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.

The discovery of quasiaxially symmetric stellarators whose magnetic spectrum has approximate two-dimensional symmetry opens up the possibility of designing fusion reactors that have tokamak transport and stellarator stability. Prototypes with two or three field periods have asymmetries almost as small as the coefficients for a typical tokamak that are associated with ripple from the toroidal coils or helical excursion of the magnetic axis resulting from instability. We have found modular coils that are only moderately twisted and produce robust flux surfaces that do not deteriorate when changes are made in the magnetic field. This work is bolstered by recent stellarator experiments that have exceeded stability limits predicted by linear theory. The problem may be that force balance and stability are lost across islands if the equilibrium equations are not in conservation form.
