Ukraine plans to expand its cooperation with the American company Westinghouse. To this end, a delegation of Ukrainian nuclear specialists visited the company’s production facilities in Sweden, where fuel for Ukraine’s nuclear power plant reactors is manufactured, UNIAN reports.
The purpose of the visit was to inspect the implementation of the contract for supplying fuel to the reactor units of the Rivne Nuclear Power Plant (RNPP), as well as to deepen cooperation aimed at transitioning Ukraine’s energy sector from Russian nuclear fuel to Western technologies.
The delegation included specialists from the Rivne NPP, led by CEO Taras Tkach. In Sweden, they reviewed the full cycle of Westinghouse fuel production—from the creation of the fuel matrix to final packaging and preparation of fuel assemblies for shipment.
“Rivne NPP has a specific feature—the presence of low-capacity VVER-440 reactors. For decades, there was no alternative to Russian nuclear fuel for them, so Units 1 and 2 operated exclusively on it until 2023,” the report said.
Journalists note that Ukraine began pursuing energy independence even before Russia’s full-scale invasion. As part of its nuclear fuel diversification program, a contract was signed with Westinghouse Electric Company in September 2020 to supply fuel assemblies for VVER-440 reactors. In September 2023, the first batch of fuel was loaded into the reactor of Unit 2 at Rivne NPP. The work was completed in a record time of one and a half years.
As of 2026, Westinghouse nuclear fuel is partially or fully used at all units of the Rivne NPP.
According to CEO Taras Tkach, the next stage of cooperation will involve implementing an 18-month fuel cycle and increasing the capacity of power units. Amid electricity shortages, this step is strategically important for the stability of Ukraine’s energy system and meeting economic needs.
“Currently, our joint efforts are focused on developing new fuel assemblies designed for an 18-month fuel cycle, as well as ensuring the operation of our VVER-1000 units at higher power levels. An important step in achieving these goals will be studying the experience of European partners already transitioning to extended fuel cycles. Unlike European NPPs that are switching to a new cycle using Russian-made fuel, Rivne NPP intends to successfully complete this transition using Westinghouse fuel,” the CEO stated.
