ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Molten stainless steel at ∼1720°C and melts of iron and alumina or 54 wt% UO2, 16 wt% ZrO2, and 30 wt% stainless steel at 2400 to 2800°C were poured onto 0.95- to 7.62-cm-thick steel structures. The melts rapidly penetrated these structures, probably by a thermal ablation process. Coatings of 0.2- to 2-mm-thick urania on the surfaces of the steel delayed penetration by the very high-temperature melts. Data from tests involving melts impinging on steel structures could be correlated by the single-parameter, empirical expression A finite difference model of the experiments is described. The model is used as the basis for predicting the extent of crust formation when melts contact cold steel and to suggest that a gas gap may form between the steel and any crust of frozen material that does form.
