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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Data from the Tandem Mirror Experiment (TMX) and other recent research show how to control plasma/wall interactions in tandem mirrors (TMs). Based on current knowledge, plasma/wall interactions will not limit the performance of TM reactors—either at the end walls or the radial walls. Magnetic field expansion and gas pumping can be used to regulate the plasma conditions at the end wall. Specifically, in TMX the plasma density at the end wall was found to be ≈2 × 109 em −3, whereas the end-plug density was ≈2 × 1013 cm−3; also, the sheath potential at the wall (8 V) was <10% of the end-plug electron temperature. The "natural divertor" effect-by which positively charged plasmas in magnetic mirror machines exhaust particles and energy to the end wall—can be used to both control the plasma conditions at the radial walls and divert impurities to the end wall. These techniques, the data that support them, and needed areas of further research are discussed.
