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.

This talk will deal with the asymptotic diffusion limit of the multigroup neutron transport equations. (Previous asymptotic work on neutron transport has almost exclusively dealt with monoenergetic problems.) We show that the standard multigroup diffusion equations are asymptotic limits of the multigroup transport equations, but that other (much lesser known) asymptotic limits also exist that are physically relevant. The talk concludes with a discussion of the physical interpretation and possible applications of these results.
Thermal radiation transport simulations are difficult. Some of the challenges are purely technical, while some have to do with choices made for more because of historical reasons than rationality. This talk will cover a few examples of issues in thermal radiation transport calculations and the prospects for resolving them. I will also discuss some of the impact of these issues on multi-physics calculations, and give a few examples of possible terrestrial and extraterrestrial experiments that are relevant to improving thermal radiation transport models.
Warren “Pete” Miller, growing up on the South Side of Chicago, was a boyhood friend of Emmett Till, a 14 year-old boy lynched in Mississippi in 1955—an event that helped launch the Civil Rights Movement. This event had a lasting impact on Miller influencing his higher education, his career at Los Alamos National Laboratory and later endeavors. Miller was able to witness an improvement in ethnic diversity and inclusion over the decades of his life that made the U.S. a better place for all. The U.S. is presently at a cross roads. Will the future hold more progress in diversity and inclusion or a big step backwards?
