"Not that I don't agree that it's pretty crazy"
Well if that's how the Navy is, then that's how it is. I was MOS 55R in the army and that's not how how we do it. Then again I was not a 55G which (was) the nuke guys. Maybe they have excessive rules, maybe not.
As for n activation of (pure) water that either the O which is harmless or the H which is almost too obvious or playing games with contaminants. Nobody uses pure water as a coolant other than maybe training/experimental/university reactors, so there's the chemical shim system (and its inevitable contaminants). Or simple mechanical contamination like household dust essentially. Or corrosion (however slow) of non-bulk parts of the reactor, iron, carbon, and chromium from the walls are irrelevant but copper ions from slowly corroding cabling or something. Good luck being nearby the ocean and not having detectable chloride ion concentration, however low. Or dissolved nitrogen from the air, argon etc from the air. Sealing/gasketing material incredibly slowly corroding away. There's more to stainless steel than just Fe/C/Cr so if you corrode enough of it... Not much other options, its a pretty highly controlled area.
