Rolls Royce Marine Power Operations Limited - Level 3 Regulatory Interface Forum and LC 3 compliance inspection

Executive summary

Purpose of Intervention

This intervention at the RRMPOL Nuclear Fuel Production Plant (NFPP) and Neptune Reactor licensed sites at Raynesway; Derby was undertaken as part of the 2017/18 intervention plan and strategy.

Interventions Carried Out by ONR

The purpose of this intervention was to: hold update meetings with General Manager and Internal Regulator; review progress on ONR’s regulatory issues; attend the level 3 regulatory interface forum; and conduct an LC 3 compliance inspection.

Explanation of Judgement if Safety System Not Judged to be Adequate

A safety based inspection was not carried out

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

A planned compliance inspection of LC 3 (Control of property transactions) found RRMPOL has made and implemented adequate arrangements to control property transactions.  The arrangements show the licensee does not, nor intends to let any part of the licensed sites.  I sampled a number of areas and confirmed the licensee was in full control of the licenced site.  I judged compliance was adequate and no improvement action was required.

I attended the Level 3 regulatory interface forum where I agreed that ONR will accept the safety category 2 modification proposal forms (MPFs) for the implementation of the revised Nuclear Fuel Production Plant (NFPP) safety cases for information only allowing RRMPOL to proceed with the implementation of the cases in accordance with their flexible permissioning arrangements.  RRMPOL will implement the cases in mid-2017 but are currently identifying the optimum time to do this.

A progress meeting found that RRMPOL is effectively managing ONR’s regulatory issues and findings from inspections in the regulatory commitment tracker.  A number of actions are approaching or just beyond their due dates and after a busy period preparing to move into the new facility RRMPOL is now focussing on delivering these commitments.  I am satisfied with this approach and will continue to monitor progress.

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.
