The crane collapse and the stator drop in … The crane collapse and the stator drop in the train bay ruptured an eight-inch diameter fire main in the turbine building. Operators secured the station fire pumps to stop the water flow into the turbine building, resulting in the complete unavailability of the firewater system. As compensatory measures, the licensee positioned a fire pumper truck on one side of the plant and staged three diesel-driven pumps inside the protected area. Through onsite interviews, the team determined that the pumper truck carried approximately one thousand gallons of water, and two of the three diesel-driven firewater pumps had no viable suction sources. The team determined the readily available fire hoses for the one diesel-driven pump with an available water source may not have been sufficient to provide adequate fire fighting capabilities inside the power block of either unit. The licensee isolated the ruptured fire main and restored the firewater system to service on the morning of April 1, 2013. The team identified that the Operations staff was largely unaware of the limited capability of the compensatory measures implemented during the period of time the firewater system was unavailable. The team concluded that additional inspection was needed to fully assess the effectiveness of the compensatory measures and the timeliness of the firewater system restoration: Unresolved Item URI 05000313; 368/2013011-06, Compensatory Measures for Firewater System Rupture.ory Measures for Firewater System Rupture. +
