Dounreay - Emergency arrangements

Executive summary

Purpose of intervention

In line with the 2014/15 inspection plan for Dounreay I carried out planned inspections and other interventions to provide confidence that Dounreay Site Restoration Limited (DSRL) is controlling its hazards properly and complying with its statutory obligations.

Interventions Carried Out by ONR

I carried out a planned inspection for compliance with Licence Condition 11 (LC11, Emergency Arrangements). I participated in a planned system based inspection of emergency equipment and a planned intervention on Leadership and Management for Safety (L&MfS) both of which are reported elsewhere in colleagues' Intervention Reports. I had update meetings on fuel strategy and the annual site funding limit. I participated in a meeting of the Dounreay Stakeholder Group.

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A

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

The focus of discussions on LC11 compliance was an issue which came to light in the 2013 and 2014 emergency exercises revealing an apparent conflict between (a) managing casualties and the radiological release, and (b) securing a lockdown to minimise the security threat. I am content that DSRL understands the importance of the lockdown issue and will explore the issue in its response to ONR comments on the 2014 emergency exercise.

DSRL is making satisfactory progress with fuel strategy projects. The safety case for constructing the new unirradiated fuel characterisation facility (UFCF) is expected to be sent to ONR in November. Prior to that there is a workshop to discuss the UFCF safety case, and there is a site visit for the ONR assessment team in December. ONR is also expecting safety case proposals for ancillary construction ahead of the UFCF, and for the transfer from Dounreay to Sellafield of unirradiated fuel assemblies.

DSRL is on track to confirm to ONR in November the conclusions of its annual site funding limit discussions with NDA.

Conclusion of Intervention

The intervention did not identify any matter impacting on nuclear safety that required immediate regulatory action
