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.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

Radiation-induced isotopic equilibration in hydrogen gas containing tritium has to be accounted for when cryogenic distillation of hydrogen isotopes is used for their separation. In the absence of sufficient experimental data on the reaction kinetics an appropriate theoretical model is proposed. Unknown parameters of the model have been estimated with use of Möller-Plesset ab initio method. The results of calculations are in a reasonable agreement with certain experiments performed earlier by other authors. The dependencies of equilibration rate on temperature, pressure, and tritium molar fraction are established for isotope mixtures containing no impurities.
