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.

Liquid-metal flow in the presence of a transverse magnetic field and gravity field was analyzed in a square-cross-section straight duct and a curved bend. The duct had conducting vanadium walls, and lithium coolant was used. Magnetohydrodynamic (MHD) equations with gravity field in three dimensions were developed in the modified toroidal coordinate system. The coupled set of equations was solved using finite difference techniques and an extended SIMPLER algorithm approach. Calculation of MHD pressure drop was made in the presence of a transverse magnetic field and a gravity field for a straight duct and a magnetic field varying as Bo(R + x)-1 in the transverse direction and a gravity field for a curved bend. The results for a straight duct indicate that the MHD pressure drop increases with the increase of magnetic field strength. The MHD pressure drop when fluid flows against the gravity field is greater by an amount that equals the product of the density of the fluid and acceleration due to gravity. The results for a curved bend indicate an axial MHD pressure drop. The axial MHD pressure drop in a curved bend increases with an increase in the magnetic field strength. It is also found that the MHD pressure drop in the presence of a gravity field is slightly higher than the MHD pressure drop without a gravity field.
