U S. NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT REGION III July 13, 1979 IE Circular No. 79-13 REPLACEMENT OF DIESEL FIRE PUMP STARTING CONTACTORS Description of Circumstances:
On May 28, 1978, the Diesel Fire Pump failed to start remotely at Davis-Besse, Unit 1 facility operated by Toledo Edison Company. The cause for failure was defective starting contactors. A subsequent investigation into the cruse 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 Indus-trial Fire Pump Engines.
Discussion:
The investigation revealed that Cummins Engine Company issued a Service / Parts Topics No. 74T 13-3A announcing new components available for Industrial Fire Pumps (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, Cummins reco= 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 h.ve implemented the uective action recommended by Cu= mins.
Recommended Actions for Licensees' Consideration:
All holdern of ope eting licenses or construction permits should be aware of the po';ential problem of the type discussed above.
Because of the generic implicsticas in this matter, it is ecommended that both licensees of operating faciliries and holders of constructi, pernics conduct a review to determine if the sbote diesel fire pump engines are in use or planned for use at your f acility (1 es).
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 Cir:ular is required.
If yr _aquire additional information regarding these mar *.ers, contact the Director of the appropriate.
NRC Regional Office.
