EOP: AP-RCP.1 TITLE: RCP SEAL MALFUNCTION REV 11 PAGE 4 of 10 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED CAUTION o IF, AT ANY TIME DURING THIS PROCEDURE, A'EACTOR TRIP OR SI OCCURS, E-O, REACTOR TRIP OR SAFETY INJECTION, SHALL BE PERFORMED.

o IF ANY RCP IS TRIPPED, THEN SHUTDOWN MARGIN REQUIREMENTS SHOULD BE VERIFIED (REFER TO 0-3.1, BORON CONCENTRATION FOR XENON FREE ALL RODS IN MOST REACTIVE ROD STUCK OUT SHUTDOWN MARGIN).o IF A RCP IS SECURED BECAUSE OF A SEAL MALFUNCTION, IT SHOULD NOT BE RESTARTED UNTIL THE CAUSE OF THE MALFUNCTION HAS BEEN DETERMINED AND CORRECTED.

NOTE;o If a Reactor trip is iTIitiated while performing Step 1, transition to E-0 should occur while completing subsequent actions of the step.o Total¹1 Seal Flow is defined as the sum of indicated¹1 Seal Leakoff Flow and RCDT leak rate (PPCS Point ID L1003, 3.2 gal/8 in the normal operating range).1 Check Total$1 Seal Leakaff Flows-LESS THAN 8.0 GPM IF a¹1 Seal Failure is verified by a decrease in Labyr Seal Diff Pressure OR increasing Seal Inlet/Outlet temps, THEN perform the following:

a.IF reactor trip breakers closed, THEN trip the reactor.b.Trip the affected RCP(s).c.Allow 4 minutes for pump coast down, THEN close affected RCP(s)seal disch valve.~RCP A, AOV-270A~RCP B, AOV-270B d.IF reactor trip was NOT required, THEN go to Step 4.

EOP: AP-RCP.1 RCP SEAL MALFUNCTION REV 11 PAGE 5 of 10 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED 2 Check RCP Seal Return Valve Alignment:

a.RCP seal return isolation valve, MOV-313-OPEN a.Perform the following:

1)Ensure CI reset.2)Ensure both trains of XY relays for RCP seal return isolation valve, MOV-313, reset.3)Open RCP seal return isolation valve, MOV-313.IF MOV-313 can NOT be opened, THEN dispatch AO to AUX BLDG with RWST area key to check valve and breaker locally (breaker MCC C position 13J).b.Verify RCP seal disch valves OPEN~RCP A, AOV-270A~RCP B, AOV-270B b.Manually open valves.IF valves can NOT be opened, THEN verify IA aligned to CNMT and go to Step 3.

I 0 f EOP: AP-RCP.1 TITLE: RCP SEAL MALFUNCTXON REV 11 PAGE 6 of 10 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED V NOTE: o If a reactor trip is initiated while performing Step 3, transition to E-0 should occur while completing subsequent actions of the step.o The 0.8 GPM limit for¹1 seal flow applies when the RCS is at normal operating pressure.Refer to Figure RCP SEAL LEAKOFF and consult plant staff for guidance if the RCS is at reduced pressure.3 Check Total gl Seal Flow-BETWEEN 0.8 GPM AND 6.0 GPM IF¹1 Seal Inlet and Outlet temperatures are increasing, THEN perform the following:

a.IF reactor trip breakers closed, THEN trip the reactor.b.Trip the affected RCP(s).c.Allow 4 minutes for pump coast down, THEN close affected RCP(s)seal disch valve.~RCP A)AOV-270A~RCP B)AOV-270B IF¹1 Seal Inlet and Outlet temperatures are stable, THEN perform the following while continuing with this procedure.

o IF total¹1 Seal Flow greater than 6.0 gpm, THEN maintain seal injection flow rate of 9.0 GPM or greater to the affected RCP.o IF total¹1 Seal flow exceeds 8.0 GPM OR Seal Inlet/Outlet temperatures begin to increase, THEN return to Step 1.o Prepare for orderly pump shutdown by placing the plant in Hot Shutdown using 0-2.1, NORMAL SHUTDOWN TO HOT SHUTDOWN.o Secure the affected RCP with 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

EOP: AP-RCP.1 RCP SEAL MALFUNCTION REV 11 PAGE 7 of 10 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED NOTE: Attachment RCP DIAGNOSTICS may be used to aid in diagnosis.

4 Check RCP Cooling: o Annunciator A-7, RCP A CCW RETURN HIGH TEMP OR LOW FLOW-EXTINGUISHED o Annunciator A-15, RCP B CCW RETURN HIGH TEMP OR LOW FLOW-EXTINGUISHED Perform the following:

a.Verify RCP CCW supply and return valves open.~RCP A, MOV-749A and MOV-759A~RCP B, MOV-749B and MOV>>759B b.En'sure open CCW outlet valves from RCP thermal barriers.~RCP A, AOV-754A~RCP B, AOV-754B 5 Check RCP g2 Seal Indications:

o Annunciator B-3, RCP A STANDPIPE HI LEVEL+1 FT-EXTINGUISHED' Annunciator B-4, RCP B STANDPIPE HI LEVEL+1 FT-EXTINGUISHED IF affected RCP¹1 seal leakoff flow decreasing, THEN failure of¹2 seal may be indicated.

Continue plant operation while closely monitoring RCP seal indications.

a.Ensure open CCW outlet valves from RCP thermal barriers.~RCP A, AOV-754A~RCP B, AOV-754B b.Verify seal injection flow greater than 5 GPM for affected RCP.c.Adjust HCV-142 as necessary.

d.Dispatch AO to check seal injection filter D/P.e.Check CCW surge tank level stable.IF level increasing, THEN go to AP-CCW.l, LEAKAGE INTO THE COMPONENT COOLING LOOP.7 Check RCP g3 Seal Indications:
