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.

Based on the Ringhals unit-1 stability test results, the coupling system TRAC/BF1-ENTRÉE has been benchmarked for predicting decay ratio and limit-cycle amplitude of the regional instability. The core was mapped into fewer CHAN groups based on the first azimuthal mode flux shape and the guidelines to minimize the numerical interregion stabilizing interaction. The system was further applied to detailed phenomenological studies. A symmetric pattern of the first azimuthal mode gave a dynamic boundary condition for ideal out-of-phase flow oscillations and lowers the regional instability threshold. The intermode interaction between the fundamental and first azimuthal modes was demonstrated under postulated large oscillations. Self- and mutual-modal reactivities were evaluated based on the higher modal flux shapes derived by ACCORD-N.
