o CHECK NITROGEN SUPPLY ISOLATION VALVE CLOSED.
o IF PRESSURE ALARM CAUSED BY HIGH LEVEL, RESTORE LEVEL TO NORMAL BAND.
DISCUSSION:
THIS ALARM COULD BE CAUSED BY RISING TANK LEVEL DUE TO IN LEAKAGE FROM A LETDOWN COOLER OR RCP SEAL PACKAGE COOLER, OR A RISE IN SW SYSTEM TEMPERATURE DUE TO A LOCA OR COMPONENT FAILURE.
IF NECESSARY TO REDUCE TANK PRESSURE A MANUAL VENT VALVE (SW-198) IS AVAILABLE TO VENT THE EXCESS PRESSURE TO THE AB VENTILATION SYSTEM.
