SNETP is a highly significant association for CVŘ as it defines the priorities for research and development in the field of nuclear energy. CVŘ places importance on its participation in the NUGENIA association, which is part of SNETP and focuses on supporting the safety, reliability, and efficiency of nuclear power plant operations. Additionally, CVŘ is actively involved in the NC21 initiative (The European Nuclear Cogeneration Industrial Initiative). Within this initiative, the GEMINI 4.0 project was prepared and initiated in 2022. This project is focused on the development of a nuclear cogeneration demonstrator funded through the Horizon Europe Euratom program.
