ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.”

In this work the analysis of the effects of the poloidal currents flowing on the cooling piping of the divertor armour tiles is carried out. To deal with the complexity of the problem a parametric solving scheme, starting from the nominal plasma current value, was adopted to contemplate the great variability of the possible cases deriving from the experimental data base and to compensate the lack of knowledge due to the not well assessed theory on the plasma wall interaction. Further to overcame the difficulties in modeling the real design of the piping with the necessary spatial resolution to individuate the local current concentration areas the methodology illustrated here is based on shell interfaces for solving either the electric and the mechanical problem. This approach proved to be capable to highlight the critical design areas and was useful to suggest the relative remedial corrections.
