| Event Text AGREEMENT STATE REPORT - NUCLEAR GAUGES DAMAGED DUE TO FIRE
The following information was provided from the state via email:
"On December 12, 2011, the Agency was notified by a licensee that on Saturday, December 10, 2011, at approximately 1900 CST, there was a fire in the coker unit at their facility in Pasadena, TX. The RSO reported there were 4 fixed nuclear gauges on drums in the area of the fire. The gauges were Ohmart-Vega Model SH1G-1 and each contained a 300 milliCurie Cesium-137 source. Two gauges were directly in the fire and were damaged. The other two gauges were shielded from the fire by the drum they were mounted on and it has not yet been determined if they sustained any damage. The area was barricaded to prevent entry due to unsafe conditions caused by the fire (i.e. structural damage that has to be assessed, heat, ash/hydrocarbons). There were no radiation levels above background found during initial surveys from the barricade line and subsequent surveys conducted under the drums on the ground level and second level (areas where people will begin working). Higher levels will be surveyed prior to entry. The licensee has made arrangements with Ohmart-Vega for service to remove all 4 gauges once the area is safe.
"Gauge and Source Information:
Gauges: All Ohmart-Vega Model SH1G-1
Serial numbers:13543162, 13543163, 13543164 (in fire), 13543165 (in fire)
Sources: Cesium-137, 300 milliCuries each, SN same as gauge
Gauges installed March, 2010.
"More information will be provided as it is obtained."
* * * UPDATE FROM ART TUCKER TO JOHN KNOKE AT1612 EDT ON 06/21/12 * * *
The following information was provided from the state via email:
"On June 13, 2012, the Agency was notified by the licensee that the four gauges involved in the fire on December 12, 2011, had been removed from the vessel and sent to their service provider. Prior to being shipped a source leak test was performed on all four gauges. The results for all the sources was less than the acceptable limit. A second source leak test was performed on the gauges once they were received at the service providers facility. The results were reported as less than the acceptable limit. On June 19, 2012, the service provider contacted the Agency and stated that while repairing one of the gauges containing 300 milliCuries of cesium - 137, their technician, the floor in the work area, and the work bench became contaminated. The area and the technician were decontaminated to background that same day. The service provider has not provided the contamination levels, but stated that they were low enough that they did not believe there was any risk to the worker of internal contamination. They also reported that the gauge was void of lead shielding. The service provider is trying to determine how the source failed.
Additional information will be provided as it is received in accordance with SA 300."

| This material event contains a "Category 2" level of radioactive material. | Event Text AGREEMENT STATE REPORT - CAMERA SOURCE FAILS TO RETRACT
The agreement State of California reported the following via email:
"On 06/13/12, the RSO at Team Industrial contacted RHB to report a radiography camera incident that occurred on 05/22/12 at the Evergreen refinery in Newalk, CA. The radiographers were using a QSA 880 camera on the second deck of the unit 1 at this refinery. The radiographer cranked the 59 Ci source out into the collimator and after the exposure, he couldn't retrieve the source back into the shielded position. He immediately contacted the RSO. Per RSO's instructions, the radiographer unscrewed the crank assembly and pulled the cable back to retrieve the source into shielded position. There were no exposures to the radiographers, two assistants, and any member of the public. The licensee's Instadose dosimetry indicated 8 mR for the radiographer for the period of 5/18 - 5/22 and 7 mR and 0 mR for the two assistants for the same period. Their pocket dosimeters indicated zero exposure for all three individuals.
"The crank assembly was sent to QSA and they have indicted that the worn out teeth and bearings of the crank assembly inhibited the normal retrieval of the source.
"RSO will be providing a detailed report to RHB ASAP."
CA 5010 Number: 061312
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

| Event Text POSSIBLE PERSONNEL OVEREXPOSURE GREATER THAN 25 REM
The RSO from the licensee's corporate headquarters called to report a possible overexposure of a radiographer working on the North Slope of Alaska. Landauer reported that for the month of May, an individual's badge read 144 Rem.
* * * UPDATE FROM GAYLE STATON TO JOHN KNOKE AT 1530 EDT ON 06/21/12 * * *
The following information was received from the licensee via email:
"On June 20, 2012, Acuren USA reported a possible radiation overexposure of 145R to an individual working for our [Acuren USA] company under NRC License # 42-32443-01. After interviewing all individuals involved, and conducting an internal investigation, we [licensee] believe that this dose was not received by the individual. In addition, the crew did not work with a gamma source but rather with x-ray tubes the entire month. The individual in question worked reading the scanner inside of a vehicle rather than outside utilizing the x-ray tube. He was never around the radiation producing equipment while it was energized. It is apparent that this dose was not received by this person. Therefore Acuren USA respectfully requests the NRC rescind Event Notification 48040. We apologize for the inconvenience and appreciate all your help with this matter."

"This ENS is being issued in advance of a planned maintenance activity.
"Today 6/21/12, the Technical Support Center (TSC) ventilation system will be removed from service to perform corrective maintenance on a ventilation damper. The emergency ventilation system will not be available and cannot be restored within the time period required to staff and activate the Emergency Response Organization (ERO). The work will complete today 6/21/12.
"If an emergency is declared and the TSC activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological or other conditions. The Station Emergency Director would assess habitability in accordance with station procedures. TSC relocation of personnel would be directed as required until such time that the TSC ventilation system is returned to service."
The licensee notified the NRC Resident Inspector.

"Certain 710DU Trip Units may not perform their intended safety function as a result of certain wire wound precision resistors experiencing a degradation of reliability. Additionally, certain 710DU Readout Assemblies used to calibrate 710DU Trip Units may experience degraded digital display accuracy during calibration due to a similar cause. Rosemount Nuclear Instruments, Inc. does not have complete information relating to specific plant applications and therefore cannot determine the potential effects of the condition on plant operation.
"This notification affects certain Model 710DU Trip Units and certain 710DU Readout Assemblies shipped from Rosemount Nuclear Instruments, Inc between March 16, 2005 and May 10, 2012."
