I wanted to share my testing for waste management from Reika's ReactorCraft in version v6f.
Fission reactors always produce waste of two varieties, short (<1 year) and long term. These are stored differently.
All waste should be piped from the reactor cores where a buildup would reduce the efficiency, and inserted into a spent fuel container. This container should be surrounded by water, or if in a finite water world it should have water constantly applied via RoC liquid spiller or BC floodgate to the north face of the unit. Short term waste will decay inside this container which creates heat that can't be harvested or cooled with fins. During the decay the water blocks adjacent to the unit are used up for cooling, and waste neutrons will escape in all six directions from the block. To stop these from hurting the environment, you need to shield the waste container with three deep HSLA steel blocks on each of the six axes at a distance to allow for water. Other than the neutrons and heat, these containers don't spread radiation effects.
Long term waste can be piped out of the spent fuel container bottom, using it as a filter for long vs short term waste. The long term waste should be piped into waste disposal drums where it will essentially never disappear. These drums should be buried. Radiation effects are caused by these drums and the range increases as more waste is added, to a maximum of about 13 blocks radius. If they are not visible they are safe, so surround them with solid blocks to prevent the radiation effects, and make sure to fill in any diagonals to fully encase them.
Last of all to prevent sickness while handling the waste or managing the drums, you'll need a hazmat suit. These make you proof against the drums and neutrons.
Good luck!
