REACTOR COOLANT SYSTEM POWER OPERATED RELIEF VALVES LIMITING CONDITION FOR OPERATION 3.4.13 Two power operated relief valves (PORV's) shall be OPERABLE, with their setpoints selected to the low temperature mode of operation.

APPLICABILITY:

MODES 4g and 5*.

(a)

With less than two PORV's OPERABLE and while at Hot Standby during a

planned cooldown, both PORV's will be returned to OPERABLE status prior to entering the applicable MODE unless:

1)

The repai rs cannot be accomplished within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the repairs cannot be performed under hot'conditions, or 2)

Another action statement requires cooldown, or 3)

Plant and personnel safety requires cooldown to Cold Shutdown with extreme caution.

(b)

With less than two PORV's OPERABLE while in COLD SHUTDOWN, both PORV's will be returned to OPERABLE status prior to startup.

SURVEILLANCE RE UIREMENTS 4.4.13 The PORV's shall be verified OPERABLE by:

ll a)

Verifying the isolation valves are open when the PORV's are reset to the low temper ature mode of oper ation.

b)

Performance of a CHANNEL FUNCTIONAL TEST of the Reactor Coolant System overpressurization protection system circuitry up to and including the relief valve solenoids once per refueling outage.

c)

Performance of a CHANNEL CALIBRATIONof the pressurizer pressure sensing channels once per 18 months.

gReactor Coolant System cold leg temperature below 275'F.

• PORV's are not r equired at Reactor Coolant System temperatures below 165'F when all HPSI'umps and respective injection or header isolation valves are disabled and if a pressurizer bubble is formed with a pressurizer liquid level less than or equal to 4(@.

PORV's are also not required below 140'F when RCS does not have pressure boundary integrity.
