LIMITING CONDITION FOR OPERATION 3.6.3 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 that is open and:
: a. Restore the inoperable valve (s) to OPERABLE status within 4 hours, or
            *b. Isolate each affected penetration within 4 hours by use of at least one deactivated automatic valve secured in the isolation position, or
            *c. Isolate each affected penetration within 4 hours by use of at least one closed manual valve or blind flange; or
: d. Be in at least HOT STAJiDBY within the next 6 hours and in COLD SHUTDOWN within the following 30 hours.
SURVEILLANCE RE0VIREMENTS 4.6.3.1 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.
4.6.3.2  Each isolation valve specified in Table 3.6-2 shall be demonstrated OPERABLE during the COLD SHUTDOWN or REFUELING MODE at least once per 18 months by:
: a. Verifying that on a Phase "A" Isolation test signal, each Phase
                  'A' isolation valve actuates to its isolation position,
: b. Verifying that on a Phase "B" Isolation test signal, each Phase "B" isolation valve actuates to its isolation position, and
: c. Verifying that on a Containment High Radiation test signal, each purge supply and exhaust isolation valve actuates to its isolation position.
4.6.3.3 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.
        *The provisions of Specification 3.0.4 are not applicable.
