Your document shows 10.9 ct/kWh normalised production cost for 2025 (roughly double the ~5 ct of a normal year, because the plant was offline half the year). That shows how exposed such a plant is when it's offline; and running an existing, paid-off plant built in the 1970s, like the one you linked, is a very different thing from building a new one today.

Burning coal sure is stupid, but so is being stuck in the outdated idea that we need either coal or nuclear for baseload. Solar, wind and storage are much cheaper, more flexible and far faster to build (a year or two, not 15+). IMO that's a much better answer than starting some SMR pipe dream now. 10 or 20 years ago it would have been different, but there's no point clinging to a solution just because it made sense back then, and was rejected for the wrong reasons.
