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.

In this paper, we point out that data from earlier experiments carried out to measure beta-strength functions for short-lived fission products can also be used to provide average beta- and gamma-decay energy values for these nuclides. In our evaluation of decay data for the ENDF/B-V fission product file, we have used this approach as a means of deducing average decay energy values for a number of these isotopes for which experimentally based average values would otherwise not have been available. The methods employed are discussed, and the results for the average beta-decay energies per decay, <Eβ>, are presented. Where available, <Eβ> values deduced from decay scheme studies and from direct beta-spectrum measurements are given for purposes of comparison. Evidence is presented that suggests that the conventional decay scheme studies may not be a reliable source of average decay energy data for nuclides with large Qβ values. We propose that different types of experimental measurements, possibly involving total absorption techniques (of which the beta-strength work treated here might be considered as one example), may provide a better means of producing this important information.
