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.

The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

Carbon- and silicon carbide (SiC)-based materials, especially in the form of composites, have attracted more attention from reactor technologists than have other ceramics because they better fulfill the prime requirements of reactor materials, such as high-temperature stability and low susceptibility to irradiation and nonbrittle fracture. These composites are fabricated through different routes and may vary in their properties. Therefore, sufficient data need to be generated on the microstructure and mechanical properties of these composites. In the studies reported here, carbon- and SiC-based fibrous ceramic composites were prepared using a liquid-infiltration sol-gel technique with carbon fibers as reinforcement and hybrid sol and pitch as matrix precursors. To some compositions, SiC nanoparticles were added. The composites were heated to 1000°C and 1500°C. The sol-gel route results in an amorphous mixed oxycarbide, silica, and carbon matrix, which on heat treatment at 1500°C is converted to a semicrystalline SiC matrix composite. Scanning electron microscope examination of carbon fiber/carbon and carbon fiber/SiC composites showed good wetting of fibers by matrix resin, forming good bonding at the interface. The carbon fiber/SiC composites with SiC nanoparticles as additional reinforcement showed higher density as well as a 34% increase in flexural strength compared with those without nanoparticles. The addition of just 1 wt% of SiC nanoparticles decreased oxidation by 4 wt%.
