Reactor-based Production of Mo-99

Session Organizers:
Natesan Ramamoorthy, Homi Bhabha National Institute, India
James S. Welsh, NIU Institute for Neutron Therapy, USA

The parent nuclide of Tc-99m, Mo-99, is mainly extracted for medical purposes from the fission products created in neutron-irradiated U-235 targets, the majority of which is produced in five nuclear research reactors around the world using highly enriched uranium (HEU) targets. Smaller amounts of Mo-99 are produced from low-enriched uranium in at least three reactors. Production of Mo-99 by neutron activation of natural molybdenum, or molybdenum enriched in Mo-98, is another, currently smaller, route of production. The session will review current efforts in advancing the production of Mo-99 using the non-HEU options. Alternate / planned new reactor production facilities are encouraged to contribute to the session.
