Low Level Waste Repository - Licence Condition compliance inspection

Executive summary

Purpose of Intervention

This was one of a programme of planned inspections at the Low Level Waste Repository (LLWR) during 2019/20, developed in accordance with the Decommissioning Fuel & Waste Sub-Division strategy.

Interventions Carried Out by ONR

I inspected LLWR’s arrangements for compliance with Licence Conditions 2 (marking the site boundary), 7 (incidents on the site) and 8 (warning notices).

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable as no safety system was inspected.

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

I examined LLWR’s arrangements for: preventing unauthorised persons entering the site; notification, recording, investigation and reporting of incidents occurring on the site; and posting of notices for the location of emergency exits and measures to be taken in the event of a fire. I noted areas of good practice and offered advice regarding opportunities for improvement within LLWR’s arrangements.

Conclusion of Intervention

I concluded that LLWR’s arrangements for compliance with LCs 2, 7 and 8 were adequate, and that LLWR was able to provide demonstration that implementation of those arrangements is adequate.

The minor shortfalls within LLWR’s arrangements identified during the inspection had already been identified by LLWR’s internal assurance function and suitable actions placed to remedy these within adequate timescales. Completion of these actions will be monitored by the LLWR Independent Inspector and I do not consider further action by ONR is necessary at this time.
