Energoatom is moving into local production of components used in Westinghouse nuclear fuel assemblies, a step that strengthens Ukraine’s long-term energy security and reduces dependence on legacy supply chains. The company said its Atomenergomash division has received the materials needed to manufacture the first batch of tailpieces for VVER-1000 fuel assemblies.
The first production batch is expected to take four months. After manufacturing, the tailpieces will be used in the production of nuclear fuel for Ukrainian nuclear power plants. The process is part of Energoatom’s agreements with Westinghouse Electric Sweden AB on localization of components for fuel assemblies.
Localization moves from agreement to production
The tailpiece is one of the structural elements of a fuel assembly, so localization is not only a symbolic step. It requires qualified materials, controlled machining, strict inspection and predictable industrial discipline. For Ukraine, the ability to make such components domestically adds resilience to a sector where reliability and certification are critical.
Energoatom also said qualification is continuing for another component, the heads of fuel assemblies. That means the localization program is being built gradually, component by component, rather than as a single administrative declaration.
In 2025, Energoatom and Westinghouse Electric Company signed agreements on nuclear fuel production in Ukraine. The strategic meaning is clear: Ukrainian nuclear generation needs stable access to fuel and components, while the country works to remove dependence on Russian supplies.
If the program expands successfully, Ukraine will gain more control over its nuclear fuel chain. That matters not only for power generation, but also for industrial confidence, energy planning and the broader shift toward supply chains aligned with Ukraine’s partners.
