ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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 procedure, described previously, for the preparation of high purity beryllium hydroxide has been improved and demonstrated on a kilogram scale, and a systematic study of its chemistry has been carried out. The Be(OH)2·xH2O starting material is dissolved in acetylacetone (HX) as BeX2, scrubbed with aqueous EDTA to remove metallic impurities, stripped with nitric acid, and precipitated with ammonia. The dried Be(OH)2 · 0.3 H2O, a granular, free-flowing powder, was obtained in 85% yield. Detectable metallic impurities totalled <5 parts/106. The variation of BeX+ and BeX2 formation quotients with ionic strength as well as the variation of BeX2 and HX distribution coefficients with both aqueous ionic strength and organic phase composition are summarized. Decontamination efficiencies for some 13 cations were estimated to be very high. Effective purification was demonstrated on a sample of Be(OH)2 starting material which was contaminated with 1000 parts/106 parts BeO of Na+, Mg2+, B(III), Cu2+, Al3+, Fe3+ and Cr3+.
