From what I see the only means to get rid of the steam is to use an engine or turbine, but the grid keeps shutting them down during over production of electricity. What is needed is a condenser to convert it into water or an evaporation tower.

The insane amounts of excess products in this mod is honestly annoying and off-the-scale.

Steam and deuterium-depleted water just piles up endlessly, without any proper way to dispose of them. Sure, there's a pump that deletes the water, but when you need 44!!! oil refineries to run even a single machine making heavy water, that's 44k of dd-water being produced PER SECOND, requiring a pump per refinery. You essentially have to cheat and use waterfill to put the pump directly on the refinery. There are no pipes that can handle that insane flow.

All in all, I like the idea of this mod, but it's completely out of whack on just about every scale. It also handles heat energy as an item (MJ and GJ) which is just weird.

If playing the Advanced game (which is the default setting), it takes three vanilla turbines to use up the waste steam from one electric boiler. Or, in my case, I use 3 of the high-capacity turbines to use up the waste steam from 10 electric boilers. In both cases, you do get a bit of power from the turbines but never 100% because (I think) steam like from nuclear is at 500C but the waste steam is only 100C. My grid does not shut down these turbines in my game...keep in mind that there is a setting in this mod (under the Startup tab) that can change the priority system of which turbines will stop when the base load decreases.

Yeah, there can be a lot of depleted water and yes you can need a bunch of pumps but no, you don't need the Waterfill mod. Just build on top of a landfilled lake...many players do this already with their vanilla nuclear sites. It might be handy to use a less cheaty landfill mod like Simple Landfill Mining so that you can fix landfill mistakes. The pictures that are shown under the Information tab are examples of what an RFP site can look like. It's what I used for my own game, and it balances just fine when you finally have all the top techs.
