LC11 Emergency Arrangements

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake compliance inspection activities at EDF Energy Nuclear Generation Limited’s (NGL) Heysham 1 and Heysham 2 power stations, in line with the ONR’s inspection programme contained in the relevant ONR Integrated Intervention Strategies (IIS) for 2020/21. Due to the restrictions still in place due to Covid-19 the inspection was conducted remotely via Skype with relevant documents shared before and after the inspection.

Interventions Carried Out by ONR

The main focus of the intervention was to conduct a planned compliance inspection on LC11 – Emergency Arrangements. The inspection was conducted by the nominated site inspector for Heysham 2 and the Operating Reactors lead for LC11.

It was conducted utilising the Emergency Preparedness and Response Capability Map (EPRCM). This is a framework used to evaluate emergency planning and response in the context of seven subject areas. ONR aims to evaluate all areas of the EPRCM on each operating reactor site during a five-year cycle.  During this inspection we sampled evidence from several sections of the Capability Map.

Key Findings, Inspector's Opinions and Reasons for Judgements Made

Due to the inspection taking place remotely no physical inspection took place of onsite facilities or equipment. We interviewed the Emergency Preparedness Engineers (EPE) for both sites. The EPEs had updated the respective capability maps prior to the inspection. Using the capability maps we sampled evidence from several sections of the Capability Map,

The evidence presented was consistent with the claims in the capability map and we found that since the previous update a number of areas have improved and no significant shortfalls were identified.

During the inspection we found evidence of compliance with both station-specific and fleet-wide processes for both stations. We felt that in some areas additional information could be presented in the capability map of existing station arrangements to improve the evidence and claims.

We identified some areas that will be discussed with the NGL fleet lead for emergency arrangements to improve consistency across all stations, though these did not impair the emergency response capability at either station.

Conclusion of Intervention

In relation to LC11, we judged that an inspection rating of Green (no formal action) is warranted for both stations. There are no findings from this inspection that could significantly undermine nuclear safety.
