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.

To investigate the clogging of high-efficiency particulate air (HEPA) filters by soot during fire events, the Carman-Kozeny relation, which is an equation of pressure drop for fluid passing through a particle packed layer, has been applied to the pressure drop evaluation of fluid through the soot deposition layer on a HEPA filter. Particular attention has been paid to the characteristics of the soot and the compressibility of the soot deposition layer on the HEPA filter. It has been shown that the pressure drop of fluid through the soot deposition layer depends on the specific resistance and compression coefficient of the soot deposition layer as well as on the amount of soot deposited per unit area of HEPA filter and the filtration air flow velocity.
