This report covers a nuclear safety related inspection of Torness power station, undertaken as part of a series of planned interventions of the Reactor 1 (R1) periodic shutdown.
My inspection considered the electrical work being undertaken as part of the R1 periodic shutdown, including the planned work from the outage intentions document (OID) and any emergent work in this area.
This intervention was an inspection of the licensee's progress in the implementation of Licence Conditions (LCs) 22 and 28 arrangements for R1 electrical outage activities.
My inspection was not a safety system inspection, and therefore this section is not applicable.
My inspection of R1 outage related electrical activities was carried out as part of the programme of outage related safety inspections included on the Torness site intervention plan for 2013/14 to confirm that the planned examination, maintenance, inspection, test and modification activities are undertaken during the outage period.
During the course of my 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 my safety inspection of the outage related electrical activities of R1 is that the implementation of the LC 22 and LC 28 arrangements for the electrical equipment are deemed to be satisfactory. I have therefore given an inspection rating 3 (adequate) in respect of LCs 22 and 28.
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 my inspection is that no electrical issues have been identified from this work that should affect the return to service of Reactor 1, on completion of the planned and emergent work.
I recommend that actions resulting from this intervention and listed in this report should be monitored during future electrical inspections, with their resolution recorded in subsequent intervention reports for Torness Power Station
