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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

At an unhealed 4 × 4 rod bundle air/water test facility, optical investigations of the entrainment behavior and countercurrent flow experiments were performed under a large variety of test conditions: flow duct geometry; internals (tie plate, bundle length, number of grid spacers, rod diameter); type of injection (different nozzles, porous sinter metal) different mass flux for air and water. In addition, several flooding models were compared with experimental data. It was found that the type of injection has only a weak influence, whereas the geometric conditions upstream of the narrowest flow area (presence of bundle and grid spacer) have an important effect on the flooding behavior. In addition, a comparison of the applicability of different flooding models shows that only the models based on dimensionless numbers expressed by superficial velocities show a good agreement with experimental data.
