A lot depends on what they want to hydro test, i.e. after the superheaters are installed assuming that each and ever super unit was individually hydro tested prior to installation, when that time comes. In other words, it could be many, many months yet.
The key point to remember is, the FRA "clock" starts running when the first flue/tube is installed, and they will be allowed one year "grace period", if I remember the rules correctly, until the first fire-up. That is when the 1472 days, 15 year, clock REALLY starts.
