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.

A neutron gauge for the accurate determination of high mean void fractions in a water-steam mixture has been designed to operate on the transmission of a thermal-neutron beam obtained with a 252Cf neutron source coupled with a polyethylene howitzer. Calibrations, carried out with a Plexiglas-air combination simulating annular flow and core flow, show that the gauge is characterized by high sensitivity and precision with respect to the other radiation techniques. Taking into account the lack of calibration standards and the wide range of water and steam densities generally involved in heat transfer processes, we developed a mathematical model of the gauge response to obtain adequate performances for practical use. The model, which is valid in principle for any flow regime, is specialized here for annular flow, which is of interest for the foreseen application in heat transfer studies on an out-of-pile test facility.
