The two reactors at Hunterston B nuclear power plant near Ardrossan are 43 years old - the oldest in Europe.
They're already well beyond their operating lifetimes, which have twice been extended by EDF Energy, and they're scheduled to close down for good in 2023.
However,
there's a serious safety fault in the reactors. The fault is known as
keyway root-cracking: where the graphite moderator cores in the reactors
develop cracks leading to instabilities that could lead to a major
nuclear accident: which would lead to a large swathe of Scotland's
central belt having to be evacuated.
"In the very worst case the hot graphite core could become exposed to air and ignite leading to radioactive contamination of...the metropolitan areas of Glasgow and Edinburgh."
The reactors have been closed since October 2018 as a
result, but owners EDF Energy are currently making a case for turning
them back on, with help from trade union GMB.
Although the
probability of a meltdown is still low, the consequences could be
incredibly severe. In such an event, both Glasgow and Edinburgh would need to be entirely evacuated due to radioactive contamination.
