This report covers a planned inspection at AWE Aldermaston Licensed Site and is undertaken in accordance with ONR’s Operating Facilities Division Weapons Sub-programme Strategy 2018 - 2020 for the Atomic Weapons Establishment Programme.
The inspections undertaken at the Aldermaston Licensed Site form part of a series of planned interventions in accordance with the ONR AWE Inspection Plan April ’18 - March ’19
Interventions Carried Out by ONR
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
The intervention was held within a facility on the Aldermaston Nuclear Licensed Site and was the annual demonstration of the arrangements in place to deal with an on-site nuclear emergency as required under LC11 and described in the Defence Programme Strategy.
ONR conducted an assessment of implementation of the Licence Condition (LC) 11, Emergency Arrangements through a Level 1 Emergency Exercise demonstration within a facility on the Aldermaston Nuclear Licensed Site.
ONR also conducted interventions on a facility Level 1 Emergency Exercise Presentation, Overview and Familiarisation Tour, a Level 3 Corporate meeting, Level 3 Structured Improvement Plan meeting and a regular meeting with the AWE Communications team.
For the LC 11 compliance inspection, based on the demonstration assessed in respect of the established emergency arrangements ONR concluded that the demonstration was to an adequate standard. The detailed comments of the inspection team for this demonstration will be summarised in a letter to the licensee.
For the Assembly Facility Level 1 Emergency Exercise Presentation, Overview and Familiarisation Tour ONR was satisfied that there were no shortfalls, that the exercise was realistic and sufficiently challenging and required no need for any regulatory action.
For the other interventions described in this report no new issues were raised and there is currently no requirement for further regulatory action in addition to that already planned as part of normal business.
It is ONR’s opinion that of the Level 1 Emergency Exercise Demonstration assessed, the implementation of the established emergency arrangements, on the Aldermaston Nuclear Licensed Site, is to an adequate standard, in respect of Licence Condition 11. A Green rating is therefore considered appropriate.
There are no other findings from this inspection that could significantly undermine nuclear safety. The planned interventions set out in the Operating Facilities Division Weapons Sub-programme Strategy 2018 - 2020 for the Atomic Weapons Establishment Programme remain valid and will be followed for future inspections.
