Well design lifetime is only really relevant at the design stage. I would hope they're proceeding on how the the reactor is now, regardless how how long it was designed to last. I don't per se have a problem with them changing safety limits, if we know more about how things behave, it seems sensible. I suppose the question is still, is it safe? Regardless of number of cracks, the design life time, or the actual age.
