REDUNDANT INDICATION WHICH WILL VERIFY ALARM:
.o CONTROL BOARD INDICATORS CF-1-PI3 OR CF-1-PI4 OPERATOR ACTIONS FOR' A VALIC ALARM:
o DETERMINE CAUSE AND RETURN CORE FLOOD TANK TO NORMAL PRESSURE o REFER TO OP-401 FOR THIS CONDITION-DISCUSSION:
INCREASING REACTOR BUILDING TEMPERATURES, NITROGEN VALVE LEAKBY FROM N2 BOTTLES, OR INCREASING CFT WATER LEVEL MAY CAUSE CORE FLOOD TANK PRESSURES TO RISE.-
PRESSURE LIMITS ARE ESTABLTSHED PER TS, REFER TO TS FOR ADMINISTRATIVE REQUIREMENTS.
