- Site: Dounreay
- IR number: 18-176
- Date: January 2019
- LC numbers: 26
The purpose of this visit was to undertake inspection activities at Dounreay Site Restoration Limited (DSRL) in accordance with the 2018/19 Integrated Intervention Strategy (IIS) for Dounreay to confirm that the licensee is controlling its hazards and complying with its statutory obligations.
Interventions Carried Out by ONR
The following activities were completed:
- Review of progress against regulatory issues as recorded on the ONR Regulatory Issues Database and other regulatory actions agreed during previous ONR inspection activities [IIS Code 102];
- Meeting with the site safety representatives [IIS Code 106];
- Review of DSRL’s internal regulation activities [IIS Code 108];
- Attendance at the Dounreay Site Stakeholder Group [IIS Code 103].
This inspection also provided the opportunity to conduct a plant visit to PFR as part of the continuing schedule of activities to support ONR’s assessment of LC26 [Control and supervision of operations].
Explanation of Judgement if Safety System Not Judged to be Adequate
Key Findings, Inspector's Opinions and Reasons for Judgements Made
For each of the areas inspected:
- We consider that DSRL continues to make good progress against the action plans agreed to address regulatory issues raised during previous interventions on site.
- Additionally, DSRL continues to progress a range of activities aimed at improving its arrangements in those areas where previous ONR inspections have identified opportunities for improvement.
- We continue to have good confidence in DSRL’s internal regulation capability and consider that the risks identified to senior management from their activities align with ONR’s observations.
This inspection provided an opportunity to conduct a plant walk-down within PFR. We observed lifting activities associated with the preparations for the removal and treatment of the residual Na within the RPV. We consider that there was a clear demonstration of the adequate control and supervision of these high hazard activities.
Conclusion of Intervention
Overall, we consider that the site is making adequate progress in addressing matters raised in previous inspections and continues to demonstrate an adequate internal regulation capability. We did not identify any matter impacting on nuclear safety that required any further immediate regulatory action.
