Ukraine's state-owned nuclear power company Energoatom has launched the construction of two new units (units 5 and 6) at the Khmelnytskyi nuclear power plant in western Ukraine. The fifth unit, for which the first concrete cube has already been laid, will be the first power unit in the country that will use Westinghouse AP1000 technology (reactors of more than 1.1 GW each).
The Khmelnitsky nuclear power plant currently includes two 950 MW (1,000 MW gross) VVER V-320 reactors commissioned in 1988 and 2005 and two 1,035 MW (1,089 MW gross) VVER reactors are under construction. Construction on those units began in 1986 and 1987, was stopped in 1990 and resumed in 2020 (in 2016, Korea Hydro & Nuclear Power (KHNP) signed an agreement to resume the project).
In January 2024, the Ukrainian Ministry of Energy announced plans to start building four new nuclear reactors before the end of 2024 to make up for the lost capacity due to the Russian invasion and takeover of the 6 GW Zaporizhzhia nuclear plant in southern Ukraine. Two of the new units would be based on Russian-made equipment that Ukraine wants to import from Bulgaria, while the other two would use Westinghouse techonologies. All four new reactors would be built at the Khmelnytskyi nuclear power plant.
In 2022, nuclear represented 25% of Ukraine’s installed capacity with nearly 14 GW and 56% of its power generation.
