V.C. Summer Nuclear Station Unit #1 License CPRP-94, Response to NRC Audit Report 50-
-20_
dated 9/4/80 a __0-395/80-21((>
dated 9/11/80 Gentlemen:
a In response to NRC reports 50-395/80-21 and 50-395/80-20, we have reviewed the information therein contained and find no proprietary information. In addition, we have evaluated the circumstances relating to the item of non-i compliance No. 80-20-01 and provide the following results of that evaluation.
80-20-01 Dealt with failure to follow procedure for fit-up of butt welded pipe.
1.
Cause The time frame in which the fit-up of the butt joint identifled in this item of noncompliance was made, was June-July 1979.
It was at that time that the craf t and constructor's ASME Code QC failed to follow procedures and accepted a fit-up that did not meet criteria. SCE&G believes that this occurrence is further manifestation of the constructor's ASME in-spection program breakdown that was reported in various communications to Region II associated with items 79-35-02, 79-24-02, 80-05-06 and 79-36-04.
The breakdown resulted from any of a combination of factors including some specific procedural inadequacies, and some less specific interpre-tation, training, competency, attitude, and supervision inadequacies.
2.
Immediate Corrective Steps Taken Upon discovery, during this NRC visit, that a potential mismatch and/or 4
underwall condition existed for the specific weld joint in question, i
SCE6G took specific steps to ascertain the adequacy.of the joint. The data associated with this joint was added to that taken and being analized for a generic concern on mismatch and fit-up presently assigned NRC unresolved Item 79-35-05.
SCE&G Engineering and their agents are t'

October 3, 1980 presently determining what the significance is of some mismatch and underwall conditions in Class 3 Butt Welds.
The conclusions of the actions taken with respect to 79-35-05 will apply to the wold joint in question, as well as all other Class 3 Butt Welds with question-

able' fit-up of which SCE&G has cognizance. No specific items of action were determined eppropriate with respect to the failure to follow procedure based on 3. to follow.
L 3.
Corrective Steps to Avoid Future Noncompliance l
j Commensurate with many corrective actions taken in December 1979 and January 1980, with respect to the constructor's ASME code inspection f
program breakdown, certain actions were taken with respect to Class 3 Eutt Welds. A work hold was placed on code QC work at that time while 4
procedures were amplified and clarified, and QC organizations were reorganized, and extensive indoctrination and training took place.
The work hold on Class 3 Butt Welds was released January 2,1980 at j
which time it was determined Class 3 Butt Welds could be made within i
procedural guidelines by properly trained personnel.
SCE6G believes the corrective actions implemented in December 1979 and January 1980, with respect to the many concerns in existence as a result of the 4
constructor's QC breakdown, have eliminated the potential for recur-rence of the procedure violation that occurred in June-July 1979.
4 We trust that you will find _ the SCE6G actions to resolve this item both j
appropriate and satisfactory. Please feel free to contact us if further clarification or information relative to this itcm is needed.
Very truly yours, T. C. Nichols, Jr.
