1. Gland Water B Subsystem
1. SW-PS-388 GLAND WATER

<1 psig SYSTEM B

2.

SW Gland Water Subsystem B

2.

SW-PS-388 and LOW PRESSURE

<14 psig for 18seconds SW-REL-TR(B) timing out

3.

Loss of power to DPIS-1B

3.

None

1.

AUTOMATIC ACTIONS 1.1 SW-MO-2129, SW;GLD SEAL SUPP FROM LOOP B, opens if closed.

NOTE - Annunciator 1B/C-3, FPFLOW TO GLAND SEAL, alarming indicates SW-SSV-10 is de-energiZed/open.

1.2 SW-SSV-,0, FIRE PROTECTiON BACKUP TO SW PUMPS GLAND SEAL, opens when SW Gland Water Subsystem A of B < 14 psig plus an 18 second time delay.

.2.

OPERATOR OBSERVATION AND ACTION NOTE - If gland water supply from SW pump discharge prior to alarm, FP backup and Riverwell supplies are isolated.

2.1 If SW pump discharge supplying gland water at time of alarm and alarm due to low gland water system pressure:

2.1.1 Check, Gland Water Su'bsystem B 'for leaks.

2.12 If.Zurn Strainer B D/P > ý6 psid, ensure strainer in backwash operation.
