Building a Global Partnership to Supply Medical Isotopes
without the use of Highly Enriched Uranium

The U.S. Department of Energy’s (DOE) National Nuclear Security Administration (NNSA) is pleased to announce that it will host a Molybdenum-99 (Mo-99) International Symposium in Prague, Czechia at the InterContinental Prague Hotel from April 26-30, 2020. The symposium will highlight global progress being made towards eliminating highly enriched uranium (HEU) from medical isotope production, showcase global non-HEU Mo-99 production technologies and provide a technical and policy forum for discussion of Mo-99 industry and supply issues. 

The five-day event is being organized by the Department of Energy’s Argonne National Laboratory in cooperation with the International Atomic Energy Agency, and will include oral presentations of technical and policy papers, a poster session and a technical tour of Research Reactor LVR-15, which provides irradiation services for Mo-99 producers. More information regarding DOE/NNSA’s Mo-99 program can be found here.

NNSA invites interested stakeholders to register for this event and to submit an abstract for oral or poster presentation at the symposium in one of the following Mo-99-related topical areas:

  • International HEU Minimization and Conversion
  • Establishing Mo-99 Supplies in North America and Abroad
  • Regulatory Challenges and Lessons Learned
  • Full Cost Recovery Challenges and Lessons Learned
  • The End-User Perspective (Healthcare Organizations and Radiopharmacies)
  • The Clinical Perspective of Mo-99 and Tc-99m-based Radiopharmaceuticals
  • The Mo-99 Target Residue Waste Challenge
  • Bringing Mo-99 to Market: Lessons Learned
  • Security of Supply
  • Fission and Neutron Capture Production Technology Advances
  • Accelerator Production Technology Advances
  • Emerging Production Technologies and Capabilities

Please utilize the links provided along the left margin of this web page to learn more about the venue, schedule for submitting an abstract for oral or poster session information, technical tour and how to participate in the 2020 Mo-99 International Symposium.
