Sources: 4. Developments: 2. The development of a deep geological radioactive waste repository in the Czech Republic has faced procedural and legal setbacks. In late September 2026, the Radioactive Waste Repository Administration (SÚRAO) canceled a tender for geological drilling at four potential sites, citing changes to the building law. The Platform Against Deep Repositories expressed concern that this cancellation, following similar cancellations in late 2025, could jeopardize the 2028 and 2030 deadlines for site selection. By mid-October 2026, the dispute shifted toward environmental regulatory compliance. Several municipalities filed a formal complaint with the European Commission, alleging that the Czech Ministry of the Environment unlawfully bypassed the mandatory Strategic Environmental Assessment (SEA) process. The complainants argue that because the planned capacity for waste is increasing significantly due to new nuclear projects at Dukovany and Temelín, a new SEA is legally required to evaluate the updated management concept. ## Timeline ### 2026-10-15: Czech municipalities file EU complaint over nuclear waste site assessments Czech municipalities near potential nuclear waste repository sites have petitioned the European Commission, alleging the Ministry of the Environment bypassed mandatory strategic environmental assessments. 2 sources. https://clstr.news/cluster/czech-municipalities-file-eu-complaint-over-nuclear-waste-site-assessments ### 2026-09-26: SÚRAO cancels geological drilling tender for nuclear waste sites SÚRAO has canceled a tender for deep geological drilling at four potential radioactive waste repository sites in the Czech Republic due to changes in the building law, potentially delaying site selection. 2 sources. https://clstr.news/cluster/srao-cancels-geological-drilling-tender-for-nuclear-waste-sites --- Cite as: Czech nuclear waste repository site disputes.
