Unannounced inspection of LC 11 and 26

Executive summary

Purpose of intervention

This intervention at the RRMPOL Nuclear Fuel Production Plant (NFPP) and Neptune Reactor at Raynesway was undertaken as part of the 2016/17 site inspection plan and strategy.

Interventions Carried Out by ONR

The purpose of this intervention was to: carry out an unannounced inspection of LC 11 and 26; carry out a compliance inspection of LC 15; and attend the level 3 regulatory interface forum.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

A planned unannounced inspection of control and supervision (LC 26) and the emergency organisation (LC11) was carried on the production plant. I judged that control and supervision was of a good standard and that emergency organisation personnel were either available or on call. No shortfalls were identified and no corrective action was required.

A LC 15 (Periodic review) compliance inspection was carried out and ONR examined the arrangements for the Neptune PRS which is currently being undertaken. The inspection team judged that the PRS process was adequate but found that the detailed knowledge of how to conduct the PRS resides with the individuals involved and is not fully described in a documented procedure. ONR placed an action on RRMPOL to review the adequacy of the LC 15 arrangements and ensure the level of detail is sufficient to ensure subsequent periodic reviews are conducted to a consistent standard.

At the regulatory interface forum I confirmed that ONR accepts the licensee's categorisation for the modification proposal to carry out refurbishment on the Neptune site and for the construction of a new facility on the NFPP site. In accordance with the licensee's arrangements RRMPOL can proceed with the work, ONR will apply enhanced implementation monitoring and control through the projects' progression.

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 number of opportunities for improvement were identified during the compliance inspection of LC15 and the licensee has taken an action to address these findings.
