TABLE 3.6.3-1 (Continued)

PRIMARY CONTAINMENT ISOLATION VALVES TABLE NOTATION

" Isolates on injection signal, not primary containment isolation signal.

(a) See Specification 3 2, Table 3. 3. 2-4, for valve groups operated by isolation signal(s).

(b) Oe le ted.

(c) These valves are the RHR heat exchange s vent lines isolation valves. The vent line connects to the RHR safety relict valves (SRVs) Discharge Header before it penetrates the primary containment. The position indicators for these valves are provided in the Control Room for remote-manual isolation.

(d) Type C leakage tests not required.

(e) The associated instrument limes shall not be isolated during Type A test-ing. Type C testing is not required. These valves shall be tested in accordance with Surveillance Requirement 4. 6. 3. 4.

(f) These valves are check valves, located on the vacuum breaker lines for RHR SRVs discharge headers. The SRV discharge header terminates under pool water and therefore has no containment isolation valves other than those on lines feeding into it.'g) 2SLS"HOV5A and 8 are globe stop check valves. These valves close upon reverse flow. The motor operator is provided to remote manually close the valve from the control room.

(h) These valves are testable check valves. They close upon reverse flow.

. The air operator on each valve is provided only for periodic testing of the valve. These valves can only be tested against a zero d/p.

(i) Valves are maintained closed. The FPM lines are capped. Valves are Type C tested.

Not primary containment penetration isolation valves. These valves close on an isolation signal to provide integrity of "A" and "8" LPCI loops.

(k) Valves close on a SCRAM signal; not part of primary containment isolation system but are included here for 'Type C testing per Specification 3.6.1.2.

These valves are not required to be OPERABLE per this specification but are required to be OPERABLE per Specification 3. 1.3. 1.

Not subject to Type A or Type C leak test because of constant monitoring under constant 1800 psig pressure and the possible detrimental effects of shutdown.

(m) Not subject to Type C test per 10 CFR 50, Appendix J. A hyostatic test is performed in accordance with Speci fication 4. 6. 1. 2. d. 3.

(n) These valves are Type C tested and may be tested in the reverse direction.
