STEP ACTION/EXPECTED RESPONSE

RESPONSE

NOT OBTAINED CAUTION IF, AT ANY TIME DURING THIS PROCEDURE, A REACTOR TRIP OR SI OCCURS, E-O, REACTOR TRIP OR SAFETY INJECTION, SHOULD BE PERFORMED.

NOTE:

Step 1 is an IMMEDIATE ACTION step.

1 Check RCP No.

Indication:

a.

No.

1 seal leakoff flow - LESS THAN 5.5 GPM

a. IF No.

1 seal leakoff flow greater than or equal to 5.5

GPM, THEN close seal disch vlv(s) AOV-270A (A RCP)

OR AOV

-270B (B RCP)

AND perform the following:

o IF Rx at power, THEN:

1) Trip the Rx.

2) Trip the affected RCP(s).

3)

Go to E-O, REACTOR TRIP or SAFETY INJECTION.

o IF Rx shutdown, THEN:

1) Trip the affected RCP(s).

2)

Go to Step 8.

Check No.

1 Seal Indication:

o No.

1 seal leakoff flow-GREATER THAN 0.25 GPM IF No.

1 seal outlet temperature greater than 215'F, THEN go to Step 7.

IF No.

1 seal outlet temperature less than 215'F, THEN verify leakage increase from No.

2 seal to the RCDT.

3 Check No.

2 Seal Indications:

a.

RCP standpipe lo level alarms, B-11/(12) - NOT LIT b.

RCP standpipe hi level alarms, B-3/(4) - NOT LIT

a. IF either RCP standpipe lo level alarm lit, THEN go to Step 4.

b. IF either RCP standpipe hi level alarm lit, THEN go to Step 6.

4 Check Containment Radiation Monitors:

o R NORMAL o

R NORMAL IF RCP standpipe lo level alarm and CNMT radiation increasing, THEN No.

3 seal leakage increase is probable.

Continue plant operation while closely monitoring RCP seal operation.

5 Check Both RCP Diff Press:

o GREATER THAN - 220 PSID IF Rx at power, THEN:

a. Trip the Rx.

b. Trip the affected RCP(s).

c.

Go to E-O, REACTOR TRIP or SAFETY INJECTION IF Rx shutdown, THEN:

a. Trip the affected RCP(s).

b.

Go to Step 8.

Check Both RCP Labyr Seal Diff Press:

o GREATER THAN -

15 INCHES OF VATER IF Labry seal D/P is low, THEN ensure CCW flow to the RCP thermal

barriers, AND

a. Verify charging in service and check seal infection flow.

b. Ad)ust HCV-142 if desired.

c. Direct AO to check seal in]ection filter D/P.

7 Check Both RCP Seal No.

1 Outlet Temperatures:

o LESS THAN - 215'F IF Rx at power, THEN:

a. Trip the Rx.

b. Trip the affected RCP(s).

c.

Go to E-O, REACTOR TRIP or SAFETY INJECTION.

IF Rx shutdown, THEN:

a. Trip the affected RCP(s).

b.

Go to Step 8.
