Heysham 1 - LC26 Planned Compliance Inspection

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake regulatory inspections 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. 

Interventions Carried Out by ONR

As part of this intervention the Nominated Site Inspector and Outage Project Inspector (hereto refer to as ‘I’), carried out a planned compliance inspection against the following licence condition:-

I also took part in the Independent Nuclear Assurance (INA) rapid trending review (RTR) for Reactor 2 periodic shutdown and undertook routine information gathering meetings.

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 undertook a planned unannounced intervention against LC 26, during which I,

I participated in the Heysham 1 (Reactor 2) planned outage Rapid Trending Review (RTR) process which aims to identify performance shortfalls in early stages of the outage. The focus of the RTR was Safety and Quality, specifically in the areas of Safety Rules/ Configuration management, Fire Safety and Industrial Safety. Two Areas for Improvement and one Opportunity for Improvement were identified during the RTR.

Conclusion of Intervention

After considering the evidence examined during the inspection against Licence Condition 26, ONR concluded that the licensee complied with its legal duties and an inspection rating of Green was determined.

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.
