Sellafield - Remediation Value Stream - compliance inspection of LC 6 and 9

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 two Licence Condition (LC) compliance inspections.

A LC 6 (“Documents, records, authorities and certificates”) compliance inspection, which focused on the implementation of the licensee’s arrangements to ensure that adequate records are made and held for a suitable period to demonstrate compliance with the licence conditions attached to the site. The inspection was undertaken within the Sellafield Remediation value stream and more specifically focussed on the demolition works for the Pile 1 blower house on Sellafield Ltd’s nuclear licensed site.

A LC 9 (“Instructions to persons on the site”) compliance inspection, which focused on the implementation of the licensee’s arrangements to ensure that every person authorised to be on the site receives adequate instruction as regards the risks and hazards associated with the plant and its operation, the precautions to be observed and the action to be taken in the event of an accident or emergency on the site. This inspection was also undertaken within the Sellafield Remediation value stream and specifically the demolition works for the Pile 1 blower house 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 LCs.

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 whilst conducting the compliance inspection on both LC 6 and LC 9.

LC 6 Inspection

The licensee was unable to provide a records schedule to demonstrate compliance with Sellafield site arrangements.  An on-going review of the records schedule had highlighted the majority of records across Remediation did not have the requirements specified to demonstrate compliance with Sellafield arrangements. I therefore noted this as a systematic and significant failure to implement compliance arrangements across the Remediation value stream.

I identified the following area for improvement during the compliance inspection and this has been raised as a Regulatory Issue which will be managed as part of normal regulatory business:

The Licensee to ensure an adequate records schedule is put in place for the Remediation value stream.

LC 9 Inspection

I examined evidence of the licensee’s compliance with its arrangements for LC 9 and consider, on the basis of my sample, that the licensee is compliant with its duties under LC 9. I identified no areas for improvement during the compliance inspection which warranted a regulatory issue.

Conclusion of Intervention

The LC 6 compliance inspection concluded that the licensee has not adequately implemented its arrangements for compliance with LC 6. I therefore consider, noting the ONR guidance on inspection ratings, that an inspection rating of Amber (seek improvement) is merited and a Level 3 regulatory issue has been raised.

The LC 9 compliance inspection concluded that the licensee has adequately implemented its arrangements for LC 9. I therefore consider, noting the ONR guidance on inspection ratings, that an inspection rating of Green (no formal action required) is merited here.
