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.

Fabrication milestone for INL’s MARVEL microreactor
A team from Idaho National Laboratory and the Department of Energy’s Office of Nuclear Energy (DOE-NE) recently visited Carolina Fabricators Inc. (CFI), in West Columbia, S.C., to launch the fabrication process for the primary coolant system of the MARVEL microreactor. Battelle Energy Alliance (BEA), which manages INL, awarded the CFI contract in January.

A sample counting cell for monitoring ultralow-level 85Kr in environmental air samples has been designed. The cell consists of ∼10 g of hydrogen mor-denite covered with 0.075-mm aluminum foil. The 85Kr is adsorbed by the hydrogen mordenite inside the counting cell. The radioactivity of 85Kr in the cell is measured by a modified external gas flow proportional counter. A refined separation method for the purification of 85Kr in the air sample has also been developed. The low detection limit for this improved counting system, including the refined separation procedure, is ∼0.02 pCi/cm3 based on 50-ℓ air samples at 1 atm. This counting method is also compared in detail with other methods.
