Compliance inspection – EAT and Industrial Hazards

Executive summary

Purpose of Intervention

The purpose of this intervention was to conduct a Licence Condition (LC) compliance inspection of EDF Energy Nuclear Generation Limited’s (NGL’s) Hartlepool power station, focused on plant tolerance to extreme ambient temperatures and the management of external industrial hazards. This was undertaken as part of a series of planned interventions that are listed in the Hartlepool Integrated Intervention Strategy for 2018/19.

The inspection was undertaken by an ONR External Hazards specialist inspector and an ONR External Hazards nuclear associate.

Interventions Carried Out by ONR

We performed an extreme ambient temperatures and external industrial hazards safety case informed inspection to examine the licensee’s implementation of its compliance arrangements with regard to the following Licence Conditions:

The inspections were based on a sample of the implementation of the licensee’s arrangements at Hartlepool power station against the Licence Conditions. The objective of the inspection was to determine whether the licensee’s arrangements were adequately implemented and in accordance with the extreme ambient temperatures and external industrial hazards safety case requirements.

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

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

During the course of this intervention, it was found that Hartlepool has arrangements to ensure that personnel, procedures and SSCs claimed within the extreme ambient temperatures safety case and external industrial hazards safety case are, and will remain, adequate. We observed a number of modifications to plant implemented in recent years which improve its resilience against extreme ambient temperatures. We observed liaison with local organisations and bodies regarding industrial sites in the area. The arrangements examined complied with the licensee’s legal duties based on the areas sampled during the inspection.

The key findings of the inspection were:

Conclusion of Intervention

After considering the evidence examined during the sample inspection undertaken against Licence Conditions 7, 11, 23 and 24, we concluded that the licensee complied with its legal duties regarding extreme ambient temperatures and external industrial hazards and met the requirements of the safety case.

There are no findings from this intervention that could significantly undermine nuclear safety at Hartlepool power station. At present, no additional regulatory action is needed over and above the planned interventions for Hartlepool power station as set out in the Integrated Intervention Strategy, which will continue as planned.
