Program and Workshop Overview

The U.S. Department of Energy’s National Nuclear Security Administration through its Global Threat Reduction Initiative (GTRI) implements the long-standing U.S. policy to minimize and eliminate the use of highly enriched uranium (HEU) in civilian applications by working to convert research reactors and isotope production facilities to the use of low enriched uranium (LEU). Over the past few years, unexpected shutdowns at the major molybdenum-99 (Mo-99) production facilities have resulted in significant shortages of this important medical isotope. Because of this, the United States is currently situated at the nexus of two related priorities: discouraging the use of proliferation-sensitive HEU in civilian applications and overcoming a health crisis from the lack of a sufficient, reliable supply of Mo-99.

GTRI provides support to establish reliable supplies of Mo-99, produced without HEU, for the United States by providing assistance to convert current production from HEU targets to LEU targets and to accelerate existing commercial projects in the United States to produce Mo-99 without the use of HEU by the end of 2014. Through these actions GTRI's Mo-99 program is addressing both issues of nonproliferation and reliability of supply.

NNSA’s 2013 Mo-99 Topical Meeting, hosted by Argonne National Laboratory, will take place in Chicago, IL from April 1-4, 2013 with an optional tour of Argonne National Laboratory on April 5. This meeting is intended to serve as a workshop where international and domestic policy and technical experts can gather to present and discuss progress toward achieving the production of Mo-99 without the use of HEU in support of nonproliferation objectives and global reliability of supply.


NNSA is inviting attendees to submit an abstract for oral presentation at the Topical Meeting in one of the following sessions:

  • Technical, Regulatory & Economic Challenges of Producing Mo-99 without the Use of HEU
  • Future U.S. Domestic non-HEU Mo-99 Production
  • Current and Future Global non-HEU Mo-99 Production
  • Current State of Technology Development in Support of Mo-99 Production
