Torness Power Station – Licence Condition Compliance Inspections covering LC7, LC11 (incl. emergency arrangements review meeting), LC27 and LC32

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 (NGL) Torness Power Station in accordance with the planned inspection programme contained in the Torness Integrated Intervention Strategy (IIS) for 2015/16.

This intervention was undertaken by the Nominated ONR site inspector for Torness, with the support of an ONR Inspector experienced in the topic of emergency preparedness and response.

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 LC7 inspection examined Torness’ compliance arrangements for ‘incidents on the site and other reporting and operating experience processes’, as well as the implementation of those arrangements. Our inspection sample focussed on the trending affected by reported events, events most frequently reported, the learning gained as a result of the reporting and trending of those events, and how this is used to bring about changes to reduce the frequency of events.

Based on our inspection sample, we judge that Torness’ arrangements and the implementation of those arrangements generally exceed guidance requirements. The site was proactive and positive during the intervention and no regulatory intervention was required.  For these reasons, we have given this inspection an IIS rating of 2 (good standard).

Our inspection of LC11 arrangements and implementation sampled Torness’ progress against the opportunities for improvement identified during the most recent emergency exercise. It was followed by a plant walkdown during which we viewed a wide range of emergency facilities, including equipment intended to improve the resilience of emergency arrangements on the station.

On the basis of the areas sampled, we judge that Torness’ arrangements and the implementation of those arrangements meet the requirements of ONR guidance. We have therefore given this inspection an IIS rating of 3 (adequate).

The LC27 inspection demonstrated that there was a clear line of sight from the safety case down to component level and that the processes in place demonstrate compliance with the licence condition. 

In addition to the delivery of a presentation which described the totality of the LC27 arrangements for the site, sampling of the asset management system was undertaken.   The site was proactive and positive during the intervention and it was judged that an IIS rating of 2 was appropriate.

The LC32 inspection demonstrated that the licensee has a good understanding of the nature of the waste produced on the site.  BEG/SPEC/SHE/008/032 was identified as the primary implementation document for the management of radioactive wastes which ensures that the requirements of the certificate of authorisation from the Scottish Environment Protection Agency (RSA/A/0070116/VN01) are complied with. 

The inspection included visits to the Active Solid Waste Building  and the Active Effluent Treatment Plant .  These areas were found to be clean, tidy and well organised.   The team demonstrated a great degree of enthusiasm and pride regarding their work and facilities.  We judged that Torness’ arrangements and the implementation of those arrangements generally exceed the requirements of ONR guidance and therefore we have given this inspection an IIS rating of 2.

The nominated site inspector also participated in two routine scheduled meetings:

with Torness’ Independent Nuclear Assurance (INA) team, during which emergency preparedness and the annual emergency arrangements review meeting were discussed.

with the Quality Management Group to review progress against actions and regulatory issues recorded in Torness’ and ONR’s databases respectively.

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 LC11 are adequate, and are of good standard for LC7, 27 and 32, and we judge that the outcome of the sample inspections undertaken met expectations detailed within relevant ONR guidance. We have therefore assigned a rating of 3 (adequate) for LC11 and of 2 (good standard) against LC7, 27 and 32.

There are 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.
