This report covers the inspection of Research Sites Restoration Ltd's (RSRL's) Harwell licensed site, undertaken as part of interventions outlined in the ONR Plan for the Regulation of the Harwell and Winfrith Sites 2014/2015. The interventions undertaken consisted of both planned and reactive activities
The inspections undertaken at site focussed principally on compliance inspections for Licence Condition 21- Commissioning and Licence Condition 22 - Modification or Experiment on Existing Plant.
No system based inspections undertaken during this intervention.
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.
From the evidence gathered during this intervention, I do not believe there are any matters that may immediately affect nuclear safety.
