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 design of engineered safety systems is primarily based on analytical predictions of the behavior of a reactor under accident conditions and on the result of relevant small-scale experiments. Within this frame, the analytical simulation of two-phase flows plays an important role. It serves as a model law for the extrapolation of small-scaled experimental results over magnitudes of scaling as well as for the detailed interpretation of involved physical processes. A careful description of the technical conditions of an experiment is mandatory for making two-phase flow analytical simulations a successful tool for transforming small-scale experimental results into design decisions for large power reactor systems.
