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.

Inconel 600,Inconel 625 and austenitic steel (AISI 304LN) surfaces were cleaned in UHV by laser pulses of 1J total energy. Residual surface contamination layers were dissociated and desorbed. The surface cleanness degree reached was equivalent to that obtained by conventional cleaning techniques like bulk heating and sputtering by ion bombardment. A comparison between these three techniques is presented. The laser cleaning efficiency was found to be strongly dependent on the initial surface contamination degree and on the residual gas composition. In particular the effect of laser shots on the activation of the surface oxidation process at ambient pressures of about 10−9 mbar of CO was studied. The possibilities of using the laser heating technique as a tool in plasma edge diagnostic (in situ cleaning of probes,analysis of trapped particles, redeposition measurements,…) in fusion devices is discussed.
