Hartlepool - Planned Compliance Inspection

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake compliance inspection activities at EDF Energy Nuclear Generation Limited’s (NGL) Hartlepool power station, in line with the ONR’s inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS) for 2018/19.

The interventions also sought to gather evidence for Chemistry-related aspects for the forthcoming Periodic Safety Review 3 for Hartlepool and Heysham 1 stations, as well confirm the adequacy of actions to be taken at Hartlepool as a result of the identified ‘National Blackout’ fault.

Interventions Carried Out by ONR

In my capacity of nominated site inspector for Hartlepool Power Station, accompanied by Chemistry and Fault Studies specialist inspectors as appropriate, I performed interventions to examine the licensee’s implementation of its compliance arrangements with regard to the following nuclear site licence conditions (LC):

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

In addition to the compliance inspections, I also met with Independent Nuclear Assurance staff, and the station’s Technical, Safety & Support manager to discuss progress of regulatory issues at the station.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable – no system based inspections were completed during this intervention.

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

The key findings of this intervention were:

Conclusion of Intervention

Overall, I judge that the standard of compliance was consistent with relevant good practice and I am satisfied that the licensee is complying with its legal duties.  Items for potential improvement were fed back to the station; I do not consider it proportionate to raise any regulatory issues to track progress of these observations.

There are no findings from this inspection that could undermine nuclear safety at this time.  At present, no additional regulatory action is needed over and above the planned interventions at Hartlepool Power Station.
