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.

There are three components which contain tritium in the air, i.e. water vapor, molecular hydrogen and methane. However, there is no tritium monitor, which is able to measure the concentration separately. In the light of it, we are developing a new monitor, which will be enable us to measure the tritium concentrations in two of these species, i.e. molecular hydrogen and methane. The specific activities of tritium in molecular hydrogen and in methane are very high. Then if we can collect the hydrogen and the methane, we will easily measure the tritium concentrations. We have conceptually designed a new tritium monitor and carried out several basic experiments. Based on the results of these experiments, we have estimated the performance of the monitor. For an hour counting, the monitor will be able to measure the tritium concentrations of molecular hydrogen and methane using about 4m3 air. Since the total performance of the monitor mainly depends on the capability of the proportional counter, we are developing an appropriate counter.
