The problem with reusing coal turbines isn’t that they couldn’t work, but that you would have to engineer everything backwards from the turbines to the reactor. You COULD do that, but really, you should be engineering to what the current projections for the power needs to be, not the projected power needs from when the coal plant was built.

Maybe reusing the coal plant site makes sense, but only if the coal plant was already taken offline, which to be fair, a lot of plants are being taken offline.
