e. Core flood tank (CFT) vent valves CF-V3A and CF-V3B shall be' closed and the breakers'to the CFI vent valve motor operators shall be tagged open, except when adjusting core flood tank level and/or pressure 3.3.1.3

~

Reactor Building Spray System and Reactor Euilding Emergency Cooling System The following components must be operable:

a. Two reactor building spray pucps and their associated

-spray nozzles headers and two reactor building emergency cooling fans and associated cooling units (one in each train),

b. The sodium hydroxide tank level shall be maintained

at 8 ft. + 6 inches lower than the BWST level as measured by the BWST/NaOH tank level differential i indicator. The NaOH tank concentration shall be 10.0 + .5 weight percent (%).

c. All manual valves in the discharge lines of the sodium hydroxide tank shall be locked open.

3.3.1.4 Cooling Water Systems

a. Two nuclear service closed cycle cooling water pumps must be operable.

b. Two nuclear service river water pumps must be operable.

c. Two decay heat closed cycle cooling water pu=ps cust be operable,

d. Two decay heat river water pumps must be operable.

e. Two reactar building emergency cooling river water pumps must be operable.

3.3.1.5 Engineered Safeguards valves and Inter 1ceks Associated with the Systems in

specifications 3.3.1.1, 3.3.1.2, 3.3.1.3, 3.3.1.4 are operable, i

3.3.2 Maintenance shall be allowed during pcwer operation on any component (s) in the ~ makeup and purification, decay heat , E3 energency cooling water, RE spray, CFT pressure instrumentation, CFT level instrumentation, EWST level instrumentation, or cooling water systems which will not remove more than one train of each system from service. Components shall not be removed i from service so that the affected system train is inoperable for more than

72 consecutive hours. If the system is not restored to meet the f

requirements of Specifications 3.3.1 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, the reactor shall be l

l placed in a cold shutdown condition within twelve hours.

The iodine removal function of the reactor building spray system requires one spray pump and sodium hydroxide tank contents.

The spray system utilizes common suction lines with the decay heat removal system. If a single train of equipment is removed from either system, the i other train must be assured to be operable in each system.

]

hen the reactor is critical, maintenance is allowed per Specification 3.3.2 and 3.3.3 provided requirements in Specification 3.3.4 are met which assure operability of the duplicate components. The specified =aintenance times are a maximum. Operability of the specified components shall be based on the results of testing as required by Technical Specification 4.5.

An allowable maintenance period of up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> may be utilized if the operability of equipment redundant to that removed from service is demon-strated immediately prior to removal.

In the event that the need for emergency core cooling should occur, operation of one mal.eup pump, one decay heat removal pump, and both core flood tanks will protect the core. In the event of a reactor coolant system rupture their operation will limit the peak clad temperature to less than 2,300 F and the metal-water reaction to that representing less than 1 percent of the clad.

Two nuclear service river water pumps and two nuclear service closed cycle cooling pumps are required for normal operation. The normal operation require-ments are greater than the emergency requirements following a loss-of-coolant.
