Nuclear reactor help

[lifeseeker128]

I'm using the FTB Ulimate pack with some modified configs and I'm trying to set up a nuclear reactor for my Mass Fabricator. I got everything together for this set up: http://www.talonfiremage.pwp.blueyo...4ek6cxhbsejd7ptefnlwen3l6d7363eh17qs8jm5hws8w

I placed down a HV-Transformer and an MFSU to catch the power and a 4xins. HV Cable to connect the reactor with them. When I use a lever or toggle latch to turn the reactor on... the cable melts and when I connect the transformer up directly, it blows up. I tried using glass fiber cable too with the same result. What's wrong with this set up? I replicated this within a test world without the server I use, and I get the same thing. It looks pretty and the insides are arranged to that exact design, but I just can't get the power out of it.

I don't know much about how the reactors are supposed to work in this mod pack, but I've done everything the wiki told me here at the bottom: http://ftbwiki.org/Nuclear_Reactor

My configs may have changed, but I've looked and found no options within them that would help tone down heat or voltage to prevent cables from melting and machines from blowing up. Please help me figure out what's wrong?

Which way is the transformer facing.

It should be [reactor] -> [MFSU] -> [MVside / HVside] -> Matter fab

 

[lifeseeker128]

I have it [reactor] > [HV cable] > [HV tran, 3-dot side/1-dot side] > [MFSU, 1-dot side/3-dot side] > Mass fab (I re-enabled it)

All this is just how it's connected and the cable will melt immediately after turning it on.

Strange, can the MFSU handle EV now? From my experiments, it can't in my mod pack.

Another thing I found, the cabling won't melt and reactor will stay stable when I use only dual-uranium cells, but when going back to quad it happens again.

 

[namiasdf]

You don't need the HV cable unless the reactor outputs HV.

[reactor] ----fibre----> MFSU -----> mass fab

What is the size of the EU packets traveling from your reactors? The only reason why they'd be melting is because you're exceeding HV. 4x insulated cannot carry EV, only super conductors can.

 

[lifeseeker128]

I'd assume the packets are EV because of the melting, but it seems putting in weaker uranium cells bumps it down to HV just fine; even though the guy in the one vid on that wiki page showed only quad cells in the reactor he built (and only used glass fibre cable to bring up the power), I don't think it matters much in my set up. Although, there's my testing of the HV Transformer. The thing just blows up as soon as I hook up the 3-dot side to the reactor. It seems the voltage limit on 4x cable isn't the only thing that's changed in IC2 since I played it in Tekkit @_@. Or could this just be GregTech's trickery? Guess the guy just wants us who use his mod to use his super wires for the extreme stuff and nothing old or easy. Thank goodness he left much of the settings to the config files.

huh.
HV transformers can handle EV when downtransforming.
MFSUs can handle HV input.

you should be able to wire straight into the MFSU. dont use HV transformers at all.
everything worked fine for me when i duplicated your reactor and put an MFSU right on it.

look around though, theres a lot better setups all over these forums.

 

[lifeseeker128]

Hmm... actually, I just tested my HV transformer again on the reactor and it works just fine for safeguarding the voltage to the MFSU. Still though, my game seems to want the direct MFSU or cable to blow up or melt respectively with quad cells inside. Strange bugs/configs on my game, perhaps?

That reactor outputs 320 EU/t. All generators, including nuclear reactors, output one packet a tick with the same packet size as their output rating. In this case, 320 EU per packet. Neither glass fiber cables (512 EU/p) nor HV cables (2048 EU/p) should melt with that output.

However, you state that you're using custom configs. It's possible in the IC2 config to raise the output base of nuclear reactors, which then obviously increases the total output rating of a finished reactor above what the reactor planner shows. If you raised it too much, your reactor might simply output so much EU/t and EU/p that any cable just melts.

Can you tell us what the following line in your \minecraft\config\IC2.cfg looks like? This would be the default setting:

I:energyGeneratorNuclear=5

 

[eric167]

use an EU-reader, it will give the EU/t of the cable. since the reactors output 1 X sized packet per tick, it also tells you packet size.
that will give you a precise output number.

You can't measure a cable that melts the moment you flip the lever...

 

[lifeseeker128]

lol it's 50!

There's my problem, thanks for telling me the line to look for. Apparently this one "Universal FTB Config Pack" hikes all the generator values up. Will my other settings cause problems using other generators? Cause I haven't experienced any with them at all. Also, how would I alter this setting in order to have EV (2048 EU packet size) cables be able to work again? My settings are:

    I:energyGeneratorBase=10
    I:energyGeneratorGeo=20
    I:energyGeneratorNuclear=50
    I:energyGeneratorSolar=100
    I:energyGeneratorWater=100
    I:energyGeneratorWind=100

Guess this is the price I pay for using easy mode configs; information's not always accurate for my own play time and everything isn't guaranteed or tested to work perfectly as expected.

Edit: I took eric's advice and hit the HV tran with an EU reader. Says the input is 2048 and the same output. It said exactly, "Measured power [EU/t]: 2048 in 2048 out 0 gain (avg. over 36 ticks)". This is with an HV cable connected to an output with the other end in an MFSU. I've also tried connecting the MFSU directly to one of the HV tran's outputs with no explosion. Why is this? Isn't an MFSU supposed to only accept HV, not EV? More strange configuring?

The other values are all default. However, nuclear reactors are 10 times as high as normal. As a result, the reactor does not generate 320 EU/t... instead, it generates 3200 EU/t. No wonder even HV cable melts, and anything you connect blows up! There is nothing in base IC2 that is designed for that kind of packet size.

If you want to know what the number in the config means: reactor output is a sum over all (indicidual uranium cell * its efficiency * base), where "base" is the number in the config. In your reactor, this is easy to compute since all cells run at exactly the same efficiency, namely 4, so you can just multiply instead of summing individual terms: 16 cells * efficiency 4 * base 5 = 320. That's what the reactor planner tells you. But since your base is 50, the end result is 3200 instead.
