Planned inspection at Urenco UK Limited, Capenhurst

Executive summary

Purpose of intervention

The Office for Nuclear Regulation (ONR) undertakes all regulatory interaction with the Capenhurst site against a strategy defined by the ONR Sellafield, Decommissioning, Fuels and Waste Programme. In accordance with that strategy, a Licence Condition (LC) compliance inspection on Capenhurst Nuclear Services (CNS) was undertaken, as planned.

The purpose of this intervention was to undertake a License Condition 28 (LC28) - Examination, Inspection, Maintenance and Testing (EIM&T), compliance inspection at CNS, tenants on the Urenco UK Ltd (UUK) nuclear licensed site. The inspection focused on legacy cylinder storage, ageing management arrangements, together with their implementation and plans for a new Legacy Cylinder Facility (LCF).

Interventions Carried Out by ONR

An ONR specialist mechanical engineering inspector, together with the nominated Site Inspector undertook a planned LC28 compliance inspection focusing on legacy cylinder storage, ageing management arrangements, together with their implementation and plans for a new LCF.  Through discussion with key personnel, plant inspection and examination of licensee documentation and records, we performed a LC28 EIM&T compliance inspection.

Explanation of Judgement if Safety System Not Judged to be Adequate

The LC28 EIM&T arrangements and their implementation were judged overall to be adequate.

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

The LC28 compliance inspection was performed in line with ONR's guidance, as described in ONR's technical inspection and assessment guides.  The ONR guidance can be found at wwww.onr.org.uk/operation/tech_insp_guides/index.htm).  The key findings against LC28 are recorded below:-

LC 28 (Examination, Inspection, Maintenance and Testing) - Rating - Green

From the areas sampled, the CNS LC28 EIM&T arrangements, together with their implementation were judged overall to be adequate. No significant shortfalls in the formal arrangements for compliance with LC28 were identified during the inspection.  Therefore, it is my opinion that, against compliance with Licence Condition 28, an IIS rating of Green (No Formal Action) is merited.

ONR confirmed appropriate arrangements had been established supporting the ongoing monitoring of legacy cylinders and noted the work underway to enhance ageing management arrangements.

During the inspection a number of improvement opportunities and minor observations were identified, which will now form part of future routine engagement.

Conclusion of Intervention

From the areas sampled during this inspection, I judge that there was sufficient evidence that UUK governance and CNS formal arrangements for compliance with Licence Condition 28 are being implemented adequately and effectively managed. Importantly, the conclusions and judgements are based not only on the documented evidence provided, but also the behaviours encountered during the inspection.

For this intervention, improvement opportunities and minor observations identified, will be progressed through routine follow up by the nominated site inspector with no matters identified requiring regulatory attention or action.
