Hartlepool - Planned Compliance Inspection

Executive summary

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.

Purpose of Intervention

I undertook an intervention to evaluate implementation of NGL’s arrangements made in accordance with licence condition 26 (Control and Supervision) and licence condition 24 (Operating Instructions) associated with work undertaken by the station’s maintenance teams.

The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides, which can be found at ) in the areas inspected.

Interventions Carried Out by ONR

The intervention was carried out by the ONR Site inspector and involved evaluation of the Protection Electrical Systems Group’s start of shift briefing, setting to work and observation of maintenance being undertaken on the station’s safety circuits.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable, no system based inspection undertaken.

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

In respect to control and supervision, the start of shift briefing I observed was undertaken systematically in accordance with NGL’s arrangements. The plant status and the days planned catalogue of work were effectively communicated. I observed a weekly safety circuits briefing, which provides a forum for maintenance technicians working on the reactor safety circuits to review the work conducted over the previous week and identify relevant learning to improve performance. I consider the approach to be an effective method of conducting a post-job debriefing. Overall, I considered that an inspection rating of ‘Green’ is warranted on the basis that the elements of control and supervision observed were broadly consistent with relevant good practice.

In respect to operating instructions, I sampled a calibration being undertaking on the reactor safety circuits and observed that work was undertaken diligently and systematically, in accordance with written procedures. In my opinion, the maintenance instruction in use was of good quality, providing an appropriate level of detail to ensure a consistent test approach. I provided feedback from my observations to the team leader. Overall, I considered that an inspection rating against of ‘Green’ is warranted against LC24

Conclusion of 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.
