Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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?
