Dounreay Conduct of Inspection in support of IIS

Executive summary

Purpose of intervention

In line with the 2015/16 inspection plan for Dounreay I carried out planned inspections and other interventions to provide evidence that Dounreay Site Restoration Ltd. (DSRL) is controlling its hazards properly and complying with its statutory obligations.

Interventions Carried Out by ONR

I undertook compliance inspection against Licence Condition 11 Emergency Arrangements, Licence Condition 32 Accumulation of Radioactive Waste and Licence Condition 36 Organisational Capability. I also attended a number of meetings to obtain the current position on site projects.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

My Licence Condition 11 inspection provided evidence that the actions resulting from the Delta 51 level 1 emergency exercise were being adequately progressed and planning for Delta 52 was in hand.

My inspection within the Waste Receipt, Assay and Compaction Facility confirmed that progress had been made to reduce the accumulation of low level waste on site.  The super-compactor is operational and a two shift system in place to reduce the backlog of waste arisings resulting from the failure of the previous super-compactor.  I also confirmed that the outcome of inspections and maintenance on the crane within the contact handleable intermediate level waste store proved it fit for future use to receive waste drums in store.  I concluded that there was an adequate standard of compliance against Licence Condition 32.

The revision of the Nuclear Baseline had identified a number of forward actions to address vulnerabilities identified throughout the baseline.  I considered that the process appeared to provide a sound foundation for improvement to organisational capability.  I also sampled the draft Management of Change to support re-organisation of the Fuels Directorate and noted that the peer review process appeared robust.  My inspection concluded that there was an adequate standard of compliance with Licence Condition 36.

Conclusion of Intervention

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