There was one (1) | | fatality and three (3) injuries which required hospitalization. | | Notifications of the vehicle accident were made to Pike County (Ohio) | | Sheriff's Office. Once it was determined that the accident involved a | | fatality DOE-OROC, and DOE-HQ were also notified. | | | | "This PORTS notification to 'other government agencies' requires | | notification to the NRC as a 4-hour NRC Event Report." | | | | The NRC resident inspector was informed of this report. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 38185 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: PRAIRIE ISLAND REGION: 3 |NOTIFICATION DATE: 08/03/2001| | UNIT: [1] [] [] STATE: MN |NOTIFICATION TIME: 22:56[EDT]| | RXTYPE: [1] W-2-LP,[2] W-2-LP |EVENT DATE: 08/03/2001| +------------------------------------------------+EVENT TIME: 20:40[CDT]| | NRC NOTIFIED BY: JOEL SORENSEN |LAST UPDATE DATE: 08/04/2001| | HQ OPS OFFICER: STEVE SANDIN +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: UNUSUAL EVENT |JOHN MADERA R3 | |10 CFR SECTION: |HERB BERKOW NRR | |AAEC 50.72(a) (1) (i) EMERGENCY DECLARED |JOSEPH HOLONICH IRO | |ARPS 50.72(b)(2)(iv)(B) RPS ACTUATION - CRITICA|JIM DYER RA | |AESF 50.72(b)(3)(iv)(A) VALID SPECIF SYS ACTUAT|JON JOHNSON NRR | |DDDD 73.71 UNSPECIFIED PARAGRAPH |ZAPATA FEMA | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 A/R Y 20 Power Operation |0 Hot Standby | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | UNIT 1 DECLARED AN UNUSUAL EVENT DUE TO A FIRE LASTING GREATER THAN 10 | | MINUTES | | | | A fire occurred in the 4KV Bus 12 while realigning the electrical power | | supplies from the 1 Reserve Transformer to the 1 Main Transformer during | | power ascension. Bus 12 supplies both the 12 Reactor Coolant Pump and the | | 12 Feedwater Pump which were secured. The 11 Reactor Coolant Pump was also | | secured placing the unit in natural circulation. Auxiliary Feedwater Pumps | | 11 and 12 are in service (autostarted on lo-lo SG level) supplying both | | Steam Generators (SG) as normal for a reactor trip. The Main Condenser is | | in-service for decay heat removal. | | | | The licensee is in the process of electrically isolating Bus 12. The Red | | Wing Fire Department is onsite responding to the fire which has not been | | confirmed extinguished at the time of this report. | | | | The cause of the reactor trip and the fire is unknown. | | | | The licensee informed state/local agencies and the NRC resident inspector. | | | | * * * UPDATED AT 0016 EDT ON 8/4/2001 BY SCOTT WHITSON TO FANGIE JONES * * | | * | | | | The licensee reported that 2 employees were treated for heat exhaustion on | | site and another employee was transported to a local hospital at 2255 CDT | | for the same reason.

The licensee notified the NRC Resident Inspector. | | | | The R3DO (John Madera), NRR EO (Herb Berkow), and FEMA (Zapata) have been | | notified. | | | | * * * UPDATED AT 0325 EDT ON 8/4/2001 BY MIKE SLEIGH TO FANGIE JONES * * * | | | | The licensee reported that at the beginning of the Unusual Event a | | safeguards degradation related to the area boundary took place. | | Compensatory measures were taken upon discovery. | | | | The licensee notified the NRC Resident Inspector and intends to notify R3 | | IAT (James Creed). The R3DO (John Madera) was notified. | | | | Refer to the HOO Log for details. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 38186 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: DIABLO CANYON REGION: 4 |NOTIFICATION DATE: 08/04/2001| | UNIT: [1] [2] [] STATE: CA |NOTIFICATION TIME: 19:55[EDT]| | RXTYPE: [1] W-4-LP,[2] W-4-LP |EVENT DATE: 08/04/2001| +------------------------------------------------+EVENT TIME: 15:22[PDT]| | NRC NOTIFIED BY: DAVID BAHNER |LAST UPDATE DATE: 08/04/2001| | HQ OPS OFFICER: STEVE SANDIN +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |CHUCK CAIN R4 | |10 CFR SECTION: |HERB BERKOW NRR | |AESF 50.72(b)(3)(iv)(A) VALID SPECIF SYS ACTUAT| | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | |2 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | AUTOMATIC START OF BOTH UNITS DIESEL GENERATORS DUE TO A LOSS OF START-UP | | POWER | | | | "Electrical fault caused loss of Start-up Power to both units. This caused | | all six [6] diesel generators on both units to automatically start." | | | | Circuit breaker CB212 which supplies 230KV start-up power to both units | | opened due to an unidentified electrical fault. Initial indication was a | | loss of power to outbuildings onsite followed about twenty-two (22) minutes | | later with a loss of power to the Start-up transformers. Investigation | | found the grounding fuses on the Unit 1 side open. Should a unit trip occur | | while in this condition, RCS cooldown by natural circulation would be | | required. | | | | Both units are in Tech Spec LCO 3.8.1 Condition 'A' which requires | | restoration of start-up power within 72-hours or unit shutdown; mode 3 (hot | | standby) in the following 6-hours followed by mode 5 (cold shutdown) | | 36-hours later. The licensee is performing a maintenance and engineering | | evaluation to determine if start-up can be restored by closing a cross-tie | | breaker from Unit 2. | | | | None of the diesel generators loaded and all have been secured and returned | | to standby. | | | | The licensee informed the NRC resident inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 38187 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: HATCH REGION: 2 |NOTIFICATION DATE: 08/05/2001| | UNIT: [1] [2] [] STATE: GA |NOTIFICATION TIME: 22:25[EDT]| | RXTYPE: [1] GE-4,[2] GE-4 |EVENT DATE: 08/05/2001| +------------------------------------------------+EVENT TIME: 21:30[EDT]| | NRC NOTIFIED BY: ALAN WOLFE |LAST UPDATE DATE: 08/05/2001| | HQ OPS OFFICER: BOB STRANSKY +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |KERRY LANDIS R2 | |10 CFR SECTION: | | |ACOM 50.72(b)(3)(xiii) LOSS COMM/ASMT/RESPONSE| | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | |2 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | NOAA WEATHER RADIO SYSTEM INOPERABLE | | | | The NOAA weather radio system was determined to be inoperable at 2130 EDT. | | The radio system is used as part of the licensee's prompt notification | | system.
