DRDL - Planned LC7 Inspection

Executive summary

Purpose of Intervention

This intervention was held to ensure that there are adequate arrangements for the notification, recording, investigation and reporting of incidents that occur on sites, and that these arrangements have been effectively implemented. This inspection was undertaken as part of a series of planned interventions supporting ONR's DRDL intervention strategy.

Interventions Carried Out by ONR

ONR carried out a planned Licence Condition (LC) 7 (incidents on site) compliance inspection in line with the ONR Technical Inspection Guide NS-INSP-GD-004, LC 7 Incidents on site, and IAEA guidance NS-G-2.11. The scope was shared with DRDL in advance of the inspection.

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

This inspection covered the following areas:

In general progress with the implementation of improvements in the LC7 arrangements has been maintained.

Although nuclear safety was not affected, an issue was identified in DRDLs arrangements for the management, tracking and close out of actions. This related to existing or historic actions only. DRDL have developed and are currently trialling a new draft process that does have a mechanism for prioritising actions and historic action in two major databases however there are a number of other databases with potentially safety related actions which are not being dealt with or reported to high level DRDL management as outstanding.

In my opinion this is a gap against relevant good practice for the effective planning, organisation, control, monitoring and review of the preventive and protective measures. Therefore I will raise a Level 4 regulatory issue.

Conclusion of Intervention

This inspection was rated green.
