35a 3.6.2 Containment Isolation Valves Applicability: Applies to the containment isolation valves listed in Table 3.6.2-1 for MODES 1, 2, 3, and 4.
Objective:
To provide assurance that containment isolation will function.
when initiated by appropriate sensors.
Specification: A. The containment isolation valves specified in Table 3.6.2-1 shall be OPERABLE.
B. With one or more of the isoaltion valve(s) specified in Table 3.6.2-1 inoperable, maintain at least one isolation valve OPERABLE in each affected penetration that is open and either:
- 1. Restore the inoperable valve(s) to OPERABLE status within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, or
- 2. 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 deactivated automatic valve secured in the isolation position, or
- 3. 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 closed manual valve or blind flange, or
- 4. 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 />.
Basis:
The OPERABILITY of the containment isolation valves ensures that the containment atmosphere will be isolated from the outside environment in the event of a release of radioactive material to the containment atmosphere or pressurization of the containment. Containment isolation ensures that the release of radioactive material to the environment will be con sistent with the assumptions used in the analyses for a LOCA.
The isolation valves of the Sphere Purge Air Supply and Air Outlet lines have not been demonstrated capable of closure under the differential pressures generated by a design basis accident. For this reason, containment isolation in these lines shall be maintained. This configuration shall be accomplished by locking closed manual isolation valves CVS-301 and CVS-313 of these lines. These valves shall remain locked closed during MODES 1, 2, 3, and 4 until they can be demonstrated capable of performing their containment isolation function under post accident conditions.

These valves do not receive an automatic containment Isolation signal.
They are operated by remote manual switch (RMS).
- Manual valves CVS-301 and CVS-313 of the Sphere Purge Air Supply and Air Outlet lines, respectively, shall be locked closed during MODES 1, 2, 3 and 4 in order to ensure that the containment purge lines maintain containment isolation.
