| Event Text AGREEMENT STATE REPORT - MEDICAL MISADMINISTRATION DUE TO TREATMENT GIVEN TO WRONG PATIENT
The following information was obtained from the state of Texas via email:
"On July 30, 2014, the Agency was notified by the licensee that a patient had received a portion of a treatment intended for a different patient. The licensee's Risk Compliance Officer (RCO) stated two patients had arrived for treatment. Both patients were female of similar size. Both were to receive treatment to the brain, one patient to the right side and the other to the left side. The treatment head frame had been placed on both patients. It was decided that patient two would be treated first. This information was not provided to the individual entering the program into the treatment system so the program for patient one was entered into the treatment system. Patient two was placed on the treatment table and the treatment started. About two minutes into the treatment, a physician reviewing the treatment realized the wrong plan for the patient was being used and halted the treatment.
"The licensee determined the patient received 3.7 gray to 0.5 cc of brain tissue during the treatment. The patient and the patient's physician were notified of the error. The RCO stated the patient's doctor evaluated the event and stated the patient should not experience any adverse effects from the exposure. The patient was later treated using the correct treatment plan.
"The licensee has implemented several corrective actions as a result of the event. They include adding a second time out prior to treatment and requiring multiple staff to identify.
"The device was a Leksell Gamma System Model 24001 containing about 1800 curies of cobalt-60.
"Additional information will be provided as it is received in accordance with SA-300."

| Event Text DAMAGED MOISTURE/DENSITY GAUGE
With the moisture/density gauge still on the ground after performing a standard count, the licensee Radiation Safety Officer backed over the gauge with his pickup truck. The source was not exposed at the time and the source remained shielded. Damage noted to the gauge was a broken shaft that sets the depth of test which is also part of the handle along with some surface scarring to the gauge housing. The gauge was checked with a survey meter for leakage from the sources. At one meter the survey meter reading was less than 0.2 mrem/hr which is comparable to a non-damaged gauge. A leak test wipe was also performed and sent to Humboldt Mfg. for measurement. The gauge was transported and placed in its secure storage location until a determination has been made on how repairs will be accomplished.
The gauge is a Humboldt Model 5001 moisture/density gauge containing 10 mCi Cs-137 and 40 mCi Am-241/Be. |

The following information was received from the State of Texas by facsimile:
"On July 29, 2014, the Agency [Texas Department of State Health Services] was notified by the licensee that a Humboldt Scientific Inc. model 5001 moisture density gauge containing a 10 millicurie Cesium-137 and a 40 millicurie Americium-241 source was damaged at a field site. The technician had placed the device at a sample location and extended the cesium source into the inspection hole. The area had been compacted and the technician did not believe there was any heavy equipment in the area he was working. While waiting for the results of the sample, the technician received an email. The technician needed his glasses to read the email so he walked 70 feet to his truck to get his glasses. While at the truck, the device was run over by a soil compactor (steam roller). The technician went to the gauge and restricted access to the area. He then contacted his Radiation Safety Officer (RSO). The licensee's RSO contacted a service provider (SP) who responded with the RSO to the scene. The device case was severely damaged, but the licensee was able to return the Cesium source to the shielded position and secure it in position. The SP's technician verified the Americium source was still in the device. The SP's technician surveyed the device and did not find any abnormal dose rates. The SP took the damaged device to their facility for disposal. No individual received any significant additional exposure due to this event. Additional information will be provided as it is received in accordance with SA-300."

The following was received via facsimile:
"The licensee reported on July 29, 2014, that a portable density gauge had been damaged by a compaction roller at a temporary job site in Loudoun County, Virginia. The gauge was a CPN Model MC with a 10 millicurie Cesium-137 source and a 50 millicurie Americium-241 source. Investigation by the licensee's radiation safety officer indicated there was no damage to the gauge casing and that the sources were in their shields when the accident occurred. The control rod for the Cesium source was slightly bent as a result of the accident, but both sources remained in their shielded positions. The gauge was returned to the licensee's office and a leak test wipe was sent for analysis. The licensee plans to transport the gauge to an authorized repair facility after the leak test results are received. A written report is required within 30 days."

The following report was received from the California Department of Public Health via email:
"[The licensee reported to the State of California that a] patient [was] receiving Y-90 treatment to the right lobe of liver with Theraspheres. (10CFR35.1000). The prescribed dose was 100-150 Gray, actual dose received was 63.4 Gray. The targeting vessel was 'flowing slowly' causing Theraspheres to 'settle out' prior to reaching target. Preliminary findings suggest that the underdose was due to the physical condition of patient, not through any fault of the medical physicist or licensee.
"No adverse outcomes are expected for the patient. Medical physicist and physicians [are] evaluating whether or not retreatment is necessary."

"At 0925 [CDT] on 08/07/14, a Condition Report was initiated identifying that one of the two air conditioning condenser coil fans for the CPNPP [Comanche Peak Nuclear Power Plant] Emergency Operations Facility (EOF) air conditioner was damaged. With low outside air temperatures, the air conditioner can adequately maintain habitability of the EOF with one of the two air conditioning fans not working. However, outside air temperatures at CPNPP are forecast to reach 100 degrees F later today, and it is believed that the air conditioner will likely trip due to the increased load. With the air conditioner out of service and outside air temperatures near 100 degrees F, the EOF may no longer have the capability for protracted operation under emergency conditions. Compensatory measures are currently in place to staff and activate the Alternate EOF in the event of a declared emergency. Repair of the damaged air conditioning condenser coil fan is scheduled to be completed by the end of the day on 08/08/14.

"During a fire inspection activity involving inspection of fire walls that serve as Appendix R barriers, degradation of some fire walls was identified that was sufficient to prevent these walls from meeting Appendix R requirements as 3-hour fire barriers. In the event of a postulated fire in the affected areas, both safe shutdown paths on the affected unit could be compromised. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).
"Compensatory measures were already in place in accordance with the plant's Fire Hazard Analysis (FHA) as a result of previous conditions involving degraded penetrations in these same fire areas. The presence of the compensatory measures in addition to automatic fire detection in these fire areas ensure that the safe shutdown paths are preserved until the degraded conditions can be corrected.

In addition to automatic fire protection features, the licensee has posted fire watches as a compensatory measure.
The licensee has notified the NRC Resident Inspector. | |
