This report covers an outage inspection of EDF Energy Nuclear Generation Ltd (NGL) Torness Nuclear Licensed Site undertaken during Reactor 2 periodic shutdown, in line with ONR’s Civil Nuclear Reactor Programme Strategy 2015-2020. The inspection focussed on electrical aspects of the Outage Intentions Document (OID) and was undertaken by an ONR specialist electrical inspector.
The inspection covered arrangements for Examination, Inspection, Maintenance and Testing under Licence Condition LC28.
Following this inspection I am satisfied that the outage work is being carried out in a satisfactory manner and I note that no significant issues were identified that would affect return to service. Minor issues which have been identified will be addressed by the station in accordance with their extant arrangements.
From the evidence gathered during this intervention, I am satisfied that the outage activities are being managed in an appropriate manner. With over 66% of activities completed no electrical issues have been identified from this work that should affect the return to service, on completion of the planned work. No items have been identified from the Outage Intentions Document which the station is planning to defer.
I will continue to monitor the outage work and will seek assurances from the station that all outage activities have been satisfactorily completed. Based on this intervention and subsequent interactions with the licensee I expect that OID electrical work will be completed, or appropriate deferrals justified under the station’s arrangements, and that I will be able to support a re-start of R2 and operation for a further period.
Examination, maintenance, inspection and test arrangements and activities sampled were found to meet requirements. Therefore an Integrated Intervention Strategy (IIS) Rating 3 has been assigned for LC28.
