Executive summary

Purpose of intervention

This intervention at the Devonport Royal Dockyard Limited Licensed Site was undertaken as part of the 2015/16 intervention plan and Propulsion sub-programme strategy.

Interventions Carried Out by ONR

The interventions during this visit were: attendance at a meeting to update ONR with progress on 9 Dock and VDMP PSC 290 safety case development; discussions on progress with meeting the requirements of improvement notice I/2014/ONR/DMM/001; facility walk-down of the low level refuelling facility and the nuclear equipment maintenance & storage facility, attendance at the annual review of safety; and to undertake an LC 17 compliance inspection.

Explanation of Judgement if Safety System Not Judged to be Adequate

A system based inspection was not carried out.

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

The 9 Dock Plant Manager reported that no nuclear or conventional safety significant events have occurred on 9 Dock which require immediate regulatory attention.  I concurred with his view.

The Managing Director and 9 Dock Plant Manager accompanied ONR’s Superintending Inspector on a walk-down of the low level refuelling facility and the nuclear equipment maintenance & storage facility; general conditions observed in both areas was of a good standard and equipment appeared to be adequately maintained.

The licensee’s process management, process mapping and corrective action management arrangements were examined in an LC 17 – management systems compliance inspection.  In response to an issue raised during a previous LC 17 inspection DRDL has developed and implemented a process governance policy and I consider the issue has been satisfactorily resolved.  I judged the elements of the management system examined during the inspection to be adequate.

Conclusion of Intervention

No shortfalls or issues were found which adversely affected nuclear safety or were judged to be of such regulatory concern as to require immediate action.  No regulatory issues were raised.
