This report covers a planned inspection at the AWE Burghfield Licensed Site and is undertaken in accordance with ONR’s Integrated Intervention Strategy (IIS) for the Atomic Weapons Establishment Programme.
The inspections undertaken at the Burghfield Licensed Site form part of a series of planned interventions in accordance with the IIS and Integrated Intervention Plan (IIP).
The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.
ONR conducted a planned inspection and assessment of implementation of the Licence Condition (LC) 28 Examination, Inspection, Maintenance and testing (EMIT) within the Assembly Facility on the Burghfield Nuclear Licensed Site.
ONR also conducted interventions on the Aldermaston Site’s Security Classification & Information Handling, Assembly Facility Periodic Review of Safety (PRS) Fault/Engineering Schedule, at the Director of Site Level 3 Regulatory Interface Meeting (RIM) and at the Burghfield Nuclear Licensed Site Level 3 RIM.
For the LC 28 compliance inspection, based on the sample inspected in respect of the established arrangements for LC 28 EMIT, ONR concluded that there was adequate evidence indicating that appropriate consideration was being given to the ageing and the lifetime extension of structures, systems and components within the Assembly Facility and that enhancements had been implemented since September 2006.
For the Aldermaston Site’s Security Classification and Information Handling, Assembly Facility PRS Fault/Engineering Schedule, at the Director of Site Level 3 RIM and at the Burghfield Nuclear Licensed Site Level 3 RIM, ONR was content with progress and did not consider there to be any need for regulatory action at this point.
It is my opinion that from the sample inspected, the implementation of the established arrangements within the Assembly Facility with respect to Licence Condition 28 is to an adequate standard.
There are no other findings from this inspection that could significantly undermine nuclear safety.
The planned interventions set out in the Integrated Intervention Strategy for Burghfield site remain valid and will be followed for future inspections.
