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 ELM coils in ITER are used to provide control of Edge localized Modes (ELMs). These coils are located on the outboard side of ITER between the shield modules and vacuum vessel (VV) and are subject to high radiation levels. Detailed three-dimensional (3-D) models of the toroidal and poloidal legs of the ELM coils and manifolds, as well as homogenized first wall, shield, and VV components were created for the MCNP code. Neutronics calculations were performed to determine a variety of radiation damage parameters for the ELM coils as well as the VV located behind them. The results presented here include fast neutron fluence, insulator dose rate, He production, Cu dpa, and nuclear heating. VV heating and dpa are also presented. These results are being used to guide the evolving design of the ELM coils including thermal stress and thermal hydraulic analyses.
