Hartlepool intervention plan

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 Operating Reactor Lead and the Nominated Site Inspector.

Interventions Carried Out by ONR

This inspection was focussed on the annual review of safety.

This intervention included compliance inspections against the following Licence Conditions (LCs):

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 (the nominated site inspector) concurred with the station's annual review self assessment. The licensee has performed strongly in operating rule compliance and training. I acknowledged commendable work done in response to the Japanese earthquake. There is room for improvement in the emergency scheme manning, and back up equipment, for example, the high pressure back up cooling system. Following a number of fire events this year ONR specialist inspectors are pursuing improvements in the supervision arrangements and event investigation.

Timely outage preparation is a precursor to a successful outage and good quality control. Although the outage plan showed delays in milestone closeout in some areas, the extant work in progress tended to be limited to small areas. I considered progress was adequate and have therefore rated this element through the IIS as 3 (adequate).

Conclusion of Intervention

The ONR team expressed gratitude for the effort the station put into attending and preparing for the annual review of safety. The review provided an opportunity for the station to reflect on their performance over the past year. In general I found the station's self assessment was consistent with my own. The review had captured the successes, challenges and looked ahead to the forward plans.

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