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 48.6-min isomeric state at 0.396 MeV in 111Cd can be excited by the neutron reactions 110Cd(n,γ)111mCd, 111Cd(n,′)111mCd, and 112Cd(n, 2n)111mCd. When natural cadmium is bombarded with fast neutrons, the influence of these reactions on the activation response varies according to the nature of the neutron spectrum. For a predominantly low-energy spectrum, the nonthreshold reaction 110Cd(n,γ)111mCd dominates, while for a relatively hard spectrum, the threshold reactions 111Cd(n,n′)111mCd and 112Cd(n,2n)111mCd are the most influential This situation offers interesting possibilities for utilization of elemental cadmium samples as neutron activation dosimeters in reactor applications. Accordingly, the elemental differential cross section for 111mCd excitation has been measured for cadmium over the energy range 0.135 to 10.01 MeV using activation techniques, and the response of this excitation function has been investigated for a standard fission-neutron spectrum. Some implications of these results for dosimetry applications are examined.
