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.

In order to separate and store tritium (T) in the nuclear fusion cycle, we investigated the use of a hydrogen storage alloy which is safer and more easily handled than other materials, especially uranium. The solid solution alloy TiCr0.4V1.2Fe0.4 was chosen for the investigation because it resists pulverization and is easily activated. Using this alloy, we measured the storage volume, the equilibrium pressure and the isotope effect of absorption and desorption reactions in a low (10−2 ~ 102 Pa) hydrogen atmosphere pressure. The alloy had an absorbing volume of H/M = 0.5 by atomic ratio and the equilibrium absorbing pressure was almost the same as uranium's at the same ambient temperature. The equilibrium reaction has no isotope effect, but the reaction velocity between H2 and the alloy was twice that between D2 and the alloy. Even after several hundred repetitions of hydrogen absorption and desorption, still no change in the alloy was observed.
