Executive summary

Purpose of Intervention

The purpose of this ONR intervention was to undertake a planned inspection at Devonport Royal Dockyard Ltd (DRDL) Offices, Plymouth, in accordance with ONR’s Intervention Plan for the regulation of DRDL 2019/20.

Interventions Carried Out by ONR

The objective of the intervention was to observe the DRDL Board, examine DRDL’s Board arrangements, conduct structured interviews with selected Executive and Non-Executive Directors and assess the application of relevant good practice.

ONR utilised the following guidance and Relevant Good Practice (RGP) during this inspection:  Licensing Nuclear Installations, ONR, 4th Edition, Jan. 2015; Challenge Culture, Independent Challenge Capability (including an Internal Regulation function) and the provision of Nuclear Safety Advice, NS-TAST-GD-080 Rev 3; Safety Assessment Principles (SAPs) for Nuclear Facilities, ONR, 2014, Rev 0, Leadership and Management for Safety, MS.1 (Leadership); Function and Content of a Safety Management Prospectus, NS-TAST-GD-072 Rev 3; and UK Corporate Governance Code, July 2018 (UK CGC).

Conclusion of Intervention

On the basis of the areas sampled during the intervention, the inspectors judged that DRDL had established adequate arrangements for the DRDL Board and Executive. There was evidence that the licensee has made significant improvements in the arrangements, challenge culture and behaviours of the DRDL Board over the last 12 months.  This work has also included appropriate separation of Board and Executive functions, as described in relevant good practice. 

ONR understands that there are further improvements to be delivered by the licensee, and embedment of the revised arrangements and behaviours is vital – these aspects are part of DRDL’s continued improvement programme.  No major shortfalls with respect to relevant good practice for licensee Boards were identified during the intervention.

ONR will undertake a follow-up regulatory engagement in late 2020, to review progress and embedment of the revised Board and Executive arrangements and improvement programme.
