Special Nuclear Materials Operating Unit (SNM OU) Facilities - LC17 compliance inspection

Executive summary

Purpose of Intervention

The Office for Nuclear Regulation (ONR) undertakes all regulatory interaction with the Sellafield Site licensee (Sellafield Limited) (SL) against a strategy defined by the ONR Sellafield, Decommissioning, Fuel and Waste (SDFW) Division. In accordance with that strategy, a Licence Condition (LC) compliance inspections of the Special Nuclear Materials Operating Unit (SNM OU) was carried out, as planned in December 2018.

The purpose of this planned inspection was for ONR to determine the adequacy of implementation of the licensee’s formal arrangements for compliance with LC17 (Management Systems). For the inspection, I focused on the evidence for compliance within the Special Nuclear Material South (SNM (S)) facility.

Interventions Carried Out by ONR

On 5 December 2018, I, the site inspector for the SNM OU, accompanied by an ONR Conventional Health and Safety inspector undertook a planned LC17 Licence Condition inspection within the SNM (OU). The SNM OU SL Nuclear Independent Oversight (NIO) representative participated in the inspection also.

The inspection comprised discussions with SL personnel, and reviews of SL records, documents and processes.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable; this was not a safety system based inspection.

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

The inspection targeted the management system arrangements at the local Operating Unit level and how they are derived from the Sellafield Corporate arrangements for Maintenance activities in the SNM (S) facility.

Sellafield presented an overview of their Maintenance management document hierarchy and could clearly explain how the existing key policies, processes and procedures align to corporate management systems underpinning them.

During the inspection I sampled several Sellafield Ltd Practice (SLP) documents such as procurement of supplies and the policy for management of assets. Overall, I consider that Sellafield SNM (S) has adequately implemented its arrangements for compliance with LC17.  Indeed, implementation is good in several areas, for example there is a good understanding and management of obsolescence.

There were no significant findings identified during my inspection, and I have not raised any associated Regulatory Issues.

I am of the opinion that SL, as the licensee, has adequately implemented its arrangements for compliance with the Licensee’s Conditions LC17.

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

Conclusion of Intervention

From the evidence gathered during this intervention, I consider that the licensee is compliant with its legal duties under LC17 and therefore, it is my opinion that an inspection rating of Green (no formal action) is merited.

My findings were shared with and accepted by the licensee as part of normal inspection feedback. I have not raised any Regulatory Issues as a result of this inspection.
