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.

Using a relatively simple static model and allowing a number of additional radiation shields in an axially symmetric hohlraum having two converters, a systematic process of reducing the asymmetry of the radiation field on a fusion capsule is presented. As a result of this procedure, a hohlraum target is obtained that shows a high degree of symmetrization even in a very early stage of irradiation. The sensitivity of the symmetry to the form and the position of each hohlraum component is investigated. To increase the reliability of the results, an enhanced model of radiation reemission in a hohlraum target, including reemission of the converter, is developed. Using this enhanced model it is found that the obtained hohlraum configuration is still valid, while the simple reemission model leads to incorrect results in special cases. It is also shown that the detailed configuration of a hohlraum target, especially of the radiation shields, depends considerably on the temperature distribution of the converter surface, but it is always possible to achieve a high degree of symmetry with radiation shields.
