SONGS uses Plan B. I recall ANSI N323A -1997 allows up to annual calibrations, but I don't recall a " plus till the end of the month" addendum. For shorter cycles, I guess if your out of calibration/out of tolerance "As Found" fraction is low, you can use any odd number of total days you like.

Fermi - due date is end of the month. You could make the case for using the periodicity allowance in your TS / TRM for calibration / functional surveillance grace period, say +25% of calibration periodicity, thus semi annual / annual cals due at the end of month would be well within grace period. For those that use exact due date, what technical reference is used for basis?

The other plants in the FENOC fleet use the exact cal date plus frequency as a due date. What does your organization use? A. Due date at the end of the month? B. Exact due date (cal date + frequency)?
