The purpose of this intervention was to carry out licence compliance inspections at EDF Energy Nuclear Generation Limited’s Hinkley Point B power station in line with the planned inspection programme contained in the Hinkley Point B Integrated intervention Strategy for 2018/19.
ONR inspectors carried out inspections against the requirements of Licence Condition 28: examination, inspection, maintenance and testing, to inform the ONR decision relating to the issue of a licence instrument for consent for return to service of Hinkley Point B Reactor 4 following its periodic shutdown. The activities examined were selected due to their nuclear safety significance.
The intervention included:
Examination, inspection, maintenance and testing of:
walk downs of the associated maintenance facilities/areas
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
Based on my sampling, I am satisfied from a mechanical engineering perspective that during the Hinkley Point B Reactor 4 2018 periodic shutdown:
Based on my sampling undertaken as part of this intervention, I am satisfied that the Licence Condition 28 arrangements in place are adequate and have been adequately implemented with no significant shortfalls. I have therefore given this inspection an Integrated Intervention Strategy rating of Green.
I would therefore support a request under Licence Condition 30 to return Hinkley Point B Reactor 4 to operation following its 2018 periodic shutdown.
