  1. Status of IAEA Mo-99 Activities Ira N. Goldman, Natesan Ramamoorthy, and Pablo Adelfang International Atomic Energy Agency 11 June 2007 NAS Medical Radioisotope Study Washington, DC

  2. IAEA Mo-99 Activities Background • Support HEU minimization • Consultants Report on Small-Scale Fission Molybdenum Production from Low Enriched Uranium, IAEA, July 2003 • Consultants Meeting on Mo-99 from LEU, IAEA, November 2004 • Coordinated Research Project on Developing Techniques for Small-Scale Indigenous Production of Mo-99 Using LEU or Neutron Activation (T.1.20.18) – ongoing 2005-2009

  3. IAEA Mo-99 Activities CRP Objectives • Foster capacity building for local/regional self-sufficiency and access to nuclear medicine, sustainable development. • Assist member states with adoption of LEU-Modified Cintichem (foil targets) or neutron activation (gel moly) technology. • Provide technical and material assistance to perform trial irradiations, bench-scale separation of Mo-99, meeting purity specifications, and prepare TECDOC. • NOT aimed at existing large-scale producers (but they are participating/contributing)

  4. IAEA Mo-99 Activities CRP Participants Contracts: • LEU Foil: Chile (CCHEN), Libya (DRETC), Pakistan (PINSTECH), Romania (INR Pitesti) • Neutron Activation/Gel Moly – Kazakhstan (INP), Romania (IFIN-HH Magurele) Agreements: • Argentina (CNEA), India (BARC-BRIT), Indonesia (BATAN), Korea (KAERI), US (ANL), US (MURR) • NEW - Poland (POLATOM) • RECEIVED – Egypt (EAEA) • EXPECTED – Russia (Institute of Nuclear Materials Zarechny)

  5. IAEA Mo-99 Activities 2nd RCM Bucharest April 2007 • Extensive discussions on technical topics including: • Foil target thermohydraulics analysis using computational fluid dynamics code Fluent (University of Missouri College of Engineering/MURR) • Analysis of irradiation of LEU foil in Tajoura reactor (Libya) • Thermal Contact Resistance of LEU foil targets (AREVA-CERCA) • Specification of LEU foils fabricated using the cooling-roll casting method developed by KAERI. • Basic principles of Current Good Manufacturing Practices (MURR). • Operational experience in gel moly production, for individual generators (India) and centralised facility (Kazakhstan) • Issues related to gel moly process gadgets. • Calcining uranyl nitrate solutions (ANL) • Visit to Pitesti TRIGA reactor and hot cells; New coordinated work plans and action items adopted, country work plans reviewed/revised. • Requests for additional technical assistance from IAEA.

  6. IAEA Mo-99 Activities Recent and Future Activities • Report on First Generation 1-D Thermal Contact Resistance Model of LEU-Foil in Cylindrical Geometry (MURR) • Report on calculations of LEU foils using ORIGEN S from SCALE 4.4a (Chile) Future Fission Moly • KAERI LEU foil supply/transport arrangements nearly concluded, shipments to occur in coming month(s). • Finalization and submittal of safety cases to regulatory authorities (Fall 2007). • Final preparation of hot cells and waste process (Nov 2007). • LEU-foil target irradiation (December 2007). • Processing of irradiated targets (February 2008). Gel Moly • Improved gel moly filling (wet systems) in generators. • Documenting engineering features of the process gadgets/facility.

  7. IAEA Mo-99 Activities Homogenous Solution Reactors • Consultancy Meeting on Assessment of Homogenous Aqueous Solution Reactors for the Production of Mo-99 and other short-lived radioisotopes, Vienna, 20-22 June 2007. • Info exchange, produce status report on “state of the art” of the technology. • Expected participants: Argentina, China (4 NPIC, 3 “cost-free”), France, Netherlands (Tyco), Russia (3 including Kurchatov and IPPE), U.S. (3 including ANL, BWXT)

  8. IAEA Mo-99 Activities Support • U.S. Department of Energy (GTRI) – direct funding for Mo-99 CRP including procurements, in-kind thru ANL. • Nuclear Threat Initiative (NTI) – project management support. • ANSTO, AREVA-CERCA, BWXT, MDS Nordion, NECSA, NRG Petten, Tyco Health Care - in-kind

  9. IAEA Mo-99 Activities Further Info/Points of Contact • www.iaea.org/OurWork/ST/NE/NEFW/nfcms_researchreactors_Mo99.html • Natesan Ramamoorthy, Director, Division of Physical and Chemical Sciences, Department of Nuclear Sciences and Applications (n.ramamoorthy@iaea.org) • Pablo Adelfang, Cross-Cutting Coordinator for Research Reactors, Department of Nuclear Energy (p.adelfang@iaea.org) • Ira Goldman, Department of Nuclear Energy (i.goldman@iaea.org) • Edward Bradley, Department of Nuclear Energy (e.bradley@iaea.org)
