RRMPOL planned inspection

Executive summary

Purpose of intervention

This intervention at the RRMPOL Nuclear Fuel Production Plant Raynesway was undertaken as part of the 2015/16 intervention plan and propulsion sub-programme strategy.

Interventions Carried Out by ONR

The purpose of this intervention was to observe an internal emergency exercise of the new Bronze Command Facility and confirm that ONR is content for it to be used for the LC 11 emergency arrangements, to carry out an LC 26 control and supervision compliance inspection and to attend update meetings.

Explanation of Judgement if Safety System Not Judged to be Adequate

A systems based inspection was not carried out

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

I judged that an internal emergency exercise of the new Bronze Command emergency facility successfully demonstrated that emergency personnel were familiar with the new facility and that it was fit for purpose.  It is a new facility and represents a substantial improvement in the sites emergency response capability.  I advised site that, provided the change is suitably managed, I am content for the new facility to be used.

An LC 26 compliance inspection was carried out to assess the adequacy of control and supervision.  The inspection concluded that a sufficient number Suitably Qualified and Experienced Persons (SQEPs) have been appointed to control and supervise operations which may affect safety.  The individuals appointed were knowledgeable of their roles and responsibilities.  The LC 26 compliance arrangements did not adequately describe the control and supervision process in use and RRMPOL is taking action to address the shortfalls in the procedure.  Compliance with LC 26 (Control and Supervision) was judged to be adequate.

In February the licensee notified ONR of an incident which involved spurious operation of a protection system on the Neptune Low Energy Reactor.  A thorough investigation of the event has been carried out by Site personnel.  A safety justification has been produced demonstrating that nuclear safety is not compromised by continued operations, and is under internal review and will be approved by RRMPOL in due course.  I am content that RRMPOL has taken appropriate action to justify safe continued operation.

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.  A regulatory issue has been raised to address shortfalls in the LC 26 procedures.
