A. Schwencer, Chief Licensing Branch ¹2 United States Nuclear Regulatory Commission Washington, DC 20555
Dear Mr. Schwencer:
Re:
Nine Mile Point Unit 2 Docket No. 50-410 Enclosed is information relating to the Nine Mile Point Unit 2 diesel generators.
Specifically, this information shows a comparison of the Nine Mile Point Unit 2 diesel generators and selected diesel generators at other units which demonstrates that our diesel generators are similar.
We believe that the Unit 2 diesel generators, as shown on the attached
- tables, are essentially the same as those previously tested during preoperational testing at other units.
Specifically, IEEE 387 indicates that diesel generators that are essentially the same and have been previously
- tested, need not be service qualified.
Therefore, the 300 Diesel Generator Start Test need not be performed at our plant.
On this basis, we request authorization from the Nuclear Regulatory Commission to exclude this testing from our current preoperational test program.
To ensure that your decision on this matter does not affect our preoperational test
- program, we would appreciate your immediate consideration and approval by April 1, 1984.
Very truly yours, CVM/NLR:ja Enclosure C.

NMP2 DIVISIONS I II AND III STANDBY-DIESEL GENERATOR C MPLIANC.WITH REGULATORY GUIDE 1.9 REVISION 2 DATED DECEMBER-1979 The Division I and II diesel generators are Cooper Energy Services Model KSV-16-T.
Commonwealth Edison Company's Zion Station and Pennsylvania Power and Light Company's Susquehanna Station also utilize CES KSV-16-T diesel generators for standby service.
Both Commonwealth Edison Company and Pennsylvania Power and Light have performed a successful Regulatory Guide 1.9, Start and Load Acceptance gualification Test (Section C.13, 300 Start Test) on these Zion and Susquehanna KSV-16-T diesel generators.
A comparison of Nine Mile Point Unit 2, Zion and Susquehanna KSV-16-T standby diesel generators follows on Attachment 1,
Pg. l.
For the Divisions I and II diesel generators, the differences in total Wk2 (Item 9) and BMEP (Item 6) are favorable to Unit 2 with regard to starting capability.
The Unit 2 units have a higher continuous output rating.
All other key parameters tabulated are identical for the three stations.
Both the Divisions I and II Cooper Energy Services standby diesel generators were shop-tested by the system vendor for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at their 4840-kW 2-hour, start-time rating.
However, during this stop test, these units were not run at full load immediately before or preceding the 2-hour, 4840-kW test.
In separate shop tests, each of these standby diesel generators were run at full load (4400 kW) for a 4-hour period.
The Cooper Energy Services KSV-16-T and KSV-20-T diesel generators are used extensively as standby units in the commercial nuclear industry.
Cooper Energy Services's LSV-16 diesel engine is widely used in many applications outside the nuclear industry.
This engine is a slower speed predecessor of the KSV-16-T model used at Nine Mile Point Unit 2; however, it is very similar to the KSV-16-T model in overall design.
Due to the reasons explained above, it is Niagara Mohawk Power Corporation's position that a Regulatory Guide 1.9, Load Capability gualification Test (Section C.14) and a Start and Load Acceptance gualification Test (300 Start Test) are not required for the Divisions I and II diesel generators.
These tests are type tests required to confirm prototype standby diesel generator operating capability.
Niagara Mohawk Power Corporation believes that previous industry experience, as described above, warrants that these tests need not be performed on the Divisions I and II diesel generators.
All other Regulatory Guide 1.9, Revision 2 requirements will be met for the Divisions I and II standby diesel generators.
The Division III diesel generator is GM-EMD Model No. 20-645E4.
Commonwealth Edison Company's LaSalle County - Unit 1 Station also utilizes GM-EMD Model No. 20-645E4 diesel generator for standby service.
Attachment 1,
Pg.
2 is a comparison of the Nine Mile Point Unit 2 and the LaSalle 1 standby diesel generators.
