aside from crafting the reactor components, there isnt much complexity to this mod, and doesn't explin much about how a reactor works. maybe in stead of just building the power plant directly, the machines could all be replaced by a reactor that crafts water into massive amounts of high-pressure steam, followed by a chemical reactor recipe to turn supercritical steam and water into lots of steam.

I imagine this would go against the goal of minimizing the UPS impact, last I was aware, steam is what kills UPS with the existing nuclear setup.

Bingo. If it weren't for that, I'd have made the reactor hall, turbine hall, and cooling all modular.
