ANSTO is the home of Molybdenum-99 (Mo-99) production within Australia. The end-to-end process is situated onsite at the Lucas Heights campus. Utilising the OPAL reactor, ANSTO supplies to both the domestic and international markets the life-saving Mo-99 nuclear medicine product. Processing of Mo-99 occurs within the bulk Mo-99 manufacturing facility (also known as ANM) while dispensing of the final product to Technetium generators occurs at our nuclear medicine Processing and Distribution Facility (also known as Building 23).

The treatment and storage of the intermediate level liquid waste (ILLW) product from the manufacturing of Mo-99 is an ongoing problem for many organisations around the world. Final wasteform storage is a significant challenge due to durability, waste volume and environmental concerns. ANSTO has developed a world first Synroc Technology, which is able to fixate the liquid waste into a solid wasteform (Synthetic rock – Synroc). This makes the waste easier to handle and ready for final stage repository. The SYMO facility currently under construction is a first of a kind plant specifically designed to treat the alkaline waste from current Mo99 production, using Synroc technology.
