Compliance inspections at AWE Burghfield

Executive summary

Purpose of intervention

The purpose of this intervention was to undertake Licence Condition (LC) compliance inspections at Burghfield in line with the planned inspection programme contained in the AWE Integrated Intervention Strategy and associated Intervention

An additional reactive intervention was undertaken for Licence Condition (LC) compliance for the Burghfield Assembly Periodic Safety Review (PRS2).

Further contact was made with AWE on Mensa progress. Routine regulatory meetings for the Burghfield Nuclear Licensed site and Capital Projects were also held.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable during this inspection.

Key Findings, Inspector's Opinions and Reasons for Judgements Made

From the evidence sampled during this inspection I judge that AWE’s arrangements to comply with the requirements of LC19 are adequate in that they meet the majority of ONR’s expectations. During the inspection I witnessed no significant shortfalls in the implementation of those arrangements so I have rating them as ‘Green’ with no formal regulatory action required.

From the evidence sampled during this inspection I judge that AWE’s arrangements to comply with the requirements of LC20 fall short of ONR’s expectations. During the inspection I witnessed that the project did not comply with current corporate arrangements so I consider that a “seek improvement” request be identified to AWE.

Conclusion of Intervention

Based on the planned compliance inspections undertaken against the requirements of licence condition 19, I consider that the licensee has adequate arrangements to comply with the licence condition, and is implementing the requirements of those arrangements, such that no formal regulatory action is required. Against the requirements of licence condition 20, I consider that the licensee should improve in the compliance with corporate arrangements. I will progress this matter using the ONR Regulatory Issues process.

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 Mensa remains valid and will be followed for future inspections.

Details of the reactive LC14 inspection are set out in Intervention Record ONR-OFP-IR-16-122.
