Ah, sorry for the misunderstanding then.

Since I'm experimenting with nuclear reactors, I wanted to see how devastating a nuclear blast really is and what counter measurements I need to take (2 Layer Reinforced Stone? 3 Layer?)

The result was a save game with a nuclear test site, featuring two 6-chamber nuclear reactors (IC2) for controlled experiments.

Test Site A is located in a desert surrounding, simulating a "normal" environment.

Test Site B is located on a 48x48 stone cube to get repeatable results in a controlled area.

Both sites are monitored and switched on/off from a center control room.

For the lulz I did a test explosion with a fully filled 6 chamber reactor (quad cells):

I attached the save file in case others want to use it as well. I created it with Tekkit Lite, but it might work with other IC2 installations as well (not tested though).

Have fun!

As said before, he's playing on a server, Nether pumping would cause heavy problems, especially as no GregTech.

Actually, we already use that for our machines. We have a lava pump in the nether and use ender tanks to bring it to our area. We also run a miner with an ender tank. It's just that for the quarry we wanted to try something else, although geotherm would probably work as well.

Thanks a lot to both of you. It worked like a charm

I really appreciate the time you took to answer my questions so thoroughly.

I just finished testing the setup Omicron mentioned and it worked like a charm Thanks again for your efforts Omicron! That really helps a lot, not only for the reactor, but also for using gates and stuff

EDIT: Just noticed something: The reactor runs for as long as there are cells in it. However, is it possible to add an additional trigger? Thought: I would love to add an MFSU to the reactor (if he's not powering the quarry) and fill it. As soon as the MFSU is full, he should stop. But since the rector runs for as long as there are cells, that doesn't work. Also a lever does not work (as you mentioned in your description...)

I wondered if I can add an additional signal to the diamond pipe with the gate that I could trigger independently. Or could I lose the red wire and just power it manually? -> probably have to test that...

I can't say why the IIP is showing you 11 hours for runtime. 10,000 seconds should translate into roughly 2 hours 46 minutes 40 seconds.

Of course, you can test this. Let it run for an hour, observe how the number reported by the panel changes. Also check on the damage bar on the uranium cells inside the reactor, and see if they really expire in under 3 hours (and what the panel shows in the last few minutes before expiration).

I did run the test and it seems it's really because of the "cheated" uranium cell. I took some screenshots in case someone stumbles over this thread with the same phenomenon:

1. Overview: You can see that it still shows over 9 hours of running time...

2. Cells: You can see here that all cells are depleted equally, except one. My theory is, that this cell is kina invincible (I probably got them in a goofy way when I filled my inventory in creative mode):

3. Cell Description Normal: This is the detail of a normal cell (one of the 5 that is half depleted). The 6336 is counting up -> probably the seconds it's already in use.

4. Cell Description Cheated One: This is the dame detail of the "invincible" cell. Notice that the timer is negative.

=> Conclusion: The time is surely bugged (or cheated) and in a normal game mode would be as expected. Just for the lulz I will leave it running and see what happens once the 5 normal cells are depleted

Thank you Omicron very much. For the advice and to spell it out in a way even I can understand it :-))

I will test it first in a single player world before I go live though But I have noticed one thing that seems very strange: I have setup the reactor you mentioned and connected an MFSU. I also added an Information Panel. But strangely enough, the Panel shows me a running time of over 11 hours? How is that possible? Maybe because the Uranium is cheated?

Thanks a lot for the additional info.

But I wouldn't suggest a CRCS system for your first reactor. Look up some of the Mk. I reactors, the one producing 420 EU/t ought to suffice for your needs currently.

Yes.. and no For us part of the fun is the experimenting... if it really blows up, we'll recover from it. Or, in the worst case, reload a backup But the challenge to get it to running is the fun. But I agree that the basics are better learned in a "starter reactor" than a fully automated system

In addition, the reactor you mentioned would of course be sufficient. But then again, it's not. For us not the amount of output is the critical factor, it's the duration. For the quarry we need around 48 MJ to run a quarry at full speed. Taking the Conversion Ratio from the "Power Converters" mods this is about 120 EU/t. So even a very basic reactor is enough. BUT... it will only run for 2:46 hours, while the quarry needs much more time to dig (around 10 minutes per Layer, so by starting at Layer 70 we would need roughly 12 hours of energy).

I'm now thinking of just filling MFSU's and drain from there. But if my math is correct, not even a 6 chamber reactor can bring me the energy I need in one cycle. The Quarry needs roughly 50MJ/t. That is around 120 EU/t. For a running time of 12 hours I need roughly 105'000'000 EU. And even the biggest layout I found here "only" brings 84'000'000 EUs. So besides the 11 MFSU's I'd have to build I'm not getting the amount of energy I need What I could do, of course, is to build several reactors. 3 Mid Level 1's (from the official list here) would proabably be enough to fill the 11 MFSU's in one cycle. But that brings me into another dilemma.... the more efficient the reactor, the less Uranium I need, but the higher the building costs. So I could go for 5-6 very efficient small one and need tons of copper... or I go for 2-3 more unefficient ones where less copper is needed, but more uranium (which I have to refill again). I'll have to do some heavy calculations here :-))) (but again, this is part of the fun for us, so I'm not complaining)

Not sure what to do now.. another idea is to run it with a couple of Geothermal Generators where we pump in the lava directly from the nether. But a huge nuclear plant with 2 or 3 reactors sound like a great challenge as well.... And I just love the idea of a huge Monitor screen with tons of data running on it

Wow... just Wow.....

Thanks to both of you for that detailed answer. It's much more than I hoped A lot of the things are clearer now and I think I go with a semi-autmatic route with factorization (as that is included in my *nottobenamedmodpack* :-))

Thanks again.. it's really appreciated and I'm digging now more into the matter

Hi there,

I'm playing on a tekkit server with a friend and we are looking into building a nuclear reactor. We already build one on our old world but I basically just used a layout I found without really knowing the details WHAT I'm doing Now we are planning a bigger project and want to look into it a bit more detailed. But I already have a few questions where you might help me get on my tracks:

1.) All reactors I see have a running time of approx. 2:45 hours. Is there a way to make this longer? Or is it just the max the uranium cells hold? In other words: could I hava a reactor that runs 24/7 without the need to switch the cells 7 times a day but only once a day?

2.) If 1.) is not possible: With an infinite layout I can simply switch the cells, but can I do this only manually or automatically (with CompuCraft perhaps)? As I understand, the depleted cells could be replenished with a breeder. Could that be done automaticly as well?

3.) Is it possible to get a system running that, once it's setup, need no "new" materials like uranium at all? So like a closed cycle that takes the empty cells, refuels them, adds them in again?

I found a link to a huge setup with CompuCraft that does exactly what we need, but unfortunately it's for the old cooling design and would not work for us. But I guess it's somehow possible...

Our main goal is to run a 64x64 quarry with power from the reactor. And that means I need power for roughly 12 hours (if not more), so we would prefer a system with power 24/7, although we don't need excessive amount of EU/t.

Any helps or points into a direction is very much appreciated...
