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.

Experimental yields, both independent and cumulative, of fission products from thermal-neutron fission of 235U, were combined with semi-empirical model values for those yields for which experimental data were lacking. Using weights determined from experimental errors, or from a priori estimates for model values (which weights were uniformly lower than those for experimental values), and imposing the constraint that cumulative yield is a sum of independent yields of precursors, a most likely consistent set of yields and their errors was determined. The errors were adjusted upward in all cases for which the inferred consistent yield differed by more than its error from the ENDF/B-IV value. Using these yield errors, the sensitivity of decay power to yield uncertainty was determined both for a fission pulse and for very long, low-flux irradiation.
