Planned participation in the quarterly regulatory review meeting with the Urenco UK Limited licensee and the Capenhurst Nuclear Services Limited tenant organisation, together with a reactive meeting requested by the licensee and a meeting to review aspects of the licensee’s emergency arrangements. The intervention formed part of the 2015/16 ONR intervention programme at the Urenco UK Limited licensed site at Capenhurst.
I participated in the planned quarterly regulatory review meeting with the Urenco UK Limited licensee and the Capenhurst Nuclear Services Limited tenant organisation, accompanied by other ONR inspectors engaged on current interventions at Capenhurst.
The licensee requested a meeting to discuss a forthcoming organisational change, which was to be imminently announced to the contractor supplied ‘guard force’ and the contractor supplied ‘on site’ fire and rescue team.
A meeting was held to review aspects of the licensee’s recently drafted “Capability Map”, responding to a detailed question set provided in advance by ONR.
No safety system inspection was made during this intervention.
Regulatory advice was provided on a broad range of matters discussed at this useful review meeting. The licensee’s periodic safety review of safety cases was reviewed, noting that the licensee’s recovery programme for the preparation and implementation of interim “justification for continued operation” interim safety cases, pending the completion of the delayed COSER safety cases for each of the enrichment facilities, was progressing adequately. An acceptable rate of implementation of short term improvement measures was reported by the licensee. The licensee and Capenhurst Nuclear Services Limited tenant organisation’s progress with site decommissioning progress was reported, with an acceptable outcome. Acceptable progress with the decommissioning of the contaminated East Side Curtilage area was reported. Asbestos remediation was progressing satisfactorily, as was an electrical substation demolition project. It was also reported that a number of redundant radiation sources had been disposed from the site. The movement of older type 48 “Hex Tails” cylinders, to clear space for the Legacy Cylinder Facility, was reported to be imminent.
In response to the licensee’s proposed organisational change, affecting services provided to the licensee by a contractor, regulatory advice was provided on the related necessary regulatory permissioning matters.
From the discussion at this meeting, at which the ONR attendees sampled aspects of the licensee’s “Capability Map”, I ascertained that the licensee had submitted a comprehensive document, appropriately detailing the rationale and supporting evidence. During the meeting, a number of aspects of the licensee’s response were queried, including the implementation of arrangements for assessing the competency of people appointed to key roles in the emergency arrangements. Some of the supporting evidence presented by the licensee was sampled, with supporting instructions being found to be subject to appropriate periodic review.
In view of the recent progress reported with the licensee and the CNS tenant organisation’s decommissioning projects, a licence condition 35, decommissioning, intervention rating of “3”, adequate, was considered appropriate for this intervention.
For the proposed organisational change, I formed the view that the licensee, prior to this meeting, had not fully recognised the extent of regulatory engagement necessary on this topic, which would be required for ONR to formally approve the proposed organisational change. In view of the brevity of the meeting, no intervention rating was warranted.
Regarding the licensee’s “Capability Map”, it was concluded that the licensee had submitted an adequately comprehensive document, appropriately detailing the rationale and evidence in response to the detailed questions from ONR, albeit with some areas for improvement readily acknowledged by the licensee. In view of the brevity of this meeting, no intervention rating was warranted.
