Reference:
50-424, 84-26, 50-425/84-26 Attention: Mr. H. C. Dance The Georgia Power Company wishes to submit the following information concerning the violations discussed in your inspection report 50-424/84-26 and 50-425/84-26:
Violation 50-424, 425/84-26-01,
" Failure to Address All Essential Variables in WPS" - Severity Level V.
The violation identified a Chicago Bridge and Iron Company (CBI) welding procedure specification, WPS-Stud Welding /74-2195/6, which failed to address or describe the flux type, an essential variable for stud welding, as required in Section IX, Table QW-261 and paragraph QW-402.9, of the ASME Boiler and Pressure Vessel Code.
Georgia Power Company offers the following response pursuant to the criteria of 10 CFR 2.201:
(1) Georgia Power Company acknowledges the violation as identified in the NRC inspection report.
(2) To determine the reasons for the violation, Georgia Power Company contacted the responsible CBI welding engineer.
The welding engineer indicated that it was CBI's practics to address all essential variables in welding procedure specifications and attributed the discrepancy in WPS-Stud Welding /74-2195/6 to human error.
Following a
review of other CBI welding procedure specifications used on the Vogtle Project, the welding engineer confirmed that essential variables were addressed as required in all but the one in question; therefore, Georgia Power Company considers the discrepancy identified in the violation to be an isolated case.

-(3) CBI is presently _ revising WPS-Stud Welding /74-2195/6 to properly address the use of aluminum deoxidizer-flux tips as an essential variable.
(4) Since the-- discrepancy identified in the violation has. been determined to be an isolated case of human error, no-action to prevent recurrence is necessary.
(5) The new revision of WPS-Stud Welding /74-2195/6 is expected to be completed by December 21, 1984.
Full compliance with applicable regulatory requirements will be achieved at that time.
This response contains no proprietary information and may be placed in the NRC Public Document Room.
Yours truly
