Background
•

•
•
•
99mTc
reigns as the most used diagnostic tracer; 7580% of all imaging  >25 million studies/year
Weekly 99Mo requirements: ~450000 GBq (12000Ci, ‘6day 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 selfsufficiency to meet 99Mo needs
Not Aimed: Engaging the large-scale industrial
producers (but some are participating/contributing)

Fostering Provision of Materials, Information Exchange
• Aluminium tubing shipped from ANL (03/06)
• KAERI supply of test foils with IAEA facilitation for transfers.
•
•
•
•
•
LEU foils delivered to 4-5 participants (2007)
Glassware procured by IAEA with DOE funding; received
by late 2006/early 2007
ANSTO safety documentation distributed (early 2007)
MURR assistance in performing and evaluating thermal
hydraulics calculations
BRIT/BARC assistance with gel generator know-how
CRP website increasingly important tool with several
technical reports posted

Training/Technical Assistance and Procurements
• BRIT (India), February 2008, 1 Kazakhstan SV re: portable
•
•
•
•
•
gel moly generator technology
BATAN, March 2008 - 1 Chilean, 2 Libyan Fellows LEU
ingot rolling process, foil target fabrication, waste treatment
CNEA, June 2008 - 1 Libyan SV, QC for Mo-99 production
CCHEN, August 2008 - 1 Poland SV, LEU annular target
fabrication equipment design, assembly, welding (2 Libyans
unable to reach Chile)
Additional aluminum tubes procured by ANL for Chile and
Poland
Bids for Cintichem laboratory equipment and supplies for
Libya; evaluation underway
RERTR 2008: IAEA Mo-99 CRP
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.
