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.

Application of a θ-difference technique to the finite-difference solution of xenon-induced spatial transients has been made, which shows a substantial improvement in the accuracy of the calculated stability index and oscillation period. Virtually no correction is necessary for time-step lengths up to two hours, so an accurate simulation of experimental tests can be performed explicitly in the time domain with fairly crude time-step lengths. A simple expression was obtained for the optimum value of the parameter, θ, that can minimize the calculational error for a broad range of the core stability. The method is expected to be applicable for controlled xenon transients as well as for free-running oscillations.
