AUTOMATIC REACTOR SCRAM CAUSED BY TURBINE TRIP
The licensee reported that an automatic reactor scram occurred due to a turbine trip. The cause of the turbine trip is under investigation. Group 2 and 3 isolations occurred as expected during post scram conditions. The lowest reactor vessel water level was 0 inches. All systems functioned as designed.
The NRC Resident Inspector was notified.

NOTIFICATION UNDER 10 CFR PART 21 FOR LEAKING FUEL PUMP ON FAIRBANKS MORSE EMERGENCY DIESEL ENGINE
The following are the contents of a facsimile:
"This initial notification addresses the reporting requirements of 10 CFR 21.21(d)(3)(i) and provides preliminary information applicable to 10 CFR 21.21 (d)(4).
1. Name and address of the individual informing the Commission.
G.M. Dugger
Vice President Operations
Entergy Nuclear Operations, Inc.
Pilgrim Nuclear Power Station
600 Rocky Hill Road
Plymouth, MA 02360
2. Identification of the facility, the activity, or the basic component supplied for such facility or such activity within the United States which fails to comply or contains a defect.
Facility Pilgrim Nuclear Power Station
Component Fuel Injector Pump for ALCo (Fairbanks Morse), model 251 F, Emergency Diesel Generator, Part Number 23200127, Serial Number 9611071
3. Identification of the firm constructing the facility or supplying the basic component which fails to comply or contains a defect.
Supplier Coltec Industries
Fairbanks Morse Engine Division
701 White Avenue
Beloit, WI 53511-5492
4. Nature of the defect or failure to comply and the safety hazard, which is created or could be created by such defect or failure to comply.
The fuel injector pump was found to be leaking excessively through a nameplate rivet hole that had been drilled through-wall in the pump body. The drilled hole allowed fuel to leak through the pump body.
This fuel injector pump was being installed on a safety-related emergency diesel generator. It was through visual observation of the pump during the post work test that the fuel leak through the nameplate rivet hole was detected. If the leak had not been identified during the post work test, the leak could have gone unnoticed during subsequent emergency diesel generator operation. The failure of the fuel injector pump could have adversely impacted emergency diesel generator operation and prevented the emergency diesel generator from being able the supply all of the necessary accident loads.
5. The date on which the information of such defect or failure to comply was obtained.
The defect was discovered during post work testing on July 19, 2002 while the emergency diesel generator was tagged out of service for the overhaul that installed the subject fuel injector pump. A determination that the defect could create a substantial safety hazard was completed on September 12, 2002.
In accordance with 10 CFR 21.21 (a)(3) and Pilgrim Station procedure, the Pilgrim Site Vice President was notified of the conclusion. The notification was made on September 17, 2002.
6. In the case of a basic component which contains a defect or fails to comply, the number and location of all such components in use at, supplied for, or being supplied for one or more facilities or activities subject to the regulations of this part.
At Pilgrim Station, there are two emergency diesel generators and one Station Blackout Diesel Generator (SBODG). There are 18 fuel injector pumps installed on each emergency diesel generator and 12 fuel injector pumps on the SBODG. Except for the defective fuel injector pump that was installed while the emergency diesel generator was tagged out service for overhaul, none of the fuel injector pumps installed on either emergency diesel generator or the SBODG have exhibited a similar leak (through-wall rivet hole leak in the pump body).
7. The corrective action, which has been taken, is being, or will be taken; the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action.
The fuel injector pump that contained the through-wall rivet hole in the pump body was removed from the emergency diesel generator and was replaced with a spare fuel pump. The spare fuel pump was visually inspected for leak tightness when the emergency diesel generator was post work tested after the defective pump was replaced. The emergency diesel generator post work testing was completed With satisfactory results and returned to operable status on July 21, 2002.
The defective pump was not retained.
There are currently no (zero) fuel injector pumps located in the Pilgrim Station warehouse.
8. Any device related to the defect or failure to comply about the facility, activity, or basic component that has been, is being, or will be given to purchasers or licensees.
Pilgrim Station discussed the condition of the defective pump on September 16, 2002, with the pump supplier. The supplier acknowledges modifying the mounting of the nameplate label to the pump prior to supply. Pilgrim Station has not supplied any spare fuel injector pumps to a purchaser or other licensee."
The Licensee has notified the NRC Resident Inspector.
