St ruttural welding SUPPLIED BY:
Reliance Electric Company, Stone Mountain, Georgia NATURE OF DEFICIENCY:
The subject Unit i equipment has been received at the site.
Several welding deficiencies were noted when the equipment was inspected as compared to the vendor drawings.
DATE PROBLEM OCCURRED:
The problem was identified during receipt inspection on March 17, 1983.
DATE PROBLEM REPORTED:
On April 1, 1983, CP&L (Mr. K. V. Hate') notified the NRC (Mr. A. Hardin) that this item was potentially reportable
(
under 10CFR50.55(e).
On April 26, 1983, CP&L (Mr. N. J. Chiangi) notified the NRC (Mr. A. Ibrdin) that this item was reportable under 10CFR50.55(e).
SCOPE OF Ph0BLEM:
The equipment was manufactured in three (3) sections.
It will be bolted together and installed as a single unit.
Deficient welds were identified in each section; eight (8) welds, total.
SAFETY IMPLICATIONS: Seismic qualification of the subject panel is required to assure structural integrity during a seismic event.
Safety-related components are located in the cabinet; thus, structural failure would jeopardize operation of the safety-related equipment.
REASON DEFICIENCY IS REPORTABLE: Welding inspection at the site was done using the vendor's QA manual (QCP 5.3).
Deficient welds did not adhere to the manual.
I
CORRECTIVE ACTION:
CP&L originated a Field Change Request (FCR-AS-2879) to have the welds repaired by site personnel.
The welds have been repaired.
The vendor has been given a copy of the weld deficiency report, the rework done, and has been requested to provide comment and an analysis.
CP&L letter with this information and request is 110-83158 dated May 9, 1983.
PREVENTATIVE ACTION:
The vendor has been instructed to rigorously follow his QA manual for Unit 2 equipment.
FINAL REPORT:
In our July 25, 1983 interim report, we projected the vendor to be complete with their analysis by August 31, 1983 and a final report issued by September 23, 1983.
Since this report, the vendor's external analyst facility has requested additional information for completion of the analysis.
Completion is now scheduled for November 16, 1983.
A final report will be issued af ter CP&L review.
Scheduled report date is December 15, 1983.
