U.S. NUCLEAP REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT REGION III July 13, 1979 IE Circular No. 79-13 REPLACEMENT OF DIESEL FIRE PUMP STARTING CONTACTOP

~

Description of Circumstances:

On May 28, 1978, the Diesel Fire Pump failed to start remotely at Davis-Besse, Unit I facility operated by Toledo Edison Company. The cause for failure was defective starting contactors. A subsequent investigation into the cause of a similar failure on January 18, 1978, at Commonwealth Edison Company's Dresden 2/3 Diesel Fire Pump identified a generic problem with Cu= ins Indus-trial Fire Pump Engines.

Discussion:

The investigation revealed that Cu= ins Engine Company issued a Service / Parts Topics No. 74T 13-3A announcing new components available for Industrial Fire Pu=ps (NH-220-1F, N-855-F, N-855-F1, NT-855-F2 series engines) to improve operation of inline 6 cylinder Industrial Fire Pump Engines.

In this topic, Cumins reco= ends that when replacing the 118848 magnetic switch and 199573 DC relay contactor, use the new 217588 magnetic switch. The new design component has a 6 ampere draw whereas the old combination has approximately 3 amperes draw. Davis Besse and Dresden sites have implemented the corrective action reco= mended by Cu= mins.

Recommended Actions for Licensees' Consideration:

All holders of operating licenses or constrt..: tion permits should be aware of the potential problem of the type discussed above.

Because of the generic implications in this matter, it is recommended that both licensees of operating facilities and holdera of construction permits conduct a review to determine if the above diesel fire pump engines are in use or planned for use at your facility (ies).

If these engines are in use or planned for use, determine if the Cu=1ns type 118848 Magnetic Switch and 199573 DC relay contactors are also employed.

For those engines which have these components, develop a pro-gram for their replacement W.th the new 217588 Magnetic Switch.

No written response to this Circular is required.

If you require additional information regarding these matters, contact the Director of the appropriate NRC Regional Office.
