ICE CONDENSER BASKETS FOUND IN UNANALYZED CONDITION              

                                                                 

THE LICENSEE DISCOVERED, DURING AN INSPECTION OF UNIT ONE ICE    

CONDENSER, MISSING AND OR DEFECTIVE WELDS ON THE BOTTOM CROSSBAR 

AND BOTTOM BASKET GRIDS OF THE ICE CONDENSER BASKETS.  THE       

LICENSEE EXPECTS TO FIND SIMILAR CONDITIONS IN THE UNIT TWO ICE  

CONDENSER.  THIS CONDITION IS UNANALYZED AND AN INVESTIGATION    

WILL CONTINUE INTO THE CAUSE OF THESE CONDITIONS.  THE CONDITION 

IS BEING REVIEWED FOR REPORTABILITY UNDER 10CFR PART 21.         

                                                                 

THE DEFECTIVE ICE BASKET BOTTOM RIMS WILL BE REPAIRED OR REPLACED

AS APPROPRIATE BEFORE ENTERING PLANT STARTUP.                    

                                                                 

THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR.                

                                                                 

*** UPDATE ON 7/10/98 @ 1704 BY KELLY TO GOULD ***               

                                                                 

THE LICENSEE IS CONSIDERING THIS CONDITION TO BE A PART 21 REPORT

SINCE THEY DETERMINED THE REPORTED ICE CONDENSER DAMAGE IS MORE  

OF A MANUFACTURING DEFECT THAN DAMAGE.  IT IS EXPECTED THAT      

SIMILAR CONDITIONS WILL BE FOUND ON UNIT 2.                      

                                                                 

THE RESIDENT INSPECTOR WAS INFORMED.
