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.

Activation data are needed for many evaluations concerning fusion reactors and, in particular, safety and environmental impact assessments. A stepwise description of the activation analysis process is given. A neutron source description for one-dimensional neuronic models is compared with that for three-dimensional models. Concerning neutron flux calculations, the choice between one-dimensional deterministic codes and three-dimensional Monte-Carlo codes is examined, taking into account their interface with activation codes. A reliable inventory code and an updated activation library are essential to obtain good activation data: The problems in the modeling of either pulsed irradiation or operation at different flux levels are tackled. The analysis and comparison of activation calculations for two different machine concepts [the Next European Torus (NET)/International Thermonuclear Experimental Reactor (ITER) and Ignitor], are carried out, showing how pulsed irradiation affects the results in the two cases and the main differences between the two analyses. As an example of the application of inventory calculations, a classification of NET/ITER and Ignitor materials into waste categories is proposed and discussed.
