Slovakia - World Nuclear Performance Report

Slovakia has five operable VVER440/V-213 nuclear reactors: two at Bohunice V2, 140 km northeast of Bratislava; and three at Mochovce, 100 km east of Bratislava. Mochovce 3 was grid connected in January
2023, and unit 4 at that site is still under construction. 

In June 2023 Slovenské Elektrárne signed a memorandum of understanding with Framatome on the development of European nuclear fuel for VVER-440 reactors. In August 2023 the utility signed a long-term agreement with Westinghouse for the licensing and supply of VVER-440 fuel assemblies.

In May 2024 the government approved a plan for a new 1.2 GWe unit near the existing Bohunice plant. Detailed plans are being developed, and France, South Korea and the USA are among the potential project partners.

Slovakia signed a memorandum of understanding in June 2023 with a range of partners – US Steel Košice, the Slovak Electricity Transmission System, VUJE, the Office of Nuclear Supervision and the Slovak Technical University in Bratislava – to support development of SMRs. 

Slovakia is one of the first recipients of support through the US-funded Project Phoenix, announced at the COP27 conference on climate change held in Sharm el-Sheikh, Egypt in 2022. The initiative aims to support energy security and climate goals by creating pathways for coal-to-SMR plant conversions. In February 2024 Slovenské Elektrárne said that staff from Project Phoenix implementation partner Sargent & Lundy had visited its Bohunice and Mochovce nuclear power plants and the Nováky and Vojany coal-fired plants to carry out field surveys.
