Event sent to NRC Headquarters Operation Center via e-mail.
"ABSTRACT: (where, when, how, why; cause, contributing factors, corrective actions, consequences, Dept. of Health (DOH) on-site investigation; media attention):
"At 6:30 am, 4 October, the Spokane FedEx Terminal Manager discovered a flattened lead cap. A partial label on the cap indicated it came from one of two packages containing IsoRay, Cesium 131, therapy seeds. A second package was found crushed but essentially intact; the seeds in this package were all present and apparently undamaged. Scraps from the first box were found on the runway and other pieces on the floor of a tug (airport vehicle used to move cargo). It is thought the damage was caused when the boxes were caught between moving pieces of the cargo loading equipment. The actual incident appears to have happened 12 hours earlier (about 6 pm, 3 October). Dayshift FedEx staff had apparently placed the damaged packages on the floor on the passenger side of the tug cab.
"Four WA Department of Health, Health Physicists responded to the scene at about 8:00 am, 4 October. IsoRay also dispatched a team of three HP technicians arriving at noon with equipment including a decontamination kit. WA Department of Health staff were able to retrieved three of the sixty-three seeds that were in the one shredded package. Several areas of contamination were also found.
"Measurement on the floor of the tug's passenger side was reading 150 Mr/hour with an Eberline RO2 ion chamber. Radiation measurements on the crushed pig lid were about 25 Mr/hour with an RO2 and a contamination measurement of about 400 cpm with a GM instrument. Contamination reading on the crushed box was about 300 cpm with the GM instrument. A spot on the tarmac was found reading about 12 Mr/hour with an RO2.
"The undamaged stainless steel pig reads about 5 Mr/hour with an RO2.
"Night shift personnel were asked to return to the facility. No personnel contamination had been found at the writing of this report.
"WA Dept of Health and IsoRay staff continue to look for the remainder of the packaging and seeds.
"No news media attention yet.

"Date of Event: 3 October 2006 (reported 4 October 06).
Location of Event: Spokane International Airport, FedEx Terminal, Spokane Washington.
"ABSTRACT: (where, when, how, why; cause, contributing factors, corrective actions, consequences, Dept. of Health (DOH) on-site investigation; media attention):
"At 6:30 am, 4 October, the Spokane FedEx Terminal Manager discovered a flattened lead cap in the plane loading area. A partial label on the cap indicated it came from one of two packages containing IsoRay, Cesium 131, cancer therapy seeds. A second package was found crushed but essentially intact; the seeds in this package were all present and found to be undamaged. Scraps from the first box were found on the runway and other pieces on the passenger side floor of a 'tug' (airport vehicle used to move cargo containers). It is thought the damage was caused when the boxes were caught between moving pieces of the cargo loading equipment. The actual incident appears to have happened 12 hours earlier (about 6 pm, 3 October 06). Dayshift FedEx staff had apparently placed the damaged packages on the floor on the passenger side of the 'tug' cab but this was unable to be verified.
"Four WA Department of Health, Health Physicists responded to the scene at about 8:00 am, 4 October. IsoRay also dispatched a team of three HP technicians arriving at noon with equipment including a decontamination kit. WA Department of Health staff returned Thursday, Friday and Monday to continue the investigation. WA DOH was not able to find any additional material except that found October 4. These finds amounted to three seeds and a minor amount of contamination in the tug and on the loading surface. WA DOH spent 16 FTE days looking for the material and interviewing FedEx staff. Night shift personnel were asked to return to the facility. No personnel contamination was found. All parts of the complex within the FedEx secured area (buildings and property) and public areas adjacent to the FedEx secured property were searched.
"IsoRay personnel decontaminated the tug and loading surface. Took control of the three recovered seeds found in the tug and took all of the damaged packaging including the second package (damaged but intact) and its contents.
"Measurement on the floor of the 'tug's' passenger side was reading 150 mR/hour with an Eberline RO2 ion chamber. Radiation measurements on the crushed pig lid were about 25 mR/hour with an RO2 and a contamination measurement of about 400 cpm with a GM instrument. Contamination reading on the crushed box was about 300 cpm with the GM instrument. A spot on the tarmac was found reading about 12 mR/hour with an RO2.
"The outside of the undamaged stainless steel pig measurers about 5 mR/hour with an RO2. Some product is transported in a lead container and some in stainless steel. The missing material was in lead; the material in the damaged second package was in stainless steel.
"WA Dept of Health and IsoRay staff were on site for a total of 4 days. WA DOH spent approximately 16 FTE days looking for the remainder of the packaging and material. Nothing additional was able to be located.
"There was a local television media news story.
"Notification Reporting Criteria: 10 CFR 30.50(b)(1)
"Isotope and Activity involved: 330 mCi, 12.2 Gigabecqerals of Cesium 131. Cesium 131 has about a 9.2 day half-life.
"Overexposures? (number of workers/members of the public; dose estimate; body part receiving dose; consequence): The investigation indicates it unlikely that personnel received any significant radiation exposure. However, this could not be substantiated since facility individuals were not forthcoming with information that could be used to make an exposure determination.
"Lost, Stolen or Damaged? (mfg., model, serial number): 3 of 63 missing seeds recovered, contamination found in tug, packaging and on the runway. The remainder of the material was not able to be located.
"Sealed Source and Device Registry: WA-1220-S-101-S
"Disposition/recovery: WA DOH has indicated to FedEx management that hazardous materials transportation handling procedures should be revised and staff refresher training should be performed.
"Leak test? The seeds are leak tested prior to packaging and were within limits. Seeds from the damaged second package were found to be undamaged.
"Vehicle: (description; placards; Shipper; package type; Pkg. ID number) Airport tug, N/N FedEx air bill # 730 235 322 954.
"Release of activity? Three seeds found in the tug. Contamination found in the tug, on packaging and on the loading runway.

