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.

The engineering design of two high-power steadystate ECRH injection systems is presented for the MARS tandem mirror reactor. With a design power of 57 MW, System I is comprised of 1 MW cavity-mode gyrotrons coupled to a novel quasioptical launching system for the combination and transmission of the ECRH power to the plasma. System II has a design power of 84 MW and comprises 2.5 MW quasi-optical gyrotron units coupled to a quasi-optical launching system similar in principle to System I but displaying minimal space requirements. Potential operating conditions, parameters and constraints are presented for multi-MW gyrotrons and quasi-optical launching systems, and key ECRH development and technology needs for commercial tandem mirror reactors are defined.
