APPENDIX B Elgar Corporation Docket No.: 99900871/90-01 San Diego, California L
l During an NRC'. inspection conducted on March 12 through 15, 1990, it war determined that certain of your activities were not conducted in accordance with NRC requirements which were contractually imposed on Elgar by purchase orders with NRC licensee's. These items are set forth below and have been classified as nonconformances to the requirements of 10 CFR Part 50, Appendix B.
A.
Criterion II,. " Quality Assurance Program," of Appendix B to 10 CFR Part 50 requires, in part, that a program be established to provide control over q
activities affecting the quality of structures, systems and components.
The program will also provide for indoctrination of personnel performing activities affecting quality.
Contrary to the above, five out of six Elgar Nuclear and Service Department employees who typically perform activities affecting the quality of nuclear-related systems and components had not been i doctrinated in the quality asstirance program (90-01-03).
B.
Criterion.III, " Design Control," of Appendix B to 10 CFR Part 50 requires, in part, that.the design basis for components :nd systems be correctly translatcd into drawings and instructions.
It also requires that control i
measures be established for the identification and control of design interfaces-and for coordination among participating design' organizations.
These measures shall include the establishment of procedures among participating design organizations for the review, approval, release, distribution, and revision of documents involving design interfaces. The design ' control measures shall provide for verifying or cnacking the adequacy of design, such as by performing design reviews, use of alternate simplified calculational methods or by a suitable testing program. The verifying process shall be performed by individuals other than those who a
performed the original design. Where 'a test program is used to verify the adequacy of a specific design or design change, it will include suitable qualification testing of a prototype un:t under the most adverse conditions.
Contrary to the above, Elgar failed to correctly translate electrical wiring' termination locations from the electrical schematic for a t
safety-related uninterruptable power supply (UPS) Drawing Number 528-428-61, Revision F, "Overall Schematic," into the associated wiring instruction for the UPS, Drawing Number 628-428-50, Revision M, " Wire List-UPS-[model]-103-1-132." Consequently, the UPS supplied to the Texas Utilities' Comanche Peak Steam Electric Station contained vendor wiring errors'(90-01-04).

malfunctions, deficiencies, deviations, nonconformances, defe dive
-material, and equipment are promptly identified and corrected.
Contrary 'to the above, the-inspection identified. that:
1.
.Elgar failed to implement adequate corrective actions for a-J previously. identified nonconformance involving the failure to assure that the design change review process provided for an independent review of the technical adequacy of the 7.5 kilo-volt ampere (KVA)
.and.25 KVA inverter engineering change notices (ECNs).
This issue was
-I previously identified.in NRC Inspection Report No. 99900871/88-01 as 1
Nonconformance~88-01-03. Specifically, Elgar failed to evaluate the following ECNs: ECN 1104. ECN 1397, ECN 1473. ECN.1493 ECN 1499 ECN1689,(90-01-05)..ECN 1796, ECN 1836, ECN 2212 ECN 3800, ECN 598 ECN 6216.

Elgar failed to establish measures to assure that component-relEted' l
deficiencies which are identified by Elgar field service representa-tives at.NRC-licensed facilities are appropriately dispositioned i
within.thecontroloftheElgarQAprogram(90-01-06).
