Licensee Action on Previous Inspection Findings Not inspecte. Unresolved Items Unresolved items were not identified during this inspectio. Cracking in Feedwater System Piping As part of followup inspection to IE Bulletin 79-13, the inspector reviewed the licensee's weld records relative to replacement of steam generator feedwater line reducers. The applicable codes for the replacement work were:
ASME Section XI, 1974 Edition, with Addenda through the summer of 1975; ANSI B31.1, 1977 Edition with Addenda through the summer of 1978; ASME Section IX, latest Edition and Addenda; ASME Section V, 1977 Edition with Addenda through the winter of 1978; and ASME Section II;NC 5000, 1977 Edition with Addenda through the winter of 1978 (RT Acceptance).
The following records were reviewed for welds 16-FW-9-25-W2, 16TFW-9125-FW12, 16dFW1151-FW33, 16oFW-10-37-FW 21, 16-FW-10-37-W2, and 16-FW-11-51-W a. Welding procedure qualification records consisting of:
(1) Instruction 1444-K-WO01, Rev. C, "Welding For Carolina Power and Light Robinson" (2) WPS 1:3.1.5-001, Rev. 0 (3) WPS 1.1.5-007, Rev. 0 (4) PQR 0078 Weld history records consisting of:
(1) Weld Fit-up Chit (2) Weld Root NDE Chit (3) Weld Final NDE Chit The welds were made with a consummable insert root pass followed with W
the gas tungsten arc (GTA) process using bare wire to obtain a thick ness of approximately 3/8-inch, and then filled with the shielded metal arc (SMA) process. Section 10, paragraph 10.3150 of the Newport News Industrial Corporation (NnI) "ASME Nuclear Quality Assurance Manual" requires that filler material description and identification be recorded on the applicable chits.During review of the records available at the site the inspector found that the bare wire used over the root was not recorded on any chit. At the time of the inspection, the responsible NNI personnel could not be located for an explanation for the missing records. On July 20, 1979, site personnel contacted'
the inspector by phone and stated that during compilation of weld records for the site, NNI had inadvertantly left out the chits showing the bare wire, mistakenly considering the chits to be duplicates of the root pass chit These chits will be reviewed on a future inspec tion. This item is identified as inspector followup item 261/79-16-0 c. Welder qualification records NNI "Certificate of Qualification" for QC inspectors Law Engineering "Certificate of Personnel Qualification" for 5 NDE inspectors f.
