Dounreay Inspection in support of IIS

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 planned inspections for compliance with Licence Condition (LC) 11 (Emergency Arrangements); LC4 (Restrictions on Nuclear Matter on the Site); and LC15 (Periodic Review).  I took part in various update meetings.  I participated in a meeting of the Dounreay Stakeholder Group Site Restoration Sub Group.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

On LC11, I raised two Regulatory Actions on DSRL to confirm to ONR:  (1) its relationship with NHS, to ensure that there is adequate medical cover for dealing with contaminated workers when Dounreay is operational, and (2) the close-out of an issue related to the inconsistency in the application of site lockdown.  These Actions will be followed-up as part of my interventions on site relating to LC11.

ONR had asked DSRL to consider combining its Emergency Plan and Counter-Terrorism Plan to better integrate safety and security arrangements.  However DSRL has decided to maintain the two Plans as separate documents but will ensure that future revisions are mutually consistent in respect of integrating safety and security emergency responses.

Generally DSRL is making satisfactory progress with fuel strategy projects.  DSRL readiness to start sub-assembly transfers is satisfactory provided there is no change to the choice of transport package.  However there continue to be delays with the delivery of the safety case for constructing the proposed unirradiated fuel characterisation facility.

DSRL remains in control of the safety case periodic review process.

Conclusion of Intervention

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