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 solutions to the one-dimensional energy-dependent Boltzmann equations for two different media are shown to possess such a full-range completeness property that an arbitrary function satisfying a Hölder condition can be expanded in terms containing solutions to both equations. These solutions are given by Leonard and Ferziger. This property makes it possible to solve energy-dependent neutron transport problems for two adjacent media. In comparison with half-space problems, one must solve two more inhomogeneous Fredholm integral equations. The scheme of the extension to multilayer system is also represented. In using the multigroup method, the series solutions of the Fredholm equations are rapidly convergent, if the energy dependences of the total cross sections in both adjacent media are roughly of the same form.
