Radioactive waste

Society produces a variety of waste that must be disposed of in a way that ensures the protection of humans and the environment without imposing undue burdens on future generations. Radioactive waste is no different.

Radioaktive Abfälle
Main flows of waste in the Swiss waste management concept

Low-level, intermediate level and high-level


Two types of repositories are foreseen for radioactive waste: one for the disposal of low intermediate level waste (L/ILW) and one for the disposal of high-level waste (HLW). HLW consists of spent fuel from nuclear power plants and high-level vitrified residues from the reprocessing of spent fuel. They generate heat due to radioactive decay. L/ILW consists of radioactive waste from the operation and the decommissioning of nuclear power plants, but also from medicine, industry and research. Radioactive waste is conditioned in such a way that it can be safely stored and disposed of. Until its final disposal in deep geological repositories, radioactive waste is stored in interim storage facilities.
