Well, there is Scram.
It's a historical nuclear reactor simulator released in 1981 and influenced by the Three Mile Island accident of 1979.
You can emulate it on Linux.
The developer doesn't consider it fun, but it was endorsed by Director of the Office of Nuclear Reactor Regulation Harold Denton.
Rimatomics is a mod for the strategy/base builder game Rimworld, adding nuclear reactors and real-world/fictional nuclear powered weapons. You can build your own reactor designs by connecting cores to heating and cooling lines, the heating line to a turbine and then a turbine into a power generator. The challenge comes less from meticulously managing the reactor, and more from protecting it during raids and disruptive events. It's not really a "study sim" so much as it's a satisfyingly complete nuclear reactor conversion mod, but I've had a few reactor-focused playthroughs that are very satisfying.
I've played probably a hundred hours with this mod on Linux and it's quite good. Your enjoyment will probably depend on whether the base game of Rimworld appeals to you though.
Then, you have Mindustry and its thorium reactors. IIRC, they don't need to be connected to turbines like in Factorio to generate power, however bad things (TM) happen if they are destroyed or if their coolant supply is disrupted...

I know Rimworld and love it! I assume the mod is somehow similar to nuclear power management in Factorio?
