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.

Global MHD stability calculations using the PEST code have been carried out as part of the US ITER team's High Aspect Ratio Design (HARD) study. Approximately 15,000 cases have been evaluated both for global and local (ballooning) modes. In addition to aspect ratio variations [2.78 < A < 5], a range of shapes (1.4 < κ < 2.0, 0. < δ < 0.6) has been examined and the safety factor has been varied: q(0) was varied from 1.05 to 1.85 and qψ from 3.1 to 4.55. For global aspect ratio scaling, these results show no significant increase or decrease in the maximum Troyon parameter, within the level of variation imposed by profile differences: the scaling of the maximum Troyon parameter (g) is found to be independent of A, if optimal values are considered at each aspect ratio. Specific results for the HARD configuration (A = 4.0, κ = 2.0, δ = 0.4 and q = 3.1, 4) show that the grequired can be obtained with values of 1i(3) = 0.65 – 0.85 in both the ignition and steady state phases.
