                    RERTR 2008
                  IAEA Mo-99 CRP
                        Background
•   99mTc reigns as the most used diagnostic tracer; 75-
    80% of all imaging  >25 million studies/year
•   Weekly 99Mo requirements: ~450000 GBq (12000Ci, ‘6-
    day curies’) at reference time (~50% for USA). Well over
    95% of 99Mo is produced using HEU targets (~50 kg)
•   Efforts to shift production of medical isotopes away
    from use of HEU (through RERTR, DOE/USA)
•   Some Member States (MS) of IAEA are seeking to
    become small scale, indigenous producers of 99Mo
•   Need to encourage and provide access to LEU
    technology or neutron activation (NA) methods as HEU
    is phased out from commercial use
                     RERTR 2008
                   IAEA Mo-99 CRP
                         Objectives
• Assist member states with adoption of LEU Cintichem
    (foil targets) or neutron activation (gel moly)
    technology.
•   Further demonstrate efficacy of LEU production of 99Mo
•   Advance intnl coopn for non-proliferation and nuclear
    security objectives, promote sustainable development.
•   Foster capacity building for local/regional self-
    sufficiency to meet 99Mo needs
•   Not Aimed: Engaging the large-scale industrial
    producers (but some are participating/contributing)

      Progress Status and Perspectives
• Several groups in the CRP will advance to
  demonstrating 99Mo production using LEU
• Objective findings on all related aspects: feasibility
  to adaptability – scope, requirements
• Possible role of a few groups significant: (i)
  MURR, USA to establish compliance of LEU moly
  for generator use; (ii) 4 groups already handling
  generator production, thus well placed to use local
  LEU moly
• 2 other groups will show the scale of applicability
  of gel moly system

                                Conclusion

• Many CRP participants continue to make excellent progress.
• Increasing technology transfer between the contract holders.
• Participants are developing physical and human resource infrastructure
    to carry out successful trial irradiation and processing.
•   Recent events have demonstrated the fragility of the global Mo-99
    supply infrastructure.
•   Medium term outlook for global Mo-99 supply highly uncertain due to
    aging isotope production reactors, lack of planned replacements.
•   Several participants have significant facilities that could be utilized in
    addressing global Mo-99 requirements.
•   Partnerships, joint ventures, or other commercial arrangements needed
    to further develop such potential alternative producers.
•   IAEA prepared to provide a forum to bring together all
    stakeholders for an objective analysis of requirements and to
    consider options for path forward.
