QuoteYou can use thermal monitors + not gate. So it will emit a redstone signal when reactor is cooler then specified heat level.
Yes, that's true. But,
QuoteYou can use this signal to stop cooling.
How, without mod "Redpower 2"?
That's why i was asking about your mod. It can be considered "part of Nuclear controlling" to be able to stop the cooling of a reactor - whatever the cost could be. So, asking if you could add a way to do it, or not. 
Hello,
as of part of your excellent mod, would you consider adding a feature so we could stop the COOLING of a reactor?
Again, thank you a lot for your help. Now i have a choice to make; be dependent on another mod or not...
It's all clear to me now.
"External lava" should be explained in the wiki, by the way.
And i have no idea if fire is doing anything (just stopping the "air bloc" to be counted?), but it never happens with me.
The idea would totally work, but i don't know how to automatically remove any component of the reactor. You're using another mod than industrial craft?
I don't get either your "start timer".
As i got the pistons only pushing blocs & letting lava go on when the uranium cell is gone, you can guess i know a bit about redstone and detector cable 
But i'm not using any mod permitting me to automatically remove a component from the reactor. I'd be glad to know one.
Thanks a lot for all those answers.
And I assume the answer to my question "Do you know, by the way, if i was right to suppose that 1 opaque bloc = exactly 0 cooling?" was "yes".
So, i have absolutely no way to get around those 36 internal cooling...
If i understand you correctly, the numbers are those (considering the new piston-mechanism i just made) :
WITH Uranium : 20 air,
18 external cooling (13 by reactor&chambers + 5 by air),
36 internal,
heat : 54
TOTAL = 0
WITHOUT uranium, with 4 depleted : 5 lava, 11 air, 4 blocs
0 external cooling (13 by reactor&chambers + 2 by air - 5*3 by lava)
36 internal,
heat : 4
TOTAL = 32 cooling / second
WITHOUT uranium, with 5 depleted : 5 lava, 11 air, 5 blocs
0 external cooling (13 by reactor&chambers + 2 by air - 5*3 by lava)
36 internal,
heat : 5
TOTAL = 31 cooling / second
Ooooh, right! Thank you.
Got another question i can't find the answer on;
external lava is diminishing external cooling to a minimum of 0, or ALL cooling (internal too)?
Oh, you had 4 air around it? I see 1 on your image, at least.
Do you know, by the way, if i was right to suppose that 1 opaque bloc = exactly 0 cooling? As i cannot trust the "planner" on everything.
edited : you edited & answered.
Damn, how am i gonna do... 1 lava bucket every 33 minutes means a lot of lava buckets in several days.
Oh my...
So, i have no solution, as i cannot anticipate an uranium cell disappearing OR becoming a near-depleted cell...
By the way, why are your 5 near-depleted cells only producing 4 heat per second in total instead of 5?
edit : If i create a redstone input on a reactor chamber, and this input is put to "on" when the reactor isn't producing any EU, will stopping the reactor that way stop any heat production too?

<NewMilenium>: No idea?
<voker57>: without uranium cells, reactor doesn't generate heat
<NewMilenium>: ahh
<NewMilenium>: thank you.
<NewMilenium>: even with Re-Enriched Uranium Cells, right, as long as there's no uranium cell?
<voker57>: yes
<NewMilenium>: thank you. As i thought, raGan isn't answering me at all, but pretends to - twice...
<Cassandra>: ah I got stopped up doing other stuff but voker is right
Big thanks to voker57 and Cassandra.
So, raGan, this answer enlightens that even a near-depleted uranium cell created by an uranium cell that ended in the breeder won't produce heat, contrary to what you said.
I'm sorry to have to say it, but you're not answering at all my question;
i totally noticed cooling applies all the time (otherwise "cooldown" would have no meaning in nuclear engineering), my question is about this Re-Enriched Uranium Cell; does it still produce heat when NO uranium cell
is in the reactor?
Because my automated heating system for my breeder seems not to be enough to maintain the heat when the calculation takes in count the four Re-Enriched Uranium Cells.
Having those 4 heat/tick going in the hull or not doesn't count much to me, as i am supposed to have exactly the same cooling value (4/tick). Here are the designs;
the breeder,
the breeder when uranium cell is gone (thanks to pistons - the 4 "unused blocks" are reinforced stones in my case).
Hello,
i'm using your thread because i'm going to precisely ask a noob breeder-related question;
it is written here :
Re-Enriched Uranium Cell
QuoteThe fully charged state of an isotope cell, it will continue to produce only 1 heat and no EU but it will no longer react with adjacent Uranium Cells. Combined with another coal dust, it will become a brand new Uranium Cell.
Does that 1 heat per tick happens when there is NO strictly-named "uranium cell"?? Because it seems it isn't happening.
Slowly going to the conclusion than a reactor cannot generate heat without any strictly-named "uranium cell".
(i did a breeder with automated pistons pushing blocs and liberating lava to maintain the heat when it stopped, and... it's still losing heat. I counted the 4 Re-Enriched Uranium Cells as "1 heat / tick", but if it's not the case, i must permit lava to be near the reactor 1 block more...)
