This was a planned inspection of EDF Energy Nuclear Generation Ltd's (NGL's) Hinkley Point B power station, undertaken as part of the planned intervention strategy for the Operating Facilities Programme (OFP) of the Office for Nuclear Regulation (ONR).
The work was carried out in-line with the planned inspection programme contained in the Hinkley Point B Integrated Intervention Strategy (IIS).
I (the nominated site inspector for Hinkley Point B) with support from ONR inspectors:
No system based inspections were carried out on this visit.
For LC7 (incidents on the site): I was satisfied that NGL was following its procedures for identifying and resolving conditions adverse to quality across the site. I was satisfied that investigation of the events and corrective action was being taken in a timely and professional manner. I noted the ongoing enhancements that were planned to the corrective action process on site but consider that NGL has implemented a good quality and robust process. I therefore assigned an inspection rating of Green - no formal action required - to this inspection.
For LC12 (duly authorised and other suitably qualified and experienced persons): I was satisfied that NGL had clearly defined the role of duly authorised persons on site and had a good process in place to control their management. NGL had established a good training programme with appropriate accreditation and records and maintained a register of duly authorised persons on the site. I therefore assigned an inspection rating of Green - no formal action required - to this inspection.
Annual Review of Safety: The report and meeting agenda were presented to the format requested by ONR in a timely manner. The review included a presentation by NGL of the station performance over the past year and a plant walk down which identified a number of safety enhancements that had been implemented throughout the year and other on-going activities. The review meeting focused on the station performance over the past year and allowed relevant good practices and areas for improvement to be discussed. ONR was content with the outcome of the review meeting.
Safety Representatives: I met with two of the site safety representatives to discuss matters on the site including the workings of the Health and Safety Committee, welfare facilities across the site, access to the charge machine, hand vibration legislation, lost time accidents, numbers of industrial safety engineers on the site, control of laptops and safety rules events.
Independent Nuclear Assurance: On this occasion there were interactions with INA personnel during the annual review of safety and in separate one to one discussions. We discussed planned changes to the INA arrangements on site and progress with a number of initiatives on site.
Information Exchange: I held an information exchange meeting with station staff to gather information on the on-going programme of work to replace the gaseous activity monitoring equipment on both reactors.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
There were no findings from this inspection that could significantly undermine nuclear safety. At present, no additional regulatory action is needed over and above the planned interventions of Hinkley Point B power station as set out in the Integrated Intervention Strategy, which will continue as planned.
