SD 413, 414/81-07 Report Date June 5, 1981 Facility:
Catawba Nuclear Station I & 2 Identification of Deficiency Dce to lack of proper understanding or training, certain Nonconforming item Reports appear to have been resolved without adequate consideration of reportability under Part 21 or 50.55e.
f r.i tial Report On May 8, 1981, Mr. J. Bryant of NRC Region ll, Atlanta, Ga. was notified
(
of this deficiency by Messers W. O. Henry, D. M. Collings and R. L. Williams I
of Duke Power Co., Charlotte, NC 28242. This notification was as a result of Potentially Reportable i tem CA-81-10 (sheets 1 and 2).
Supplier and/or Component This report covers various piping materials from many different suppliers and manufacturers.
Description of Deficiency l
The materials in question were nonconformed at various points in time such as receipt inspection, during installation and after installation. The Nonconforming item Reports were resolved by CoM truction and the resolutions were to scrap, repair or downgrade the material.
These should have been j
forwarded to Design Engineering f or eve,luation and consideration of reportability.
Analysis of Safety implications if the deficiency were not corrected, Reportable items might have gone undetected.
The resolutions as originally made were conse vative to the extent that the ques tionable materials did not go undetected and were not used in Safety Related Systems. These materials are no longer available l
for further evaluation. We have reviewed the Nonconforming I tem Reports
)
in question.
Our review of these did not disclose any trend to indicate a problem generic to any manufacturer or material with one exception. This I
exception relates to the problem of centerline lack of fusion on SA-312 double welded pipe. We have previously addressed this problem and are within the guidelines established by NRC IE Bulletin 79-03A.

Pzge 2 Corrective Action As a result of this finding, our QA Procedures on. the handling of NCis and Reportability have been revised. The people responsible for handling Noncon-forming item Reports in Construction, quality Assurance and Design Engineering have received training on the revised procedures. All Nonconforming item Reports pertaining to material problems are now being sent to Design Engineering for evaluation and resolution.
