Licence Condition Compliance Inspections covering LC7, LC12 and LC15

Executive summary

Purpose of intervention

The purpose of this intervention was to conduct Licence Condition (LC) compliance inspections at EDF Energy Nuclear Generation Limited’s Torness Power Station in line with the planned inspection programme contained in the Torness Integrated Intervention Strategy (IIS).

Interventions Carried Out by ONR

This intervention included compliance inspections against the following Licence Conditions (LCs):

Explanation of Judgement if Safety System Not Judged to be Adequate

No safety system inspection was undertaken, hence this is not applicable.

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

The processes and procedures used at Torness Power Station to notify, record and investigate events on site were inspected. This inspection sampled the arrangements and their implementation and concluded that they were adequate to comply with the requirements of LC7. In addition, observation was made of a Corrective Action Review Board meeting that provided evidence that events are correctly investigated, appropriately analysed in terms of potential trends and the remedial actions taken to prevent recurrence.

We were satisfied that implementation of the arrangements for compliance with LC7 at Torness Power Station are to an adequate standard and judge that the outcome of the sample inspection undertaken satisfied relevant expectations in ONR guidance.

The LC12 inspection examined the arrangements in place at Torness Power Station to ensure that personnel undertaking tasks which may impact the safety of the plant are duly authorised and suitably experienced and qualified to perform these roles. The inspection was carried out with personnel from the Operations Group and focussed on the training of Central Control Room personnel. Evidence provided was sampled to establish that all relevant personnel are effectively trained and subject to reviews to make sure that they remain suitably experienced and qualified to work in these roles that are important to safe operation of the plant. In addition, processes used at Torness Power Station when changes are introduced, for example, to Station Operating Instructions, in the form of refresher training that occurs on a routine basis were sampled. We also found that the control and supervision of safety significant operations within the Central Control Room at Torness Power Station are undertaken by duly authorised persons.

We are satisfied that implementation of arrangements for compliance with LC12 at Torness Power Station are adequate and judge that the outcome of the sample inspection undertaken met with relevant expectations in ONR guidance.

Our inspection of the arrangements in place at Torness Power Station for LC15 considered the previous periodic safety review (referred to as PSR2) and activities undertaken to ensure that all identified corrective actions from this review are closed in a timely manner. This inspection found that the Licensee was able to demonstrate that the work was being adequately controlled and provided evidence that measures, which incorporate independent oversight, are in place for a small number of corrective actions that are currently open from PSR2. The arrangements for development of the next periodic safety review (referred to as PSR3) were discussed and it was noted that a scooping document is to be prepared for submission to the Licensee’s Nuclear safety Committee in September 2015.

We are satisfied that implementation of arrangements for compliance with LC15 at Torness Power Station are adequate and judge that the outcome of the sample inspection undertaken met with relevant expectations in ONR guidance.

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

Conclusion of Intervention

We are satisfied that the arrangements and their implementation at Torness for LC7, LC12 and LC15, respectively, are adequate and judge that the outcome of the sample inspections undertaken met expectations detailed within relevant ONR guidance.  We have therefore rated the respective LC7, LC12 and LC15 elements of this intervention an IIS rating of 3, adequate.

There are no findings from this inspection that could significantly undermine nuclear safety and no change to the planned interventions and inspections of Torness Power Station.
