LOST TRITIUM EXIT SIGN

"The Department [of Public Health for Colorado] received notification from a company that a generally licensed exit sign containing tritium was lost. The company, State Farm Mutual Insurance Company, located in Greeley, Colorado 80638, stated that the sign was discovered missing, in July of 2004. The sign was taken down during a remodeling project in 1996, and was supposedly placed into storage. However, recent attempts to locate the sign have been unsuccessful. A representative from the company stated that they now believe the sign was disposed of at the landfill along with the rest of the construction debris. The sign is a Brandhurst (SRB) Luminexit, Model B100, S/N 552371, that contained about 25 curies of tritium when new (1993). The sign was obtained under the provisions of a general license."

SPILL OF I-131 RESULTING IN CONTAMINATION

On 08/09/04, Cardinal Health reported to the Wisconsin Department of Health and Family Services- Radiation Protection Section that the Cardinal Health Nuclear Pharmacy located in Madison, WI had a spill of approximately 50 milliCuries of an I-131 sodium iodide solution at approximately 0830 CDT on 08/09/04. Under Wisconsin regulations, HFS 157.13(17)(b)(1)(b), the licensee is required to report this within 24 hours. This preliminary report describes what the licensee initially reported. The licensee will provide a formal written report within 30 days as required by subsection (c) of the same section of the regulations.

The spill occurred while transferring a stock bottle from a glovebox to a fume hood. The lead pig containing a vial of 50 milliCuries of I-131 slipped from the individual's hands, hit the floor and spilled some or all of the contents on the floor and adjacent areas. The pharmacy RSO evacuated the area and cleaned the spill to the extent possible. The vial and pig were double bagged and placed in the fume hood. Fixed contamination was covered with lead sheets and general radiation levels are less than 1 mR/hr. A spot on a door in the restricted area reads 10 mR/hr and they are attempting to decontaminate it. Pharmacy staff will pull air samples and will collect thyroid counts on all affected personnel. The pharmacy continues to operate.

The Wisconsin Department of Health and Family Services dispatched a two person radiation survey team to the Cardinal Health Nuclear Pharmacy.

AGREEMENT STATE REPORT - IODINE-125 CONTAINER MISTAKENLY DISPOSED OF AS TRASH

The following information was received via email:

"Approximately 2.5 milliCuries of I-125 was apparently mistakenly disposed to normal trash on 08/05/04. The lost I-125 was received in a single container along with a second container of approximately 2.5 milliCuries of I-125. Normally only one container is received at a time. However, this time two containers were shipped in a single package. The shipping department extracted one of the two containers from the incoming shipping package, and then dumped the remainder of the packing materials to normal trash, apparently including the second container of I-125.

"The loss was discovered 08/09/04 when the radiochemists went to utilize the I-125, and one-half of the shipment was missing. The licensee verified with the shipper that two individual containers were sent in the same package, which also agreed with the activity listed on the shipping papers. The licensee's trash was picked up early morning 08/09/04, and when contacted by the licensee, the trash hauler reported that the trash had already been dumped in a local landfill.

"Radiation levels at one foot from the shielded container were approximately 0.11 millirem/hour based on measurements made of the package that was still onsite. The shielded container holding the lost I-125 was sealed shut, and is not expected to open with normal trash hauling."

AGREEMENT STATE REPORT - LOST/STOLEN MOISTURE DENSITY GAUGE

"A moisture density gauge, model CPN MC-3, containing approximately 8 milliCuries of Cs-137 and 30 milliCuries of Am-241 was lost from the back of a pickup truck while traveling from a jobsite in Carlsbad, CA to the company home office in San Diego. The jobsite was on Cassia Road (Thomas Guide, page 1127, D4-E4). It was reported that the gauge was inadvertently left in the back of the pickup truck without being put into the transportation case, neither the gauge nor the transportation case were secured to the truck, and the truck tailgate was left down. Both the gauge and the transportation case apparently fell out of the truck in the first few miles of travel. The driver noticed the tailgate down shortly after turning onto Palomar Airport Road from El Camino Real (Thomas Guide, page 1127, E2). The driver back tracked and found the case but not the gauge. Local law enforcement authorities were notified, and the RSO went to the scene to assist in attempting to locate the gauge."

