4. NATURE OF OEFICIENCYr THE VALVE BONNET FLANGE WELDMENT SHOULD HAVE BEEN LIQUID PENETRANT EXAMINED ON TWO SIDES IN ACCORDANCE WITH THE ASME PRESSUFC VESSEL CODE. BECAUSE OF AN INCOMPLETE WELD SYMBOL ON THE FABRICATION DRAWING THE WELO WAS LIQUID PENETRANT EXAMINED ON ONE SIDE: 0NLY.

THUS A POSSIBILITY EXISTS THAT A SURFACE INDICATION. MAY BE PRESENT THAT COULD RESULT IN A REDUCTION OF THE INTEGRITY OF THE REAGTOR COOLANT PRESSURE DOUNDARY. IT IS. FELT.THAT THE PROBADILITY IS GUITE LOW, -

IN THAT EXAMINATION.0F 6 IDENTICAL WELDS (12 SIDES) OF PARTS CURRENTLY IN FABRICATION HAS REVEALED ONLY ONE SIDE OF ONE VELD WITH MINOR INDICATIONS. THESE INDICATIONS HAVE BEEN REMOVED AND NO WELD REPAIR WAS REGUIRED.  ;
