6 personnel, no records were exmnined indicating that training programs had been conducted for nonsupervisory personnel whose activities affect quality, such as engineering, procurenent personnel. Those records, if available, will be examined in a subsequent inspection.
b.
PEDS has discontinued the practice of imposing 10 CFR Part 21 on its suppliers since the only product they (PEDS) manufacture for the commercial nuclear industry is supplied to one (1) customer, only.
This product, a 7.5 KVA static inverter, is manufactured from standard commercial stock products for the Westinghouse Nuclear Energy Systems Division. WNES contrac-turally retains the responsibility for final design approval, design change approval and final qualification testing of the inverter to meet applicable national codes and standards. WNES also examines production test data, burn-in data and QA data packages before granting release for shipment of static inverter products.
D.
Design Reviev/ Production Testing 1.
Objectives The objectives of this area of the inspection were to:
(a) Review customer procurement documents for PEDS design and production of static inverters for Class lE applications.

requirements are imposed on PEDS for static inverters for Class lE applications.
(c) Determine what type qualification, production and/or environ-
=ent testing is conducted by PEDS in the productian of static inverters.
(d) Determine what design, productiun, testing specification or a
1 procedures have been implemented by PEDS for the production of static inverters.
2.
Method of Acc:molishment The preceding objectives were accomplished by:
a.
Discussions with =arketing and applications engineering per-sonnel regarding the design. production testing, and documenta-tion requirements for static invertars provided for WNES.
.l
7 b.
Review of the custo=er (WNES) purchase order No. 546-GLP-248606, September 8,1976, (PEDS G.O. No. Ed-50036-AR6/L13) for four (4) 7.5 KVA Static Inverter Power Supply Systems.
Applicable Specifications referenced in the P.O. referenced above includes, WNES Specification G676573, Revision 5, en-titled, " Statics Inverter Power Supply System for Critical Single Phase Loads" dated March 13, 1975.
Review of~EEDS test data raport entitled, " Environmental Test c.
of 7.5 KVA Instrument Bus Inverter," dated June 22, 1978.
This test data, accumulated during a test conduc ted April 10-14, 1978, of a 7.5 KVA inverter, style No. 1738A94G12, assembled by PEDS order No. 30K2203-1, was authorized by WNES P.O. No.
546-LP-265708-SN for the environmental qualification of the generic static inverter for WNES for Class lE applications, d.
A review of production practices and test programs from the receipt, inspection and testing of incoming products to storage in stock, assembly of product kits, stuffing of printed circuit (?C) boards, pre-and post-inspection of soldered PC boards, functional testing of PC boards, assembly and testing of inverter modules, assembly of modules into in-verter cabinet and final functional testing of the inverter, including review a one hundred (100) hour burn-in test of an inverter that was in progress.
Activities at each produc-tion, inspection, assembly and test stations were being per-formed in compliance with applicable procedures which were available for review.
3.
Findings Within this area of the inspection, no deviations or unresolved items were identified.
Comments J
a.
PEDS completed the basic design for the inverter, which is manufactured for WNES, in 1972.
The design was approved and frozen by WNES. All subsequent design changes require WNES
- approval, b.
PEDS provides certified production tests for each inverter including a one-hundred (100) hour burn-in test.
PEDS is not contractually liable for the full qualification testing of the static inverters to meet Class lE applications.
According to-PEDS engineering and QA personnel "WNES has retained the responsibility for full qualification testing of the PEDS static inverters to meet applicable codes and standards i
f or Class lE applications. "
G *,
8 The WNES Equipment Specification G676573, Revision 5, imposed c.
on PEDS by the WNES P.O. No. 546-GLP-248606 (reference para-graph 2.b) does not require PEDS compliance to IEEE standards 323, and 344 for qualification and seismic testing, respectively, for static inverters.
