EOP: TITLE:

REV' AP-CCW.2 LOSS OF CCW DURING POWER OPERATION PAGE 2 of 8 A. PURPOSE This procedure provides the steps necessary to respond to a loss of CCW while the plant is at power.

B. ENTRY CONDITIONS/SYMPTOMS

1. SYMPTOMS The symptoms of LOSS OF CCW DURING POWER OPERATION are; a Annunciator A-13 COMP COOLING SURGE TANK LO LEVEL 41.24,

                                                                    • CAUTION IF CCW FLOW TO A RCP IS INTERRUPTED FOR GREATER THAN 2 MINUTES OR IF EITHER RCP MOTOR BEARING TEMPERATURE EXCEEDS 200'F, THEN CCW SHOULD BE CONSIDERED LOST TO THAT RCP, REFER TO STEP 3.

1 Check CCW Pump Status: Perform the following:

o Annunciator A-17, Motor Off RCP a. Verify auto start of standby CCW CCP - EXTINGUISHED pump or start manually.

o Both CCW pump breaker white b. IF Annunciator A-22, CCW pump disagreement lights discharge lo press 60 psi LIT, EXTINGUISHED THEN check closed CCW to RHR HXs (MOV-738A and MOV-738B).

EOP: TITLE REV: 9 AP-CCW.2 LOSS OF CCW DURING POWER OPERATION PAGE 4 of 8 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED NOTE: CCW surge tank level should be verified locally in the Aux Bldg, if possible.

2 Verify CCW Surge Tank Level Normal:

a. CCW surge tank level a. Open RMW to CCW surge tank APPROXIMATELY 50% AND STABLE (MOV-823) and start a RMW pump and perform the following:

IF surge tank level is stable or increasing, THEN go to Step 3.

IF surge tank level can NOT be maintained greater than 10%,

THEN 0

1) Trip the Rx.
2) Trip the RCPs.
3) Place both CCW pumps in pull stop.
4) Go to E-O, REACTOR TRIP or SAFETY INJECTION.

~e EOP: TITLE:

REV: 9 AP-CCW.2 LOSS OF CCW DURING POWER OPERATION PAGE 5 of 8 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED CAUTION IF AN RCP(S) IS TRIPPED DUE TO A LOSS OF CCW, SEAL INJECTION SHOULD BE MAINTAINED TO THE IDLE RCP(S) UNTIL RCS TEMPERATURE IS LESS THAN 200'F, OR UNTIL CCW IS RESTORED.

3 Check CCW To Both RCPs: IF CCW lost to RCP(s), THEN:

o Annunciator A-7 (A-15), RCP 1A a. Trip the Rx.

(1B) CCW return Hi temp or low flow 165 gpm 125'F alarm- b. Trip affected RCP(s).

EXTINGUISHED

c. Go to E-O, REACTOR TRIP or o RCP motor bearings temperature SAFETY INJECTION.

EOP:

REV: 9 AP-CCW.2 LOSS OF CCW DURING POWER OPERATION PAGE 6 of 8 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED NOTE: o An evaluation must be made to determine if operation may continue while investigating a CCW leak in containment.

o Operation may continue with the reactor support coolers isolated.

If this occurs, notify higher supervision.

5 Check For CCW Leakage In CNMT:

a. CNMT sump A levels - NOT a. IF abnormal increase in CNMT INCREASING NOTICEABLY sump level, THEN:

l) Direct HP Tech to sample sump A for chromates.

2) Prepare to make CNMT entry to check for CCW leak.
b. RCP oil levels - NOT INCREASING b. IF any RCP oil level increasing uncontrollably, THEN:
1) Close CCW to and from affected RCP(s), (MOVs 749A and 759A for "A" RCP; MOVs 749B and 759B for "B" RCP).
2) Trip Rx.
3) Trip affected RCP(s).
4) Go to E-O, REACTOR TRIP or SAFETY INJECTION.
