EDF Torness, LC26 Inspection

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake compliance inspections at EDF Energy Nuclear Generation Limited's Torness power station in line with the ONR's planned inspection programme contained in the Torness Integrated Intervention Strategy (IIS) for 2017/18.

The intervention was part of ONR's regulatory oversight of the management of a planned outage of Torness reactor 1.

Interventions Carried Out by ONR

I carried out an inspection over a series of dates concerning compliance with Licence Condition 30, which concerns shut down of the plant for maintenance, and LC 26 which requires all work which may affect safety to be carried out under the control and supervision of suitably qualified and experienced persons. It included unannounced visits to site, in some cases outside normal hours, in accordance with the IIS.

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

I also record here a number of additional engagements at Torness connected with the outage.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable - no system based inspections were performed during this intervention.

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

The intervention involved observation of work on the site over a series of dates, discussion with the people involved (both contractors and EDF staff) and review of relevant documents and records.

For LC30, the activities I sampled indicated that the outage was being managed adequately, with appropriate prioritisation of safety, and suitable oversight and leadership of the maintenance work.

For the sample observed for inspection of LC26, I found that there was adequate control and supervision. Staff were well briefed, evidently competent and generally working safely. Safety documents were in order and evidence was readily available demonstrating the competence of nominated 'Field Supervisors'.

Conclusion of Intervention

On the basis of these samples, I judge that compliance with LC 30 by Torness was adequate and I have rated the inspection GREEN.

On the same basis I also rate compliance with LC26 as GREEN.

There were no findings from this inspection that could significantly undermine nuclear safety or which would result in changes to the planned interventions and inspections of Torness Power Station.
