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.

Digital control system installed at China’s Linglong One
Earlier this month, the first digital control system was put in place at Linglong One, a small modular reactor demonstration project being built at the Changjiang nuclear power plant in Hainan Province. This is the world’s first land-based commercial SMR and is controlled by China National Nuclear Power Co. Ltd., a subsidiary of the China National Nuclear Corporation (CNNC).

Tritiated stainless steel surfaces are shown to evolve tritiated species other than HTO and HT. These species are identified as being organic in nature and highly condensable on system walls. The source of the organics is viewed as being the hydrocarbon layer on the stainless steel surface. X-ray photoelectron spectroscopy of cleaned stainless steel surfaces indicate that a majority of the surface is covered by carbon. The carbon is bound predominantly in hydrocarbon groups. Engineering materials are expected to be sources of hydrocarbons awaiting tritiation. These volatile tritiated organics could have an impact on dosimetric calculations and on surface contamination of metals.
