Slovakia's five existing VVER-440/V-213 units at the Bohunice and Mochovce sites are owned by Slovenské elektrárne. A sixth VVER-440 at Mochovce (unit 4) was expected to start operation in 2025.

New capacity

Large-scale reactors

The Slovakian government approved plans for a new 1250 MWe unit, near the Bohunice nuclear power plant, in May 2024.148 In August 2025 prime minister Robert Fico said the European Commission has positively assessed the content of the draft agreement between the governments of Slovakia and the USA on cooperation in the field of nuclear energy, and that the US government had approved the proposal. Fico said that the agreement was a basic prerequisite for the conclusion of another intergovernmental agreement on the construction of a new 1250 MWe Westinghouse unit in Bohunice.149

Small-scale reactors

A feasibility study, as part of the US-funded Project Phoenix, is looking into the potential for small modular reactors in Slovakia with an indicative timeline to 2035. The aim is to complete the feasibility study in 2025, with the initial SMR design and licensing process running from 2026 to 2029, procurement of major components from 2030 to 2033 and "implementation project, construction, commissioning" in 2035.150

In January 2025 France-based Newcleo signed framework agreements with Slovakian companies JAVYS and VUJE which could lead to up to four of its 200 MWe lead-cooled fast reactors at the Bohunice site.151

In August 2025 Slovenské elektrárne and Synthos Green Energy signed a memorandum of understanding to explore the possible deployment of GE Vernova Hitachi's BWRX-300 small modular reactors.152
