Issue description:

Any time I try to pump waste from my Fission reactor using ultimate pressurized tubes into a tank or into a PRC, it disappears

Steps to reproduce:

1. Set up a normal Fission setup (water cooled, 5x7x5 reactor, 5x9x5 turbine)
2. Wait until waste builds up in the reactor
3. Try to pump it out into a tank or PRC

Version (make sure you are on the latest version before reporting):

Forge: 36.1.0
Mekanism: 10.0.21
Other relevant version: Minecraft 1.16.5

Right click the tubes with a network reader are you sure it isn't just in them?

Okay so, I worked out that it has to go into a Solar activator. But same issue applies pumping Polonium out. Network reader says its coming out and staying in buffer, but the tank won't fill otherwise.

You can't store radioactive materials in chemical tanks only in waste barrels (polonium/plutonium won't decay in them)

Oh, I understand. So they act as the chemical tank for radioactive materials and can then pump into PRCs?

You should probably just process polonium or plutonium as needed and then put the spent waste into the barrels, but you can also store radioactive materials in barrels and extract from them if needed. You should join the discord server since you'll likely have more questions.

Thanks. Joined in, will direct further questions there.
