CONTAINMENT AND DRWELL ISOLATION VALVES

!B cm

$ NOTES

[ (a) Subject to a Type C leak rate test at a test pressure of 7.6 psig except as otherwise noted.

(b) Also isolates the drywell.

~

(c) Testable check valve.

(d) Isolates on MS-PLCS air line high flow or MS-PLCS air line header to Main Steam Line low differential pressure.

(*) Receives a remote manual isolation signal.

II) This line is sealed by the penetration valve leakage control system (PVLCS). The combined leakage from

{ valves sealed by the PVLCS is not included in 0.60 La Type B and C test total.

i (9) This valve sealed by the main steam positive leakage control system (MS-PLCS). Valves sealed by the O MS-PLCS are tested in accordance with Surveillance Requirement 4.6.1.3.f to verify that leakage does not exceed the limit specified in Specification 3.6.1.3.c. This leakage is not included in the 0.'60 La Type B and C test total.

(h) Not subject to Type C leakage tests. Valve (s) will be included in the Type A test.

(I) Valve is hydrostatically leak tested at a test pressure of 8.36 psig (1.1 Pa). The leakage from hydrostatically tested valves is not included in the 0.60 La Type B and C test total.

( ) Not subject to a Type A, B, or C leak rate test.

(I) Valve groups listed are designated in Table 3.3.2-1.
