Executive summary

Purpose of Intervention

This intervention, conducted at the Licensee’s Devonport Royal Dockyard Limited Devonport licensed site was undertaken as part of the 2018/19 intervention plan and propulsion sub-division strategy.

Interventions Carried Out by ONR

I conducted a Licence Condition 4 (Restrictions on nuclear matter on the site) and 5 (Consignment of nuclear matter) compliance inspections, focused on the implementation of the licensee’s arrangements for the licence conditions, specifically their arrangements for refuelling activities. This intervention was conducted alongside the Defence Nuclear Safety Regulator who undertook an Authorisation Condition 4/5 inspection, noting DNSR are the responsible nuclear safety regulator for the consignment and transport of Ministry of Defence assets.

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

No findings were identified as requiring regulatory attention during the conduct of the compliance inspection.

Conclusion of Intervention

On the basis of the evidence sampled from the control of receipt, storage and consignment of new and used, the licensee demonstrated it has adequate arrangements in place to maintain compliance with Licence Condition 4 and 5. An Observation was raised to the ONR Nominated Site Inspector due to the absence of top level documentation demonstrating how the arrangements are coordinated to maintain compliance, and expectation within the relevant ONR TIGs. However, DRDL are actively engaged in enhancing these arrangements with a clear vision for the future being presented to ONR. ONR will continue to monitor delivery of this work during routine engagements.
