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.

Ariz. governor vetoes “fast track” bill for nuclear
Gov. Katie Hobbs put the brakes on legislation that would have eliminated some of Arizona’s regulations and oversight of small modular reactors, technology that is largely under consideration by data centers and heavy industrial power users.

Four different methods for the conversion of UF6 to ceramic grade UO2 powder have been developed to an industrial scale. Two of them, the ADU and AUC processes, are based upon precipitation of uranium compounds from aqueous solutions. The other two follow a dry route in which UF6 is decomposed and reduced by steam and hydrogen in either fluidized beds or rotating kilns. The quality requirements for the conversion products, UO2 powder, are closely related to the quality of the sintered pellets. An important requirement is the influence of the conversion process and its process parameters on sintered density. The aqueous AUC process is attractive, particularly if UNH is also to be processed. The dry processes are, however, expected to become of increasing importance. Rotating kilns have some favorable features as compared to fluidized beds.
