Soil or Waste Stacks.

Every soil or waste stack will terminate in a stack vent that leads to outside air or a vent header.
High-level radioactive wastes are the highly radioactive materials produced as a byproduct of the reactions that occur inside nuclear reactors. High-level wastes take one of two forms:1  Spent (used) reactor fuel when it is accepted for disposal.2  Waste materials remaining after spent fuel is reprocessed.owever they must be included in any high-level radioactive waste disposal plans, along with all high-level waste from spent reactor fuel. Because of their highly radioactive fission products, high-level waste and spent fuel must be handled and stored with care.
