Yes, mode 6 is "refueling", but we've been core-empty for internals inspection for longer than expected. During which time we move into "core-empty" or "no-mode", it seems to be some new manager-speak to differentiate whether we've got fuel in the pot, or not?
I'd never heard "no-mode" until a few years ago, the term just kind of cropped up. It may be unique to TVA. As the saying goes "We do stupid good, but we're getting better at it".
Officially we are 120 hours or so behind schedule. There is a whole lot of work going on to modify the fire protection system that is holding up other work. As soon as the path gets cleared, we're going to be running like scalded dogs to get her back together. Managers are already starting to get megawatt fever no that they hear that fuel is moving again. So now is really the time to SLOW DOWN and ensure were doing it right, rather than right now.
