Move the left green slider to the right to make this building transfer the stored fuel into the ship. This building will also request trucks to keep its storage filled up to the green marker.
Product into which the current stored waste transforms after it is no longer radioactive. Only some waste can be retired this way (more information can be found in the recipe book).
This does not relate to efficiency of this sorting plant. Instead it defines how efficiently your island converts waste into recyclables in places like maintenance depots and settlement. So for instance 40% efficiency means that 40% of the iron used in maintenance ends up in recyclables. What is not converted into recyclables gets wasted. Note that postponing processing of recyclables due to expectations of future increase in efficiency won't help as the conversion is done when recyclables are created not when they are sorted. Efficiency can be increased via research and edicts.
A special underground storage facility that can safely manage any radioactive waste without causing any danger to the island’s population. Leaving a legacy for the next generations to come.
A complex facility which reprocesses radioactive material by isolating fission products (material that is no longer fissile and would slow down reaction if left in a reactor). Isolated waste decays faster, allowing it to be disposed of in a reasonable time span. The isolated waste is vitrified using molten glass into a solid form for easier storage.
