Intact:
IF affected S/G(s) previously identified as faulted. THEN return to procedure and step in effect.
o Pressure in affected S/G(s)
STABLE OR INCREASING IF affected S/G pressure decreasing in an uncontrolled manner or o Pressure in affected S/G(s) completely depressurized and has GREATER THAN 110 PSIG not been previously isolated, THEN go to E-2, FAULTED STEAM GENERATOR ISOLATION, Step 1.
4 Check AFW Flow To Affected IF affected S/G(s) wide range level S/G(s) GREATER THAN 50 GPM greater than 35 inches [100 inches adverse CNMT], THEN establish AFW flow as necessary to refill affected S/G(s).
