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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Sulfur is an important element in some food chains and the release of radioactive sulfur to the environment must be closely controlled if the chemical form is such that it is available or potentially available for entering food chains. The presence of 35S in the coolant gas of the Windscale Advanced Gas-Cooled Reactor (WAGR) warranted a study to assess the quantity and chemical form of the radioactive sulfur, in order to estimate the magnitude of the potential environmental hazard that might arise from the release of coolant gas from civil advanced gas-cooled reactors. A combination of gas chromatographic and radiochemical analyses revealed carbonyl sulfide to be probably the only 35S compound present in the coolant gas of the WAGR. The concentration of carbonyl sulfide was found to lie in the range 40 to 100 X 10-9 parts by volume and the 35S specific activity was ∼740 X109 Bq· kg-1 (20 mCi/g). The 35S appears to be derived from the sulfur and chlorine impurities in the graphite although other sources cannot be ruled out. Carbonyl sulfide labeled with 35S can be prepared in the laboratory from KCN 35S.
