Abstract

Non-uranium production of ⁹⁹Mo via neutron capture or by photonuclear reaction using an electron accelerator is receiving considerable attention. For commercial production of ⁹⁹Mo, post-irradiation processes must incorporate a robust design for easy scale-up. Once developed, large-scale chemical processes must be optimized for hot-cell operations and potential automation. Here we present experimental results on the large-scale dissolution of sintered Mo disks using three 50% hydrogen peroxides from different suppliers. Dissolution rates obtained for 600-g Mo batches and potential reasons for different dissolution behaviors is discussed.
