At 1011 (CDT), during this flushing activity, the flushing hose ruptured and caused flooding in the Auxiliary Building that had the potential to affect safety related equipment needed for the current operating mode.

Specifically the EAL conditions were 'Flooding in the Auxiliary Building that has the potential to affect safety related equipment needed for the current operating mode.' Auxiliary Feedwater is required to be operable in Mode 1 for each unit.</br>The leak was immediately isolated (within 45 seconds of hose rupture) and remains isolated. Maintenance personnel are in the process of testing the 1A and 2A AF Pump motor to determine operability. The appropriate Tech Spec Action Statements have been entered on each Unit for the AF Pumps. The leak also caused the wetting of MCC (Motor Control Center) 132X1, which feeds the 1B AF Pump control power. The Unit 0 (Common) Component Cooling Pump feed breaker cubicle was also wetted. Investigation into these components are also in progress.</br>The licensee has entered Technical Specification LCO 3.7.5 Condition A which requires restoration of the one of the AF pumps within 72 hrs.
