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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

A model suitable for the prediction of gamma-ray spectra subsequent to the capture of neutrons into nuclear states of identifiable spin and parity has been developed. The dependence of radiative transition probabilities on the nuclear selection rules is explicitly accounted for. Means are provided for allowing dipole and quadrupole transitions in conjunction with variations in the magnitudes of corresponding transition “matrix elements.” Comparisons are given between experimental capture spectra and corresponding spectra calculated with varying assumptions with respect to pertinent nuclear parameters for two capture states of 28Al and one of 25Mg. A comparison of calculated spectra using fitted and crudely approximated cascade parameters for the 28Al capture states indicates few, if any, differences that would significantly change resultant neutron-capture gamma-ray-production cross sections.
