U" h 1988 Docket No. 99900871/88-01 EA 88-129 Mr. P. A. Zecos, President and Chief Executive Officer Elgar Corporation 9250 Brown Deer Road San Diego, California 92121
Dear Mr. Zecos:
This refers to the inspection conducted by Mr. J. J. Petrosino of this office on January 25-28, 1988, of your facility at San Diego, California and to the discussions of our findings with Mr. T. Erickson and members of your staff at the conclusion of the inspection.
This inspection was made as a result of the recurring problems experienced with Elgar 25KVA electrical inverters by the Palo Verde Nuclear Generating Station (PVNGS) units II and III.
The scope of the inspection was limited to a review of your 7.5 and 25KVA electrical inverter design changes. Areas examined during the inspection and our findings are discussed in the enclosed report. Within these areas, the inspection consisted of an examination of procedures and representative records, interviews with personnel, and observa-tions by the inspector.
During the inspection, it was found that the implementation of your QA program failed to meet certain NRC requirements. The most serious of these findings was the failure of Elgar to evaluate potentially reportable 10 CFR Part 21 deviations and design errors, or to notify its end users so they could cause an evaluation to be performed. Additionally, Elgar is not appropriately controlling its hardware design changes for its 7.5 and 25KVA electrical inverters. A review of Elgar design change documents revealed numerous examples where an independent review for technical adequacy was not performed.
l Furthermore, based on our review of your 7.5 and 25KVA inverters, it appears that technical reviews tc assess the collective impact of several design changes on a particular system function were not performed. The specific findings and references to the pertinent requirements are identified in the enclosures to this letter.
In accordance with the "General Statement of Policy and Procedure for NRC Enforce-ment Actions," 10 CFR Part 2 Appendix C (1988), the violation described in the enclosed Notice has been classified at a Severity Level III violation because silicone control rectifiers failed in actual use and if an evaluation of a deficiency known to Elgar had been perfonned it is likely a Part 21 report would have been required. However, pursuant to 10 CFR 21.61, the failure to perform the l
evaluation did not appear to be the result of a knowing and conscious failure to provide the required notice and so a civil penalty is not being imposed. Also enclosed is a Notice of Nonconformance which describes apparent weakness in your Dq l
program for compliance with 10 CFR Part 50, Appendix B.

Mr. P. A. Zecos June 3, 1988 The responses requested by this letter are not subject to the clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, PL 96-511.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of this letter and the enclosed inspection reports will be placed in the NRC's Public Document Room.
Should you have any questions concerning this inspection, we will be pleased to discuss them with you.
Sincerely,
