This mod is a tweak upon a brilliant "Realistic Reactors" mod. The goals are:

1. to have the reactors react more smoothly to temperature changes

   • there is a noticeable jump in reactor performance once temperature reaches 500 degrees. This irritated me a lot especially since I was trying to shutdown the reactor automatically to save fuel. This strategy doesn't work, but it is still irritating to see instantaneous changes of thermal power.
   • the power and efficiency charts are also made of straight lines in RR. I prefer smooth curves. The RRForK2 uses splines to achive that.

2. to extend the fun into higher temperatures

   • regular RealisticReactors mod provides little incentives to run your reactors hot. Yes - you can do it, but usually you don't need to. It's much easier to set up an alarm if your reactor temperature goes over 800 degrees and may be even automatic shutdown.

3. Make different reactor types shine at what they are designed for and discourage abuse

   • For me the typical gameplay was: once breeders researched - upgrade my reactors to breeders; once breeder fuel cells researched - use them instead of regular fuel cells. With this mod you have pros and cons - you don't only get benefits, but there are downsides with each such "upgrade" too

4. to allow getting the "Fusion is for men" Krastorio 2 achievement

   • Krastorio 2 has a Fusion reactor, which requires Deuterium, which requires U-235. As I understood, K2 buffed the Kovarex cycle about 4 times to allow you to produce enough fusion fuel to power up the Intergalactic Tranceiver. I don't think RealisticReactors has such a feature and therefore you have either to stockpile U-235 or run tens and tens of breeders. With my tweaks it becomes possible to have just 1 breeder per Fusion reactor (but only barely).

So it is a different mod to RealisticReactors?

This mod is currently considered to be a test drive - I hope to eventually deprecate it and incorporate the changes into the upstream mods (RR, NF and K2).

So what's different, exactly?

1. Reactors will be less powerful at lower temperatures. Usually that's what you want anyways at early stages of the game
2. The sweet spot might be at different temperatures than in the original mod. It also depends on how many reactors you have.
3. It makes less sense to use regular reactors as breeders and breeders as regulars than in original mod (that's something that bugged me a lot).

Usage outside of "Fusion is for men" scenario.

If you don't need loads and loads of U-235 - you'll probably find this mod very similar to the original RealisticReactors. That includes reactor cooling. In fact the two mods are not very different in that because maximum thermal power of the reactors is about the same.

How to switch to this mod from Realistic Reactors

Unfortunately, this is a bit tedious.
1. Read all these instructions first
2. Shut down all your reactors
3. Demolish all your reactors
4. Save your game (a different name is recommended)
5. Install the mod
6. Load the save WITHOUT syncing the mods
7. Go to the "settings" -> "mod settings" and select "Krastorio 2 targeted formulas". Otherwise you'll experience the same functionality as before.
8. Go to the "settings" -> "mod settings" and select "classic" as fuel cycle for Nuclear Fuel mod.
9. Rebuild and restart your reactors.
10. Demolish and rebuild your cooling towers. This will restore animations.

How to switch back.

Step 7 above should be enough to bring you back to old mechanics - just select "Ingo's formulas" or "Ownly's formulas" instead.
