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.

NSUF awards 19 Rapid Turnaround Experiments
The Department of Energy’s Office of Nuclear Energy has awarded 19 experimental proposals access to Nuclear Science User Facilities (NSUF) under the 2024 “third call” for Rapid Turnaround Experiment (RTE) projects. In total, the awards are valued at about $1 million and were granted to 19 principal investigators from 11 institutions, including universities and industry researchers.

The thermal conductivity, λ, of three samples of oriented fibrous carbon insulation of possible interest to fusion reactors was measured from 300 to 1300°K in a radial heat-flow apparatus. Samples of 0.18 g/cm3 density were prepared by a vacuum filtration process from carbon fibers and powdered phenolic resin and were characterized after carbonization. The λ of these low-density composites depended on both the heat treatment temperature and the fiber orientation. For samples heat treated at 1575°K, the room-temperature λ perpendicular to the planes of fibers was ∼0.5 mW/(cm °K) and was three times as high in the direction parallel to the planes. At 1000°K, the λ in both directions had doubled, primarily because of the positive dλ/dT of the amorphous carbon fibers. Material heat treated at 2775°K had a significantly higher room-temperature λ and a negative dλ/dT, indicating that a slight degree of ordering or graphiti-zation had occurred in the fibers during heat treatment. At high temperatures, the λ of all three samples increased markedly because of radiative heat transport.
