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

Licence Condition 21 inspections of RSRL's arrangements and subsequent implementation in the Waste Encapsulation Plant (WEP) project it is evident that RSRL has made and implemented adequate arrangements for the commissioning of plant or processes. There are some areas for improvement in the clarity of the documented arrangements and alignment with regulatory expectations.

Licence Condition 22 inspections found that RSRL has made and implemented adequate arrangements for the modification or experiment on existing plant. There are some areas for improvement in the clarity of the documented arrangements and alignment with regulatory expectations. Inspection of implementation of the arrangements based on sampling a modification identified implementation is consistent with arrangements. Some areas for more robust implementation were observed and discussed with RSRL.

Both Licence Condition 21 and 22 inspections found that there is a lack of any process for providing responses to ONR primary powers however, further inspection has identified this is a generic issue for the majority of RSRL arrangements and is considered to be a result of weaknesses in Licence Condition 17, Quality Management, compliance.

Conclusion of Intervention

From the evidence gathered during this intervention, I do not believe there are any matters that may immediately affect nuclear safety.
