| UNANALYZED CONDITION THAT SIGNIFICANTLY DEGRADED PLANT SAFETY                |
|                                                                              |
| On May 3, 2002, approximately 20 gallons of water was spilled on the floor   |
| of the cable spreading room (CSR).  Some of the water leaked down into rooms |
| below the CSR floor, resulting in an electrical ground on the on the 125-VAC |
| Division 2 battery bus S1-2.  The S1-2 bus remained operable.  It has since  |
| been determined that the pathway for leakage through the floor of the CSR    |
| was cracks in the concrete due to abandoned concrete anchors, and through    |
| shrinkage cracks in the reinforced concrete floor slab.  Shrinkage cracks    |
| are also located in the 525' elevation floor above the Control Room.  These  |
| two floors are considered essential fire rated assemblies and are required   |
| to be "leak tight". These floors have not had a qualified paint/sealant      |
| applied that would render them "leaktight".  Other floors that are fire      |
| rated assemblies are believed to have had the appropriate paint/sealant      |
| applied, but this is being verified.  Should a fire system actuate, or       |
| develop a leak in either the CSR or the room above the Control Room, there   |
| is the potential for leakage through the floors to impact Division 1 or 2    |
| safety-related equipment in the rooms below.  A barrier impairment has been  |
| initiated for the CSR on May 6, 2002 and for the 525' elevation above the    |
| Control Room on May 7, 2002 with compensatory action to include these areas  |
| on an hourly fire/flood tour. With the hourly fire/flood tours in place, the |
| floors of the CSR and the room above the Control Room have been declared     |
| "operable but degraded" per formal assessment of operability, and no longer  |
| represent an unanalyzed condition that significantly degrades plant safety.  |
| The cracks associated with the abandoned anchor bolts have been sealed.      |
| Hourly fire/flood tours remain in effect until both floors have been         |
| properly sealed.                                                             |
|                                                                              |
| The NRC Resident Inspector has been notified of this event.                  |
|                                                                              |

|                                                                              |

| The licensee is retracting this event notification. It was originally        |
| postulated that due to the prevalence of unsealed concrete cracks, a design  |
| basis flooding scenario would create a significant amount of water leakage   |
| into critical equipment rooms below the floors. After further evaluation it  |
| has been concluded that flooding events in either room would result in       |
| minimal leakage into rooms below, and therefore this condition can not be    |
| characterized as an unanalyzed condition that significantly degrades plant   |
| safety. The CSR floor and the room above the Control Room are "operable but  |
| degraded." Hourly fire/flood tours will remain in effect until both floors   |
| have been properly sealed. The cracks responsible for the observed leakage   |
| for this event have been sealed. Columbia Generating Station will submit a   |
| voluntary Licensee Event Report on this issue due to its generic interest to |
| both the NRC staff and the nuclear industry.                                 |
|                                                                              |
| The licensee notified the NRC Resident Inspector.  The R4DO (Dale Powers)    |
| has been notified.                                                           |
