20555 IE Circular No. 79-13 Date:

July 16, 1979 Page 1 of 1 REPLACEMENT OF DIESEL FIRE PUMP STARTING CONTACTORS Description of Circumstances:

On May 28, 1978, the Diesel Fire Pump failed to start remotely at Davis 8 esse, Unit 1 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 Cummins Industrial Fire Pump Engines.

Discussion:

The investigation revealed that Cummins Engine Company issued a Service / Parts Topics No. 74T 133A announcing new components available for Industrial Fire Pumps (NH2201F, N855F, N855F1, NT855F2 series engines) to improve operation of inline 6 cylinder Industrial Fire Pump Engines.

In this topic, Cummins recom-mends 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 recommended by Cummins.

Recommended Actions for Licensees' Consideration:

All holders of operating licenses or construction 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 holders 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 Cummins 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 with 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.
