Okay i have a Problem in Stoneblock 4 i build my Reactor in a compact machine and the machine doesnt have enough Place to Build the SPS in it to so i would need to rebuild the reactor can i get the Polonium or Nuclear waste out of the Compact machine? HELP

Usually moving waste through dimensions is a no go there might be something you can do using the applied energetics mod but spacing is a problem so you might just have to take it down and rebuild I'd suggest first emptying the waste into the barrel before you create radiation all over the dimension

if you're still looking for ways to transport it, the best way I can think to transport it is using AE2 using the Quantum Rings. Set up a few storage busses that are pointing into the top/bottom of some waste barrels, then set up a Quantum Ring system to send it through your AE2 system, storing it in those barrels. If you don't know how to do that, there's a quest in the storage tab to teach you about it. Once you have it out and can use the waste to make polonium and plutonium, I recommend making some MEGA Radioactive storage cells. They let you store up to 1024 buckets of a given radioactive material for crafting purposes, be it waste, polonium, plutonium, or even spent waste if you want that for some reason (I needed a cell for it so I could transport it to my disposal site)

Spent Nuclear Waste - Official Mekanism Wiki

Spent Nuclear Waste is one of the final products of the Fissile Reaction. It is created as a by-product from producing Polonium Pellets and Plutonium Pellets. It is radioactive and the only known way to dispose of it is to dump it into Radioactive Waste Barrels, where it will slowly decay.

Anyone have tips to get more nuclear waste? Like I’m struggling to get enough for everything to get to antimatter. Like I’m just trying to get enough for the chicken but I need so much polonium and plutonium.

Any tips? I tried making my fission reactor bigger but then I couldn’t keep up with water for coolant. I then tried sodium but I don’t make it fast enough?

Maybe I’m just not seeing the way or something.

Use ae2 extended IO port + water cell for coolant

I built a 9x9x9 fission reactor in a compact machine with a turbine next to it. I wasn't gonna bother with a turbine since I set up a mycelial reactor, but it fully recycles the steam from the fission reactor back into water. As a result, it doesn't actually cost me any water to run, just the fission fuel, and it generates pretty good power as a bonus. You could also recycle the sodium, but the coolant doesn't (as far as I can tell) affect waste production. 1mb of fuel becomes 1mb of waste, regardless of any other factors.

Nuclear Waste is a byproduct of running the Fission Reactor, it is Radioactive and if it is released it will contaminate the environment. A Small amount is stored in the Reactor itself but should be piped into other blocks for storage or use.

	So I just made the precosses to farm polonium pellet but Im left with the spent nuclear waste to deal, I was thinking of using ender tanks but it doesnt work, i made the reactor in a compact machine to avoid trouble and dont have room for the whole number of barrels to keep it in here.

Can someone tell me some advice?

Because it's in a compact machine just let the radiation leak and wear a hazmat suit when going into it Although I haven't played Stoneblock 3 maybe there's a better solution

2 of 5

You shpuld be able to use tunnels to transfer the waste to snother compact mschine (i dont know if in sb3 tunnels are avalisble in compact machines)

Soo much waist is there a better way to handle it than collecting it all with waist barrels ?

Top answer

If you wanna slim down and get rid of your waist, try eating less (yellow)cake.

2 of 18

Waste barrels, entangled (entangled blocks, not entangloporter) into a hypercube or compact machine, where a waste barrel is being placed and broken on a timer, assuring the cube is always irradiated and the barrel never gets full of spent waste. Then you either never go back, or you use the space to raise wasted radioactive bees for more good waste to make more antimatter. Either way your spent nuclear waste goes away.

October 29, 2025 - I’ve just tried so many ways I really want to be able to run my reactor all the time but I don’t want to have a big stack of waste barrels and even if I process it it still means keeping a big stack of spent nuclear waste barrels.
