Failure to Perform a Required 4-Way Ultrasonic Examination of Pipe 1.
Introduction Southwest Fabricating and Welding Company, Inc., (SFW) was informed in July 1980, by South Carolina Electric and Gas Company personnel of a SFW failure to perform all required ultrasonic examinations oa a 20 feet piece of SA 376 Type 3041 inch schedule 160 pipe, which had been furnished to the V. C. Summer Unit 1 site in November 1977.
The sacerial, which had been shipped loose (i. e. not part of a fabricated assembly), had been ultrasonically examined in accordance with applicable ASME Section III Code for the contract, 1971 Edition through Summer 1973 Addendum, but not also in accordance with the contractually applicable supplementary requirements contained in Regulatory Guide 1.66.
2.
Inspection Objectives The objectives of this inspection were to review the nature and scope of the reported deficiency and determine any generic implications.
3.
Method of Accomplishment The preceding objectives were accomplished by:
Review of QA Program requirements in Section 2.0 (Drawing and a.
Specification Control), Section 3.0 (Procurement), Section 4.0 (Receiving Inspection) and Section 5.0 (Process Control) of Revision 0 of the July 1, 1980, edition of the QA Manual.

3 b.
Examination of Gilbert Specification SP-545-04461-000 with respect to material nondestructive examination requirements.
c.
Discussion with SFW management relative to background informa-tion on the criteria used to evaluate the nature and scope of the reported deficiency and examination of the results.
d.
Review of nondestructive examinations performed on materials in 14 ASME Section III Class 1 piping assemblies for the South Texas project, with respect to applicable Code and contract requirements.
Review of nondestructive examinations performed on materials in e.
six (6) ASME Section III Class 3 piping assemblies for Shearon Harris Unit 1, with respect to applicable code and contract requirements.
4.
Findings a.
Deviation from Commitment SFW review of V. C. Summer Unit 1 ASME Section III Class 1 piping systems with a design pressure greater than 275 psig, identified a total of nine (9) piping assemblies where all pipe materials had not received ultrasonic examination in the additional directions required by Regulatory Guide 1.66.
Each of these discrepancies and the one (1) identified by South Carolina Electric and Gas Company are attributable to the fail-ure of SFW QA staff to assure the release of materials into fabrication, which had been ultrasonically examined in accordance with the requirements specified by SFW Engineering on the applic-able assembly detail sheets.
The nine (9) discrepant piping assemblies were furnished for the Safety Injection System and are identified by the following Piece Mark Nos:
1-51-24-12, 1-SI-19-01, '.-$1-21-01, 1-SI-21-03, 1-51-22-01, 1-SI-22-03, 1-51-23-01, 1-SI-23-03, and 1-SI-23-04.
Review of ultrasonic examination reports for the discrepant items showed examinations had been performed in accordance with either an internal SFW procedure or ASTM E213.
As such, the discrepancies would indicate a failure to provide for the review of material certification by personnel with cognirance of the applicability of specific ultrasonic nondestructive examination procedures.
(See Notice of Deviation).
4 b.
Generic Implications Inspector review of two (2) other piping contracts showed no other instance of QA staff approving use of materials, which had not been ultrasonically examined in accordance with applic-able code and contract requirements.
It would therefore appear from the information available, that the problem is not generic in scope but rather related to failure to provide for adequate implementation of a specific contract unique requirement.
C.
Exit Meeting The inspector met with the management representatives denoted in paragraph A. above on September 3,1980, at the conclusion of the inspection.
The inspector informed management that the special inspection was performed as a result of information provided to Region IV by Region II of the Office of Inspection and Enforcement, relative to an identified failure to perform all required ultrasonic examinations of piping sacerial furnisl*d to the V. C. Summer Unit I site.
The inspector summarized the scope ano findings of the inspection and requested review of QA Program adequacy with respect to scope and criteria used for review of materials certification. Manage-ment acknowledged the statements of the inspector and had no specific questions relative to the findings as presented to them.
