Explanation of Judgement if Safety System Not Judged to be Adequate

No system based inspection undertaken hence, not applicable.

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

We evaluated compliance against the following site licence conditions during our themed intervention:

I requested progress updates on a number of regulatory issues and engaged with the senior management team on forthcoming improvement initiatives and operational focus.  No significant nuclear safety concerns were raised during these discussions.

The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.

Conclusion of Intervention

The themed inspection examined compliance against LC12, LC23, LC24, LC25, LC26, LC27, LC28 and MHSW Reg 5. Overall, based on the evidence sampled, inspectors judged that legal requirements were met.  We observed a number of work activities including the pre-job briefs and setting to work activities.  In all cases the level of control and supervision was commensurate with the safety significance of the task. One minor compliance shortfall was identified relating to adequacy of assumptions made during the work planning process associated with availability of SQEP capability to deliver maintenance activities according to schedule. A level 4 regulatory issue was raised in order to monitor the agreed remedial action.
