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 space-dependent kinetics of a strongly coupled multiregion cylindrical reactor were studied both theoretically and experimentally. A three-node model was used to calculate the kinetic response in the various regions and these results were compared with two-detector noise measurements. Reasonable agreement was obtained for predicted and measured transfer functions, power spectral densities, coherence functions, and alpha, the ratio of the effective delayed neutron fraction to the prompt neutron lifetime. Differences in the kinetic response of the various regions were clearly evident.
