NIAGARA M0 HAWK POWER CDRPORATION WINE MILE POINT - UNIT 2 000(ET NO. 50-410 Interim Report for a Potentially Reportable Deficiency Under 10CFR50.55(e) Regarding HPCS Diesel Generator Qualification Documentation Description of Deficiency WPC conducted a QA review of the qualification documentation for the HPCS diesel generator system at GE-NEG in San Jose, CA, during the week of June 28, 1982. The following conditions were observed:

1. During the production test of the itigh Pmssure Core Spray (HPCS) diesel generator, the ambient temperature of 122*F (50*C) specified in the purchase specification data sheet, GE Document No. 21 A9236CB, was not attained. The ambient temperature during the testing did not exceed 96*F (35.5'C) at any time. Paragraphs 5.2.3.1 and 5.2.3.6 of IEEE 323-1971 require testing to the extren,es of service conditions.

2. The Vibration Test Data, requimd by GE Document No. 21 A9236, paragraph 5.1.1.b, to show the unit is free of excessive vibration during operation, was not included in the test report.

3. The test report does not include the following items required by IEEE 323-1971:

a. The variables to be measumd including accuracies (paragraph 5.2.3.2)

b. The number, type, and location of test monitors for each variable (paragraph 5.2.3.3)

c. The range, sequence, and combinations of environments to simulate the design basis event (paragraph 5.2.3.6)

d. Equipment mountings relative to performance (paragraph 5.2.3.7)

e. Cable connections and other mquimd appurtenances (paragraph 5.2.3.8)

f. Sumary, conclusions, and recommendations (paragraph 5.2.4.6)

4. Seismic analysis of the skid assembly does not clearly demonstrate

, operability of the assembly during and after a seismic event.

Although the analysis of the components covemd in the mports is comprehensive, there are apparent omissions. As an example, no analysis or justification for omitting the analysis for the starter solenoid valve is provided.

The matter is still under investigation. A final report will be submitted by November 1,1982.
