Subject: AREA FLOODING DUE TO FIRE MAIN MAINTENANCE WORK                 

Discussion:

A six-inch fire main break occurred at the Peach Bottom Atomic Power     
Station (PBAPS) at about 9:30 a.m., on August 21, 1998. The break        
occurred while performing maintenance work on a fire-hydrant located     
south of the water treatment plant and in the vicinity of the Unit 2     
Service Water/Circulating Water Pumphouse Structure. Excessive water     
accumulation outside of the pumphouse occurred due to clogged storm      
drains. Although the leak was not completely isolated, leakage was       
controlled at 50 gpm.                                                    
                                                                         
Water seepage also occurred through various electrical conduit           
penetrations near or at floor level inside of the Emergency Service Water
(ESW) and High Pressure Service Water (HPSW) pumprooms in the pumphouse  
structure. Water flow through conduit routed to the diesel-driven and    
motor-driven fire-pumps was also identified. Wetted components were      
limited to cables located within the affected conduits, routed in        
underground duct banks. The operability of the ESW/HPSW systems was not  
adversely impacted because the affected cables are qualified for a wet   
environment. The line break and flooding conditions were corrected on    
August 23.                                                               
                                                                         
PECO engineering continues to review the impact and ramifications of this
event in light of a design based flood event.                            

Regional Action:

The resident staff is continuing to follow-up on PECO's activities. The  
Division of Reactor Safety is monitoring the Licensee's activities.
