Management and Disposal of Spent Nuclear Fuel


  • NPP SNF is stored wet onsite for up to 12 years and then is transferred to interim dry storage onsite
  • SNF from the only critical research reactor is stored wet at the Higher Active Waste (HAW) facility in Řež
  • In 2007, 2 metric tons SNF were returned to the Russian Federation for reprocessing and storage; 112 HEU fuel assemblies were also reprocessed in Russia in 2013
  • The Czech Republic participates in the IAEA International Project on Innovative Nuclear Reactors and Fuel Cycles


  • The Czech Republic is party to the Euratom IAEA safeguards agreement since 2009 (INFCIRC/193), as well as its additional protocol (2009)
  • The Czech Republic signed the Joint Convention in 1997 and submitted its approval in 1999
  • According to the Atomic Act, SNF management and interim storage is the owner’s responsibility; the decision to reprocess is still up to owners but no national policy has been published
  • The Radioactive Waste Repository Authority (SÚRAO) is responsible for safe final radioactive waste and spent fuel disposal
  • In accordance with the EU’s recommendations, the Czech Republic intends to begin preliminary examination of how to proceed towards DGR disposal; the preliminary plan is for site selection by 2025, construction starting 2050, and operation beginning 2065
