Footage has been released of cracks found inside a reactor at a nuclear plant in Scotland.
The unit at Hunterston B in North Ayrshire has not been operating since the cracks were found to be growing faster than expected.
A planned inspection of the graphite bricks that make up the core of reactor three in March last year uncovered new “keyway root cracks”.
The firm has released footage of the cracks, which was taken in 2017 and 2018.
Station director Colin Weir told BBC Scotland: “Nuclear safety is our overriding priority and reactor three has been off for the year so that we can do further inspections.
“We have to demonstrate that the reactor will always shut down and that it will shut down in an extreme seismic event.”
