Doubts have been raised about the continued operation of Hunterston B.

The current maintenance outage for inspection of the graphite core has revealed a number of cracks in the graphite bricks.

Some cracks are to be expected and a limited number are acceptable, but the arguments are regarding how many cracks are acceptable.

Cracking of the graphite is undoubtedly a limiting factor in the safe working life of the reactor, it remains to be seen if this is the end for this reactor or not.
I suspect that it will be allowed to run for another year or two, but not for much longer.

Under normal steady state operating conditions the cracks are of little consequence. The risk is that an earthquake could distort the core, prevent the insertion of the control rods and potentially prevent a controlled shutdown.

One reactor at Hunterston B was due to re start at the end of this month, but this has now been put back to the end of JUNE !

The other reactor is still listed as being expected to re start at the end of April, it remains to be seen if this be achieved.

Judging from the lack of response, Adam, no one is at all surprised about there being massive problems with ancient nuclear equipment. We're just waiting for the same to happen throughout the nuclear industry over the next few years and for the massive cost of decommissioning which the taxpayer, of course, will be expected to fund but which we will not hear about for quite a few years yet.

Not a problem. Carry on until you decide that it can't be restarted at all.
