UK: Reactor 3 at Hunterston B remains offline, due to cracks in the graphite core

ONR 13th Nov 2018 , Reactor 3 at Hunterston B remains offline, after being shut down since a
routine inspection into cracks in its graphite core, in March. Cracking of
the graphite bricks in Advanced Gas-cooled Reactors such as Hunterston B is
expected as the reactors age.
However, the number of cracks found during
the inspection of Reactor 3 has led to the licensee, EDF Nuclear Generation
Limited, carrying out further inspections of the core. Reactor 4 at
Hunterston B was taken offline in October for an inspection of its graphite
core.
EDF Energy has submitted a safety case for Reactor 4 and is preparing
one for Reactor 3. The safety cases will be assessed by us to determine
whether the reactors are safe to return to service. Neither reactor may
restart without our consent, which will be given only if it is safe to do
so.    http://news.onr.org.uk/2018/11/hunterston-b-outages/
