There are eight boilers per reactor arranged similar to the finger holes on a
dial telephone around the core.

So if one boiler spine is faulty, the other seven must be suspect.
That's why they have closed the entire reactor down.

That was my point expressed in other posts. The designs of those two sites *in
their entirety* are as close as makes no difference. Could come to nothing,
but given similar operating hours, the severity / distribution of any defects
and capabilities to effect a number of parallel repairs or even replacements it
could quite easily lead to the loss of up to 2.3GW of generation on a temporary
or extended basis.

OTOH it could be that one spine was made with substandard materials or
was under a leak for years


Also despite the headlines Reactor 2 at Heysham 1 is at this point still
generating albeit with reducing load before being shut down for the boiler
inspection.
