RECENT TRENDS OF CONCERN e SCC IS DOMINANT DEGRADATION MECHANISM AFFECTING SGS
- 40% THROUGH WALL CRACKS CANNOT BE RELIABLY DETECTED
- CRACKS CAN BE RELIABLY DETECTED BEFORE TUBE INTEGRITY IS IMPAIRED, BUT ONLY IF THE LICENSEE USES THE ,
APPROPRIATE TEST EQUIPMENT (INCLUDING PROBES), TEST
~ PROCEDURES, AND DATA ANALYSIS PROCEDURES AND IF THE '
ANALYSTS HAVE BEEN ADEQUATELY TRAINED AND TESTED ON THESE PROCEDURES
- THERE HAVE BEEN WIDESPREAD DEFICIENCIES IN INSPECTION PROGRAMS THROUGHOUT THE INDUSTRY (SEE INFORMATION NOTICES 92-80, ETC.)
- APPARENT CRACK GROWTH RATES CAN BE HIGH; MID-CYCLE INSPECTIONS ARE SOMETIMES NECESSARY (E.G., MCGUIRE 1 AND 2, ANO-2) e SCC IN FREESPAN IS BECOMING MORE PREVALENT E.G., MCGUIRE 1 AND 2, PALO VERDE 2, FARLEY l
- CAUSED THE TWO MOST RECENT RUPTURES (MCGUIRE 1, PALO VERDE 2)
- EXTRAORDINARY MEASURES TO ENSURE A QUALITY INSPECTION HAVE BEEN NECESSARY TO PROVIDE ASSURANCE OF. TUBE INTEGRITY AT MCGUIRE AND PALO VERDE l

- SUMMER HAD REQUESTED A 1 VOLT IPC FOR THE JUST COMPLETED SPRING 1993 REFUELING OUTAGE, BUT WITHDREW THE REQUEST e SEVERAL INDICATIONS RANGING FROM 7 TO 22 VOLTS WERE FOUND DURING THE SPRING 1993 INSPECTION AT THE FLOW DISTRIBUTION BAFFLE PLATES
