Planned Compliance Inspection at Hartlepool Power Station

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake licence condition (LC) compliance inspections at EDF Energy Nuclear Generation Limited's (NGL) Hartlepool Power Station, in line with the inspection programme contained in ONR's Operational Facilities Division intervention strategy.

Interventions Carried Out by ONR

I performed an intervention to evaluate NGL's compliance with the following nuclear site licence conditions (LCs), which are applicable provisions of the Energy Act 2013:

The LC11 inspection examined the licensee's arrangements to identify the resources required to respond to emergencies which may occur on the site. The inspection comprised meetings with staff, examination of documentation, and walkdown of a sample of emergency equipment.

During my LC22 inspection, I examined the licensee's arrangements to control modifications to its catalogue of spares and consumable materials.

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

Not applicable - no system based inspections were performed during this intervention.

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

LC11 - Emergency Arrangements

I confirmed by means of a sample inspection that claims made in the Station's boiler tube failure safety case and external hazards assessment had been accurately implemented within the station's emergency procedures. I also confirmed that emergency equipment claimed in the safety case was available for use by suitable qualified and experienced personnel. Overall, I was satisfied that sampled claims had been effectively implemented and judge that the following Inspection Rating against LC11 is appropriate: Green.

I noted one minor compliance shortfall in relation to NGL's managerial arrangements for review of emergency operating instructions. NGL agreed to address this finding. I have raised an ONR regulatory issue to track resolution of this finding to closure.

LC22 - Modifications or experiments on existing plant

I selected a number of changes to the catalogue of plant spares made with the past two years for sample inspection. I confirmed that documentation had been prepared in accordance with NGLs arrangements. I judge these documents had been subject to review and approval by competent staff consistent with ONR's expectations for LC22. I identified some minor areas for improvement to the NGL's arrangements for control changes to plant spares control, which were accepted by NGL. An ONR regulatory issue has been raised to track these findings to completion. Overall, I was satisfied that arrangements for the control of changes to plant spares were effectively implemented and judge that the following Inspection Rating against LC22 is appropriate: Green.

Conclusion of Intervention

There are no findings from this inspection that could significantly undermine nuclear safety. No additional regulatory action is needed over and above the planned interventions at Hartlepool Power Station as set out in the site's intervention strategy, which will continue as planned.
