Fast Breeder Reactor is unbalanced

[Minoris]

As you all know, there are two fuel cycles in the reactor. The first burns the core fuel, the second enriches the blanket fuel. It seems that testing was not carried out for long periods of time, since these two cycles in any reactor power level (provided that the blanket fuel is replenishing in one way or another) add up one more unit of core fuel over a certain period of time. This causes the reactor to eventually shut down, as the refineries can no longer remove spent fuel because their outlet is blocked by this extra core fuel.

To solve this, you can simply use the Core Fuel that is produced by the Nuclear Reprocessing Plant as priority. You do not have to produce this extra core fuel that is introduced from enriching blanket fuel.

The wiki shows the proper steps to ensure no backup.

Prioritizing core fuel from a spent core fuel recycling factory is a logical step and you don't need a wiki to do that. But if you are forced to use the fact that the work of the enriched fuel processing plant periodically stops due to overflow of the core fuel, then this is 1) An attempt to externally balance the process. 2) Contradiction to the laws of physics. The reactor is not able to produce more fuel than it spends. If the balance spits on the law of conservation of energy, then it is necessary to correct the balance, and not to prop it up with crutches.

[Keranik]

The process in its entirety can produce more core fuel than it spends when you are enriching blanket fuel because you are converting enriched blanket fuel into core fuel. That does not mean conservation of energy is thrown out of the window.

It is indeed an intended feature and how such reactors work in real life. Don't think of it as creating nuclear fuel for free; all these reactors do is take non-fissile materials and bombard them with neutrons until they're fissile. The energy released when the new fuel undergoes fission was paid by a star a long time ago; all the reactor did was add neutrons to the atoms until they were finally unstable and that energy could be accessed.

It's the same thing as puffing up a marshmellow.

Make your reactor output pipes long enough and use your balancers the right way = no problem with stuttering. I have a fast breeder since ~400 years and no problems with getting stuck.

[Kaery]

As Synical noted, that's how this reactor works. That's why it's actually called a 'breeder' reactor.

Basically, when you get higher into nuclear physics, stuff can get strange.

i always have an extra reactor that just uses the excess fuel

2 breeders and the excess goes into the 3 reactor and uses that.

So your 3rd reator isnt running anytime or you waste resources.

Because there is no exess. After the reactor has enough core fuel it will run without corefuel from enriched uranium and didnt produces exess of enriched blanket fuel. You have to produce only small amounts of empty blanked fuel and convert enriched blanket fuel to core fuel and renewed blanked fuel.

Enriched blanket fuel will not cause the reactor to shut down if the output buffer fills up. It's like eggs in a chicken farm. Pull it out if you need it to make new blanket fuel or core fuel, otherwise, just let it sit in the reactors.

i dont need the 3rd reactor. except to burn off the excess fuel from the breeders. when the third one burns one fuel, the other reactors will not run at full capacity and throtle down.
this way i can just let it run, i still use depleted uranium, still have 5 big storages full of it.

the system runs over 1000 years already lol

are you saying i dont need to burn off the excess fuel? in the previous version, update 1, the reactor would stop because of the excess fuel, or i messed up and play id wrong ever since lol

oh lol, it seems i have been doing it wrong, the excess fuel is no problem.... will try a new setup

Yep, perfectly happy with full enriched fuel buffer:

but the problem is the recycling, its buffer will be full?
