US Laboratory Advances Californium-252 Production Process
A new method from Oak Ridge National Laboratory reduces californium-252 production time, crucial for nuclear energy and security. As demand rises with US nuclear expansion plans, efficient isotope production becomes vital for various applications.

Oak Ridge National Laboratory (ORNL) has developed a new chemical process that could reduce the production schedule of californium-252 by a week or more. Currently, ORNL is the sole producer of this rare radioactive isotope in the Western world, which is critical for starting nuclear reactors and various industrial applications.
The anticipated increase in demand is driven by US federal policies aimed at expanding nuclear energy, including plans for 10 new reactors by 2030. The laboratory aims to enhance production efficiency by introducing a novel solvent extraction technique that streamlines the processing of californium-252, which has historically been a lengthy process.
This efficiency upgrade could support the growing needs for californium-252, including applications in national security and industrial sectors. The implications for future nuclear energy initiatives are significant, as improving the supply chain for this isotope will be essential for both domestic and international needs.
