Not just the cooling circuit - the whole chamber.
Reactor continuing to operate despite this - testimony to RR PWR engineering.
Trying to find the name of the vessel...
Yes extraordinary indeed. So extraordinary it sounds like bollocks.
Reactor ( kettle ). No tunnels anywhere. Although there is a separate access. The opening of which notified Burghfield /Aldermaston immediately. Interesting aside, also the venue for Sunday service.
