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 for determining stabilizing control functions for any first-order controllable system is presented. Examples of stabilizing feedback control are examined and corroborated for stability using the second method of Liapunov. Consideration of a general class of arbitrary degree stabilizing feedback-control functions reveals that linear feedback control produces the greatest damping. Examination of signal error and time delay in the control function shows that highly damping control can result in system oscillation. Finally the method is extended to systems of higher order and a stabilizing control function is found for the reactor-kinetic equations even with unmonitored delayed neutrons if the linear feedback-control gain is > β/l.
