Torness Power Station 2015 Periodic Shutdown – Radiological Protection Inspection and LC30 Recommendation

Executive summary

Purpose of intervention

This intervention report is on an inspection I undertook at Torness (TOR) power station, in relation to the 2015 statutory outage of reactor Unit 2.  It was conducted as part of a series of planned interventions related to the TOR statutory outage.

The aim of this intervention was to establish whether EDF Energy, Nuclear Generation Ltd’s (the Licensee) statutory outage work programme for TOR, scheduled for completion between 10th July and the 9th September 2015, was being conducted in compliance with the Ionising Radiations Regulations 1999.  Relevant ONR guidance was used during the inspection, in particular, Nuclear Safety Technical Inspection Guide, NS-INSP-GD-054 Revision 4.

My conclusions on these matters informed the development of my overall opinion of the Licensee’s readiness to bring reactor Unit 2 back to power in due course.

Interventions Carried Out by ONR

The following matters were addressed during the intervention:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

My inspection did not reveal any significant nuclear safety issues, relevant to reactor Unit 2 start-up in due course, that required action by the Licensee or follow-up by ONR.  My discussions with the Head of Radiological Protection at the Station and his team indicated their strong commitment to effective radiological protection practice and a good level of compliance with the IRR99 was evident during plant inspections;  accordingly, I have assigned an IIS rating of 2. 

Conclusion of Intervention

From a radiological protection standpoint, I was content with the Licensee’s conduct of its statutory outage work programme and with its level of compliance with the IRR99.

On the basis of my inspection of the IRR99 aspects of the Unit 2 outage, I recommend that support be given for a Consent under licence condition 30 to allow Unit 2 at the Station to return to normal operating service
