demand for nuclear engineers

I was just on the phone with a recruiter and they said if i got a 75 asvab, I could be a nuclear engineer. I called to join nrotc, I am not done with college nor does my university offer nrotc. they said i would have to change schools which i dont want to do. My question is what the demand is for nuclear engineers ? Why even do nrotc if I will have a electro optical engineering bachelors degree, if its so in demand couldn't i just get an officer job right away without doing nrotc? He said theyre "highly in demand " pretty sure hes lying.
