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 alloy containing niobioum-20 w/o uranium has been developed for reactor fuel applications. The fabrication characteristics, mechanical properties, and corrosion behavior in air, CO2, NaK, water, and steam were studied. After consumable arc melting, the alloy was successfully forged at 1370°C (2500°F) and rolled at 980°C (1800°F) to sheet. Representative specimens of this alloy showed onlv slight reductions in hardness up to 900°C (1650°F). The 0.2% offset yield strength was 93,000 psi at 24°C (75°F) and 71,000 psi at 870°C (1600°F). At a stress of 63,000 psi at 870°C (1600°F), 200 hr were required to cause rupture. The corrosion life of niobium-20 w/o uranium was superior to that of unalloyed niobium in 300°C (572°F) air and in CO2 at 316°C (600°F). In 1000 hr of exposure to 316°C (600°F) water, this alloy exhibited corrosion rates only two or three (0.003 mg/cm2/hr) times greater than that of Zircaloy-2 (0.001 mg/cm2/hr). This alloy appears to be compatible with NaK at 870°C (1600°F.)
