The article is about shutting down the reactors at the 31.12.22. As you know, they were not shut down at that date but ran some months more. That doesn't say anything about the long term maintenance requirements. And in any case they would have to be inspected before any further decisions to be taken as the article only states "they might be able to run further". But that was only an opinion, not a result of a inspection.

You have either not read the article or didn’t understand it. The PSÜ has little to do with the actual condition of the reactors.

I have read and understood the article. It is all speculation about what might or might not be necessary.
