Management and Disposal of Spent Nuclear Fuel


  • Prior to the 2003-2020 moratorium on reprocessing, some operators made contracts with French and British companies to reprocess approximately 1,200 metric tons fuel to be returned and reused in domestic plants
  • SNF is currently stored first wet onsite before transferred to wet or dry storage at independent interim facilities (two dry, one wet)
  • The process for DGR site selection by the National Cooperative for the Disposal of Radioactive Waste (NAGRA) is ongoing and a Parliamentary approval of the license is expected in approximately 2030
  • Public consultation and referenda are to be solicited throughout the process
  • NAGRA and the Paul Scherrer Institute also work on radionuclide research for waste management and Switzerland has international initiatives to research DGR siting


  • Switzerland’s safeguards agreement (INFCIRC/264) entered into force in 1978 and the additional protocol in 2005
  • Switzerland signed the Joint Convention in 1997 and ratified in 2000
  • NPP operators are responsible for fuel cycle management under the 2003 Nuclear Energy Act and 2004 Nuclear Energy Ordinance and operate with a “polluter-pays” policy
  • Future reprocessing is prohibited under the Energy Strategy 2050 and so spent fuel policy includes final disposal
  • Swiss spent fuel cannot be disposed of in another country’s DGR
