It do not believe that it is recognized by all utilities. It is called the NUF, BTW. It is basically the old NEU, with a new question database. Nothing like the DOE CORE. As much math as before, be able to do point, line and plane sources.. as well as A/S calculations, half lives and shielding calculations. (Of course, I haven’t taken it since 1999, before they changed it, so what do I know).
Also, there is no poll in your poll, instead of options, you asked two questions. Please delete the "Poll" option from this message, as it is not a poll one can answer with the poll option.
