Just a question to see if this would work...

add another chamber for no cooldown time whatsoever

Like the person above me said, you could add another chamber to make it a MkI reactor, so you can run it infinitly. Just keep in mind that you probably don't have the full 24 blocks of water, so keep that in mind.

I beg to differ, a MK II EC is AS GOOD AS a MK-I because you will never be at the reactor just as it depletes. (Unless you have a timer that makes you return just as it does.) In which case he would have to do that for 24 consecutive cycles and refill it in 0 seconds...
He would have to keep that up for 2.7 days non stop to make that reactor go boom. And with the (soon to be updated if not already) thermometer addon he can check to make sure the reactor is at 0 heat before he reloads it.
Either way, that reactor IS safe and you don't need to make it a MK I, just give it some time to cool. That is, if you notice it has stopped producing power then give it at least 4 minutes before you refill it. But like i said, you can mess up 24 times in total over a period of 2.7 days before you make an explosion happen. If you think you have messed up 23 times in a row then let it rest for 92 minutes. (1.5 hours) and you are good to go again.

Hey guys, I've never done a reactor. I think I've just designed one on talon that would work wonderfully though.

I think you didn't design that... it's Rick's "budget upgrade" reactor from his sig. Identical in every regard.

Don't get me wrong, it's a great reactor design... but it's not yours. Was done long ago.

Safety is one thing, but eff is quite another. This is my design http://www.talonfiremage.pwp.b…=1o10101001501521s1r11r10 (only 10 less eu/t) and I forget who's it is but here's the other http://www.talonfiremage.pwp.b…=1o10101001501521s1r11r10 .

However if you have RP2 or feel like 'the redstone one' you can build a far higher efficiency reactor for way less resources http://forum.industrial-craft.…page=Thread&threadID=3189 Two or three single cores in their own water enclosures hooked up to a 1 second out of 16 pulse will give you a /lot/ more power over a much longer time for your uranium.
