, Steam Generator Feedwater Ring J-Nozzles Modification - Units 1 and 2 (1) During this inspection, the inspector reviewed procedures, j

~

verified examinations, and reviewed records associated with the steam generator modification being accomplished by Westinghouse U Electric Corporation g) on the Unit 1 and 2 steam generator .The modification is .being accomplished as authorized by W Field Change Notice (FCN) GAEM1060 The FCN authorizes replacement of existing carbon steel J-nozzles i in the feedwater- distribution ring with Inconel J-nozzles for

, improved erosion-corrosion resistance. J-nozzle material conforms i

to ASME SB-167 NiCrFe alloy 600 seamless pip ~

There are 30 J-nozzles in each of the steam generators. The field modification

, is being accomplished per detailed installation' instructions i provided in Procedure SSS-2.7.2-GEN 33 Rev. 3, J-Nozzle Replace-men The feedwater distribution ring J nozzle assembly is classified Safety Class I The feedwater ring assembly is not part of the pressure vessel boundar (2) The inspector reviewed the below listed W procedures for technical

position on valve number BT738 adjacent to the weld. Final visual-examination of the weld had been conducted by PPP and

the arc strike and weld spatter appeared to. have occurred j

after the final acceptance of the weld. The inspector noted that this appeared to be an isolated incident as none of the '

other welds examined had indications. The inspector informed PPP of the condition and deviation report No. PP-11924 was issuad by PPP to disposition the indications. The inspector has no further questions regarding ~ this matter since the condition appears to have occurred.after final acceptance of

the weid, t.1d was an isolated case, and disposition of the condition was being addressed.
