TABLE 3.6.3-1 PRIMARY CONTAINMENT ISOLATION VALVES NOTATION NOTES (Continued)
- 15. Check valve used instead of flow orifice.
- 16. Penetration is sealed by a flange with double 0-ring seals. These seals are leakage rate tested by pressurizing between the 0-rings. Both the TIP Purge Supply (Penetration 35A) and the TIP Drive Tubes (Penetrations 35C thru G) are welded to their respective' flanges.
Leakage through these i
seals is included in the Type C leakage rate total for this penetration.
The ball valves (XV-141A thru E) are Type C tested.
It is not practicable to leak test the shear valves (XV-140A thru E) because squib firing is required for closure. Shear valves (XV-140A thru E) are normally open.
17.
Instrument line isolation provisions consist of an excess flow check valve.
Because the instrument line is connected to a closed cooling water system inside containment, no flow orifice is provided. The line does not isolate during a LOCA and can leak only if the line or instrument should rupture.
Leaktightness of the line is verified during the integrated leak rate test (Type A test).
18.
In addition to double "0" ring seals, this penetration is tested by pressurizing volume between doors per Specification 4.6.1.3.
- 19. The RHR system safety pressure relief valves which are flanged to facilitate removal will be equipped with double 0-ring seal assemblies on the flange closest to primary containment. These reals will be leak rate tested by pressurizing between the 0-rings, and the results added into the Type C total for this penetration.
- 20. See Specification 3.3.2, Table 3.3.2-1, for a description of the PCRVICS isolation signal (s) that initiate closure of each automatic isolation valve.
In addition, the following non-PCRVICS isolation signals also initiate closure of selected valves:
1 EA Main steam line high pressure, high steam line leakage flow, low j
MSIV-LCS dilution air flow.
LFHP With HPCI pumps running, opens on low flow in associated pipe, closes when flow is above setpoint.
LFRC With RCIC pump running, opens on low flow in associated pipe, closes when flow is above setpoint.
LFCH With CSS pump running, opens on low flow in associated pipe, closes when flow is above setpoint.
LFCC Steam supply valve fully closed or RCIC turbine stop valve fully closed.
All power operated isolation valves may be opened or closed remote manually.