* * * UPDATE ON 8/11/04 AT 1900 EDT FROM ROB GREGER TO GERRY WAIG * * *

Mr. Greger reported that the lost gauge was recovered about 1 block from the jobsite today at approximately 1300 PDT. Additional recovery details will be provided tomorrow, 8/12/04.

Notified R4DO (Linda Smith), NMSS (Daniel Gillen), TAS (Aaron Danis), Mexico (CNSNS) by facsimile.

* * * UPDATE ON 8/12/04 AT 1509 EDT FROM ROB GREGER TO GERRY WAIG VIA FACSIMILE* * *

"The gauge was recovered around 1 pm on 8/11/04. It had apparently fallen from the truck a short distance from the construction site. Someone apparently found it and placed it on an adjacent sidewalk. An adjacent business owner (DELETED) noticed the gauge on the sidewalk in front of their business at the end of the day 8/10/04. When the gauge was still there the next morning, they called the phone number of a gauge service company (Mauer Technical Services) listed on a sticker on the gauge, and reported that the gauge was apparently abandoned. Mauer contacted the company that owned the gauge (Christian Wheeler Engineering), who recovered the gauge. When found, the gauge was locked with the source in a shielded position. There was no apparent damage to the gauge.

"California RHB authorities will be pursuing enforcement action with Christian Wheeler Engineering for the loss of the gauge.

"Some details of the loss that were initially reported to California RHB apparently were incorrect. The attached Investigation form has been revised to reflect our current knowledge of this matter." [See Below]

"A moisture density gauge, model CPN MC-3, containing approximately 8 mCi of Cs-137 and 30 mCi of Am-241 was lost from the back of a pickup truck while traveling between jobsites in Carlsbad, CA on 8/10/04. The truck left a jobsite on Cassia Road (Thomas Guide, page 1127, D4-E4) with the gauge. It was reported that the gauge was inadvertently left in the back of the pickup truck without being put into the transportation case, and with the truck tailgate was left down. Within a couple miles of travel, the driver noticed the tailgate down while he was driving on El Camino Real (Thomas Guide, page 1127, E2). The driver back tracked, but could not find the gauge. Local law enforcement authorities were notified, and the RSO went to the scene to assist in attempting to locate the gauge."

AGREEMENT STATE REPORT - WELL LOGGING SOURCE LOST IN WELL DURING TRAINING

The following is taken from a facsimile sent by the Agreement State (Texas)

"Event description: After well logging operations on the afternoon of August 10, 2004, the well logger was removing the source from the tool on the training well. The tool was not fully engaged with the source. When the source cleared the logging tool , the well logger bumped the source into the deflector, causing the source to drop from the handling tool. The deflector performed properly and deflected the source, an 18 curie Am/Be (neutron) source downhole. This is the Atlas No. 2 well, an un-cased hard-rock well located on the Baker Hughes property for training of Baker Hughes staff. The source is a GammaTron Model DA20, Serial No 36313. The source is known to be at the bottom of the 5750 foot well. The training well is currently full of fluid. The operator is going to replace the fluid with clear fluid and begin 'fishing' operations. The wellbore is 8-7/8 inches and this source with nose plug is 9 inches in length."

LOSS OF THE SAFETY PARAMETER DISPLAY SYSTEM (SPDS) FOR GREATER THAN 8 HOURS

"At 08:00 on 8/13/04 Computer Maintenance personnel discovered the Unit 1 SPDS computer was not updating properly. A review into the history identified that the SPDS computer had stopped updating at 21:00 on 8/12/04. The Control Room was notified. The computer group was successful in resetting the SPDS computer and is now properly operating.

"Since the Unit 1 SPDS computer system was unavailable for greater than 8 hours, this is considered a loss of Emergency Assessment Capability and therefore reportable under 10CFR50.72(b)(3)(xiii)."

