LC 10 & 12 compliance inspections, Rim & LC34 arrangements

Executive summary

Purpose of intervention

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

Interventions Carried Out by ONR

During this intervention I carried out the following inspections/activities:

The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.

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 LC10 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 consider them to have been implemented appropriately. 

From the evidence sampled during this inspection, I judge that AWE’s implementation of its arrangements to comply with the requirements of LC12 is below standard.  During the inspection we had observed a number of shortfalls against relevant good practice.  Regulatory issues have been raised to monitor the resolution and improvement of the shortfalls identified.

Conclusion of Intervention

Based on the planned compliance inspections undertaken against the requirements of licence condition 10, I consider that the licensee has adequate arrangements to comply with the licence condition, and is implementing the requirements of those arrangements, appropriately.  We considered the shortfalls associated with licence condition 12 were sufficiently significant to nuclear safety that a below standard rating was appropriate.  I will monitor and confirm close-out of associated issues using the ONR issues database.
