DRDL - LC17 Management Arrangements

Executive summary

Purpose of Intervention

This was a planned inspection of the supply chain management arrangements at Devonport Royal Dockyard Limited (DRDL) nuclear licensed site.

Interventions Carried Out by ONR

I carried out a planned compliance inspection against Licence Condition 17 (LC17) ‘management systems' focussing on the supply chain management arrangements. The objective of the intervention was to determine the adequacy of DRDL's supply chain management arrangements and their deployment against the regulatory expectations set out in NS-TAST-GD-077 ‘Supply Chain Management Arrangements for the Procurement of Nuclear Safety Related Items or Services' (TAG 77). I was satisfied that the objective set for this inspection has been achieved.

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

I found that DRDL's compliance with LC17 management systems for the areas inspected was adequate. (IIS Rating Green) however I noted that there is significant improvement activity for the Naval Marine business, of which DRDL is a constituent part, relating to the supply chain which ONR will monitor through routine Level 4 meetings with the supply chain team.

My key findings are given below:

Conclusion of Intervention

It is my judgement based on the discussions and supporting evidence provided that DRDL's supply chain management arrangements and their deployment are adequate (IIS Rating Green) and aligned with the regulatory expectations of TAG 77. I note the on-going rationalisation and improvement plans which will be monitored by ONR going forward. No formal actions have been raised; however a number of recommendations are made to carry the engagement forward.


The following recommendations are made:
