| Event Text AGREEMENT STATE REPORT - STUCK RADIOGRAPHY SOURCE
The following was received via email from the State of Arkansas:
"The following are the findings of the Arkansas Department of Health, Radioactive Materials Program, concerning Event Number [AR] 07-10-01 involving at stuck radiography source in Wilburn, Arkansas at a pipeline location. The Department was contacted on July 26, 2010 stating that the incident occurred around 9:30 a.m. on the first shot. The camera involved was an Industrial Nuclear IR-100 (Serial Number 6961) that contained a 34 Curie Iridium-192 source (Model G-40T, Serial Number RC3103). SPEC had been contacted and was expected to arrive at the location around 5:00 a.m. on July 27, 2010. In the meantime, the crew and both of the Assistant Radiation Safety Officers maintained constant surveillance.
"Health Physicists from the Arkansas Department of Health also went to the incident location. When arriving, it was discovered that the source was in an approximately 10 foot hole and it was indicated that the radiography crew had performed three cranks and then the source would not retract back into the shielded position. SPEC successfully retrieved the source. The source, camera and associated equipment are being transported to the SPEC facility in Louisiana for evaluation.
"It appears that this incident may have been caused by the failure of the locking mechanism of the camera. The licensee and SPEC [are] to supply the Department with a written report.
"The Department will provide updates as information is received."
This is Arkansas Department of Health, Radioactive Materials Program event number 07-10-01. |

The following report was received via fax from the State of Massachusetts:
"Licensee RSO, called to report that he received notification from the Corporate Office that a Landaur exposure report indicates one of his radiographer's whole body badge read in excess of 17,000 mrem for June of 2010. This person performs radiography operations using the x-ray vault. [The RSO] does not feel that the exposure is real, however, he is initiating an investigation. He stated it's more likely that the WB badge was left in the radiography vault inadvertently." |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text OKLAHOMA AGREEMENT STATE REPORT - IRRETRIEVABLE WELL LOGGING SOURCE
The following information was obtained from the State of Oklahoma via email:
"A well logging source has been lost down hole in Woods County, OK. The source information is Cesium 137, 1.78 Curie, S/N A3128, QSA Global model Y3. The licensee is Thrubit, Oklahoma license OK-32115-01.
"The source is at a depth of 4452 [ft.] according to the gamma ray log. Surface location is Section 13-28N 13W, Lat 36.899418, Long -98.555695.
"The well operator is Chesapeake."
"The licensee has monitored to verify that there is no leakage of radioactivity from a source rupture. Four unsuccessful fishing attempts have been made and the licensee believes that the source is lodged in rubble where it can't be retrieved. The licensee informs DEQ [Oklahoma Dept. of Environmental Quality] they expect to submit a request to abandon the source. The Cesium source is lost as mentioned, but no AmBe or Californium source is lost.
"The above is based on telephonic information received from the licensee and is a preliminary report. This information may be modified or updated based on written reports from the licensee or a DEQ investigation."
It is unclear at this time when the source was lost.
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
Although IAEA categorization of this event is typically based on device type, the staff has been made aware of the actual activity of the source, and after calculation determines that it is a Less than Cat 3 event.
Note: the value assigned by device type "Category 3" is different than the calculated value "Less than Cat 3" |

"On July 30, 2010, at approximately 0720 Mountain Standard Time (MST), the Palo Verde Emergency Planning Department discovered that public warning system siren No. 17 was not responding, and therefore, is out of service. The loss of siren No. 17 could potentially impact a population of approximately 1196 people in the 5-mile emergency planning zone (EPZ).
"Since the loss of siren No. 17 could impair Arizona Public Service Company's ability to inform greater than 5% of the population within the EPZ, this notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii). If an event occurs while siren No. 17 is out of service, the Palo Verde Emergency Plan has a contingency for dispatching Maricopa County Sheriff's Office (MCSO) vehicles with loud speakers to alert persons within the affected area. The MCSO is prepared to implement this contingency should it become necessary.
"Troubleshooting to determine the cause of the failure has commenced."
The NRC Resident Inspector has been notified. | |
