| SINK HOLE IN SITE STABILIZATION POND |
| |
| "The site stabilization pond has developed a sink hole which has created a |
| partial bypass of the normal treatment system from an unauthorized release |
| point. The stabilization pond receives water pumped from a Storm Drain Basin |
| which collects storm drainage from various areas around the site. This |
| release from an unauthorized discharge point requires notification to the |
| State of North Carolina in accordance with our NPDES permit. This report |
| initiated per [50.72(b)(2)(xi)] due to State of North Carolina |
| notification." |

| INOPERABLE SECONDARY CONTAINMENT |
| |
| "On 3/20/03 at 0015 hours during performance of Secondary Containment |
| drawdown testing, it was determined that the Technical Specification maximum |
| allowed combined flowrate of 2885 SCFM for Zone 1 and Zone 3 was exceeded. |
| The average flow for the two zones was approximately 3000 SCFM. The |
| condition required the Station to declare both zones inoperable, and placed |
| Unit 1 in a 4 hour LCO to restore Secondary Containment. Unit 2 is already |
| in Mode 5, however the condition would have prevented all additional fuel |
| moves. The Standby Gas Treatment System was capable of maintaining the DP |
| requirement of 0.25 " vac. water gauge during the test. By 0330 |
| investigation had reduced flow from the two zones to approximately 2600 |
| SCFM, and the LCO was exited. The inoperability of Secondary Containment is |
| a loss of an entire Safety Function that is needed to control the release of |
| radioactive material, and is reportable under 10CFR50.72(b)(3)(v)(c)." |

| The licensee notified the NRC Resident Inspector. |
