EDF Energy has received approval from the United Kingdom’s Office for Nuclear Regulation (ONR) to restart the Hunterston B power station’s Unit 3 for a limited run, according to August 27 announcements from both the company and the regulator. EDF has permission to operate the unit for up to 16.425 terawatt days (approximately six months of operation), the ONR said.

EDF also announced that Hunterston B—located in North Ayrshire, along the western coast of Scotland—will begin its defueling phase no later than January 7, 2022, more than a year earlier than the expected retirement date of March 2023. The decision, EDF said, was made following a series of executive board and shareholders meetings.
