EDF Energy has found cracks in key parts of its Hunterston B nuclear power plant.
Today the energy generator confirmed cracks were found in two of the 6,000 graphite bricks in one of two Hunterston B reactors.
Just two months ago EDF shut two other nuclear plants after finding a “defect” in a boiler spine of one of them, the structure which holds together the boiler in the reactor.
The latest news is totally unrelated according to the firm which said the cracks are “expected” at the nuclear plant over its lifetime.
Colin Weir, Station Director at Hunterston B said: “It will not affect the operation of this reactor and we also expect that a few additional cracks will occur during the next period of operation.
“The small number of cracked bricks found during routine inspection is in line with our expectations, the findings have no safety implications and are well within any limits for safe operation agreed with our regulator.”
Anti-nuclear campaigners at WWF claimed this showed how “increasingly unreliable” nuclear power plants will be in future.
