Torness Power Station - Licence Condition 8 Compliance Inspection, and ONR participation in Euratom treaty article 35 verification inspection

Executive summary

Purpose of Intervention

The purpose of this intervention was to conduct a Licence Condition (LC) compliance inspection at EDF Energy Nuclear Generation Limited’s (NGL’s) Torness Power Station in accordance with the planned inspection programme contained in the Torness Integrated Intervention Strategy (IIS) for 2016/17.

Interventions Carried Out by ONR

This intervention included a compliance inspection against site Licence Condition 8, warning notices.

The nominated site inspector for Torness also participated in a European Commission verification under article 35 of the Euratom Treaty, and held a routine meeting with the station’s technical and safety support manager.

Explanation of Judgement if Safety System Not Judged to be Adequate

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

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

The ONR inspector conducted a planned inspection of EDF Energy NGL’s Torness site compliance with LC8 (warning notices). This inspection was performed in accordance with ONR guidance NS-INSP-GD-008, and examined the station’s arrangements and their implementation.

The ONR inspector sampled and reviewed a number of corporate and station procedures. The inspector also selected several areas on site, and found all warning notices inspected to be compliant with the station’s controlled plant book, used to identify and control the location of all warning notices on site.

Based on the inspector’s discussions with station personnel and the sampled inspection of procedures and their implementation on plant, the station’s compliance with the requirements of LC8 is judged to be adequate, and an IIS rating of GREEN is considered appropriate.

Also, in conjunction with representatives from the Scottish and UK governments, the Scottish Environment Protection Agency and other organisations, the ONR inspector supported the UK’s response to an independent statutory verification undertaken by inspectors from the European Commission. The purpose of this inspection was to verify compliance with the requirements of article 35 of the Euratom Treaty, which requires member states to comply with the European directive concerning the monitoring and control of levels of radioactivity in air, water and soil.

The EC verifiers commented favourably on the UK and station’s compliance with the requirements of article 35, and the main findings of their inspection will be made available on the European Union website.

Conclusion of Intervention

The nominated site inspector is satisfied that the arrangements and their implementation at Torness for LC 8 are adequate, and judges that the outcome of the sample inspection undertaken meets expectations detailed within relevant ONR inspection guidance. The site inspector has therefore assigned a rating of GREEN for LC8.

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.
