Subject: STEAM GENERATOR TUBE EXAMINATION FAILURE

Discussion:

During Con Edison's steam generator tube examination program, defects    
were identified in the No. 23 steam generator roll transition region.    
Con Edison is using a bobbin and CECCO 5 probe with a rotating pancake   
probe to confirm the indications.  The CECCO 5 probe is sensitive to     
axial and circumferential indications.  Preliminary analysis indicates   
that the No. 23 steam generator has 542 pluggable indications on the hot 
leg in the roll transition region of which 20 have some circumferential  
indication.  Because of the quantity of indications, if plugging is      
required, Con Edison may be over the 25% maximum plugging limit.  The    
FSAR describes that the basis for the 25% steam generator tube plugging  
level is the small break LOCA analysis.  The other steam generators have 
similar indications in the roll transition region but not as many.  The  
No. 21 SG has 13 indications and the No. 22 SG has 2 indications.        
Inspection of the No. 24 steam generator is in progress.                 
                                                                         
Con Edison was recently issued a technical specification amendment to    
allow the repair of steam generator tubes via the implementation of an F*
criteria.  The F* distance is the distance of the expanded portion of a  
tube which provides a sufficient length of undegraded tube expansion to  
resist pullout of the tube from the tubesheet.  This would allow tubes   
that are degraded in a location not affecting structural integrity of the
tube to remain in service as an alternative to removal from service      
through the use of tube plugs.  However, Con Edison's attempt to reroll  
several tubes has been unsuccessful because of crud buildup in the       
crevice.                                                                 
                                                                         
Con Edison has also submitted a technical specification change request to
allow sleeving as an alternative to reroll.  The review of this TS change
request is in progress.
