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.

An exact analytical solution of the characteristic equation of homogeneous nonequilibrium two-phase (gas-liquid) flow using the drift-flux model and an approximate, highly accurate, analytical solution of the characteristic equation of inhomogeneous nonequilibrium two-phase flows for practically all flow patterns are presented. Based on the nature of the eigenvalues, in analogy with single-phase flow and previous work in two-phase flows, the homogeneous and inhomogeneous nonequilibrium sound speeds have been defined. The resulting expressions for the sound speed are studied in a wide range of steam/water system parameters of interest such as pressure, degree of thermal nonequilibrium, and void fraction, from which conclusions concerning their general behavior are drawn. Good agreement is obtained between theoretical predictions of the sound speeds and various experimental data.
