If it had to do with the ORSE, 1—it would be a LOT more than just the CO going away, 2—there would be an even BIGGER story about compromising nuclear safety. Remember, the Houston leaked a little bit of water (probably from the DRT) and CNN, et al, went ape over it, despite the actual amount of radioactivity being quite literally next to nothing. If someone was falsifying check chemistry (which got another CO canned last year), they would have said as much.
I had the opportunity to serve with CDR Hill. This news comes with little surprise. I am sure the Commodore took action to stave off a modern day Mutiny on the Bounty.
