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 potential flow model was developed to predict wind fields in complex terrain. In this model, wind vectors and airflows are estimated from a velocity potential function. It was found that the velocity potential function is obtained by combining threedimensional doublets at each grid point on a horizontal plane and a uniform stream parallel to the surface of the earth. The strengths of the doublets were expressed as a function of the terrain height at each grid point. Wind components at an arbitrary point were easily calculated from the potential flow model proposed. Consequently, this potential flow model is useful in estimating airflows, the convergence and divergence of the distances between streamlines, and the trajectories of radioactive plumes.
