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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

Dual-beam ion irradiation with Si- or Si and He ions was used to simulate expected fusion conditions. Indentation techniques were used to determine the changes in hardness, modulus and indentation fracture toughness in dual-ion irradiated -SiC at temperatures range from 673 to 1673 K. Ion irradiation clearly enhanced radiation induced hardening. Also, appreciable hardening by simultaneous helium injection revealed after dual-ion irradiation. The elastic modulus of the ion irradiated -SiC exhibited a slight decrease at low temperature irradiation, and a recovery at high temperature irradiated -SiC. The indentation fracture toughness increased after both single- and dual-ion irradiation for dose up to 1-3 dpa, then decreased for higher temperature and longer irradiation.
