Hey guys. I have the Mindcrack mod pack on my server and I've noticed that Nuclear reactors really suck. I built one and spent lots of materials on it and about 12 dual uranium cells (24 uranium) is only able to produce about 4 UU matter. Is there a value I can edit in my configs to quadtruple the energy output of nuclear reactors?

Yes, you can edit the value of the nuclear reactor very easily in the ic2 config file. However, the problem with the nuclear reactor not giving enough power has to do with the matterfabricator rather than the reactor. The matterfab requires insane amounts of energy to produce 1 UU matter. I currently feed it with 1024 EU/t (2 MFSU's) and it still takes over 5 minutes to produce 1 piece of UU. I think you'd rather change up the amount of energy the matterfab needs to produce 1 UU matter. You do that in the Gregtech config file. If you change the 16666666 to 1666666 (basically remove the last "6"), your matterfab will create UU-matter like a mass fab would (keep in mind, the matterfab still requires scrap to function). So you get 10 times more UU matter from your matterfab-nuclear reactor setup.

Keep also in mind that changing configs on a server may cause mismatches between server and client configs and render players unable to do certain things, so make sure the players on the server change the config settings as well (not sure how changing energy consumption would do that, but nonetheless always a good thing to do).

VANtheSven: check your math, the GregTech matter fabricator on default settings needs 100 times (two digits) the energy of the regular IC2 mass fab, not 10.

Warnipple: your problem is that you are playing in a GregTech environment, but you're not using GregTech to build your reactor. The mod adds quite a few options for highly efficient designs. Here's one of the best.

- Will breed its own fuel after initial startup
- Comparable EU/t, five times the total EU output per cycle of yours
- Cost per cycle: 5 uranium, 20 copper, 40 coal dust. Your current design: 24 uranium, 96 copper, 0 coal dust

Quoting from the Gregtech wiki: "Here are a few Features of special Blocks/Items MatterFabricator EU consumption rate can be adjusted. Regular MassFab rate=1666666(just remove a 6)"
Doing my math: 16666666/1666666 equals ±10, not the 100 you are talking about.

Just because a wiki says it doesn't mean it's correct...

Let's add some separators:

IC2 Mass Fabricator without scrap: 1,000,000 EU
IC2 Mass Fabricator with scrap: 166,666 EU
GregTech Matter Fabricator without scrap: (will not run)
GregTech Matter Fabricator with scrap: 16,666,666 EU

My mistake, you are right. It seems that either Greg is lying to us or it is just a typo on the Gregtech wiki. Still my math was right though, but my information wasnt. In that case remove the last 2 sixes to have a mass-fab rate of uu-production (and 100 times the output of the "standard" matterfab). And using the mass fab without scrap is a waste of energy imo, especially when using nuclear energy.

Yes just goes in the IC2 config and change the BaseNuclearReactorOutput=5 to whatever you like I made it BaseNuclearReactorOutput=100 on my server.

This is what I did but I changed it to 50 instead of 5.

24 uranium produced about 43 UU matter. I may change it to 200 if this is not sufficient. Also I hope my players won't have to change their files for this change.

That produces 1,000,000 eu at 5 eu/t. Multiply that by 40: 40,000,000 eu at 200 eu/t. 200 eu/t is very, VERY strong, considering you have one (very easy to find) reactor. And this is the most simple setup, you need 1 vent, 1 cell, and the base block. The amount of UU matter you're getting from one uranium cell is a lot. I'd just watch out for balance issues, there's no reason for anything stronger than this, unless you want...this: 30 lapis, 2000 eu/t and 400 million EU. http://two66.com/reactorplanner.htm...v6h9ptfpt3778pizifsu407j6mr8lenqs72u0w8bp2fi8
And those are weak reactors that takes someone 10 seconds of thinking.

Yeah... 40 times base output, that is a little silly. It's going to make a few of the better designs near impossible to build - for example, the linked hybrid reactor would produce almost 15,000 EU/t, which means you'd need to connect 8 HV transformers just to be able to even accept the energy output without instantly detonating your whole base.

Considering how powerful properly build reactors get, I'd advocate no more than a doubling in energy output.

I'd say double is near the perfect balance. As you than can produce more EU than the highest Solar Panel tiers can. But not so much that it become ridiculous.

He only made it 10x the output Not 40x!! I don't even have it that high, as my server is only buffered to 20x output.

Actually even with 10x it's still pretty OP (esp. if you use the GT hybrid nuclear set up).

Yea 200x is really just plain stupid and will make All design a crazy positive feedback loop even with LZH condsators. So just don't goes crazy on buffering it to that extreme.

Still less than half as efficient as the hybrid reactor linked further up.

Face it guys, until 1.5.1 changes the way GregTech plutonium works, you're not going to beat that design's combination of extreme utility and efficiency rolled into one. :p

I thought that Throium is the only thing changing the lifespan to only half then what's is now. So how is the plutonium is going to change too?
