The UK’s Office for Nuclear Regulation (ONR) has given permission for EDF to restart two advanced gas-cooled reactors at the Hinkley Point B power station in southwest England for a limited period of operation.
Permission for Hinkley Point B-1 will allow it to operate to a core utilisation of 17.55 terawatt days, while permission for Hinkley Point B-2 is to operate to a core utilisation of 17.3 terawatt days, which equates to two periods of approximately six months operation for each reactor.
