The purpose of this intervention was to carry out licence compliance inspections at the EDF Energy Nuclear Generation Limited’s (NGL’s) Torness power station in line with the planned inspection programme contained in the Heysham 1 Integrated Intervention Strategy (IIS) for 2015/16.
ONR mechanical specialists carried out inspections against the requirements of Licence Condition (LC) 28, Examination, Inspection, Maintenance and Testing (EIM&T) to inform the ONR decision relating to the issue of a Licence instrument for Consent for return to service of Reactor 2 following its statutory outage. The activities examined were selected due to their nuclear safety significance and agreed in advance of the visit with the Torness station and site inspector.
The inspection included:
The inspection was supported by inspection visits to the following areas:
The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.
Based on my sampling, I am satisfied from a mechanical engineering perspective that during the Torness 2015 Outage:
Also, suitable and sufficient records are been kept and monitored to identify problems both re-actively and pro-actively.
This report presents the findings of the mechanical engineering intervention of the LC28 EIM&T arrangements in place to support the 2015 Torness Reactor 2 periodic shutdown.
Based on my sampling undertaken as part of this intervention, I am satisfied that the LC 28 arrangements in place are adequate and have been adequately implemented and therefore I have given LC28 an IIS rating of 3 – Adequate. This intervention will form part of the Mechanical Engineering Assessment Report for the 2015 Torness Reactor 2 Outage.
