I had to do some Googling, but the PPRA treaty would appear to explain the valve cover inspections: http://dtirp.dtra.mil/tic/synopses/ppra.aspx

Still looking for what would apply to the Navy reactors.

That's great to read, thanks! I imagine the experience earned on verifying the PPRA will be valuable when a verification mechanism for the FMCT is designed.