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. |

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."

"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."

The State provided the following information via e-mail:
"At 2:30 a.m. a Smith Emery employee was taking backscatter measurements on Highway 99 North in Stockton, California just south of the Fremont off ramp. One lane was restricted to traffic while the Smith Emery employee took backscatter measurements to determine asphalt density. Shortly thereafter a semi-tractor and trailer crossed the barriers into the restricted lane and ran over the CPN MC3 gauge (#m37107963). The gauge outer case was destroyed and the source rod was broken off and carried away from the gauge down the road. The source rod contained 10 mCi of cesium 137. The 50 mCi americium source remained affixed to the portion of the gauge case that was intact. The licensee quickly notified the California Department of Emergency Services, who notified the Radiological Health Branch. Following the incident, the licensee restricted access to the area where the gauge was ran over and awaited the RSO to arrive. The RSO arrived around 6:30 am and with assistance from the Stockton FD, determined the gauge sources were intact and placed them in their transport case to transport to CPN, the gauge manufacturer. CPN leak tested the sources and their was no leakage or contamination found.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text 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.

"On 10/23/06 at approximately 1050 hours, during a routine area walk-down of Dry Conversion Facility (DCF) 4th level an operator noticed the pungent/repulsive smell of hydrogen fluoride (HF) vapor near the L-3 UF6 to UO2 conversion vessel and back-up filter vessels. [Note: The odor threshold for HF is approximately 0.042 ppm.] He immediately exited the area, placed it on respiratory protection required status and then notified a Health and Safety Technician (HST).
"The operator donned respiratory protection equipment and 'Dragered' the suspect area for HF vapor and the results were positive. The HST also pulled samples for airborne radioactivity and none were observed. The operator notified the DCF control room and shutdown of the affected was initiated.
"This report is being made because it has the potential for meeting the following two 10 CFR 70 Appendix A, 24 hour reporting Criteria.
"1. Any event or condition that results in the facility being in a state that was not analyzed, was improperly analyzed, or is different from that analyzed in the ISA and which results in an accident sequence with high consequence that is not at least highly unlikely, or an accident sequence with intermediate consequence that is not at least unlikely.
"The location of the HF leak was in a Dry Conversion UF6 to UO2 conversion vessel. This major component is in the powder production process system. However, the boundary of UF6 Vaporization process system ends at the conversion vessel inlet. Accident sequence 810-5 for UF6 Vaporization process system, as reported in the ISA Summary, clearly bounds the conditions associated with this event. The protections listed in this accident sequence are also applicable to this event. However, this condition is not specifically covered in the accident evaluation of the powder production process system. Because this condition was not specifically evaluated in the powder production process system accident evaluation, it is not clear that this reportability criterion does not apply.
"3. An acute chemical exposure to an individual from licensed material or hazardous chemicals produced from licensed material that could:
a. Lead to irreversible or other serious, long lasting health effects to a worker
b. Cause mild transient health effects to any Individual located outside of the controlled area.
"Based on the low odor detection threshold for HF and the operator's response to immediately leave the area until protective equipment had been donned, the subsequent measured HF concentrations, estimated exposure time and the physical evidence of the individual exposed to HF, long lasting serious health effects are not expected.
"All other conversion units were shut down at approximately 1300 on 10/26/2006 to further evaluate the other unit's conditions although no leakage of HF or radioactivity has occurred." |

The licensee was performing load reject testing on the Unit 2 turbine generator when oscillations were observed on the plant steam dump system. These oscillations caused a high steam generator water level that caused both Main Feed Pumps (MFP) to trip . Upon receiving this indication the licensee manually tripped the reactor. All Auxiliary Feed Water (AFW) pumps started as expected.
All rods inserted as expected. Decay heat is being removed using AFW supplying both steam generators and steaming to the steam dumps. The plant is in a normal shutdown electrical lineup.
