Subject: FAILURE OF THE APPENDIX-R EMERGENCY DIESEL GENERATOR            

Discussion:

On November 3, 1995, during the monthly performance test of the          
Appendix R emergency diesel generator (EDG), the EDG failed to function  
properly. Approximately 50 minutes into the 60 minute run, the output    
decreased from 2500 KW to 500 KW.  The operator unsuccessfully attempted 
to control the output with the governor control switch. Load then        
increased to approximately 1000 KW and then dropped to 0 KW.  The        
operator opened the output breaker and secured the machine.  The operator
reported hearing a loud pop and mechanical sounds during the event.      
                                                                         
Troubleshooting revealed the turbocharger had seized. Further inspection 
identified a broken rotor blade, indications of rubbing of the turbine   
and compressor blades on the case, and indications of bearing material in
the oil. The exact sequence of the damage is still under investigation by
the turbocharger vendor.                                                 
                                                                         
NYPA is currently evaluating options to repair or replace the            
turbocharger.  Additionally, engine inspections, including internal      
inspection of the cylinders, is planned.                                 
                                                                         
The Appendix-R EDG is an ALCO model 18-251, rated at 2500 KW.  The EDG is
just over 10 years old with only 108 hours of run time on the engine.    

Regional Action:

Routine follow-up by the resident inspectors as well as review of the    
cause of the turbocharger failure by a DRS specialist inspector.
