Hartlepool Power Station EDF Energy Nuclear Generation Limited (NGL) Planned LC2 & LC14 Compliance Inspections

Executive summary

Purpose of intervention

The purpose of this intervention was to undertake planned compliance inspection activities at EDF Energy Nuclear Generation Limited's (NGL's) Hartlepool power station, in line with the ONR's planned inspection programme.

Interventions Carried Out by ONR

We undertook an intervention to evaluate implementation of NGL's arrangements made in accordance with licence condition (LC) 2 (marking of the site boundary) and LC 14 (safety documentation). The intervention involved:

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

Not applicable.

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

In respect to LC2 compliance, we found that site boundary is effectively delineated by signage and fencing. Based on a sample inspection, we found that these structures were in an acceptable condition. EDF's arrangements for LC2 compliance and their implementation were judged to meet ONR's expectations and therefore assigned an inspection rating of: Green.

Based on our sample inspection of LC14 arrangements, we concluded that EDF have effective systems to manage safety case documentation produced via the safety case anomalies process. Records produced via this process are suitably retrievable from EDF's computer based document management system. Staff interviewed during this intervention demonstrated a sound and effective knowledge of the safety case.

ONR's previous LC14 inspection found that delays had occurred to Hartlepool Power Station's programme of safety case health reviews. During this inspection, we found that EDF has made substantial progress in this area, although some work remains to complete EDF's 2016 review. Our previous finding will be closed when EDF present an ONR a prioritised programme for continuing development the Hartlepool Power Station safety case, demonstrating how the principal findings from the health review will be addressed. EDF agreed to provide this assurance.

EDF agreed to review its process (known as directed reading) by which briefing notes advising operations staff of changes to the safety case are issued.

We judged that the overall standard of compliance was generally consistent with relevant good practice, with some minor potential areas of improvement identified. I therefore award the following inspection rating against LC14: Green.

Conclusion of the Intervention

There are no findings from this inspection that could significantly undermine nuclear safety and no change to the planned interventions and inspections of Hartlepool are required. The entry on the ONR Issues Database generated following ONR's previous LC14 inspection will be updated to reflect the findings of this inspection. Progress will be monitored by the site inspector during future visits to the site.
