Subject: PRELIMINARY NOTIFICATION OF EVENT (PNO-III-96-031) UPDATE       

Discussion:

The licensee's investigation of the loss of offsite power to Unit 1 on   
May 23, 1996 determined that the cause of the station auxiliary          
transformer (SAT) 142-2 failure was moisture intrusion into the "B" phase
of the Unit 1 SAT bus duct. Offsite power has been restored to Unit 1    
through SAT 142-1. The licensee is investigating water hammer experienced
approximately six hours after the reactor trip, during realignment of the
main feedwater system, which may have affected 14 pipe hangers and       
snubbers. The licensee installed a temporary modification to supply      
electrical power to the OB nonessential service water pump from Unit 2;  
this pump is normally powered from Unit 1. This arrangement will ensure  
that each unit has the capability to power a non-essential service water 
pump.                                                                    
                                                                         
The licensee secured from the Unusual Event at approximately 2:00 p.m.,  
Friday, May 24, 1996. Unit 2 reactor startup is planned for Wednesday    
morning, May 29, 1996.                                                   

Regional Action:

The NRC Senior Resident Inspector is monitoring the licensee's response  
to the event. Regional specialist inspectors and additional resident     
inspectors carefully monitored the licensee's followup of the event.
