LC7 and LC11 Compliance Inspections, Emergency Arrangements Equipment Systems Inspection

Executive summary

Purpose of intervention

I carried out a planned compliance inspection and a planned system inspection, in accordance with the Office for Nuclear Regulation’s (ONR’s) integrated intervention strategy for Sizewell A.

Interventions Carried Out by ONR

I inspected:

The site’s adherence to its arrangements for compliance with Licence Condition (LC) 7 (event notification, investigation and reporting) in a recent event involving the shipping of redundant heat exchangers to a metal recycling facility in Germany.

The site’s emergency arrangements equipment against the requirements of the approved emergency plan.

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A

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

I am content that the licensee has followed its procedures and has investigated the incident thoroughly.  I consider the event itself to have been low consequence.  The cause of the event appears to be the communication between the waste and project teams; all involved appear to have been following the correct procedures.  I note that changes to the licensee’s arrangements introduced since the dispatch of the heat exchangers (for reasons unrelated to this event) should serve to help prevent a recurrence.  A number of opportunities for improvement in other areas were identified by the licensee as part of their investigation, and the licensee is committed to making these improvements ahead of transition in March 2015, such that the future decommissioning organisation can benefit from them.

I consider that the licensee has the equipment necessary to implement its emergency arrangements; sufficient training and procedures are supplied to allow the use of that equipment; and the equipment is maintained to an appropriate standard.  Therefore I consider the requirements of the safety case to have been met.

Conclusion of Intervention

I found no issues that significantly affect nuclear safety, and nothing that required me to take further regulatory action.
