AWE -  LC17 Supply Chain inspection  

Executive summary

Purpose of Intervention

This intervention was a Supply Chain themed LC 17 “Management Systems” inspection. It took place at AWE Aldermaston 04/12/2018. The purpose was for AWE to provide ONR with assurance that they have adequately implemented Supply Chain processes for managing the risk of Counterfeit, Fraudulent and Suspect Items (CFSI) and the obsolescence of safety significant components.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

The AWE policy for CFSI was judged to be adequate. The contract clauses and supplier auditing were also considered to be adequate. However, AWE had not provided sufficient detail to demonstrate that all the requirements of their CFSI policy have been implemented. Furthermore, some commitments made to ONR for completion in 2015 had not been carried out.

AWE’s routine asset procurement process was judged to be adequate against relevant good practice. For obsolete items, the LC 22 modifications process is used for significant changes. Other changes are subject to a different “like for like” or equivalence process. AWE were not able to show that nuclear safety was considered for this “like for like” or equivalence process.

AWE supply chain has described good engagement with their suppliers for items that are due to become obsolete. This involves bulk purchases. However, AWE supply chain is not accountable for the company wide obsolescence strategy. As a result, the overall strategy for managing the overall risk from obsolescence could not be articulated.

The following regulatory findings have been identified:


The AWE representatives have responded well to ONR’s intervention. They articulated effective practices and best endeavours to comply with regulatory expectations. The majority of the intervention met the regulatory expectations and aligned with relevant good practice.

A number of regulatory findings have been identified. These are findings where AWE was not able to satisfactorily demonstrate a requirement or provide sufficient clarity. Therefore I judge that the intervention is therefore rated AMBER “seek improvement”. ONR will re-engage.
