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.

The heat transfer characteristics for the case of laminar flow through a hexagonal channel have been determined for the following conditions: The uniform heat flux on any one side of the hexagon is identical to that on the opposite side, and may be equal to or different than those on the two adjacent sides; both the velocity and temperature profiles are fully established; the heat transfer from the walls may or may not be accompanied by simultaneous internal heat generation in the flowing fluid. Fundamental temperature solution and equations are presented which may be used to predict the temperature field, or to calculate the difference between local wall temperature and the bulk fluid temperature for a variety of cases. Methods of predicting the variation of local wall temperature are illustrated for several typical cases, including the case of uniformly distributed wall heat flux. For the latter case, it was found that appreciable temperature variation exists along the periphery of the hexagon. The circumferential variation of the local Nusselt number and the mean Nusselt number are also reported, with and without internal heat generation.
