French nuclear power company EDF restarted one of its UK reactors today after it was shut down earlier this week.
The 640 MW reactor at Torness power station in Scotland shut down unexpectedly on Monday after a fault on a fuelling machine.
A company spokesman said the fault has now been fixed and the reactor was re-synchronised to the grid this morning.
In October EDF took offline and then restarted three reactors, two because for refuelling and one due to an unplanned outage.
Earlier this month EDF’s nuclear fleet in the UK passed EU stress tests introduced in the wake of the reactor accident at Fukushima.
