O O ACI SUBSYSTEM 1 OR 2 MODULE REMOVED.

o DHV-3 OR DHV-4 NOT FULL CLOSED AND RCS PRESSURE >284 PSIG.

REDUNDANT INDICATION WHICH WILL VERIFY ALARM:

o DHV-3 VALVE POSITION INDICATION.

O DHV-4 VALVE POSITION INDICATION.

O RCS PRESSURE INDICATION.

OPERATOR ACTION FOR A VALID ALARM:

o INVESTIGATE CAUSE OF INCREASING PRESSURE.

O CLOSE DHV-3 AND/0R DHV-4 IF RCS PRESSURE >2B4 PSIG.

DISCUSSION:

o DHV-3 ACI USES RC-147-PT FOR RCS PRESSURE AND CAN BE SEEN ON THE REMOTE l

SHUTDOWN PANEL, OR SPDS o DHV-4 ACI USES RC-132-PT FOR RCS PRESSURE AND CAN BE SEEN IN ES CABINET #3.
