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.

State legislation: Colorado redefines nuclear as “clean energy resource”
Colorado Gov. Jared Polis signed a bill into law on Monday that adds nuclear to the state’s clean energy portfolio—making nuclear power eligible for new sources of project financing at the state, county, and city levels.

Beryllium will be used as a plasma-facing material for the ITER first wall. It is expected that erosion of beryllium under transient plasma loads such as the edge-localized modes (ELMs) and disruptions will determine the lifetime of the ITER first wall. The results of recent experiments with the Russian beryllium of TGP-56FW ITER grade on the QSPA-Be plasma gun facility are presented. The Be/CuCrZr mock-ups were tested by deuterium plasma and radiative streams both with pulse duration of 0.5 ms and heat loads of 0.5 and 0.4 MJ/m2, correspondingly. Experiments were performed at 250 °C. The beryllium mock-ups were exposed to up to 100 shots. After 10, 40 and 100 shots, the evolution of surface microstructure and crack morphology were investigated as well as beryllium mass loss under the erosion process. The deuterium retention in erosion products was also studied by the thermal desorption method.
