And all of that is made even worse because of the whole "nuclear" part, with plenty of critical parts becoming irradiated and essentially impossible to touch unless you let it rest for a couple of decades. On top of that it locks you in to an old reactor design, which might be very undesirable for safety reasons.
At a certain point it just becomes cheaper to build a brand-new one right next to it and decommission the old one, even with a nuclear reactor.

There are nuclear plants built in the 60s and 70s that are not only still operating but in the process of extending their operating licenses in order to keep operating for decades more. The period of time it takes before this makes "keep operating it" unviable is evidently pushing 80 years without actually hitting the limit.
Control rooms and reactor vessels are themselves made of modular components and a lot of maintenance to those things happens during refueling.

That can't be the argument against building new ones. It's the argument that what you want is to build the newer, safer designs and then operate those for a long time.
