(Adds EDF Energy comment)
LONDON, May 8 (Reuters) - EDF Energy, owned by France’s EDF , has extended an outage at its Hunterston B8 nuclear reactor in Scotland to May 30 from May 14, regulatory data on the company’s website showed.
The reactor has been offline since October after routine inspections found cracks in its graphite core and this is the third delay to its restart.
EDF Energy is awaiting approval for the reactor’s restart from the Office for Nuclear Regulation (ONR) and said on Wednesday the new date was set “to support time for the ONR assessment”.
Neighbouring reactor Hunterston B7 has been down since March 2018 for the same reason and is due to come online at the end of June.
EDF Energy operates all 15 active nuclear reactors in Britain, which have a combined capacity of 9 gigawatts. Five reactors, with a capacity of 2.5 GW, are currently on outage.
