A. BACKGROUND NRC INFORMATION NOTICE NO. 91-056 ALERTS LICENSEES TO POTENTIAL PROBLEMS RESULTING FROM THE LEAKAGE OF ISOLATION VALVES IN THE ECCS RECIRCULATION LINES TO THE RWST, WHICH IS VENTED TO ATMOSPHERE. THE SAFETY INJECTION AND CONTAINMENT SPRAY SYSTEMS AT STP HAVE PEEN EVALUATED FOR THE POTENTIAL LEl\K PATH AS DESCRIBED IN THE INFORMATION NOTICE. IT HAS BEEN CONCLUDED THAT THE CONDITION DESCRIBED BY THE IN APPLIES TO BOTH STP UN.TTS.

THE POTENTIAL EXISTS FOR BACKLEAKAGE OF CONTAMINATED SUMP WATER l

INTO THE RWST DURING THE RECIRCULATION PHASE OF SAFETY INJECTION FOLLOWING A LOCA. THE POTENTIAL LEAKAGE IS FROM THE SI PUMP RECIRCULATION LINE ISOLATION VALVES, THE CONTAINMENT SPRAY SYSTEM TEST LINE ISOLATION VALVES AND THE RWST SUCTION LINE ISOLATION VALVES. IF BACKLEAKAGE OCCURS, THE RWST MAY BECOME A SOURCE OF AIRBORNE RADIOACTIVITY.

1 THE DESIGN FUNCTION OF THE RWST SUCTION AND SI/CS ISOLATION VALVES (21 TOTAL VALVES) IS TO PREVENT RADIOACTIVE WATER FROM I l

CONTAMINATING THE RWST DURING RECIRCULATION PHASE (REF. 10).

(NOTE: AS A RESULT OF ITS DESIGN FUNCTION IN THIS SYSTEM, CHECK

CALCULATION.] THE IMPACT OF A DEGRADED LEAK RATE THROUGH THESE VALVES SHALL BE DETERMINED.

B. OBJECTIVE THE OBJECTIVE OF THIS CALCULATION'IS TO DETERMIME THE IMPACT OF A SUBSTANTIALLY DEGRADED LEAKAGE CONDITION FOR THE ECCS ISOLATION VALVES, THUS ALLOWING A GREATER THAN DESIGN LEAKAGE TO MIGRATE BACK TO THE RWST. THE RWST SUCTION LINE ISOLATION VALVES (SI-

{ THE CONTAINMENT SPRAY PUMP'S TEST LINE ISOLATION VALVE (CS-0008).,

FOR THE THREE.(3) SAFETY TRAINS (A, B &C), ARE CONSIDERED IN THIS j ANALYSIS.

THE RESULTS OF THIS CALCULATION WILL PROVIDE THE BASIS FOR ASSUMED INLEAKAGE TO THE RWST (ELAPSED TIME AND INFLUENT RATE),

l l l AND CONSEQUENTLY WILL BE USED TO DETERMINE THE EXTENT OF THE 1

VI. METilOD 0F ANALYSIS  !

Tile METilOD OF ANALYSIS FOR THIS CALCULATION IS TO ASSUME Ti!E DESIGN BASIS MAXIMUM PERMISSIBLE MAIN SEAT LEAKAGE RATE FOR EACll ECCS ISOLATION VALVE, AS SPECIFIED BY Ti!E PURC11ASE SPECIFICATIONS, TO DETERMINE Tile RATE OF SUMP WATER BACKLEAKAGE INTO TiiE RWST. A GREATER LEAK RATE WILL BE ASSUMED TO DETERMINE Ti!E TRANSPORT TIME FOR T!!E LEAKAGE FROM Tile VALVE TO Tile RWST.

Ti!IS IS Tile TIME REQUIRED FOR INLEAKAGE VOLUME TO DIF? LACE THE EXISTING WATER VOLUME.

SINCE Tl!E DRIVING FORCE (llEAD) FOR LEAKAGE TilROUGli Tile RWST SUCTION LINE ISOLATION VALVES (SI-0001 AND 2) IS THE POST ACCIDENT PRESSURE IN TiiE CONTAINMENT (REF. 1. ALSO SEE ATTACHMENT 1.), TilIS LEAK PATH AND PRESSURE / TIME RELATION WILL DE EVALUATED, FOR Tile TilREE (3) SAFETY TRAINS (A, B & C).
