Strontium: Supply-and-demand success for the DOE’s Isotope Program
The Department of Energy’s Isotope Program (DOE IP) announced last week that it would end its “active standby” capability for strontium-82 production about two decades after beginning production of the isotope for cardiac diagnostic imaging. The DOE IP is celebrating commercialization of the Sr-82 supply chain as “a success story for both industry and the DOE IP.” Now that the Sr-82 market is commercially viable, the DOE IP and its National Isotope Development Center can “reassign those dedicated radioisotope production capacities to other mission needs”—including Sr-89.

A neutronics analysis for the MARS Li-Pb blanket and shield is presented. A thin blanket with a thick Fe-1422 reflector yields a tritium breeding ratio of 1.13 and an energy multiplication of 1.39. This blanket design has the attractive features of low cost, reduced activated waste, and ease of maintenance. A shield has been designed to provide adequate magnet protection.
