Heysham 2 LC36 Compliance Inspection, LC32/34 Meeting, and INA Discussions

Executive summary

Purpose of intervention

The purpose of this intervention was to undertake a Licence Condition (LC) compliance inspection at EDF Nuclear Generation’s (NGL’s) Heysham 2 power station in line with the planned inspection programme contained in the Heysham 2 Integrated Intervention Strategy (IIS) for 2014/15.

Interventions Carried Out by ONR

This intervention involved a compliance inspection against Licence Condition (LC) 36, Organisational Capability.

In addition, I held the quarterly ONR Issues Database meeting as well as other meetings associated with environmental examination, inspection, maintenance and testing, and emergency arrangements.  The Independent Nuclear Assurance (INA) Site Evaluator was involved in a number of the discussions held with Station staff.  The Environment Agency Site Inspector was involved in the discussions associated with the environmental maintenance aspects.

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 LC36 compliance inspection focussed on the following areas as part of the sample into the arrangements and their associated implementation:

As a result of the areas sampled for my inspection, I am content that the arrangements and their implementation associated with LC36 are to a good standard and I therefore rated this element of my inspection through the IIS as 2 (good).

The meetings attended during this inspection provided useful information in order to inform future interventions including a mechanism to capturing future regulatory commitments associated with environmental maintenance and the upcoming annual LC11 Emergency Arrangements annual demonstration exercise.  I was satisfied that station was progressing with addressing the areas discussed in a satisfactory manner.

The review of the ONR Issues Database did not identify any significant shortfalls or areas of concern such that they required elevation in relation to categorisation or further regulatory attention.  There are minor updates required to some issues, but overall NGL continue to address the current open issues at Heysham 2 in a satisfactory manner.

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

Feedback was provided to the Technical Safety and Support Manager relating to the outcome of the compliance inspection performed as well as the other meetings and discussions that were held. 

I am satisfied that the arrangements and their implementation at Heysham 2 for LC36 are to a good standard and judge that the outcome of the sample inspection undertaken met with the expectations detailed within ONR guidance.  I have therefore rated my intervention an Integrated Intervention Strategy (IIS) rating of 2, good.

There are no findings from this inspection that could significantly undermine nuclear safety and no change to the planned interventions and inspections of Heysham 2 are required.
