But I've hit a problem with figuring out how much steel to use. The mod is a refresh of nuclear power. Specifically, it will make it far less UPS intensive, while moving much of the complexity of building nuclear to the assembly phase, rather than the layout phase. But it will have a lot of intermediate products that are actual things you need to build a nuclear reactor (steam generators, switchgear, turbine hall, etc). To build 500 MWe in Factorio, you need

A (real world - circa 1970) 1 GW nuclear reactor is going to use around 36,000 metric tons of steel https://web.archive.org/web/20060316092 ... _8=051.pdf (if you were curious). But how much is one unit of steel in Factorio? Or even of iron? I tried calculating it and I got that one unit of steel was somewhere between 16 and 258kg. Not exactly a reasonable range. And it's fairly obvious that one 'unit' of a thing in factorio does not mean they have equivalent mass or volume. 1 unit of concrete is one square meter (because it fills one grid square in game, and each grid square is stated to be around 1 meter by the devs).
So I guess I'm asking, how would you go about balancing this mod? I want it to be a challenge to build because actual nuclear reactors are not at all simple things to construct (I've visited them, and seen the blueprints the engineers work on when replacing and repairing pipes). But I also don't want it to be so massive of a resource sink that people say "Well screw that." because it seems unreasonable. I do feel like 75000 units of concrete is reasonable (no it won't all be one blueprint, there will be intermediates). But how much steel should I use? 36k? 50k? 75k? 150k? More? Ahh!
