Mark IV EB -- 120EU/t :: Continuous 4 Reactors Swap

Your math is off. If each reactor has a cooldown time of 120 minutes, you need FIVE reactors, not 4. Otherwise, the first reactor will still need 30 minutes to cooldown when the 4th is done.

You're still not doing it right. It runs for 1900 seconds, then cools down for 7600 seconds, so the total time for run+cooldown is (1900+7600)= 9500 seconds.

9500/1900 = 5 reactors. The cooldown time is in addition to the runtime!

Roughly speasking, each reactor runs for half an hour, then cools down for 2 hours. So, in 2 1/2 hours, each reactor can run only once. There are five half-hours in that span of time.

I hope I've made myself clearer - and perhaps spared you a catastrophic meltdown along the way.

surround the reactors with water, and run then at smaller interval say 1 min each

then you only need 4 reactors

hmm why no water its easy to do and improves your cooling by alot.

For me external water-cooling or not has boiled (pun intended) down to: if I require stability I can't rely on it. If I'm OK with over-cooling I can provision a safety factor and live with occasional evaporation.

Since I learned about the cascade water cooling system, I have no worries about evaporation any more. Basically, place the water source blocks 3 spaces up from the core (so they are just outside the 5x5x5 cube in which evaporation can occur). The falling water continues to cool the entire containment vessel, and since the source blocks are never evaporated they constantly replenish it.

As an additional safety factor, I've been using blocks above the reactor to get the water to fall in a ring, so I don't have to rely so much on water physics. I had a few problems with it not flowing into all of the spaces sometimes (esp. if using pistons to control the amount of water around the reactor).

This is ugly, but the total heating is 192 and the total cooling is 48. 192/4 = 48.

Design specs match the initial post. I recommend exploring designs that use 3x2 cells though, as they're slightly more uranium efficient. If you're using redpower2 you may as well go for a CASUC/CARUC solution instead.

funny pictures in that link XD

Interesting... I don't know how that got typoed; I didn't even know about those.

Here's the actual link: http://www.talonfiremage.pwp.b…=101k101001101521s1r11r10 (Note for anyone having seen my earlier post that the after ? is the same.)

Now that's more like it! (I had wondered what dinosaur costumes had to do with it)...

Your design would indeed allow for 4 reactors to be run more or less constantly in sequence, providing you have the means to set the timer. The cooldown is just 12 seconds longer than the full sequence would allow, so for full safety and constant operation you might want to have a 4-second off time when switching from one reactor to the next. I'm not sure of how much excess heat it would build up over the course of a full cycle otherwise - it may or may not matter.

This one is what I'd do if building this (which I wouldn't as I'd use a CASUC/CARUC design); it's 'only' 100eU/t but uses 1 less chamber per reactor and even had space for a small safety margin.

PS: The reason for the odd cooldown time on the other one is that it does not assume 'gated' operation but the maximum portion of a stable cycle. If run properly it will cool.

Unfortuantly i dont have screenies or able to get one as title says
i literally FILLED the entire reactor with Uranium Cells
and neatly stashed 3 Nukes underneath it
My Entire Epicly spawned Continent was eradicated
Biggest hole youl ever see
but i had to close it before the mass lag became too severe

Pretty sure anyone who's designed a CASUC reactor from scratch has done this.

Guilty. My open-desert CARUC reactor got out of line in breeder mode at least once before I realized the pressure plate was a bad input for 'heat up' and I think one other time when the filters by it grabbed the first few buckets (gee I now know you can use panels to partition tubes x.x).

That crater was... spectacular, lag inducing, hell. I think I probably took out about 30 layers of normal stone with it.

Yeah, I recall seeing a picture of the effects. The funniest thing wasn't the crater, it was the comments from people who believe that there's no way you could possibly have 54 uranium cells without using TMI.
I was like "wut WHAAAAAT"? I've accumulated twice that (not counting the ones I've already used for fuel), mostly from using the automated miner. I've found that there are, on average, about 3 uranium ore per chunk - but because they can spawn at just about any level, people who typically mine deep may miss many of them.
