Despite the full-scale war, Ukraine continues to be a part of the global supply chain for the nuclear power industry. Ukrainian engineering companies continue to design, manufacture, and supply high-tech equipment, fulfill international contracts, and participate in the modernization of nuclear power plants.
Ukraine as a Vital Link in the Global Supply Chain
Ukraine is one of the few countries in the world with a complete nuclear power operating cycle. Before the war began in 2022, the country operated 15 power units at four nuclear power plants , and nuclear generation accounted f or more than half of its electricity production .
Decades of industry development have created a strong nuclear instrumentation engineering tradition in Ukraine. Domestic companies specialize in:
- Digital instrumentation and control (I&C) systems;
- Reactor safety systems;
- Electrical equipment;
- Relay protection and automation systems;
- Components for power unit modernization;
- Engineering support, testing, and service support.
Ukrainian solutions are used not only at domestic NPPs but also in international modernization projects that require compliance with the regulatory requirements in various countries, including those in Europe and North America.
Wartime Challenges for the Industry’s Engineering Companies
After 2022, Ukrainian manufacturers found themselves operating under unprecedented conditions. Companies had to simultaneously address personnel safety, maintain production continuity, and restructure international logistics.
The main challenges included:
- Constant threat of missile and drone strikes;
- Power supply disruptions;
- Need to develop contingency production scenarios;
- Changes to transport routes due to the disruption of traditional logistics;
- Retaining qualified engineering teams amid an outflow of specialists;
- Fulfilling international contracts within the agreed timeframes.
The situation was even more difficult for companies in the nuclear industry. Production of equipment for NPPs cannot be relocated or simplified quickly: every product is subject to rigorous quality control, documentation, testing, and production-process traceability in accordance with international requirements.
Resilience and Fulfillment of Commitments
Despite exceptionally difficult conditions, Ukrainian nuclear machinery and instrumentation manufacturers have managed to preserve their teams, expertise, and production capacity.
For example, during the war, Radiy continued operating its design groups, production units, and test facilities, ensuring the continuity of engineering processes and the delivery of international projects. Significant efforts were directed toward maintaining quality management systems, retaining specialist expertise, and developing proprietary technologies.
It is particularly important that Ukrainian manufacturers not only adapted to the new conditions but also continued to invest in development and fulfill their contractual obligations. Work on new products, equipment modernization, digital solutions, and production process improvements continued without interruption. This enabled them to remain competitive and meet the expectations of international customers even during the period of greatest uncertainty.
Engineering Resilience as a Contribution to Global Energy Security
In a world where energy security and nuclear safety are becoming increasingly important, Ukrainian engineering companies remain reliable participants in the global technology supply chain for the nuclear power industry. More information about the portfolio of Ukrainian engineers is available on the company’s website . Their professionalism, responsibility, and resilience contribute not only to Ukraine’s recovery but also to a safe and stable future for the global nuclear power industry.
