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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

To correctly specify the composition and spectra of transmitted heavy-ion radiation fields, such as those encountered in space radiation protection studies, accurate values of the total, elastic scattering, reaction cross sections, and spectral and angular distributions of all emitted particles (nucleons, light ions, and heavy ions) from the nuclear interactions of propagating high-energy heavy-ion particles with target nuclei are required. For space radiation protection studies, this means that double-differential (energy and angle) isotope production cross sections must be known for all stable nuclear isotopes with mass numbers from 1 to about 60 colliding with any target nucleus at energies from tens of mega-electron-volts per nucleon up to several giga-electron-volts per nucleon. Currently there are several radiation transport codes that transport high-energy nucleons, light ions, heavy ions, or some combination of them. None, however, transport all of these particles in more than one dimension. In order to make a comprehensive tool for space applications that transports all of these particles, with a wide range of energies and in three dimensions, the database described above is needed, particularly for light and heavy ions. This paper discusses the creation of this comprehensive cross-section database.
