Hartlepool Power Station – Planned LC22 Inspection

Executive summary

Purpose of intervention

The purpose of this intervention was to undertake a Licence Condition (LC) compliance inspection at EDF Energy Nuclear Generation Limited’s (NGL’s) Hartlepool power station in line with the planned inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS) for 2015/16.

Interventions Carried Out by ONR

Assisted by an ONR Specialist Inspector, I undertook an intervention to evaluate standards of compliance against licence condition 22 (modification or experiment on existing plant). The inspection, which focused on implementation of NGL’s fleet wide arrangements to control modifications on operating plant, included interviews with personnel undertaking key roles in the process and examination of a representative sample of safety significant modifications which were approved during the past 12 months.

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 system based inspections were performed.

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

I found that staff undertaking roles important to safety understood their roles and responsibilities. Based on the sample of modifications examined, I found evidence which confirmed NGL’s process for verification, approval and peer review of proposed modifications is effectively implemented. I judge that the standard of compliance with LC22 is adequate, warranting an IIS rating of 3.

Conclusion of Intervention

From the evidence gathered during this intervention, there are no findings from this inspection that could significantly undermine nuclear safety. Accordingly, no changes are necessary to ONR’s planned inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS).
