| HPCI INOPERABLE |
| |
| During QCOS 2300-28 'HPCI Turning Gear Logic Functional Test' the HPCI |
| turning gear failed to engage. The test was stopped and HPCI was placed on |
| the turning gear from a normal standby lineup and removed from the turning |
| gear using QCOP 2300-13 'HPCI Turning Gear Operation'. Per analysis the |
| HPCI turbine must be able to be remotely placed on the turning gear. Since |
| HPCI failed to go on gear during the logic test it was declared inoperable |
| at 0420. A 14 day LCO was centered per Tech Spec 3.5.A action 3. |
| |
| The Licensee will notify the NRC resident inspector. |

| UNUSUAL EVENT DECLARED AT 0555 DUE TO AN IDENTIFIED REACTOR COOLANT LEAK. |
| |
| THE LETDOWN STORAGE TANK BYPASS VALVE (3HP14) FAILED IN AN INTERMEDIATE |
| POSITION. APPROXIMATELY 45 GPM OF RCS WATER IS BEING BLED THROUGH THE |
| VALVE INTO THE DE-LITH DEMINERALIZERS. THE PLANT IS STABLE AT 80% POWER. |
| VALVE 3HP14 IS AN MOV ON A 2 1/2" LINE. THE 45 GPM OF FLOW IS CONSIDERED |
| "RECOVERABLE" RCS LEAKAGE. |
| |
| THE EVENT OCCURRED AT 0555 AND THE CURRENT LINEUP WAS REACHED AT 0604. THE |
| LICENSEE WILL REMAIN IN THE UNUSUAL EVENT UNTIL THEIR ENGINEERING DEPARTMENT |
| DETERMINES THAT THEY CAN REMAIN IN THIS LINEUP WHILE REPAIRS ARE MADE TO |
| 3HP14. |
| |
| THIS EVENT IS SIMILAR TO EVENT 36543 WHICH OCCURRED ON 12/27/99. THAT EVENT |
| LED TO REPAIRS ON 3HP14. THE MOTOR HAD BECOME UNCOUPLED FROM THE VALVE AND |
| WAS REPAIRED. IT IS NOT KNOWN NOW WHETHER THE SAME FAILURE MECHANISM HAS |
| BEEN REPEATED DURING THE CURRENT EVENT. |
| |
| THE RESIDENT INSPECTOR HAS BEEN NOTIFIED ALONG WITH STATE AND LOCAL |
| AGENCIES. |
| THERE WILL BE NO PRESS RELEASE. |

| THE UNUSUAL EVENT WAS TERMINATED AT 0713. THE LICENSEE WILL INFORM THE NRC |
| RESIDENT INSPECTOR. THE HOO NOTIFIED R2DO (CHRISTENSEN); EO (STROSNIDER); |

| SOME KAOWOOL FIRE BARRIERS OUTSIDE 10CFR50 APPENDIX R DESIGN BASIS |
| |
| "V.C. SUMMER HAS BEEN PERFORMING CONFIRMATORY TESTING ON KAOWOOL TRIPLE WRAP |
| FIRE BARRIERS BASED ON SECY 99-204 ISSUES. PRELIMINARY RESULTS INDICATE |
| THAT SOME CABLE/CONDUIT APPLICATIONS DO NOT MEET APPENDIX R III.G.2 |
| REQUIREMENTS (FREE OF FIRE DAMAGE FOR ONE HOUR). THESE APPLICATIONS INCLUDE |
| SMALL OPEN AIR CONDUIT (LESS THAN OR EQUAL TO 1"), AIR DROPS AND SMALL CABLE |
| TRAYS (LESS THAN OR EQUAL TO 6" x 6"). OTHER APPLICATIONS PERFORMED |
| ACCEPTABLY BASED ON PRELIMINARY REVIEW OF THE TEST DATA. V.C. SUMMER IS |
| CURRENTLY COMPARING THE TEST CONFIGURATIONS TO ACTUAL PLANT CONFIGURATIONS |
| TO DETERMINE AFFECTED AREAS. AS A CONSERVATIVE MEASURE A ROVING FIRE WATCH |
| WAS ESTABLISHED ON ALL APPENDIX R AREAS UTILIZING KAOWOOL. ADDITIONAL |
| ACTIONS WILL BE BASED ON FURTHER ENGINEERING EVALUATIONS." |

| 1-HOUR SECURITY REPORT INVOLVING HISTORICAL ACCESS AUTHORIZATION PROGRAM |
| VIOLATION |
| |
| "During performance of a Plant Evaluation Checklist (PEC OB 99-1157) on the |
| NRC Performance Indicator for Physical Protection Area a historical error |
| was discovered pertaining [to] access authorization. It was discovered that |
| unescorted access was authorized to an individual, from 11/10/95 to 1/16/96. |
| However on 1/11/96 information was received that had it been properly |
| investigated would have caused denial of unescorted access at that time. |
| |
| "This event is reportable as a one-hour report pursuant to 10 CFR 73.71 as |
| an Access Authorization (AA) program violation as stated in an NRC letter |
| from LeMoine J. Cunningham, Chief Safeguards Branch USNRC to the NRC Regions |
| chief, dated May 19, 1995. In the letter Mr. Cunningham states that events |
| involving AA program failure are reportable, and a 30 day written report |
| required." |
| |
| The licensee will inform the NRC resident inspector. |

| REACTOR TRIP FROM MODE TWO |
| |
| "Plant Vogtle Unit 2 was in a reactor startup following repair of a |
| Feedwater Heater. During withdrawal of Control Bank B to 85 steps, Control |
| Bank B rod B6 became misaligned from Its bank by Digital Rod position |
| indication System (DRPI) indication and the demand step counters. The Rod |
| Control System Malfunction abnormal operating procedure was entered and the |
| reactor was manually tripped at 0456 hours EST due to a misalignment of |
| greater than 12 steps between DRPI and the demand step counters. All rods |
| inserted as expected during the trip and no other anomalies were noted. The |
| reactor is currently stable in Mode 3." |
