l o l4 l l Condenser Circulating Water (CCW) Emergency Discharge System inoperable. Duringl g;3;lthe time the system was inoperable, the normal mode of condenser cooling was inl [olsll service using the CCW pumps.

If all station power was lost or the Keowee Dam l

l o l 7 l l System failed, the atmosphere relief valves were available to remove heat.

A short in the conductor caused CCW-8 to l l1l1 l l open. The valve was electrically closed and the system was reprimed. The l

l i 12 l l cable will be replaced. Future modifications will physically nrotect the I

l,;3ll cables, and a procedure will be written that provides a method of designating l l i l 4 l l the underground cable locations.
