• • Not required during periods of refueling shutdown, but must' be per't rmed prior to starting up if it has not been performed during the previous surveillance period.

o**During cold or refueling shutdown, a check of one pressure channel per steam generator is required when the steam generator could be pressurized.

• o**When used for the overpressure mitigating system each PORV shall.be demonstrated operable by:

a. Performance.of a channel functional test on the PORV actuation channel, but excluding valve operation,.within 31 days prior to entering a condition in which the PORV is required operable i and at least once per 31 days thereafter when the PORY is required operable.  ;
