attatched is a .schematic of my version. i didn't realize other people had been doing this, so its called G.lass's A.lternative C.ooling S.ystem, thus the file name. Mine never ever blows up upon even rigorous unloading and reloading, because it fits entirely in one chunk. in fact, it can fit 4 into one chunk horizontally, and up to 60 if you put them vertically (although that dimension can probably be made slightly more compact). It does 640 EU/t, and can probably do more, but I prefer to leave the buckets in the top just in case. It uses 2 deployers, each with a 2x3 pool in front of them, because after much testing, my personal findings were that deployers can in fact go faster than water if on a .4 timer. It also uses 2 filters emptying the chest, and one tube leading to it from the reservoir chest, which has 2 filters hooked up to it as well. The chest also allows for a large buffer, I don't know if you guys had that. Also, if yours fit exactly into one chunk and still was blowing up with the unloading/reloading thing, it may have been the water. water doesn't reupdate upon reloading, so it needs redstone/redwire powering a block directly next to it. My design already had that, so I never experienced it in the first place, but just something you should check.
There are improvements to be made though. I probably do not need as many transposers sucking out excess as I have running, but I wanted to be sure. The main improvement that could probably be made is to put a delay on the extraction filters, so that the empty buckets are pulled out just before full ones are shoved in, so that they aren't ever in the way, because then they wouldn't be going at the same time. Still I don't see how we'll ever be able to get more than 1250 heat per tick safely working with more than 3 added chambers, as 1 filter can only handle extracting 2.5 buckets per second, and even then, I don't think RP time and IC heat ticks always coincide that perfectly, so it would probably have to be slightly less than 1250 heat to be safe.
Also, I don't know what you guys' systems are like, but reloading mine is a piece of cake thanks to the reservoir in the chest. all you do is put the uranium in, and switch out the second row of water where needed (it will fill up without the uranium in the way). then, put the water back in the system at some point in time, but it doesn't really matter when as long as its before the next cycle. with all the transposers i have running to get the extra buckets, i just throw them in a hole in the glass near them, although in the schematic i gave you I don't remember if the hole is there, or if there's any extra glass. I have two schematics, one with some reinforced glass protecting things just in case, and the other with it stripped away. I don't know quite how robust you guys' are, but mine is good enough to handle random items being thrown in the reservoir accidentally, along with buckets of lava about every couple seconds. You can know when its fully ready for another bucket of lava when the three buckets of water reappear full in the top right corner. If you do throw lava in for shits and giggles though, make sure to leave the bucket of water you get from it in your inventory, as throwing too many in can add up over time to too much being in the system.
With allocators, it should be possible to make it much faster, as allocators can fire up to 5 time per second (more using the torch trick). I don't know if the torch trick can be used though because it would probably shut down the reactor. Still, that would amount to quite the improvemet per missing chamber, and would basically double the potential heat.
Edit: be sure to turn on the cooling system (switch at the bottom) before turning on the reactor. Also, here's the layout inside if you're too lazy to use the schematic: http://test.vendaria.net/index…UXUUUUUXXXXXXXXXXXXXXXXXX
Also, I've been testing with the top row partially full of uranium. so far, 3 has blown up upon rigorous loading and unloading. I may continue testing 2 and 1 (if 2 doesn't work), but I'd rather leave it be for now, because its already at a very convenient 640 EU/t, which is exactly 1 high voltage + 1 medium. (512+128).
They're more to increase the energy storage of a MFE. Also you need to charge/discharge energy/lapotron crystals manually, whereas Electrolyzers will store energy when it's not being used, then send it when it needs it. [But still basically just used to increase the storage on a MFE (if anyone uses 
If you come up with anything else for me to test that may be a problem, let me know. Otherwise, I'll get to working on it legit and a way to use all that energy so it doesn't go to waste. I hate MF'ing without the proper amount of scrap, you wind up using almost 10 times the energy, and since uranium is now a finite resource (since they took out the uu-recipe), I'd rather not waste mine, even in an extremely efficient reactor.
had a stack of 64000 buckets in a few seconds... :P)
