Licensee Action on Previous Inspection Findings Not inspecte.
Unresolved Items Unresolved items were not identified during this inspectio.
Independent Inspection Effo_rt The inspector conducted a general inspection of the auxiliary building, the containment and radiographic laboratory to observe construction
-2-progress and construction activities such as welding, post weld heat-treatment, NDE inspection, radiation control, material handling and control, housekeeping and storag The inspector examined the below listed welds while post-weld heat treatment was in progress to determine compliance with applicable regulatory requirements and licensee approved program and procedures.,
Weld N Drawing N RYS 40007-RZ-U2B ETA 40007-EZ-UZB System Main Steam Main Steam In the areas inspected no items of noncompliance or deviations were identifie.
Steam Generator Replacement Observation of Welding and Associated Activities The inspector observed field repair welding of reactor coolant pressure boundry piping at various stages of weld completio The applicable code as required by VEPCO's licensee submittal (Steam Generator Project Surry Power Station Unit Nos. 1 and 2, Revision 9), is ASME Section XI, 1974 Edition with Addenda through the Winter of 197 Based on paragraph IWA-7000 of Section XI, VEPCO is using the original construction code (USAS B31. ) for pipe weldin Welding qualifications and procedure qualifications are being performed in accordance with the latest edition and addenda of ASME Section IX in effect at the time of the qualification. All welding materials were purchased and certified in accordance with Class I require-ments of the ASME cod Nondestructive testing is being performed in accordance with ASME code,Section III and V, 1974 Edition with Addenda through the Winter of 197 The inspector made the following examinations of the repairs to weld N ¥2A of ETA 40004D-1 The inspector examined repair excavations, prior to welding, to deter-mine-whether weld identification/location, and preparation, evidence of QC verification meet applicable procedure The inspector examined weld repairs where the root pass (only) has been completed to determine; weld/welder identification, qualified welder/weld procedure, physical appearance of weld and evidence of QC verificatio The inspector examined weld repairs where welding was beyond the root pass to determine; weld/welder identification, qualified welder/weld procedure, periodic checks of welding variables, use of specified weld material, proper interpass temperature and where applicable pre-heat and post-weld heat treatment and physical appearance of weld ( starts, stops, undercut and surface imperfections).
-3-The inspector observed activities at weld material issue station to determine adequacy of; weld material storage/segregation, oven tem-peratures, issue records and return of unused weld materia Also observed work areas for uncontrolled weld materia Within the areas examined, there were no items of noncompliance or deviations identifie r Steam Generator Replacement - Non-Destructive Examination The applicable codes are specified in Paragraph 6 abov Review of Procedure The inspector reviewed the below listed procedures to determine whether the procedures were consistent with regulatory requirements and licensee commitment (1)

,,
The inspector reviewed one hundred thirty-nine liquid penetrant exami-nation reports, forty-five ultrasonic examination reports, twenty-eight magnetic particul inspection reports, twelve radiographic examination
.reports and the applicable procedures to determine whether the selected records contained or provided reference to the following documents:
(1)
Examination results and data sheets (2)
Examination equipment data (3)
Calibration data sheets (4)
Records on program deviations, if any (5)
Identification of N.D.E. Material such as penetrant, cleaner, couplant, films, tape, et (6)
(7)
The recording, evaluation and disposition of findings are in compliance with the applicable N.D.E. procedures and code requirement Evaluation of data complies with the criteria of the N. procedure.
