Exercise Annual Review Meeting, Emergency Planning and Consult Committee

Executive summary

Purpose of intervention

The purpose of this intervention was to undertake Licence Condition (LC) compliance inspections at EDF Nuclear Generation Limited'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 included compliance inspections against the following Licence Conditions (LCs):

In addition I attended an outage readiness review meeting the Heysham Site Emergency Planning Consultative Committee (EPCC).

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 LC11 inspection involved attendance at the Heysham 2 Exercise Annual Review Meeting (EARM). The purpose of the meeting was to review the status of emergency arrangements, progress any issues from emergency plan tests, actions from previous exercise review meeting and discuss future exercise objectives. I consider that the performance by Heysham 2 over the past year in relation to the emergency arrangements and their implementation at site is adequate based upon the information presented including the areas for development and hence I have rated this element of my inspection through the IIS as 3 (adequate).

The LC7 inspection involved consideration of both generic and local implementation documents as defined within MCP1 with the following areas covered as part of the inspection:

I am satisfied that the arrangements and their implementation for LC7 are to an adequate standard and have rated this element of my inspection through the IIS as 3 (adequate) due to the good practices associated with the Organisational Learning Portal balanced with the apparent common factors associated with plant alignment and human performance associated with a number of recent minor events at Station. Station has also identified these common factors and is addressing those as part of an investigation that is on-going.

The LC13 involved consideration of both generic and local implementation documents and included the following areas as part of the inspection:

Arrangements in place associated with changes made to LCs for which NSC advice should be sought prior to coming into force or being implemented.

Sample of minutes of the NSC relating to a Heysham 2 submission.

I am satisfied that the arrangements and their implementation for LC13 are to a good standard and have rated this element of my inspection through the IIS as 2 (good). This score has been allocated given the robust nature of the implementation of the arrangements including capturing of formal advice by the NGL internal regulator, and the extent of challenge provided by the NSC in relation to the modifications sampled.

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

I am satisfied that the arrangements and their implementation at Heysham 2 for LC7 and LC11 are to an adequate standard and judge that the outcome of the sample inspection undertaken met with the expectations detailed within ONR guidance. I have therefore rated these elements of my intervention an Integrated Intervention Strategy (IIS) rating of 3, adequate.

I am satisfied that the arrangements and their implementation at Heysham 2 for LC13 is 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 this element of 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.
