Dounreay Planned compliance inspection

Executive summary

Purpose of intervention

I carried out planned inspections of compliance with licence condition (LC) 19 (construction or installation of new plant) and LC 20 (modification to design of plant under construction) in accordance with the 2015/16 integrated inspection strategy (IIS) for Dounreay, to provide confidence that the licensee is controlling its hazards properly and complying with its statutory obligations. 

Interventions Carried Out by ONR

I inspected the licensee’s arrangements for compliance with LC 19 and LC 20 across the Dounreay site.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

The licensee’s engineering manual sets out the high-level process for all stages of the engineering lifecycle, including construction.  The process is consistent with other documents in the licensee’s management system (in particular, the process for the production and clearance of safety documentation) and is, in my opinion, clear and logical. 

The licensee uses its well-established Dounreay Modification Report (DMR) process to manage modifications to plant under construction.  ONR has previously inspected this process and considers it to be adequate.  I have considered factors specific to the modification of plant under construction as part of this inspection, and consider that the DMR process adequately deals with these factors.

Overall I consider that the licensee meets the expectations set out in ONR’s guidance on the inspection of LC 19 and LC 20.

Conclusion of Intervention

I did not identify any matter impacting on nuclear safety that required immediate regulatory action.
