Dear Mr. O'Reilly:
Attached is our second interim report on the subject item which was deemed reportable per the provisions of 10CFR50.55(e), on April 28, 1983. CP&L is pursuing this matter, and it is currently projected that. corrective actior. and submission of the final report will be accomplished by September 2, 1983. Thank you for your consideration in this matter. Yours very truly, pyf R. M. Parsons Project General Manager Shearon Harris Nuclear Power Plant RMP/sh Attachment cc: Messrs. G. Maxwell /R.

I S UBJECT: Shearon Harris Nuclear Power Plant, Unit 1,10CFR50.55(e) i reportable deficiency in auxiliary relay cabinets supplied under Purchase Order NY-435246. ITEM: Structural Welding SUPPLIED BY: Systems Control Corporation, Iron Mountain, Michigan NATURE OF DEFICIENCY: The subject Unit 1 equipment has been received at the site. Weld deficiencies were noted when compared to the vendor's welding criteria. DATE PROBLEM OCCURRED: The problem was identified during a CP&L, vendor, and Ebasco meeting / inspection at the site on October 21, 1982. l DATE PROBLEM REPORTED: On November 1,1982, CP&L (N. J. Chiangi) notified the NRC (A. Hardin) that this item was potentially reportable under 10CFR50.55(e) but not 10CFR Part 21. On November 30, 1982, CP&L (R. M. Parsons) notified the NRC (J. P. O'Reilly) that this item was, af ter further evaluation, potentially reportable under 10CFR21 also. More recent evalution has determined that since CP&L QA did not accept the equipment through our QA program, it is potentially reportable only under 10CFR50.55(e). On April 28, 1983 CP&L (N. J. Chiangi) notified the NRC (A. Hardin) that this item is reportable. SCOPE OF PROBLEM: The deficiency involves the following relay cabinets supplied under this purchase order: 1 1A-SA, IB-SB, 2A-SA, 2B-SB, 3A-SA, 3B-SB, 4A-SA, 4B-SB, 19A-SA, 19B-SB. SAFETY IMPLICATIONS: Seismic qualification of the cabinets is required to assure structural integrity during a seismic event. Safety-related components are located in the cabinets; thus, structural failure would jeopardize operation of safety-related equipment. REASONS DEFICIENCY IS REPORTABLE: The cabinets were inspected on site. HPES evaluated these defects and identified 16 as being potentially significant to the structural integrity of the equipment i pertaining to seismic qualification. 4 y- .-m ..--,,-,e- .,-.---,--e ww.-m-,
CORRECTIVE ACTION: 1. The vendor has supplied revised drawings with critical welds identified. 2. The vendor has done a seismic analysis (shake test) to determine structural integrity of Cabinets 1&4A-SA and 1&4B-SB as-built. The report of this analysis has been received and reviewed. Based on this report and testing and HPES evaluation of apparent weld deficiencies, the cabinets are judged acceptable and seismically qualified. 3. HPES has issued FCR-AS-2919 to correct apparent deficiencies identified by RPES. The welds have been corrected. 4. HPES has requested the vendor to evaluate the deficiencies as identified by the DDR and the HPES analysis. The HPES letter to the vendor is HO-83165 dated May 27, 1983. PREVENTATIVE A CTION: The vendor has been informed of and has acknowledged the present problem. He has been advised to rigorously follow his QA manual for future SHNPP equipment. FINAL R EPORT: The vendor has been delayed in evaluating the results of CP&L weld repairs. The present schedule for a vendor evaluation is August 9, 1983. CP&L will review this evaluation and issue a final report on September 2,1983. _-}}
