Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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 final disposal of high-level radioactive waste in a salt dome affects the thermomechanical behavior of the surrounding rock salt due to the temperature rise caused by the heat generation of the radioactive waste. The long-term safety analysis of the nuclear waste repository requires laboratory studies, in situtests, and the use of numerical calculations to predict the thermomechanical effects in the near and far fields of the repository. The near-field thermomechanical phenomena around several in situtemperature tests and a 300-m-deep conceptual borehole were studied numerically. Thermally induced closure of the boreholes and the strain-stress field distribution in the rock salt following the pressure load on the measuring probe surface and on the waste containers were determined. The calculations were performed with the commercial finite element program ADINA, taking into account the nonlinear and time-dependent behavior of the rock salt. The purpose of these investigations was a validation of the numerical methods, of the thermomechanical material parameters of rock salt, and of the model boundary conditions. The agreement between the results of the calculations and the measured values has shown that a relatively good prediction can be made of the thermomechanical effects in the near field of a waste disposal area with the numerical methods and the material laws used.
