Why does the NRC have Commissioners?

I've been posting stuff regarding my attempts to get ECCS documents produced by Penn State since 1998. My Congressman was also stiff-armed by NRC. They sent him a copy of their earlier rejection of my request. As you may read in the last sentence, NRC tells me to go to federal court. Why do we have Commissioners if they will not act on my request?

I'll get back to my Congressman and tell him to get those reports and advise him that there should be no need for a request via FOIA.
