Office for Nuclear Regulation

LC14 and 15 Compliance Inspection

Executive summary

Purpose of intervention

I carried out planned licence condition (LC) 14 (safety documentation) and 15 (periodic review) inspections 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 the production and review of safety documentation, and discussed them with the safety case process owner.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

The safety case and periodic review process is broadly consistent with our safety assessment principles (SAPs) and the technical inspection guide (TIG) for LC 14 and LC15.  The guidance has in fact been reviewed against the SAPs, and it was clear to me that the process owner was familiar with the right first time safety case interventions that formed the basis of the TIG, and was actively engaged with the safety directors forum (SDF) safety case and periodic review working groups and the guidance they are producing.  The licensee’s procedures for periodic review already allow for proportionate review of decommissioning facilities, taking into account predicted changes in use of those facilities.  Nevertheless, given emerging priorities on site the licensee and ONR should continue to ensure the current arrangements achieve compliance and enable delivery of priority projects on site.

Overall I consider that the licensee’s arrangements for the production and periodic review of safety cases are adequate, with some good practices.  There are issues with timely delivery as a result of the availability of suitably qualified and experienced personnel.  The licensee is taking steps to address these, and ONR should continue to monitor them through its routine interactions. 

Conclusion of Intervention

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