The French government has announced the launch of a new research program focused on fission nuclear energy, as part of its broader energy transition strategy. Funded through the public investment plan known as France 2030, this initiative is managed by the French National Center for Scientific Research (CNRS) in partnership with the Commissariat à l'énergie atomique et aux énergies alternatives (CEA). The program is allocated 18 million euros over six years, aiming to revitalize nuclear research that has seen a slowdown in recent years. The initiative seeks to generate new fundamental knowledge in nuclear science, reinforce experimental infrastructure, and train a new generation of researchers specializing in nuclear energy. This includes work on both the theoretical and practical aspects of nuclear processes, which are essential for advancing the field and improving the safety and efficiency of nuclear power. Half of the funding will be used to support research staff through doctoral and postdoctoral contracts, ensuring a steady supply of skilled scientists in the field. The remaining funds will be directed toward acquiring and maintaining scientific equipment and infrastructure, such as particle accelerators, experimental reactors, and radiochemistry laboratories. These facilities are crucial for conducting advanced research and testing new materials and processes. Among the research goals is the study of corium, a molten mixture of materials that forms when a nuclear reactor core melts during an accident. Understanding corium's behavior is vital for improving nuclear safety and accident management. Researchers will also investigate the long-term fate of radioactive nuclei, which is essential for managing nuclear waste and ensuring environmental safety. Additionally, the program aims to develop new materials that can withstand prolonged exposure to the intense radiation found in nuclear reactors, which could lead to more durable and efficient reactor designs.
