Too much of U-235

[Maltsi]

Maybe i have missed something, but is there really no other way to get rid of this other than mass producing nukes? For now i've been loading a spidertron full of nukes and send it to fight biters, 99% of the case it gets destroyed accidentally, but at least it gets rid of that stuff.

I already have 64 nuclear reactors, but they only consume 14 fuel cells per minute, which is nothing.

Normally this wouldn't be really an issue, but i need the lower tier uranium for bullets (A LOT of them)

There is something you can do with uranium 235, it is nuclear fuel (not fuel cells for the reactors).
This is by far the best fuel in the game with 1.21GJ worth of energy.

Funny enough, even though it has a stack size of 1 it ends up to be the fuel with the highest energy value per stack as well (except uranium fuel cells but those are not really a "fuel" for machines and vehicles).
On top of that it multiplies the fuel value of a rocket fuel by 12.1 at the cost of a single piece of uranium 235, making it the most efficient fuel per unit of oil/coal used by a very large margin.

It also increases the vehicle acceleration from 180% (rocket fuel) to 250% (nearly doubling the boost), which is great for trains (and others) since it means that they reach their max speed faster.

Of course you might also want to pause your kovarex enrichment for now if you need more uranium 238.

Oh right, i forgot to mention that i do have nuclear fuel on everything that can use it. But as you said, it lasts really long time and doesn't really consume materials.

I knew i overlook something! Thank you, Already got some ideas how to only activate kovarex when actually needed.

Yeah harnessing the power of the logic network for Uranium is absolutely your best friend! Good luck!

P.S. Creating automatic refueling for my train network and watching it run is possibly my favorite thing in the game, so I can't wait to get back to that point in my game too haha

I am just wondering how you got into a situation where you have less U-238 than U-235 through initial Uranium ore processing (99.3% U-238 vs. 0.7% U-235).


As others have said, at least throttle or slow down Kovarex U-235 enrichment.

[Fel]

It can definitely happen, when you are not refining uranium ores (or barely) because you had plenty of uranium and no idea what to do with it, then left the enrichment running for several hours (possibly tens of hours even) and came back only to find that most of your 238 were transformed into 235.

It happened to me a few times so I'm not too surprised that it happens to some others as well.

I started uranium processing after i got kovarex, that was about 70h of playtime ago. So far i have only used U-235 that comes from kovarex processing because in my mind its wasted if you don't spend all of them on kovarex first, and this is how i got in my situation.

As of right now i made some circuit conditions to use kovarex production only if any of the following conditions is true
Nuclear fuel < 30
Nuclear fuel cell < 500
or
U-235 in provider chest < 100

This seems to work and doesn't halt my ammo production anymore

It takes an enormous amount of enrichment for it to go from 99.3% to 00.7% to 50% to 50%. Lesson learned.

It is possible that i made too much enrichment plants when i switched to nuclear fuel and nuclear power. My initial plants was not enough for non stop production, which obviously is not needed but at the moment looked like it was, because trains station were still filling up with the fuel. After those got filled then there was no need for that much anymore. Which i noticed probably 20h later when my walls started blowing up because there was no ammo.

[kremlin]

It takes one centrifuge and 3 three uranium miners to feed one reactor continuously, so it's really easy to overbuild the processing without realizing you are. Kovarex enrichment turns 238 into 235, it's only using the rest of the 235 as a catalyst and not consuming it. It's like holding it in a chest instead of making fuel cells. Sounds like you were so worried about wasting the 235 you need a trickle of that you wasted all your 238.

[puschit]

Had the same "problem" and just stopped with Kovarex at some point. I set up circuit logic to feed Kovarex again should my U-235 ever drop below a certain point but so far it didn't trigger and won't anytime soon.

Yeah, you really don't want to let Kovarex run non-stop without limits. Still surprising that you need a ton of uranium ammo at this point. Maybe consider using other turrets too?

I am using flamers too. I could probably add some artillery at the walls to completely remove attacks from all sides except one which due to ocean and my land layout cannot have artillery reach, already have shells automated and even delivered on the walls, ive just been lazy.

Flamers should be cutting down on the bullet consumption dramatically. With pre-space research they should be doing what, a minimum of 500 DPS per target? Probably closer to 2x that. Maybe take a look at the wall design? If it doesn't force the biters to alter their path to some extent, then flamethrowers have a hard time hitting the enemies in the front. Plus the longer travel time gives the flames more time to do damage. Another possibility would be moving the gun turrets back a few tiles. For example, directly behind the flamethrowers instead of directly in front.

Careful about artillery. It would reduce the pressure on the defenses in the long run, but in the meantime "revenge waves" will be severe.

I don't use dragonteeth or any other way to slow or redirect hordes so that would probably explain ammo usage. Its not really that bad, biters have no chance to even damage my walls, even behemoths dies in a split second. Entire wave is usually dead before flames reaches them so dragonteeth wouldnt help in my case.

My walls are like this, turret x4, flamer, turret x4, flamer (no spaces between them) and repeat for the entire length of the wall.

Flamers have close to twice the range of gun turrets, but without some kind of obstacle course they really can't reach their full potential. Still, even in your case you'll likely be grateful to have the flames if the artillery retaliation swarms start rolling in.
