LC 7 Inspection - Sellafield Site Wide Infrastructure, Sellafield Ltd.'s nuclear licenced site at Sellafiell, Cumbria

Executive summary

Purpose of intervention

The Office for Nuclear Regulation (ONR) undertakes all regulatory interactions with Sellafield Limited (SL, the site licensee) against a strategy defined by the ONR Sellafield Programme.  The planned inspection schedule for the current regulatory year (covering April 2015 – March 2016), the content of which is guided by that strategy, identifies the Licence Conditions (LCs) that will be inspected over this period.

This intervention was undertaken to determine if the Infrastructure organisation is adequately implementing SL’s site-wide arrangements for compliance with Licence Condition 7 (Incidents on the site). The interaction focussed on Analytical Services (AS). The infrastructure site inspector will consider inspecting other areas of infrastructure in the next regulatory year against this licence condition.

Interventions Carried Out by ONR

Licence Condition 7 (LC 7) requires the licensee to make and implement adequate arrangements for the notification, recording, investigation and reporting of incidents occurring on the site.

My inspection, which comprised discussions with SL staff and examination of plant documentation, and observation of a local sentencing meeting, focussed on the following areas:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable; this was not a Safety System inspection.

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

I consider the facility’s implementation of the site’s arrangements for LC 7 is good in many areas.  For instance, there was evidence of effective sentencing of the incidents underpinned by good leadership, good knowledge from the staff interviewed, and a good level of reporting. These are, however, offset by the shortcomings in terms of the number of corrective actions not completed by their due date, the colour coding of the operating experience learnings not fully understood, and the absence of the records of coaching for investigators. For these reasons, I consider an IIS rating of 3 (Adequate) is merited against LC 7 as a result of this inspection.

Conclusion of Intervention

My findings were shared with, and accepted by, the dutyholders as part of normal inspection feedback. No ONR Regulatory Issues were raised as a result of this inspection.
