SL Security and Resilience Directorate, ONR Capability Map Review

Executive summary

Purpose of intervention

As part of a programme of work initiated by the Department of Energy and Climate Change (DECC), ONR will during 2015 undertake reviews of the Emergency Preparedness and Response (EP&R) capabilities of all UK licensees.  The output from each review will be a completed “capability map”, a document setting out the levels of capability for a number of specific factors or attributes of Emergency Management (EM) at the site. 

This inspection was undertaken to ensure that all the evidence needed for the ONR team to complete and issue a capability map for the Sellafield site could be identified, reviewed, and discussed with the licensee where required.

Interventions Carried Out by ONR

Our inspection, which comprised discussions with SL staff and examination of site documentation and associated evidence of implementation of the same, was completed in accordance with the following formal ONR process guidance:

Though the capability map work is clearly related to the licensee’s duties under Licence Condition 11 (Emergency Arrangements), this was not an LC11 inspection and so no compliance rating was awarded.

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

The licensee has provided a significant body of evidence in support of its capability map submission.  The evidence provided prior to this inspection has been subject to further review and sampled evidence-gathering, and in the opinion of the inspection team, there are no major differences between the licensee’s rating of its capabilities and ONR’s, i.e. the licensee has undertaken a credible assessment.

The licensee’s submission highlights the need for improvements in the site’s emergency roll call (muster) performance.  A programme of improvements is therefore planned.  However, the current mustering issues identified at recent site-wide exercises are of sufficient concern to merit more frequent oversight by ONR, to monitor the pace and extent of delivery of these improvements.

Conclusion of Intervention

On the basis of the initial evidence provided, and from the additional information gathered during this inspection, we consider that the ratings in the ONR capability map for Sellafield will not differ significantly from those initially suggested by the licensee.  We have provided the specific rationale for the ONR capability map in a Supporting Note to this Intervention Record.

Our minor observations made during the inspection were shared with, and accepted by, the licensee as part of normal inspection feedback.  One ONR Regulatory Issue, to track planned improvements to the site’s emergency roll call, was raised as a result of this inspection.
