| Event Text MARYLAND AGREEMENT STATE REPORT - UNABLE TO RETRACT RADIOGRAPHY SOURCE
The following information was obtained from the State of Maryland via email:
"At 12:17 PM on December 16, 2013, the Radiation Safety Officer of Maryland Q.C. Laboratories, called [the State of Maryland] to report an incident that occurred today in their radiography vault. She reported that they were performing industrial radiography using a 34.7 Ci Ir-192 source, QSA model A424-9 in a model 880 D camera, when a steel pipe fell on the guide tube preventing the source from retracting into the shielded position. She stated that attempts to retract the source were not successful. She further stated that QSA Global will arrive at the licensed facility tomorrow to recover the source. The source is in a tungsten collimator inside the vault. The assistant radiographer reported 10 mRem on his SRD. For security, Maryland Q.C. locked the door to the vault and will post a 2-man crew at the facility until QSA arrives. Maryland Health Physicist Bob Nelson is on site at this time conducting an investigation. He reports that the dose rates outside the vault are less than 1.0 mRem per hour."

"The Maryland Health Physicists conducting the investigation at Maryland QC Laboratories reported on 12/17/2013 at 0930 hours that the source has been safely retrieved and stored in the camera."

| Event Text AGREEMENT STATE REPORT - STUCK RADIOGRAPHY SOURCE
The following was received via facsimile:
"Event Narrative: While performing radiography operations at Microsoft Bld. 32 in Redmond, Washington, the radiography source could not be retracted from the collimator back into camera. The Radiation Safety Officer (RSO) of Mistras then called the Washington State Department of Health (DOH) emergency line (206 Nuclear) and an inspector was dispatched to the scene. At the scene was the RSO, Assistant RSO (trained in source recovery), assistant radiographer, and another radiographer. Assistance was being provided via telephone by QSA Global. It is not known yet if previous attempts brought the source through the camera and into the crank cable tube. However, while attempting to remedy the situation the (0-200 mR) pocket dosimeter of the radiographer had gone off scale. The radiographer was removed from the scene and his TLD has been sent in via overnight mail for emergency processing. The collimator was attached to the camera with a 2-3 inch long fitting (there was no guide tube). After disconnecting the crank cable from the camera, the crank cable was pulled back to the crank (while observing survey meters), and it was discovered that the connector at the end of the cable where it was attached to the pig tail was broken. The camera and collimator were loaded onto a dry wall cart and covered with several bags of lead shot. A moving 2 mR/hr barrier was established around the cart during this movement. The apparatus was then moved to a remote area of the parking lot. Once in the parking lot, 2 mR/hr barricades were set up. Eight foot long tools were made in order to unscrew the fitting from the collimator. Once the fitting was removed, the connector end of the pigtail was exposed and could be pulled out (with eight foot grappler) of the collimator and inserted into another camera. This procedure was practiced several times with a dummy source prior to the actual transfer. The highest dose received on the retrieval team was 93 mR. An investigation is about to begin, and Mistras was performing reenactments earlier today. More information pending."
* * * UPDATE ON 12/19/13 AT 1439 EST FROM STEPHEN MATTHEWS TO DONG PARK * * *
The retrieval team leader received 43 mR with pocket dosimeter, the licensee RSO received 93 mR with pocket dosimeter, the assistant radiographer received 85 mR with pocket dosimeter, and the radiographer received 40 mR with pocket dosimeter.

"At 0828 EST on 12/23/2013, the North Anna control room was notified that the Virginia State Emergency Operations Center (EOC) had lost all power and all offsite communications. This included commercial phone lines, automatic ring downs, and the State ring down loop (lnsta-phone). At 0900 EST, all communications were restored once emergency generators were placed in service at Virginia State EOC. The Virginia State EOC initially lost offsite power only but all communications were supplied power by an Uninterruptable Power Supply (UPS). Subsequently, the UPS batteries depleted and all communications were lost. At that time (0828 EST) Virginia State EOC personnel notified the North Anna control room and supplied individual cellular phone numbers as an alternative method of contacting the Virginia State EOC.
"This report is reportable in accordance with 10CFR50.72(b)(3)(xiii), any event that results in a major loss of offsite communications capability, (e.g. Emergency Notification System)."

"At 1930 EST on June 7, 2012, it was determined that a series of gaps in a high energy line break (HELB) barrier rendered equipment in the west 480 VAC switchgear room inoperable. There is evidence that this condition had existed since initial construction. The openings were sealed and the equipment restored to operable status at 1605 EST on June 8, 2012. This condition was previously reported to the NRC pursuant to 10 CFR 50.73(a)(2)(i)(B) in LER 2012-001-00. Upon further engineering analysis, it was determined that for limited exposure times safety functions could have been prevented for certain postulated high energy line breaks. Therefore, this condition is also being reported pursuant to 10 CFR 50.73(a)(2)(v)(A),(D), and 10 CFR 50.72(b)(3)(v). The NRC Senior Resident Inspector has been notified." | |
