POTENTIAL CAUSES THAT MAY HAVE PREVENTED EARLY DETECTION o SECONDARY ACTIVITY DETECTION METHODS.
o AMOUNT OF DILUTION AT SAMPLING LOCATION.
SAFETY SIGNIFICANCE l EARLY DETECTION OF STEAM GENERATOR (SG) TUBE LEAK IS NECESSARY TO AVOID TUBE RUPTURE.
l DISCUSSION
{
o A SURVEILLANCE TEST OF A CHARGING PUMP ON MARCH 4, l
1993, INCREASED PRIMARY PRESSURE BY 40 PSI. THE FOLLOWING INDICATIONS ALSO OCCURRED: >
SG 2-2 BLOWDOWN ALARM CONDENSER VACUUM EXHAUST RADIATION MONITOR ALARM GRAB SAMPLES ANALYZED FROM HOT LEG BLOWDOWN SAMPLE FOR Iun DID NOT SHOW ANY SIGNIFICANT DIFFERENCE IN SG LEAKAGE.

PALO VERDE, UNIT 2 93-27 o SG LEAKAGE ASSESSMENT COMPARISON USING TWO METHODS YIELDED VERY DIFFERENT RESULTS. THIS ASSESSMENT WAS DONE DURING AN NRC INSPECTION IN JULY 1993 USING SAMPLES DRAWN SHORTLY AFTER THE MARCH 4, 1993, TRANSIENT.
o LICENSEE HAD RELIED ON I un ANALYSIS FROM HOT LEG BLOWDOWN SAMPLE THAT SHOWED 9.3 TO 9.8 GPD SG LEAKAGE.
o XE i33 ANALYSIS OF CONDENSER VACUUM EXHAUST SAMPLES DONE IN JULY SHOWED 87 TO 105 GPD SG LEAKAGE SHORTLY AFTER THE TRANSIENT.
o CE LETTER ON BULK WATER CHEMISTRY DATED DECEMBER 10, 1992, INFORMED THE LICENSEE THAT THE HOT LEG BLOWDOWN SAMPLE WAS DILUTED BY A FACTOR OF 5 TO 10 FROM FEEDWATER SPILLING OVER THE DIVIDER PLATE IN SG.
SUGGESTED THE USE OF UNIQUE SAMPLE POINT AT THE DOWNCOMER LOCATION.
o LICENSEE REMAINED WITH THE HOT LEG BLOWDOWN FOR I SECONDARY ACTIVITY MONITORING EXCEPT FOR COLD CHEMISTRY SAMPLES.
LICENSEE ACTIONS o SHUT DOWN THE PLANT FOR 50 GPD LEAK.
o SHUT DOWN THE PLANT FOR 50% INCREASE IN LEAK IN ANY 24 HR. PERIOD.
