HIGH PRESSURE COOLANT INJECTION OVERSPEED TRIP MECHANISM FAILED TO RESET
"The High Pressure Coolant Injection system (HPCI) over-speed trip tappet did not reset as expected during the trip tappet test after securing from a successful HPCI operability run, thereby preventing a re-start of the HPCI system. The Automatic Depressurization System (ADS), Core Spray sub-systems, Low Pressure Coolant Injection (LPCI) and the Reactor Core Isolation Cooling (RCIC) systems are operable."
The unit is in a 14 day LCO for this event. The licensee will notify the NRC Resident Inspector.
* * * RETRACTION FROM MIKE PLETCHER TO JOE O'HARA AT 1130 ON 9/28/06 * * *
"NRC Notification 42810 was conservatively made to ensure that the Eight-Hour Non-Emergency reporting requirements of 10CFR50.72 were met pending the evaluation of condition observed with the High Pressure Coolant Injection (HPCI) Overspeed Trip reset feature that was discovered while performing scheduled testing for the HPCI System.
"During surveillance testing on 08/28/06, the HPCI System was started and satisfied the Technical Specification requirements designed to demonstrate HPCI System Operability. Subsequently, while testing the specific components of the system, the HPCI Overspeed Trip functioned as expected, but would not reset when manually depressed (locally). The Shift Manager declared the system inoperable and remained in the Limited Condition of Operation (LCO) that was entered prior to commencing the testing activities.
"Subsequent investigation determined that the reset function of the HPCI turbine overspeed trip device is not required to support HPCI from performing the system safety functions as described in the station design and licensing basis.
"ENS Event Number 42810, made on 08/28/06, is being retracted."
The licensee notified the NRC Resident Inspector. The R1DO(Hott) has been notified. |

AGREEMENT STATE REPORT - TRAFFIC ACCIDENT INVOLVING A TRUCK CARRYING RADIOACTIVE MATERIAL
The State provided the following information via email:
"The Division of Radiation Health (DRH) received notification on 9-22-06 from Mississippi Emergency Management Agency about a traffic accident that occurred at 6:00 AM on Highway 43 North of Picayune, MS. The vehicle was delivering radiopharmaceuticals to area hospitals and clinics. The road was wet due to rain and the driver lost control of vehicle and collided with 2 other vehicles. Several of the shipping containers were ejected from the vehicle and some of the contents were deposited outside the shipping containers. Local sheriff department and fire departments responded to the accident scene. DRH responded to the scene of the accident as well as Cardinal Health personnel. Cardinal Health personnel discovered that no contamination had leaked from the containers and no personnel were contaminated. Vehicle was transporting 6 boxes (ammo boxes used as shipping containers) containing a total of 892 millicuries of Technetium-99m and Xenon-133. Some boxes contained used doses that had already decayed to near background radiation levels."

TECHNICAL SUPPORT CENTER HVAC REMOVED FROM SERVICE FOR MAINTENANCE
"On 9/27/2006, the HVAC for the Hatch Nuclear Plant's Technical Support Center (TSC) was removed from service for planned preventive maintenance and inspections and testing activities. These work activities are planned to be performed and completed within a 12 hour work shift. During the time these activities are being performed, the TSC air handling unit, TSC condensing unit, TSC filter train and the fan unit for the TSC filter train will not be available for operation. As such, the TSC HVAC will be rendered non-functional during the performance of this work activity.
"If an emergency condition requiring activation of the TSC occurs during the time these work activities are being performed, then contingency plans call for utilization of the TSC as long as radiological conditions allow. The site Technical Support Center activation procedure provides instructions to direct TSC management to the Control Room and TSC support personnel to the Simulator Building to continue TSC activities if it is necessary to relocate from the TSC so that TSC functions can be continued.
"This event is reportable per 10CFR50.72 (b)(3)(xiii) as described in NUREG-1022, Rev. 2 since this work activity affects an emergency response facility for the duration of the evolution."
The licensee will notify the NRC Resident Inspector.
* * * UPDATE RECEIVED FROM ANDY DISMUKE TO JOE O'HARA AT 1014 ON 9/28/06 * * *
"The maintenance outage affecting the normal power supply for the TSC HVAC was not completed yesterday (September 27, 2006) as originally scheduled. The work schedule called for the normal power supply to the TSC HVAC to be returned to service within 12 hours; however, problems occurred in the functional test of the associated bus that provides the normal power supply to the TSC HVAC. During the functional test, the bus successfully swapped from normal supply to alternate supply, however the swap back to normal was unsuccessful. When the alternate breaker was tripped per procedure, the normal breaker indicated closed (green and amber lights extinguish, red light illuminated as expected, but the motor control center (MCC) was not energized. Maintenance has subsequently reenergized the MCC from alternate supply and TSC HVAC is now functional as of 0808 today (September 28, 2006). The total out of service time for the TSC HVAC was approximately 29 hours, 21 minutes.
"A repair plan is being developed to make necessary repairs to the breaker for the normal supply. Once repairs are completed, the breaker will be re-installed so that the MCC can be re-energized from the normal supply. This repair activity will require the TSC HVAC to be removed from service again in order to switch back to the normal power supply. An update will be provided when this evolution is expected to occur.
"This event is reportable per 10CFR50.72(b)(3)(xiii) as described in NUREG-1022 Rev 2 since this work activity affects an emergency response facility for the duration of the evolution."
The licensee will notify the NRC Resident Inspector. The R2DO(Collins) has been notified.
* * * UPDATE ON 9/28/06 AT 15:02 FROM HATCH (DISMUKE) TO ABRAMOVITZ
"On 9/28/06, the HVAC for the Hatch Nuclear Plant's Technical Support Center (TSC) is being removed from service to install the normal supply breaker in the MCC that supplies power to the TSC HVAC following breaker repairs. Estimated time for the TSC HVAC being out of service is 6 -8 hours. An update will be provided when the TSC HVAC is returned to service."
The licensee will notify the NRC Resident Inspector. Notified the R2DO (Collins).
* * * UPDATE 9/29/06 AT 0004 ET FROM HATCH (F. GORLEY) TO M. RIPLEY
"On 09/28/06 at 2329 ET, the HVAC System for the TSC was returned to functional status following the replacement of the normal supply breaker to the MCC and energizing the MCC that supplies the TSC HVAC. Walk-down of the HVAC System for proper operation was completed at 2335 ET."
The licensee will notify the NRC Resident Inspector. Notified the R2DO (Ayres). |
