Allegation Category:
QA/QC 7, QA Implementation 2.
Allegation Number:
AQ-20 3.
Characterization:
It is alleged that vendor components with documented defects were released for shipment to the site by QA management.
4.
Assessment of Safety Significance:
The NRC Technical Review Team (TRT) identified the cited components as moment restraints.
By interviewing of Comanche Peak Steam Electric Station (CPSES) personnel and reviewing a Region IV inspection report and moment restraint inspection and nonconfor-mance reports (NCRs) with supporting documentation, the TRT found the fol-lowing.
In June 1980, fabrication of the moment restraints was reportedly completed by Chicago Bridge and Iron (CB&I) and they were ready for ship-ment to CPSES.
Brown and Root (B&R) required a source inspection of the moment restraints to be performed prior to shipment. The inspection, con-ducted on July 22-23, 1980, identified unacceptable conditions which re-quired corrective action before shipment would be approved by B&R. On August 18, 1980, a CB&I response stated that the unsuitable weld surface conditions would not interfere with proper interpretation of nondestruc-tive examinations of the restraints.
CB&I's response took exception to the inspection findings and was not approved by B&R. As cost and schedule constraints came to bear cnd no acceptable corrective action was taken by CB&I, B&R QA management issued a " shipment waiver" to CB&I on September 3, 1980. The waiver released the moment restraints for shipment with known outstanding deficiencies.
This waiver did not waive any rights B&R had under the purchase agreement, including the right to reject the restraints upon discovery of deficiencies during or after their arrival at CPSES.
After thei~r arrival, the moment restraints were inspected. Those moment restraints that were not acceptable were either reworked / repaired on site or returned to CB&I for repair.
These actions were documented on NCR M-2512, dated September 22, 1980, and Texas Utilities Generating Company letter TXX-3544, dated July 19, 1982.
(NCR dispositioning for the moment restraints is also addressed in QA/QC Category 6, allegation AQ-38.)

Conclusion and Staff Positions:
Based on documents reviewed, and interviews performed, the TRT determined that vendor components with documented defects were released for shipment by QA management.
However, the known defects i
were adequately documented prior to shipment.
The moment restraints were inspected after arrival at CPSES.
Noted deficiencies were dispositioned i
as either rework / repair onsite or return to vendor for repair.
These actions tock place prior to the restraints being turned over to craft personnel for installation. Accordingly, there was a controlled method in place for the identification of deficient material at the vendor and fol-lowup at the site to assure that only acceptable hardware was installed.
l l
On October 29, 1984, the TRT was notified that the alleger had declined l
to have any further contact with the NRC.
Accordingly, no closecut interview was conducted.
