| 24-HOUR CONDITION OF LICENSE REPORT INVOLVING TECH SPEC REQUIREMENTS |
| |
| "On February 9, 2000, it was discovered that the Flux Multiplication Alarm |
| (which is used to mitigate boron dilution accidents) was not functional. It |
| was not recognized at that time that this caused the associated extended |
| range neutron detector to be inoperable. If an extended range detector is |
| inoperable in Modes 3, 4, and 5 the Technical Specifications requires that |
| operations be suspended involving positive reactivity changes. |
| |
| "On March 1, 2000 at 0017 hours Unit 1 entered Mode 3 as part of a shutdown |
| to support refueling activities. |
| Immediately following Mode 3 entry testing was performed which involves |
| raising control rods to perform drop |
| testing. Raising control rods constitutes positive reactivity which is |
| contrary to requirements of the Technical |
| Specifications. |
| |
| "This notification is being made pursuant to Operating License NPF-76 |
| Condition 2.G for operation or condition prohibited by Technical |
| Specifications." |
| |
| The licensee will inform the NRC resident inspector. |
| |
| * * * UPDATE AT 1417 ON 03/27/00 BY KEN TAPLETT TO JOLLIFFE * * * |
| |
| Further licensee review determined that the extended range neutron detector |
| in question had been operable during the positive reactivity change |
| activity. During the time of the original notification, the Flux |
| Multiplication Alarm was thought to be non-functional. A non-functional |
| Flux Multiplication Alarm causes the associated extended range neutron |
| detector to be inoperable. It was determined that the Flux Multiplication |
| Alarm was actually functional at the completion of surveillance testing |
| conducted on February 9, 2000. The surveillance procedure requires an alarm |
| reset prior to exiting the surveillance test which arms the Flux |
| Multiplication Alarm circuit thus making it functional. Although this step |
| was performed on February 9, 2000, the performers did not recognize at the |
| time that this corrected the perceived loss of alarm function. |
| |
| Prior to the February 9, 2000 surveillance test, the last satisfactory |
| performance of the Flux Multiplication Alarm surveillance was conducted on |
| November 16, 1999 with a grace period to March 10, 2000. Unit 1 entered |
| Mode 6 (where the requirement was no longer applicable) on March 3, 2000 and |
| has remained in that mode for a refueling and steam generator replacement |
| outage. A satisfactory surveillance test was conducted on March 16, 2000. |
| |
| The licensee plans to revise the test procedure to preclude recurrence of |
| this event. |
| |
| Based upon the above justification, the licensee desires to retract this |
| event. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| The NRC Operations Officer notified the R4DO Kriss Kennedy. |

| SECURITY REPORT |
| |
| A contact employee attempted to bring contraband into the Protected Area. |
| Immediate compensatory actions were taken upon discovery. The licensee |
| notified the NRC resident inspector. Contact the NRC Operations Center for |
| additional details. |
| |
| * * * UPDATE AT 1513 ON 03/27/00 FROM KIM AITKEN TO JOLLIFFE * * * |
| |
| Further licensee investigation revealed that there was no significant threat |
| to River Bend Station or the public and that the vendor employee had no |
| malevolent intent. After review of Reg Guide 5.62, NUREG 1304, and Generic |
| Letter 91-03, the licensee has determined that this event is not reportable |
| under 10CFR26, 10CFR50.72, 10CFR73.71, or 10CFR73, Appendix G.l.d criteria |
| and thus, the licensee desires to retract this event. The licensee has |
| discussed this event with Region IV security personnel and the NRC Resident |
| Inspector. The NRC Operations Officer notified the R4DO Kriss Kennedy. |

| FAILURE OF LOCAL LEAK RATE TEST. |
| |
| DURING LOCAL LEAK RATE TESTING(LLRT) OF THE "2G11-F004", DRYWELL FLOOR DRAIN |
| SUMP PRIMARY CONTAINMENT ISOLATION VALVE, IT WAS DETERMINED THAT THE VALVE |
| LEAKS AT A RATE GREATER THAN 30,000 ACCM(ACTUAL CUBIC CENTIMETERS/MIN) WHICH |
| IS GREATER THAN THE PROCEDURAL LIMITS. THIS IN COMBINATION WITH ITS |
| COMPANION( IN SERIES) ISOLATION VALVE(2G11-F003) WHICH HAD FAILED A PREVIOUS |
| LLRT AND WAS REPAIRED, BUT FAILED ITS RETEST, RESULTED IN THE TECH SPEC |
| LIMIT FOR 0.009L-SUB-A BEING EXCEEDED FOR BYPASS LEAKAGE. THE TEST WAS |
| PERFORMED ON 3/26 AND WAS EVALUATED THIS MORNING. |
| |
| THE RESIDENT INSPECTOR WAS NOTIFIED. |
