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 estimating the average void fraction in water-moderated power reactors is presented. The method might be useful to determine departure from normal boiling conditions or nucleate boiling in boiling and pressurized water reactors, respectively. A standing acoustic wave is introduced in the core and the neutron density is measured, squared, time-averaged, and compared with the same quantity without an acoustic wave. The ratio is inversely proportional to the sixth power of the acoustic velocity; and the acoustic velocity depends on the average void fraction in the core. Consequently, this ratio is very sensitive to the average void fraction in the core.
