AGREEMENT STATE REPORT FROM OHIO: CONTAMINATION INCIDENT IN SOURCE HANDLING FACILITIES
Agreements State report received via e-mail
Event Cause: Inadequate Procedure
"The Bureau was notified at approximately 4:00 PM on Friday, 10/20/06 that the licensee experienced a contamination incident in their source handling facilities. The licensee stated that a 10 mCi Cesium-137 source had been breached during source disposal operations. The source was breached when a source holder was being cut or drilled to remove the source. Contamination was detected on the individual conducting the source removal operations, throughout the source storage room, and outside in the source handling area. Note that these are all controlled access/restricted areas within the facility. The contamination on the individual was located on the clothing, hair, arms and hands. The individual underwent onsite decontamination and was sent to a local hospital as a precautionary measure. As of today (10/23/06) there is still some residual contamination on the individual's finger tips; however, further scrubbing to remove this contamination may cause breakdown to the skin in that area. The individual is currently wearing gloves in an attempt to sweat out the residual cesium contamination. The individual is scheduled for a whole body scan on Wednesday, 10/25/06. The source handling area was secured and closed to all personnel over the weekend. A decontamination contractor has been retained by the licensee to arrive on site on Monday, 10/23/06. A Bureau of Radiation Protection inspector will arrive on site on Wednesday, 10/25/06 to assess the contractor's decontamination efforts and to further investigate the circumstances that caused the contamination event. This information is current as of 10:00 AM on Monday, 10/23/06."
"Corrective Actions: Not Reported
Contamination to person: 0.010 Curies, 0.37 GBq of Cs-137 (Personnel Contamination)
Surface Contamination: 0.01 curies, 0.37 GBq of Cs-137 (Temporary Rad. Controls)

* * * UPDATE FROM OHIO DEPARTMENT OF HEALTH (MICHAEL SNEE) TO JOE O'HARA ON 10/25/06 AT 1036 EDT VIA E-MAIL * * *
"Two separate Cs-137 sources were involved in the incident. Both were in TN model 5178/5178A source holders. The licensee's employee could not open the holders to remove the sources for disposal. The employee misunderstood where the sources were located in the holders and cut one holder (containing a 11 mCi source) with a bandsaw while drilling into the other holder (containing a 26 mCi source). The saw cut into the source and the drill bit broke and stuck in the source capsule. The contamination was contained to the secure source handling area. A contractor is on site to perform the facility decontamination."

AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
The NRC Operations Center received the following information from the State of Colorado via fax:
"The Radiation Management Program of the Colorado Department of Public Health and Environment received telephone notification on Monday 23 October 06 regarding the theft of a portable moisture density gauge.
"Radioactive Materials Involved: a Troxler 3430 gauge, serial number 28201 containing 333 MBq (9 mCi) of Cesium 137 and 1.63 GBq (44 mCi) of Am-241/Be.
"Event details: The theft occurred at the residence of an employee of the licensee ( DELETED) at 6:15 PM on Sunday 22 Oct 06. The Troxler gauge was reported to be in a locked case, chained and locked in the bed of a Ford Ranger. The employee witnessed the theft of the truck from his garage with the gauge secured in the bed of the truck.
"The local police were called at the time of the theft but (DELETED) did not have a police contact name or phone number at the time of this report."
Notification was made by licensee RSO to the State of Colorado.
CO Incident Number 42928.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. |

MANUAL REACTOR TRIP AFTER A 100% LOAD REJECTION
"On October 25, 2006, at approximately 0247 hours (EDT), Main Control Room operators observed indications of a 100% load rejection and manually tripped the reactor at 0248 hours (EDT). During the event, Main Control Room operators received an alarm indicating that one or both pressurizer PORVs lifted briefly. The PORV(s) reclosed as designed. The reactor is currently stable in Mode 3.
"During the event, the steam generator PORVs briefly opened and re-closed, as expected. All controls rods indicated fully inserted following the reactor trip. The normal post-trip electrical lineup is providing power to the plant and the electrical system is stable at this time. Decay heat is currently being removed by use of the normal feedwater system and the condenser steam dumps.
"The cause of this event is under investigation. Follow-up notifications will be provided if important new information is obtained or plant conditions significantly change."
The licensee reported no steam generator tube leakage i.e. no radionuclide release during the brief lifting of the steam generator PORVs.
The licensee notified the NRC Resident Inspector.
* * * UPDATE ON 10/25/2006 AT 0941 FROM G. SANDERS TO M. ABRAMOVITZ * * *
"Subsequent to the initial notification, it has been determined that the automatic initiation of the Auxiliary Feedwater (AFW) System is also reportable under 10 CFR 50.72(b)(3)(iv)(A), Specified System Actuation. The AFW System automatically actuated as expected during the event in response to the secondary plant transient."
The licensee notified the NRC Resident Inspector.

THREE SEALED TRITIUM SOURCES MISSING FROM INVENTORY
The National Institute for Occupational Safety and Health (NIOSH) in Cincinnati, OH reported that three electron capture devices with a total activity of 658 milliCuries of tritium are missing. The devices were last physically verified in inventory in October 1996. The devices were removed from the inventory listing in 1997 and no paperwork related to their disposition can be located. The institute contacted the device manufacturer, excess property listings, past RSO's, past device users, and other universities and institutions with negative results. The devices are now considered lost.
The following two sources were in the same Baseline Model 1030A Gas Chromatograph (serial # 232):
Valco Industries Model 140 electron capture detector (serial # 158). The initial activity was 1000 mCi. Current activity is approximately 387 mCi.
Valco Industries Model 140 electron capture detector (serial # 124) . The initial activity was 1000 mCi. Current activity is approximately 218 mCi.
The third source was a Scentex electron capture detector in a Scentor Model Gas Chromatograph (serial # 40K191). Initial activity was 150 mCi. Current activity is approximately 53 mCi. The serial number of the detector is not known.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. |