CONTROL ROOM EMERGENCY ZONE BOUNDARY OUTSIDE DESIGN BASIS

"On 08/13/2004 at 1030 CDT the Kewaunee Shift Manager was notified the control room emergency zone (CREZ) boundary was outside assumed design basis for an unknown amount of time. This is an eight hour non-emergency reportable under 10 CFR 50.72(b)(3)(v)(D), Accident Mitigation.

"On 08/12/2004 at 1915 [CDT], the local operator reported to the control room that he found a control room emergency zone (CREZ) boundary door in the unlatched open position. The local operator immediately ensured the door was secured in the latched closed position. Per Kewaunee's barrier control procedure the Shift Manager requested an evaluation be performed to determine the impact of potential air in leakage on the control room post accident dose consequences.

"On 08/13/2004 at 1030 CDT, the engineering staff reported that based on engineering judgment the unfiltered in leakage that could have entered the CREZ would likely exceed that assumed in the post accident dose analysis. Based on this judgment, the in leakage would have prevented the Control Room Post Accident Recirculation System from mitigating the dose consequences to the control room staff to values less than those determined in accident analysis.

"At the time of discovery the local operator immediately secured the boundary door rendering the CREZ boundary operable. This event has been entered in the Kewaunee corrective action process to investigate the cause of the door being in the open position. No other safety related equipment was out of service at the time of discovery."

RPS ACTUATION DUE TO LOSS OF OFFSITE POWER

"On August 14, 2004, at approximately 1259 hours [EDT], the unit scrammed due to a loss of offsite power. The cause of the loss of power has not been determined at this time. The four emergency diesel generators started as required and properly aligned to the emergency buses. All control rods properly inserted.

"The initial safety significance of this condition is considered to be minimal. All safety systems function properly with the exception of 1 B Standby Gas Train. The 1 B Standby Gas Train tripped due to an overheat condition. Safety significance of this failure is minimal since the 1A Standby Gas Train operated properly and Reactor Building Ventilation System isolated. The plant is in a stable condition.

"Troubleshooting activities are in progress to determine the cause of the event and corrective actions."

Received Group II, VI, and VIII PCIS isolations due to the loss of power. The MSIVs are closed and the licensee manually started RCIC for reactor level control and HPCI for reactor pressure control.

LOSS OF SEVERAL OFFSITE EMERGENCY PREPAREDNESS SIRENS DUE TO ADVERSE WEATHER

"On August 14, 2004, at approximately 1225 hours [EDT], Brunswick began losing the function of several offsite emergency preparedness sirens as a result of adverse weather conditions associated with Hurricane Charley. There are a total of 36 sirens located in Brunswick and New Hanover Counties, NC. The total number of inoperable sirens peaked at 25. As of 1825 hours [EDT], all but 6 sirens located in Brunswick County have been returned to operable status. At present, all inoperabilities have been the result of loss of AC power. The Brunswick County Emergency Operations Center is aware of the condition of the sirens and maintenance activities are in progress to restore the siren capabilities.

LOSS OF SAFETY PARAMETER DISPLAY SYSTEM

At 2045 [EDT] on 08/14/2004, Computer Maintenance personnel discovered the Unit 2 SPDS computer was not updating properly. A review of history identified that the SPDS computer had stopped updating at 1109 [EDT] on 8/14/2004. The Control Room was notified. Computer Maintenance was successful in resetting the SPDS computer at 2100 [EDT], and it is now properly operating.

Since the Unit 2 SPDS computer system was unavailable for greater than 8 hours, this is considered a Loss of Emergency Assessment Capability and reportable under 10CFR50.72(b)(3)(xiii).

The licensee notified the NRC Resident Inspector.

