Dounreay - LC36 compliance inspection and IIS 100 Series inspection activities

Executive summary

The purpose of this intervention was to undertake a Licence Condition (LC) compliance inspection and to conduct a number of the Code 100 series of inspection activities at Dounreay Site Restoration Limited (DSRL) in accordance with the 2018/19 Integrated Intervention Strategy (IIS) for Dounreay to confirm that the licensee is controlling its hazards and complying with its statutory obligations.

Interventions Carried Out by ONR

The purpose of this intervention was to conduct an inspection of DSRL’s arrangements against the requirements of LC36 [Organisational capability] and to review progress against the implementation of those arrangements in support of the Voluntary Early Release (VER) programme.

This intervention provided the opportunity to undertake a number of other activities, specifically:

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A

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

For the LC36 compliance we focused on those activities in place to manage the DSRL Voluntary Early Release programme (VER).  We discussed the role of the transition board and examined the information generated and used by this board to ensure the programme is conducted in accordance with DSRL’s ‘management of change’ (MoC) arrangements; this board also ensures that adequate mitigation is in place to address any potential concerns identified during the scrutiny of the MoC proposals for each of the individual areas across DSRL.  We also examined the knowledge capture and management arrangements implemented to support the VER programme.

Overall we were satisfied that DSRL has adequate arrangements in place to manage the impact of the VER programme on the continued safe operation of the site. While we still consider there to be shortfalls with regard to the analysis of the cumulative impact of the programme, we consider that the Transition Board should be able to mitigate the impact of those shortfalls.

With respect to other activities:

Conclusion of Intervention

Overall we are satisfied that DSRL has adequate arrangements in place to manage the impact of the VER programme on the continued safe operation of the site and is making adequate progress in addressing regulatory issues previously raised with DSRL.
