Aim of inspection
In accordance with the Office for Nuclear Regulation’s (ONR’s) Sellafield Strategy, each year ONR performs a series of planned inspections to seek assurance of compliance against selected licence conditions, targeted at those facilities with significant importance to nuclear safety. One such inspection was performed at Waste Treatment Complex (WTC) and Engineered Drum Stores (EDS) of the Alpha Operating Unit within the Remediation Value Stream to assess compliance with Sellafield Limited’s corporate arrangements for Licence Condition (LC) 7 (Incidents on the Site), in order to inform a regulatory judgement regarding the licensee’s compliance with its legal duties under the nuclear site licence.
Subject(s) of inspection
- LC7 - Incidents on site - Rating - Green
Key findings, inspector's opinions and reasons for judgement made
The inspection was undertaken on 8 December 2022 by the ONR Site Inspector for the Remediation Value Stream.
The inspection comprised discussions with Sellafield Limited personnel, review of records, documents and processes specific to WTC and EDS facilities within the Alpha Operating Unit of the Remediation Value Stream. I sampled several records including Condition Reports, investigation reports, corrective actions, governance records, trending, lessons learnt and training records. In addition, I observed the local Plant Operations Control Centre (POCC) and the Management Peer Review meetings and noted a good level of discussion and challenge.
From a mixture of sampling records and interviewing Sellafield Limited personnel, I saw evidence that WTC and EDS have an adequate reporting culture for issues impacting nuclear safety. I found that such issues were appropriately sentenced, investigated, and appropriate corrective actions raised, and subsequently closed with an adequate level of governance. Sellafield Limited provided me with confidence that learning from trending and analysis is used to drive improvements and understanding.
I consider that, on the basis of evidence sampled at the time of this inspection, the licensee has adequately implemented adequately its corporate arrangements for compliance with LC7 (incidents at the site) at WTC and EDS. I therefore consider that an inspection rating of Green (No Formal Action) is appropriate.
Conclusion
I consider that, on the basis of evidence sampled at the time of this inspection, the licensee has adequately implemented its corporate arrangements for compliance with LC7 (incidents at the site) at WTC and EDS. I therefore consider that an inspection rating of Green (No Formal Action) is appropriate.
