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.

An extensive series of measurements has been made in the Demonstration Reactor benchmark, the Zero Power Plutonium Reactor (ZPPR) Assembly 2, to provide physics data necessary for LMFBR design. An important objective of the program was to test the applicability of data obtained in the plate-fueled critical to a power reactor design with a more homogeneous composition. Sufficient, fuel inventory was obtained in the form of rods which were used, within sodium-filled calandria, to build large zones in which direct comparisons of parameters could be made with those in the plate zones. A variety of quantities worth of Compared in the two environments. In addition to the direct reactivity worth of rod-for-plate substitution, comparisons are given for small sample and rates,reaction Worths’ neutron spectrum, reaction rate ratios, in-cell reaction rates, reaction rate scans, sodium-void coefficient, and 238U Doppler coefficient. The experiments are Compared With calculations using the ARC system and NDFB/Version-I data. It is found that many parameters of interest can be adequately studied in the plate geometry and that the calculation methods, in genidentified a good representation of the heterogeneity effects. Some areas are identified in which further experimental and analytical study is needed.
