Let it run? You mean, presumably, the huge amount of testing and preventative and planned maintenance that is scheduled in as part of a reactors expected lifetime, plus anything new discovered along the way. That doesn't come for free.

Sure, given enough effort you can fix anything. But extending a fission plant's lifetime can require massive overhauls, replacing reactor components, replacing materials that have experienced radiation embrittling and activation, etc. Keeping a plant running indefinitely is so complicated and expensive that we haven't managed it so far.
Extension is something we should absolutely consider but it's not a magic fix all. Sometimes it's not worth it to keep an old thing running.
