Unit 1 Periodic Shutdown - Inspection of Electrical Related Aspects

Executive summary

Purpose of intervention

This report covers the nuclear safety related inspection of EDF Energy Nuclear Generation Ltd (NGL) Hartlepool Nuclear Licensed Site, undertaken as part of a series of planned interventions of the Unit 1 statutory shutdown.

Interventions Carried Out by ONR

The inspection considered the electrical work being undertaken as part of the Unit 1 periodic shutdown, including the planned work from the outage intentions document (OID) and any emergent work in this area.

This intervention was an information exchange inspection assessing the Licensee's progress in the implementation of Licence Conditions (LCs) 28 and 22 arrangements for Unit 1 electrical outage activities.

Explanation of Judgement if Safety System Not Judged to be Adequate

The current inspection was not a safety system inspection, and therefore this section is not applicable.

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

An inspection of Unit 1 outage-related electrical activities was carried out as part of the programme of outage-related safety inspections included on the Hartlepool site intervention plan for 2014 to confirm that the planned examination, maintenance, inspection, test and modification activities are undertaken during the outage period.

During the course of the inspection it was found that station is maintaining its electrical plant and equipment in accordance with its arrangements, on the basis of the areas sampled by the inspection.

In summary, the overall outcome from the safety inspection of the outage-related electrical activities of Unit 1 are that the implementation of the LC 28 and LC 22 arrangements for the electrical equipment are deemed to be satisfactory and an IIS rating of 3 has been awarded to these activities.

Conclusion of Intervention

From the information gathered and evidence obtained during this intervention, no matters have been identified that are likely to have a significant impact on nuclear safety on the station at this time. Therefore, I consider that no additional regulatory action arising from this visit is necessary currently. The outcome from the inspection has been captured within the station event and action tracking arrangements as necessary, in the actions recorded in this intervention report, and in the ONR issues database as appropriate.

The overall outcome from the inspection is that no electrical issues have been identified from this work that should affect the return to service of Unit 1, on completion of the planned and emergent work.

There are no recommendations arising from this intervention.
