NIAGARA M0 HAWK POWER CORPORATION NINE MILE POINT - UNIT 2 DOCKET N0. 50-410 Interim Report for a Problem Concerning the High Pressure Lube Oil Hose of the Diesel Generators (55(e)-85-ll)
Description of the Problem The problem concerns the high pressure lube oil hose of the standby diesel generators furnished by Cooper Energy Services. During testing and inspection activities at the Nine Mile Point Unit 2 site for the Division I standby diesel generator (2EGS*EGl), a damaged lube oil line was discovered. A lube oil hose which feeds the timing chain tightener sprockets was observed to have an approximately 1/4 in. square hole worn into it. A subsequent inspection of the Division II standby diesel generator (2EGS*EG3) indicated that the subject line in this diesel was also heavily abraded, but a hole was not visible.
Since neither of these engines have been run at the site, the damage is believed to have occurred during testing at the vendor's facilities.
This matter is still under investigation and a final report will be submitted by June 14, 1985.
