Hartlepool - Planned intervention

Executive summary

Purpose of intervention

This is a planned inspection at EDF Energy Nuclear Generation Limited's (NGL) Hartlepool Power Station, undertaken as part of the planned integrated intervention strategy (IIS) for the Civil Nuclear Reactor Programme (CNRP).

The inspection was performed by the ONR Nominated Site Inspector.

Interventions Carried Out by ONR

I inspected compliance with licence condition 28, examination, inspection, maintenance and testing with respect to the progress and conduct of the reactor 1 statutory outage and the reactor 2 forced outage.

I also agreed the scenario for the level 1 emergency demonstration exercise.

The licence conditions were inspected against ONR's published guidance requirements (as described in our technical inspection guides).

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

I felt the station are responding in a systematic fashion to the discovery of a boiler spine anomaly at Heysham 1 and the consequent shutdown of the 4 reactors at Heysham 1 and Hartlepool. The station has thus far continued to retain planned resource and maintain the programmed scope of statutory outage work (reactor 1). Separate resource has been allocated to address the boiler spine issue. However, a recovery plan has yet to be fully developed.

The station are maintaining compliance with their operating rules despite challenges due to low pressure back up cooling pump unavailability and the discovery of failed fuel in reactor 2.

On this basis I consider an IIS rating of 3 (adequate) against LC28 is appropriate.

Conclusion of Intervention

Three start up issues will be entered onto the outage issues database:

I have rated this LC 28 element of my inspection through the IIS as 3 (adequate).

There are no findings from this inspection that could significantly undermine nuclear safety and no change to the planned interventions and inspections at Hartlepool.
