Slovenia SMR option studies: US Project Phoenix pre-feasibility support and GEN energija SMR assessment
In February 2024 Slovenia was selected for US Project Phoenix support to complete a pre-feasibility study for potential future SMR deployment. In November 2024 GEN energija said it would intensify study of SMRs alongside the large JEK2 project. At a May 2026 event the Šoštanj thermal plant site was mentioned as a potential SMR location, no decision has been taken.
