Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

A method of solving the time-energy dependent problem in reactor physics is explained. This method uses an iterative process to solve the steady-state Boltzmann equation and takes advantage of the implicit time variable concealed in this equation and released by the iterative calculations. Various examples of calculations are presented for fast and thermal reactors. They reveal some interesting features of kinetics neutron population and provide information for understanding reactor kinetics and time-of-flight spectra obtained both in fast and thermal subcritical systems.
