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.

How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

The methods for nonresonant cell homogenization in plate-type fast reactor critical assemblies are discussed and tested against high order Sn transport calculations in one-dimensional geometry. The methods tested show satisfactory agreement with transport calculations. The TESS calculations with bilinear flux-adjoint weighting are slightly preferred over flux weighting with either TESS or CALHET fluxes. Two different treatments of the leakage in the cell calculation lead to slightly different heterogeneity effects when calculated by flux weighting, but very little difference when calculated by bilinear weighting. A two-dimen-sional test problem gave some surprising results (negative heterogeneity factor) and has raised some unanswered questions.
