A power outage has taken place at one of the reactors at Hunterston B Power Station since Thursday.

The 480-megawatt reactor is scheduled to come back on line on Thursday March 23, but the 'News' understands it could return to action as of tomorrow.

An EDF Energy spokesperson said: “One of the reactors at Hunterston B power station came offline on Thursday evening due to a fault on the control fluid system in the turbine generator. The fault occurred in the conventional non-nuclear part of plant. The reactor was taken offline safely and cooling was maintained at all times. There were no safety or environmental impacts. We are currently investigating the cause of the fault and the reactor will be returned to power along with the turbine generator as soon as maintenance is satisfactorily completed.”
