It all depends on the individual line scores that determines whether you can be a nuke or not...
I have had an applicant that scored a 85 that I could not make a nuke and I have had a guy cut a 62 that made it in...
a 62??? How is that possible... good at math, terrible (!) at english?

I also dont recall him saying he was an expert, merely conveying his experience.
Anywho, here are the MINIMUM scores required.
VE+AR+MK+NAPT = 290 (with minimum 50 NAPT score)
or
AR+MK+EI+GS+NAPT = 290 (with minimum 50 NAPT score)
or
VE+AR+MK+MC = 252 (No NAPT required)
or
AR+MK+EI+GS = 252 (No NAPT required)
