Ukraine begins its own production of nuclear fuel components for VVER-1000 reactors

Ukraine is taking a decisive step towards complete energy independence by starting local production of key components for nuclear reactors.

In May 2026, the National Nuclear Power Generating Company Energoatom announced the start of serial production of liners for VVER-1000 fuel assemblies at Atomenergomash facilities. This stage was a logical continuation of many years of cooperation with the American-Swedish company Westinghouse Electric Sweden AB and opens up new horizons for the Ukrainian nuclear industry.

From the first deliveries to our own production

Ukraine began using Westinghouse fuel in 2015. At that time, supplies were made exclusively from abroad. Since 2022, Energoatom has intensified negotiations on localization. In 2023, Energy Minister Herman Galushchenko confirmed plans to create a full-fledged production line. Now, in 2026, these plans are becoming a reality: the first batch of liners is already in production and will be ready in four months.

Technical details of the new stage

Atomenergomash has received all the necessary materials and qualifications from Westinghouse. The company's quality system fully meets the requirements of the American partner. In parallel, the qualification of heads for fuel assemblies is underway. After the successful completion of this process, Ukraine will be able to manufacture almost a complete set of fuel assembly components on its own territory.

Construction of a plant in Southern Ukraine

The Cabinet of Ministers of Ukraine has approved the construction of a specialized plant next to the South Ukrainian NPP. The site was not chosen by chance: there is already a developed infrastructure, qualified personnel and direct access to the reactors. According to plans, the first stage of the plant will be operational in 2027, and full capacity will allow providing fuel to all Ukrainian NPPs.

International context and security

The localization of nuclear fuel production meets IAEA standards and European requirements. Westinghouse Electric Sweden AB has officially recognized Atomenergomash as a qualified supplier. This means that Ukrainian components can be used not only in Ukraine, but also in other countries where VVER reactors are operated.

Economic effect for the state

The transition to domestic production will reduce foreign exchange costs for fuel imports. According to experts, the savings can reach tens of millions of dollars each year. In addition, new jobs are created in the Mykolaiv region and neighboring regions. The development of high-tech production stimulates related industries - mechanical engineering, metallurgy and logistics.

Energy security in 2026

As of May 2026, Ukraine continues its course towards diversifying its energy sources. Its own nuclear fuel is becoming one of the key elements of this strategy. It reduces dependence on external suppliers and increases the resilience of the energy system in the face of global challenges.

Prospects for the coming years

After launching the plant in Yuzhnoukrainska, Energoatom plans to expand its product range. The possibility of producing fuel for VVER-440 reactors and promising small modular reactors is being considered. International partners have already expressed interest in cooperation.

Visnovok

The start of production of nuclear fuel components in Ukraine is not just a technical achievement. It is a symbol of a new era, when the country takes responsibility for its own energy destiny. Each manufactured liner brings Ukraine closer to full independence in the nuclear sphere.
