SMRs 1) don't exist 2) aren't affordable even if you believe that projected costs will not increase in opposition to hundreds of prior cases where they did 3) still need a giant containment building which is going to involve knocking down most of your coal plant or routing steam awkwardly (losing heat and increasing costs) and 4) produce lower temperature steam at lower head than a coal burner so there's no evidence they'll even work properly without replacing or massively retrofitting the few remaining components. Using them as thermal batteries might work though. No need to keep them on for any of the above. Just mothball them. This does nicely reveal the actual goal of all the nuclear "advocacy" though.

  Adding even more moving parts and maintenance costs will definitely solve it. Yes. And naval reactors definitely are the cheap, simple energy source of the future. This is why noone has built anything else since the 50s. A non-modular demo scale pebble bed reactor also ain't it. But you've already revealed your hand with that comment about continuing to burn coal juust in case it's not vaporware, so why are you still bothering to pretend it was about fantasy nuclear reactors?
