EDF to restart unit 3 of 1.2 GW Hunterston B power station in UK

EDF Energy Nuclear Generation has secured approval from the UK’s Office for Nuclear Regulation (ONR) to restart operations of the Reactor 3 of the 1,220MW Hunterston B nuclear power station in Ayrshire, Scotland.

The ONR’s permit allows the company to resume operations of the Reactor 3 for a limited next period of operation and the permission is for up to 16.425 terawatt days, which is approximately six months. The power plant’s advanced gas-cooled reactors 3 and 4 were shut down in 2018 due to the identification of cracks on the graphite core during routine inspections at the facility.
