Radics Strengthens Global Collaboration at World Nuclear Exhibition 2025
10.11.2025
16–20 February 2026 - Radics team had the opportunity to participate in the International Atomic Energy Agency (IAEA) Consultancy Meeting on the use of digital technologies in nuclear power plants, with a specific focus on Verification and Validation (V&V) of software for nuclear I&C systems.
The meeting provided a valuable platform to share industry experience and engage in in-depth discussions on some of the most critical aspects of digitalization in nuclear power plants. Experts from China, France, Germany, Hungary, the Netherlands, Pakistan, Sweden, Switzerland, Ukraine, the United Kingdom, and the United States took part in the discussions.
With her presentation addressing common challenges and clarifying V&V expectations across the full project lifecycle, Radics Deputy Chief Operating Officer Nataliia Rvachova supported the refinement of IAEA Technical Report Series No. 384– Verification and Validation of Software Related to Nuclear Power Plant Instrumentation and Control. This document serves as an important source of guidance document on digital I&C software V&V processes for nuclear power plants.
Originally issued in 1999, Technical Reports Series No. 384 is currently undergoing a comprehensive revision to reflect modern digital technologies and current regulatory practices. The objective of the updated document, planned for release in 2026–2028, is to provide clear recommendations to IAEA Member States, regulatory authorities, vendors, and nuclear operators on performing effective verification and validation of software during the development and modernization of I&C systems.
During the meeting, participants reviewed the structure and content of the existing document and discussed approaches for its full update. Particular attention was given to key challenges faced by both suppliers and users of I&C systems, including:
- Determining the appropriate scope and depth of V&V activities;
- Ensuring software testing as part of the complete I&C system, not only as standalone software;
- Selection adequate testing methods and techniques;
- Addressing different categories of software, including legacy software, newly developed software, and FPGA-based platform software.
The consultancy meeting marked the first step in a structured update process. Working groups have been established to prepare draft sections of the revised document, with further coordination meetings planned in the coming months and a major technical meeting scheduled for October. A final draft is expected to be submitted to the IAEA for review prior to publication.
Participation in this consultancy meeting reinforced Radics’ commitment to nuclear safety and to the continuous advancement of international best practices in the nuclear industry.
