CAROLINA POWER & LIGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT UNIT NO. 1 INTERIM REPORT AUXILIARY RELAY CABINETS ITEM 105 MAY 25, 1983 REPORTABLE UNDER 10CFR50.55(e)
SUBJECT:
Shearon Harris Nuclear Power Plant, Unit 1,10CFR50.55(e) 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.
DATE PROBLEM REPORTED:
On November 1, 1982, CP&L (N. J. Chiangi) notified the p
NRC (A. Hardin) that this item was potentially reportable under 10CFR50.55(e) but not 10CFR Part 21.
On November 30, j.
1982, CP&L (R. M. Parsons) notified the NRC (J. P. O'Reilly) that this item was, after further evaluation, potentially reportable under 10CFR21 also. More recent evaluation i
has determined that since CP&L QA did not accept the equipment through our QA program, it is potentially 4
l 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:
1A-SA, 1B-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 l
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 equip-ment pertaining to seismic qualification.
l i
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 the 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 HPES.
4.
HPES has requested the vendor to evaluate the deficiencies as identified by the DDR and the HPES analysis. HPES letter to the vendor is H0-83165.
FINAL REPORT:
A follow up report will be issued by July 29, 1983, regarding vendor analysis. If the vendor analysis concurs with HPES evaluation, the report will be final.