AUTOMATIC REACTOR SCRAM FOLLOWING PARTIAL LOSS OF OFFSITE POWER

"At 0405 on August 15, 2004, River Bend Station had a loss of 230Kv Line #353 (RSS #2, Port Hudson) feeding the plant's switchyard. This resulted in a generator trip and a reactor scram. Feedwater tripped on a Reactor vessel Level 8 signal. RCIC is operating to control reactor vessel level. SRVs were used to manually control pressure. Mechanical vacuum pump (ARC A) would not start to control condenser vacuum. The MSIVs were manually isolated in anticipation of a Group 6 isolation (low vacuum). There was no ECCS initiation. Power was restored to the mechanical vacuum pump ARC B. Vacuum was restored and main steam lanes are in use for pressure control. We are still investigating the root cause.

"The following ESF actuations occurred:

"- Division II Diesel Generator
"- Standby Gas Treatment System
"- Annulus Mixing System
"- Control Building Ventilation System."

The licensee will inform the NRC Resident Inspector.

* * * UPDATE ON 8/15/04 AT 1340 EDT FROM JAMES BOYLE TO GERRY WAIG * * *

"River Bend Station is currently in Mode 3, Hot Shutdown. During the event, offsite power was maintained through Reserve Station Service Line #1 to Division 1 safety related equipment and 'A' balance of plant (BOP) non-safety related equipment. The 230 KV line from the plant's switchyard (RSS Line #2) that was lost during the event has been recovered and the Division 2 bus has been restored to its normal power supply. The Division 2 diesel generator has been secured from operation [and has been placed in standby]

"During, the event, main condenser vacuum was restored from the main control room by starting the 'B' mechanical vacuum pump. Feedwater Pump 'A' remained available during the event. The circulating water supply to the main condenser remained in operation throughout the event. RCIC [Reactor Core Isolation Cooling] remains in service for reactor vessel level control. The ESF [Emergency Safety Feature] systems have been secured and placed in standby. A root cause team has been assembled to address the cause of the initial failure of the 230 KV Line #353."

OFFSITE NOTIFICATION MADE DUE TO INADVERTENT EMERGENCY SIREN ACTUATION


"On August 15, 2004, at approximately 1322 hours, the Brunswick site identified an inadvertent actuation of 1 offsite evacuation siren. There are a total of 36 sirens located in Brunswick and New Hanover Counties, NC. The siren in alarm is located in Brunswick County and was in an alarm condition from 1258 until 1341. In accordance with Brunswick operating procedures, the warning points (Brunswick County, New Hanover County and NC State EOC) have been notified of the inadvertent siren actuation. The remaining 35 sirens are operable.


INITIAL SAFETY SIGNIFICANCE EVALUATION:

"Minimal safety significance. The loss of the single siren will not significantly impact the public notification system. The remaining sirens in both Brunswick and New Hanover Counties have been verified to be operable.

CORRECTIVE ACTIONS:

"The siren was silenced at 13:41 EDT on August 15, 2004. The cause of the inadvertent actuation will be determined and the siren will be repaired.

"The (NRC) resident inspector has been notified."

MANUAL REACTOR SCRAM DUE TO REACTOR FEEDWATER PUMP TRIP

"With a reactor startup in progress at 1303 PDT, operators at Columbia Generating Station inserted a manual
reactor scram when the running Reactor Feedwater (RFW-P-1A) pump tripped. Reactor power was approximately 18% at the time of RFW-P-1A trip. The cause of the RFW-P-1A trip was a high RFW Turbine Drain Tank (MD-TK-1) level; the cause of the MD-TK-1 high level is under investigation. The Reactor Core Isolation Cooling (RCIC) was used [manually started] to maintain reactor vessel water level until reactor pressure was reduced to within the capacity of the condensate booster pumps; the RCIC system has been returned to a standby lineup. The reactor is in mode 3 with both reactor recirculation pumps running at minimum speed (15 Hertz). Decay heat is being rejected to the main condenser via auxiliary steam loads.

"One control rod that indicated full-in immediately after the scram lost full-in indication eleven seconds after the
scram. This control rod indicated full-in again 84 seconds after the scram.

"This ENS notification is made pursuant to 10 CFR 50.72(b)(2)(iv)(B)."
