“Importantly, these new production methods for Mo-99 do not require highly enriched uranium,” said Nina Rosenberg, program director of nuclear nonproliferation and security at Los Alamos. “Dr. May has used the scientific resources of the Laboratory to have a positive impact on medical treatment as well as nuclear nonproliferation.”
Efforts to develop an alternative production capability of Mo-99 in North America were spurred by supply disruptions as a result of aging foreign reactors as well as ongoing nonproliferation and domestic supply concerns.
NNSA has been funding work to minimize and eliminate the use of proliferation-sensitive highly enriched uranium (HEU) to produce Mo-99 and develop a U.S.-based production capability that has been absent since 1989. In 2010 the Canadian government announced that the NRU reactor, which supplies about 40 percent of the world supply of Mo-99, would cease routine production at the end of October 2016.
Mo-99 is used in approximately two-thirds of all nuclear medicine imaging procedures, amounting to roughly 50,000 diagnostic nuclear medicine procedures performed every day in the United States. Until recently, the entire U.S. supply of Mo-99 for nuclear medicine has been produced in aging foreign reactors using HEU targets. Maintenance and repair shutdowns of these reactors have significantly disrupted the supply of Mo-99 in the U.S. and much of the rest of the world.
May’s award from NNSA acknowledged his work supporting the Office of Material Management and Minimization’s Molybdenum-99 Program, and in the minimization of HEU in civilian applications. NNSA commended May for his efforts with uranium detection technologies and project management support that “has been critical to the significant progress made in the development of low enriched uranium fission-based molybdenum-99 production technologies.”
May accepted the award from Jeff Chamberlin, director of the NNSA Office of Conversion, and Rilla Hamilton, the NNSA Mo-99 program director, at the 2016 Mo-99 Topical Meeting in St. Louis last month.
About Los Alamos National Laboratory (www.lanl.gov)
Los Alamos National Laboratory, a multidisciplinary research institution engaged in strategic science on behalf of national security, is operated by Los Alamos National Security, LLC, a team composed of Bechtel National, the University of California, BWXT Government Group, and URS, an AECOM company, for the Department of Energy’s National Nuclear Security Administration. Los Alamos enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
