TABLE 3.6-2 CONTAINMENT ISOLATION VALVES 3/4 6-17 AMENDMENT NO. 48, 55, 76, 77 , 98 TABLE NOTATIONS (1) Actuation Signals:
MSIS - Main Steam Isolation Signal SIAS - Safety Injection Actuation Signal HDP - High Differential Pressure Between Containment and Annulus RAS - Recirculation Actuation Signal CSAS - Containment Spray Actuation Signal EFAS - Emergency Feedwater Actuation Signal CIAS - Containment Isolation Actuation Signal CADP - Containment-Ambient Differential Pressure Signal CPIS - Containment Purge Isolation Signal (Class 1E Radiation Monitors)
(2) Valve does not receive CIAS, however a MSIS is considered a containment isolation signal for the purposes of actuation mode. (3) Manual Override Provided - CIAS is available but not credited for automatic isolation.
(4) Containment Isolation Valves whose safety function is to open / remain open post accident are also capable of being closed for containment isolation should that system no longer be required to operate post accident. (5) A CSAS is considered a containment isolation signal for the purpose of actuation mode (DRN 02-0736, Am. 55)
(6) Relief valve lifts to protect against overpressurization of the penetration. (DRN 02-0736, Am. 55)
(DRN 02-1809, Am. 76)
(7) Valve does not receive CIAS, since the valve does not have an automatic containment isolation function. The valve, normally cl osed, receives a SIAS to close to allow suction from the RWSP. The valve under normal conditions may be opened or closed manually. The valve opens on a RAS to allow suction from the SI sump. After RAS initiation, the valve may be closed remotely and manually to isolate any postulated Emergency Core Cooling System (ECCS) passive leakage.
(DRN 02-1809, Am. 76)
(DRN 03-667, Am. 77)
(8) The opening of locked or sealed closed containment isolation valves or deactivated automatic containment isolation valves o n an intermittent basis under administrative control includes the following considerations: Stationing an operator, who is in constant communication with the control room, at the valve controls. Instructing this operator to close these valves in an accident situation. Assuring that environmental conditions will not preclude access to close the valves and that this action will prevent the release of radioactivity outside the containment. (DRN 03-667, Am. 77) (DRN 05-39, Am. 98)
(9) Valve is not credited for Containment Isolation safety function. Valve receives actuation signal(s) to isolate to prevent inventory loss degrading Steam Generator heat removal and release of radioactivity outside of containment. Tech Spec 3.6.3 is entered if this valve is decla red inoperable. (DRN 05-39, Am. 98)
