o Throughout this procedure "affected" refers to any S/G in which narrow range level is less than 5'/

[25/i adverse CNMT].

o Adverse CNMT values should be used whenever CNMT pressure is greater than 4 psig or CNMT radiation is greater than 10+05 R/hr.

1 Identify Affected S/G(s):

a. Narrow range level

- LESS THAN 5'/i

[25'/o adverse CNMT]

a. Return to procedure and step in effect.

2 Verify S/G Blowdown Isolation Valves From Affected S/G(s)

CLOSED-

~ AOV-5738 for S/G A

~ AOV-5737 for S/G B

Place S/G blowdown valves master switch to CLOSE.

IF valves can

~NO be closed

manually, THEN dispatch AO to locally isolate blowdown.

o S/G A, close V-5701 o

S/G B, close V-5702

3 Check If Affected S/G(s)

Secondary Side Is Intact:

o Pressure in affected S/G(s)

STABLE OR INCREASING o

Pressure in affected S/G(s)

GREATER THAN 110 PSIG IF affected S/G(s) previously identified as faulted.

THEN return to procedure and step in effect.

IF affected S/G pressure decreasing in an uncontrolled manner or completely depressurized and has not been previously isolated, THEN go to E-2, FAULTED STEAM GENERATOR ISOLATION, Step 1.

4 Check AFW Flow To Affected S/G(s)

GREATER THAN 50 GPM IF affected S/G(s) wide range level greater than 35 inches

[100 inches adverse CNMT], THEN establish AFW flow as necessary to refill affected S/G(s).

IF affected S/G(s) wide range level less than 35 inches

[100 inches adverse CNMT].

THEN do not establish AFW flow to affected S/G(s).

Consult the plant engineering staff to evaluate refilling the affected S/G(s) as part of long-term plant recovery and go to 6.
