Waste inventories

Radioactive substances are characterised chemically and physically in the nuclear power plants and reprocessing facilities and at the Paul Scherrer Institute.

Nagra also maintains a centralised inventory of radioactive materials. Activities in this area are monitored by the federal safety authorities.

The extensive database that exists today provides information on the properties of all waste packages held in interim storage in Switzerland; this information can be accessed at any time. Waste certification procedures assess the suitability of the waste for later disposal in a geological repository.
