This report covers planned inspections at the Mensa project at 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 within the Mensa project of implementation of the Licence Condition (LC) 28 Examination, Inspection Maintenance and Testing.
For the Licence Condition 28 intervention, based on the discussions and explanations given, including the samples inspected, on this occasion I am satisfied that there were no shortfalls identified with the implementation of the LC28 arrangements. Therefore, I assessed that a 'Green' intervention rating was appropriate. I was also satisfied that sufficient information and evidence had been provided to recommend the closure of regulatory issue 4453.
It is ONR's opinion, that from the sample inspected, the implementation of the established arrangements within the Mensa project with respect to Licence Condition 28 is to a 'GREEN' rating. There are no other findings from this inspection or the other interventions in this report that could significantly undermine nuclear safety.
