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 reactor attributes of the compact, high beta RFP are as needed today as when the RFP was conceived. Confinement is a dominant scientific issue at present, In the past several years magnetic fluctuations have been shown experimentally to drive anomalous transport. From an understanding of the cause of transport, it is expected that flattening of the current density profile should suppress fluctuations and transport. Inductive current profile control has succeeded in reducing fluctuations, and doubling the energy and particle confinement times. For steady state current profile control, electrostatic current injection (dc helicity injection) is under preparation and rf current drive (fast wave and lower hybrid) has been shown to be feasible.
