Explanation of Judgement if Safety System Not Judged to be Adequate
N/A. This was not a systems-based inspection.
Key Findings, Inspector’s Opinions and Reasons for Judgements Made
I examined AWE’s planned progress on delivery of its LC36 improvement plan. My sampling focused on:
- AWE’s LC36 arrangements
- Progress on actions raised by AWE’s internal regulator
- Vulnerability management in a technology centre and the Operations function
- Follow up of extant regulatory issues
- Selected actions on the AWE LC36 improvement plan
- The AWE nuclear baseline
AWE provided evidence of adequate progress in all areas sampled.
Conclusion of Intervention
I judge that AWE’s progress against its LC36 improvement plan is adequate.
I judge that progress on the extant regulatory issues can be followed up through L3 and L4 regulatory interface meetings and that there is no requirement to continue with the quarterly LC36 inspections.
I judge that this inspection is rated green.
