Planned Compliance Inspection

Executive summary

Purpose of intervention

I carried out planned inspections of compliance with licence condition (LC) 23 (operating rules), LC 24 (operating instructions) and LC 26 (control and supervision of operations) 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 implementation of its arrangements for compliance with LC 23, LC 24 and LC 26, focussing on the sodium destruction plant (NDP) in the Dounreay Fast Reactor (DFR) and the irradiated fuel caves (IFC) in the Prototype Fast Reactor (PFR).  Both are projects requiring the licensee’s highest level of safety controls.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

Overall I consider that the licensee meets the expectations set out in ONR’s guidance on the inspection of LC 23, LC 24 and LC 26.  There was a minor instance of apparent non-compliance in PFR, but I did not see any evidence that this was indicative of a systematic failing.  There were also some examples of good practice; the use of hold points in operating instructions to ensure key safety managements requirements are complied with, and the instruction-specific competency definition documents (and associated assessments).

Conclusion of Intervention

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