[1.12.2] Very large fission reactors cause a lot of issues
Buggy123 opened this issue ยท 6 comments
In summary, extremely large fission reactors don't work well for a lot of different reasons. For reference, here's my reactor:
1: The maximum energy buffer of a reactor is about 1 million RF and the most energy it can output is that buffer every tick. However, a properly designed max-size reactor can produce 100 million RF/t or more.
2: Heat capacity has a similar issue. A reactor which doesn't produce any heat per tick is fine, but at these levels even a little bit of heat generation or a brief fluctuation in active coolant supply will cause a instantaneous meltdown.
3: If the RF/T and heat/t numbers are large enough, they overlap in the controller GUI, making them hard to read.
I'd recommend scaling the storage buffers to the reactor size, or otherwise giving players a way to expand them.
Everything on that list is fixed!
However, could I also ask how you managed to get the efficiency so high? 68000% is crazy :P
Ah, it's fairly simple actually. See, while testing I figured out that pretty much all passive coolers have far, far too little cooling to be useful in such a large reactor, and most of the actives weren't great either. However, the default cooling value for glowstone is five times as high as the next-highest liquid, 80,000 for glowstone vs 16,000 for liquid helium. So, I made a sort of cascading grid layout, and filled the entire reactor volume with it.
Anything with heat production much higher than Thorium produced far too much heat, but thorium oxide is just about right, and really efficient as well.
I haven't tried turning it on since the fix went out, so I'm not sure how much glowstone it'll require, but I think I'll manage. At worst, I might have to set up a dedicated ET void miner for it.
Oh wow, that is one of the most epic NC builds I've seen yet! You should be fine with the cooling - none of those numbers have changed. Hopefully the new version will fix your original issues :)
You know what, I found the issue - I made a slight mistake in the Fission Reactor code for calculating the effects of graphite. That's why the efficiency is effectively unbounded... oh well, I won't change it in case that wrecks some designs people have spent time on such as yours :P
Ha, thanks! I thought it was a little weird that efficiency increased exponentially as you add graphite. Now I just have to find a use for 100m RF/T!
