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.

Based on the experimental data of total, nonelastic, elastic cross sections and elastic-scattering angular distributions for n + 58Ni reactions, a set of neutron optical model potential parameters is obtained in the region of incident neutron energy from 0.8 to 150 MeV. Then the reaction cross sections, angular distributions, energy spectra, gamma-ray production cross sections, and gamma-ray production energy spectra are calculated and evaluated by optical model, distorted wave Born approximation theory, Hauser-Feshbach theory, exciton model, and cascade mechanism inside nuclear. The results are compared with existing experimental data and other evaluated data from ENDF/B-VI and in agreement with each other within the uncertainties of these evaluations and measurements. Finally, the covariances for the important neutron cross sections are estimated using the SPC code based on the available experimental data.
