Sellafield - Compliance inspection of LC7 and LC11 

Executive summary

Purpose of Intervention

This intervention, conducted at the Licensee’s Sellafield Limited (SL) Cumbria licensed site, was undertaken as part of the 2018/19 intervention plan and the Sellafield sub-division strategy.

Interventions Carried Out by ONR

I conducted a Licence Condition (LC) 7 (“Incidents on the site”) compliance inspection, which focused on the implementation of the licensee’s arrangements for the notification, recording, investigation and reporting of incidents, within the Sellafield Remediation Directorate and more specifically focussed on the First Generation Reprocessing Plant stack demolition organisation on Sellafield Ltd’s nuclear licensed site. This inspection was conducted to enable ONR to make a judgement as to the adequacy of the implementation of the licensee’s arrangements for compliance with the respective LC.

I conducted a Licence Condition (LC) 11 (“Emergency arrangements”) compliance inspection, which focused on the implementation of the licensee’s arrangements for dealing with any accident or emergency arising on the site and their effects, within the Sellafield Remediation Directorate and more specifically focussed on the Active Handling Facility operated by both the NNL and Sellafield organisations on Sellafield Ltd’s nuclear licensed site. This inspection was conducted to enable ONR to make a judgement as to the adequacy of the implementation of the licensee’s arrangements for compliance with the respective LC.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

No matters were identified as requiring immediate regulatory attention during the conduct of the compliance inspection.

I identified the following minor areas for improvement during the compliance inspection and these have been raised as Regulatory Issues which will be managed as part of normal regulatory business:

Sellafield Ltd should provide appropriate evidence that the requirements for training of incident control personnel stipulated by the site licensee have been met by all personnel assigned to these roles in the Active Handling Facility.

The emergency exercise plan for the Active Handling Facility should be supported by an appropriate justification which defines the appropriateness of the plan and links this to a wider strategy to ensure all incident responders are appropriately SQEP; this should include linking to lower level training / exercising activities as appropriate.

The Active Handling Facility should review plant labelling and ensure that all safety equipment and plant is appropriately labelled and that any inappropriate labelling is removed.

Conclusion of Intervention

No matters were identified as requiring immediate regulatory attention during either the routine meetings with key licensee personnel, or during the conduct of the LC 7 & LC 11 compliance inspections.

The LC 7 compliance inspection demonstrated that the licensee has adequately implemented the arrangements in place under LC 7. I therefore consider, noting the ONR guidance on inspection ratings, that an inspection rating of Green (no formal action required) is merited here.

The LC 11 compliance inspection demonstrated that the licensee has adequately implemented the arrangements in place under LC 11. I therefore consider, noting the ONR guidance on inspection ratings, that an inspection rating of Green (no formal action required) is merited here.
