Office for Nuclear Regulation

Planned LC 22 Compliance inspection

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake a regulatory inspection at EDF Energy Nuclear Generation Limited (EDF NGL) Heysham 1 Power Station in accordance with ONR’s Integrated Intervention Strategy (IIS) 2018-2019 for the Operating Reactors Sub-Division.  This report covers the nuclear safety-related inspection of Heysham 1 power station, which was undertaken as part of routine planned and reactive interventions.

Interventions Carried Out by ONR

As part of this intervention, I (the Nominated Site Inspector), carried out a planned compliance inspections against the following licence condition:-

I also accompanied the incoming Nominated Site Inspector as part of formal handover arrangements, undertook information gathering exchanges with Station personnel and reviewed recent incidents reported to ONR under LC 7 arrangements.

The interventions were based on sampling the implementation of the arrangements in place at the station against the licence condition and ONR inspection guidance.

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

I found the arrangements in place to comply with LC 22 to be in line with the expectations of ONR guidance and from the sample of evidence seen during my inspection these are being complied with at Heysham 1.  I rated this inspection as Green for compliance with arrangements with no regulatory issues being raised.

I am satisfied that the Station has taken appropriate action in response to recent incidents reported to ONR under Licence Condition 7 – Incidents on the site.  No matters of concern were identified that I consider require a regulatory action or formal investigation to be taken at this time.

Conclusion of Intervention

After considering the evidence examined during the inspection against Licence Condition 22, I concluded that the licensee arrangements were in line with expectations of ONR inspection guidance and an inspection rating of Green was determined for all aspects.

There are no findings from this intervention that could significantly undermine nuclear safety.  At present, no additional regulatory action is needed over and above the planned interventions at Heysham 1 Power Station.
