DISCUSSION:

1HIS ALARM MAY INDICATE THE ACI SETPOINT IS BEING APPROACHED (ABOUT 250#)

IF THIS IS OCCURRING THEN THE OPERATOR SHOULD REDUCE RCS PRESSURE.

CARE Sr.0ULD BE TAKEN AS TO NOT OVERPRESSURIZE THE DECAY HEAT SYSTEM.

o DHP-1B SUCTION TEMP. INDICATOR, DH-6-TI2 INDICATES HIGH O\

OPERATOR ACTIONS FOR A VALID ALARM:

o VERIFY PROPER "B" DC SYSTEM OPERATION BY CHECKING DC SURGE TANK LEVEL, DC PUMP RUNNING AND DC CONTROL VALVES SETPOINT NORMAL.

o-VERIFY PROPER DC RAW WATER OPERATION BY CHECKING RWP-3B RUNNING, RWP-3B DISCHARGE PRESSURE GOOD AND DC RAW WATER TEMP NORMAL o INCREASE DC COOLING TO THE DC HEAT EXCHANGER BY INCREASING SETPOINT o Ir RCS TEMPERATURE CONTINUES TO RISE CONSIDER ALTERNATING DECAY HEAT TRAINS PER OP-404.
