164~ . 'l RANCHO SECO UNIT 1 I TECHNICAL SPECIFICATIONS l Limiting Conditions for Operation E.: Two independent Nuclear. Service Water subsystems shall be OPERABLE with each subsystem comprised of:

1. One OPERABLE Nuclear Service Cooling _ Hater (NSCH) loop.

2.. One OPERABLE Nuclear Service Raw Hater (NSRW) loop.

3. One OPERABLE Nuclear Service Spray Pond with:

a. A' minimum water level of 5'4",'and

b. A maximum water temperature of 95'F.

. Action Hith one Nuclear Service Hater subsystem inoperable, restore the inoperable subsystem to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT.

- F. Safety features valves and interlocks associated with each of the above systems are operable. Inoperable valves shall be.

placed in the saf?ety features position.

164-~ 3.3.2 .During power operation, hot standby, hot shutdown or startup conditions, the primary coolant system pressure isolation valves shall be functional hs follows:

1. All pressure isolation-valves listed in Table 3.3-1 shall be functional as a pressure isolation device, except as specified 164-- in 3.3.2.2. Valve leakage shall not exceed the amounts indicated.

2. In the event that integrity of any pressure isolation valve specified in Table 3.3-1 cannot be deinonstrated, reactor operation may continue, provided that at least two valves in each high pressure line having a non-functional valve are in i and remain 10 the mode corresponding to the isolated condition.(a>

164~- 3. If Specifications 3.3.2.1 and 3.3.2.2 cannot be met, a shutdown shall be initiated, the reactor shall not remain critical and shall be brought to a cold shutdown condition within an I additional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
