3.6.1.8 Each containment purge isolation valve shall be OPERABLE /

APPLICABILITY: Modes 1,2,3, and 4 ACTION:

With a containment purge isolation valve (s) having a measured leakage rate exceeding the limits of Surveillance Requirements 4.6.1.8 restore the inoperable valve (s) to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, otherwise be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE REQUIREMENTS 4.6.1.8 Prior to entering MODE 2 after each COLD SHUTDOWN, if not performed in the previous 92 days, each containment purge isolation valve with resilient material seals shall be demonstrated OPERABLE by measuring the leakage rate and verifying that when this measured leakage rate is added to the leakage rates determined pursuant to Specification 4.6.1.2.d for all other Type B and C penetrations, the combined leakage rate is less than or equal to 0.60 La.

In addition, the leakage rate for the containment purge valves shall be com-pared to the previously measured leakage rates for the same valve to detect valve degradation. An engineering evaluation shall be performed to determine what corrective action, if any, is necessary.

3/4.6.4 CONTAINMENT ISOLATION VALVES LIMITING CONDITION FOR OPERATION 3.6.4 The containment isolation valves specified in Table 3.6-2 shall be OPERABLE with isolation times as shown in Table 3.6-2.

APPLICABILITY: MODES 1, 2, 3 and 4.

ACTION:

With one or more of the isolation valve (s) specified in Table 3.6-2 inoperable, maintain at least one isolation valve OPERABLE in each affected penetration I that is open and either:

a. Restore the. inoperable valve (s) to OPERABLE status within 4 '

hour's, or '~'

b. Isolate .~e ch affected penetration within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> by use of at least one deactivated automatic valve secured in the isolation position, or

c. Isolate each affected penetration within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> by use of at .

least one c1csed manual valve or blind flange; or

d. Be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE REOUIREMENTS 4.6.4.1 The isolation valves specified in Table 3.6-2 shall be demonstrated OPERABLE prior to returning the valve to service after maintenance, repair  :

or replacement work is performed on the valve or its associated actuator, control or power circuit by performance of a cycling test and verification -

of isolation time.

3, 10 CONTAINMENT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) l 4.6.4.2 Each isolation valve specified in Table 3.6-2 shall be demonstrated 1 OPERABLE during the COLD SHUTDOWN or REFUELING MODE at least once per 18 months by:

a. Verifying that on a containment isolation test signal, each isolation valve actuates to its isolation position.

b. Verifying that on a High Radiation test signal, each containment purge valve actuates to'its isolation position.

4.6.4.3 The isolation time of each power operated or automatic valve of Table 3.6-2 shall be determined to be within its limit when tested pursuant to Specification 4.0.5.
