First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The China Fusion Engineering Test Reactor (CFETR) is the next tokamak device in China to bridge the gaps between ITER and the DEMOnstration nuclear fusion reactor (DEMO). The CFETR vacuum vessel (VV) was designed to remove nuclear heating, provide safety shielding, and maintain a high-quality vacuum environment. Seismic load is considered one of the most relevant accidental events affecting the structural integrity of the VV. In order to investigate the resistance of the CFETR VV against seismic load, finite element models of the VV were built. In this paper, equivalent static and response spectrum analyses were carried out to calculate displacements and stress fields aiming to check the response of the CFETR VV against a foreseen seismic load. The resulting stresses are lower than the allowable limits and satisfy the design requirements.
