Dear Mr. Starostecki:

Enclosed is a final report in accordance with 10CFR50.55(e) for the problem concerning equipment qualification of the High Pressure Core Spray Diesel Generator.

This condition was reported to Mr. W. Baunack of the Region I office on Thursday, August 5,1982 and was followed by interim reports cc August ?l, 1982 anJ October 25, 1982.

Very truly yours,

NIAGARA M0 HAWK POWER CORPORATION NINE MILE POINT - UNIT 2 DOCKET N0. 50-410 Fina! Report for a Problem Concerning High Pressure Core Spray Diesel Generator Qualification Documentation Description of tne Preblem A Niagara Mohawk Power Corporation Quality Assurance Department review of the qualification dccumentaticn for the High Pressure Core Spray Diesel Generator System at General Electric-Nuclear Energy Business Organization in San Jose, CA was cunducted dJring the week of June 28, 1932.

The following conditions were observed:

1.

3. ring the production test. of the Hign Pressure Core Spray Diesel Generator, the ambient temperature of 122*F (50*C) specified in the purchase *.pecification data sneet, General Electric Document No.

?lA9236CS, yas rat attained.

Paragraphs 5.2.3.1 and 5.2.3.6 of IEEE 323-1971 require testing to the extremes of service conditions which includes tempature.

2; General Electric Document No. 21A9236, Paragraph 5.1.1.b requires vibration test data to demonstrate that the unit is free of excessive vibration during oper ation.

This cata was not included in the General Electric vibration test aata.

3.

Also, certain essential diesel auxiliary cc,mpon?nts (i.1, lube pump, cooling oil pump and starter solenoid valve) were not crecifically addressed es being adegi ately designed tc, witnstcnd :,ite scistic loads with no loss in structural integrity or function.

Analysis of Safety Implications As indicated below, adequate documentat fon has been i' rov;c'ed ro demonstral.e qualification of the Hign Pressure Core Spray Diesel Generator ior ti.e bait 2 specified environmental and seismic conditions in actor.pi.ce v.ith I2 E 323-1971 and IEEE 344-1971. Therefore, if this condit.:n tcd gons un A.e:ted, i

it would not have adversely affected th? safe operat. ice of f:ine dele Point Unit 2.

Corrective Actions General Electric has provided the fol?owing inforrution to resoive the above three deficien.ies:

1.

General Electria nas provided operating experieace ir.ftrmation to support the qualification of th? Higt Pressure Cc'e Spray Diesel Generator tu perforan its intended function at 50 C.

Thi: Operr.;ing experience is based on oneration of s1milar typ.: of diesels in arPas where the shelter temperaturer commonly exceed 50*C (Example; Abu Gnabi, United Arab E:nirates).

Cased o's General Electric's engineering judgment, the oper ating experi?qce providnd is appacable and envelopes the maximum d.s gn ambient temperatura for the Nine Mile Point Unit 2 Diesel Generator.

i m

.1 2.

General Electric has provided information which indicates that the ptcpose of the vibration test data was to verify there was no excessive or harmful vibration. Since none was observed, actual vibration readings /measurernents were not recorded or required.

It is General Electric's engineering position that the intended requirement of Paragraph 5.1.1.b of General Electric Specification 21A9236 were fulfilled.

3.

General Electric has provided a supplement to the original seismic qualification documentation for the Nine Mile Point Unit 2 High Pressure Core Spray Diesel Generator.

This suppleniental report demonstrates that essential diesel auxilia a compenents not specifically addressed in the original calculations arc 00cquately designed tc withstand the site seismic loads with no icss in structural integrity or fur.ctior..

This supplement furthcr demonstrates the adequacy of the Ursit 2 High Pressure Core Soray Diesci Generator to operate during and follcwing e design basis carthqu?Pe, I
