Review of Proposed Emergency Arrangements

Executive summary

Purpose of intervention

This report covers an inspection of Magnox Ltd's Dungeness A licensed site, undertaken as part of a programme of planned interventions as outlined in the IIS plan for 2014/15.

Interventions Carried Out by ONR

During this intervention, two exercises were observed, that were designed to demonstrate how Magnox intends to create emergency arrangements for sites that do not require a local authority off-site emergency plan.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

During both exercises, we observed deficiencies in command and control at a number of locations. For both exercises, we judged that the principles of command and control were not demonstrated.

Staff who should have controlled the event were too involved in the detail and at times overwhelmed. The licensee was advised that event control locations should be adequately staffed with personnel having clearly defined roles.

At the incident location, casualty handling was considered to be good. However contamination control was identified as an area that needs to be improved.

Conclusion of Intervention

The licensee is maintaining a full capability for its current emergency arrangements and therefore nuclear safety is being maintained. As a result of witnessing both exercises, ONR has identified shortcomings with the licensee's proposed emergency arrangements and has given advice on its expectations. The licensee has been made aware that ONR Approval of new emergency arrangements is required before they can be implemented.
