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 discrete ordinate transport equation in two dimensions equivalent to the PL approximation is derived to eliminate the ray effect in the ordinary discrete ordinate equations. The number of the discrete ordinates, or the number of unknown functions of this discrete ordinate equation, is equal to that of the PL equations. Since it is also possible to obtain boundary conditions equivalent to those of the PL approximation at the interface of mediums or at the free surface, we can obtain a solution identical to that of the PL equation.
