Sellafield Ltd, Licence Condition Arrangements Inspection, Licence Conditions 14 and 15

Executive summary

Purpose of intervention

This was a planned ‘Licence Compliance Arrangements’ inspection, supporting ONR’s 5-year rolling programme across the licence conditions to ensure Sellafield Ltd (SL) is managing the Sellafield site safely.  It was performed to determine:

The adequacy of SL’s arrangements for compliance with Licence Conditions 14 (Safety Documentation) & 15 (Periodic Review), and

If the arrangements covered all relevant activities performed by SL.

Interventions Carried Out by ONR

Licence Condition (LC) 14(1) requires the licensee (SL) to “…make and implement adequate arrangements for the production and assessment of safety cases…”.

LC 15(1) requires the licensee (SL) to “…make and implement adequate arrangements for the periodic and systematic review and reassessment of safety cases.”.

This inspection was performed in two parts:

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A.  This was not a system based inspection.

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

It is my opinion that SL’s arrangements for LC 14 & 15 are largely compliant with the expectations chosen from national and international guidance; this is demonstrated through the ‘requirements listings’ populated during the inspection.  The listings show evidence taken from SL’s arrangements (and discussions with SL staff) and align it with the chosen requirements.

Seven areas were found where compliance was not fully demonstrated, however in each case, there was at least some evidence towards a demonstration of compliance.

For that reason, along with others such as SL’s own drive for improvement and ONR’s current work to secure improvements in some of the identified areas, I have judged that these areas when aggregated are not sufficient to affect the IIS rating.

Only one action was identified (under LC15; for SL to consider how best to report progress on Long Term Periodic Review (LTPR) specific work), which will be progressed as routine regulatory business by the LTPR Project Inspector.

Conclusion of Intervention

I have rated SL’s current arrangements for both LC14 & LC15 as 3, adequate.  This is consistent with the IIS rating guidance for level 3:

"Arrangements meet guidance requirements.  Some opportunities for improvement under ALARP…  Site inspector able to identify minor points for improvement."
