclear licensed site was conducted as part of a programme of planned interventions as outlined in the Bradwell Integrated Intervention Strategy (IIS) for 2017/18.

Interventions Carried Out by ONR

During this intervention, I undertook a System Based Inspection (SBI) on the preparations for entry to Care and Maintenance operations. This inspection was undertaken as part of the continuing programme of decommissioning aimed at the site entering care and maintenance operational status later next year.

The intervention was carried out against the requirements of LC's 10, 23, 24 27, 28 and 34; and ONR's published inspection guidance for these Licence Conditions.

I also undertook a walkdown of the site and held a meeting with the safety reps.

Explanation of Judgement if Safety System Not Judged to be Adequate

The conclusion of this intervention was that the arrangements for preparing the site for care and maintenance met the requirements in the safety case.

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

Based on my examination of a sample of the management arrangements at Bradwell site for nuclear matter are adequate for managing operations on the site. There is a clear management structure and process. The preparations for the entry to care and maintenance operations (C&M) are nearing completion and a sound process for managing the transition to C&M is in place Therefore we have rated compliance with LC's 10, 23, 24, 27, 28 and 34 as Green.

The inspection also included a meeting with the safety representatives and a discussion regarding a request for approval of a change to the emergency arrangements in support of a change from shift to day working.

Conclusion of Intervention

From the evidence gathered during this intervention, I concluded that there are no matters of nuclear safety concern. I have therefore rated the licensee's compliance with Licence Conditions 10, 23, 24, 27, 28 and 34 to be adequate (green).

One issue was raised on the Authorisation to Work (ATW) procedure where there had been a number of instances of excessive amounts of decommissioning work on a single form. I raised this at the close out meeting and will follow it up as part of routine regulatory business.
