The following information was obtained by the licensee via facsimile:
"Reactor SCRAM received at 0924 [hrs] PDT. Initial indications are the scram signal was caused by RPS [Reactor Protection System] High Pressure. Following the scram, 2 [two] control rods did not immediately indicate [fully inserted]. Control room staff entered [procedure] PPM5.1.2 and took the required actions. All control rods subsequently indicated [fully inserted].
"An ALERT Classification was declared at 1000 [hrs] based on PPM 13.1.1 Criteria 2.2.A.1, 'RPS Setpoint exceeded and automatic actions failed to result in a rod pattern which alone assures reactor shutdown'. Manual actions resulted in all rods [fully inserted] and reactor power [less than or equal to] 5 percent.
"All other plant systems responded as expected with the exception of a wetwell-to-drywell vacuum breaker which indicates open. Investigation into the cause of the scram and actual control rod position is ongoing. Further details will be provided when available."
The licensee also reports that no relief valves lifted during the transient. Decay heat removal is via the main condenser. Reactor level is steady at 36 inches. Reactor temperature and pressure are 507 degrees and 710 psig respectively. Offsite power is available. All emergency systems are available in standby.
The licensee has notified the NRC Resident Inspector of the incidents. The NRC entered Monitoring mode at 1327 hrs EDT with Region IV leading. The NRC exited Monitoring at 1530 hrs. EDT and returned to Normal mode.
Notified HHS (Ayles) as well as others noted in notification block.
* * * UPDATE AT 2130 HRS EDT ON 7/30/04 FROM COLEMAN TO CROUCH * * *
"At 1358 [hrs.] EDT on 7/30/04, NRC was notified of an Alert at Columbia Generating Station (EN #40910).
"This is a follow-up to inform NRC that the event was terminated at 1457 [hrs] (EDT) (1157 PDT). All control rods are inserted. Reactor is shutdown and water level is normal. All required emergency systems are operable. All offsite and onsite power sources are operable. Reactor pressure is normal."
The licensee has notified the NRC Resident Inspector, State of Washington and local authorities of the termination.
The NRC Operations Center notified R4DO(Bywater), DHS, FEMA, DOE(NRC), USDA, EPA and CDC(HHS).
* * * UPDATE AT 1930 EDT ON 08/03/04 FROM M. HEDGES TO A. COSTA * * *
"At 1358 EDT on July 30, 2004, NRC was notified of an Alert at Columbia Generating Station (EN #40910). A subsequent notification was made to inform the NRC that the event was terminated at 1157 PDT (1457 EDT) on July 30, 2004.
"This is a follow-up to inform the NRC that Columbia Generating Station is retracting its Alert Emergency Declaration due to the following reason. Following the RPS actuation, control rod position indication for two control rods was indeterminate for approximately two minutes to the control room staff. A subsequent review of control rod position indication from the Plant Data Information System (PDIS), Rod Worth Minimizer (RWM) logs, and Auto Scram Timer (AST) data by Columbia Generating Station personnel shows that all rods were successfully inserted to the 'Full-in' position following the initial RPS actuation, assuring that the reactor was shutdown under all conditions. The Emergency Action Level for this Alert classification requires that the following three conditions be met: Any RPS set point (including manual) has been exceeded per T.S. 3.3.1.1 AND RPS actuation failed to result in a control rod pattern which alone always assures reactor shutdown under all conditions AND Manual actions (mode switch in shutdown, manual push buttons, and ARI) result in reactor power LE 5%.
"Since all rods were successfully inserted without the assistance of any manual actions and within the Technical Specification required time, Columbia Generating Station staff now believes that no emergency classification should have been made, and we are retracting the Alert emergency classification from this event notification.
The problem with control rod position indication following the scram is being addressed through our corrective action program."
The licensee notified the NRC Resident Inspector and will notify local, State, and other Government Agencies of this update.

"Salem Unit 1 experienced an underground fuel leak that required notification to the state of N.J. (NJDEP). Fuel oil was observed in a storm drain, there was not a release to the Delaware river and the storm drain system has been isolated and pumped out. The source of the leak is under investigation. There were no injuries as a result of the spill and no equipment has been declared inoperable. The bulk fuel oil storage tank has been isolated as a potential leak source." Lower Alloways Creek Township will be notified.
The Bulk fuel oil storage tank makes up to Salem Unit 1 & 2 diesel storage tanks which are at full capacity. Licensee is making a contingency plan that they will not be able to use the bulk fuel oil tank and they plan to have fuel oil tank trucks come onsite Tuesday.
The NRC Resident Inspector has been notified. |

| Event Text POTENTIAL PERSONNEL OVEREXPOSURE
Dr. Roy Parker, a consultant for High Mountain Inspections (a radiographer) in Casper, WY reported that Landauer, their film badge processor, informed the licensee that an employee's June badge had a deep dose reading of 121,662 milliRem when read. Landauer also stated that the badge reading was repeated with the same results. The badge was imaged to determine whether the dose was static or dynamic but the results were inconclusive.
Dr. Parker also reported that 1) the employee does not exhibit any symptoms of overexposure, 2) the employee is a manager and was in the field for only 3 days in June and was not present during any abnormal occurrences, and 3) co-workers that were in the field with the employee did not have any abnormal results when their badges were processed.
As a precaution, the employee will undergo appropriate blood tests to confirm/deny the reading results.
Dr. Parker notified R4 Materials (Cain). |

"Maintenance technicians were performing surveillance testing on the Division 3 Battery. The as-found bus voltage was approximately 139 VDC and the technicians adjusted the battery charger output voltage to 134 VDC.
"At 1046, the control room received an alarm with bus voltage at 125 VDC. The High Pressure Core Spray System was declared inoperable per Technical Specification 3.8.4 with Division 3 DC Bus voltage < 130 VDC.
"The maintenance technicians determined that the voltmeter used to measure the voltage was defective and actual bus voltage was adjusted to 125 VDC.
"At 1105, Division 3 bus voltage was restored above 130 VDC (136 VDC) and the High Pressure Core Spray System was declared operable. The High Pressure Core Spray System was inoperable for approximately 19 minutes from when the alarm was received until the maintenance technicians restored voltage to 136 VDC. The High Pressure Core Spray System is a single train system."
