Date(s) of inspection:
- August 2023
Aim of inspection
To provide regulatory confidence in the implementation of the Hartlepool Unit 2 2023 Statutory Outage Intentions Document in relation to Mechanical Engineering.
To provide evidence to inform the ONR decision relating to the issue of a Licence Instrument for a Consent for return to service of Hartlepool Unit 2, on completion of the work.
ONR Inspection Guidance to be utilised during the inspection can be found at: http://www.onr.org.uk/operational/tech_insp_guides/index.htm
Subject(s) of inspection
- LC28 – Examination, inspection, maintenance and testing – Rating: Green
Key findings, inspector’s opinions and reasons for judgement made
I consider that the licensee has adequately demonstrated its examination, inspection, maintenance and testing of Mechanical Engineering equipment. My judgement is based on sampling the following during the Hartlepool Reactor 2 periodic shutdown:
- Emergency Boiler Feed Pumps;
- Gas Circulator Non-Return Valves; and
- Auxiliary Gas Dryer changeover valve G/225
During the intervention, several minor issues were identified. I consider that these were adequately addressed by the licensee and do not require a regulatory issue for formal follow-up.
Based on my sampling undertaken during this intervention, I consider that the licensee has adequately demonstrated its Mechanical Engineering examination, inspection, maintenance and testing (EMIT) arrangements and their implementation.
Hence, during the periodic shutdown I consider the licensee has adequately demonstrated compliance with Licence Condition (LC) 28. I have not identified any issues that would prevent EDF Nuclear Generation Ltd.’s Hartlepool unit 2 from returning to service. I judge that a GREEN inspection rating is appropriate.
Based on my sampling during this intervention, I:
- consider that the licensee’s EIMT activities have adequately demonstrated compliance with LC28;
- consider that the licensee has adequately applied EIMT relevant good practice (RGP); and
- have not identified any issues that would prevent EDF Hartlepool Unit 2 from returning to service.
Hence, I judge that a green rating, against ONR’s inspection rating guide is appropriate for this intervention.
