AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
The following report was received from the Alabama Department of Public Health via facsimile:
"On July 19, 2011, [the] Radiation Safety Officer for Building and Earth Sciences of Birmingham, Alabama notified the Alabama Office of Radiation Control that their 2004 Toyota Tacoma truck with a Troxler model 3430 moisture density gauge was stolen at the Kroger's Grocery Store parking lot at 300 North Dean Road in Auburn, Alabama. Building and Earth Sciences is authorized to possess and use radioactive material under their Alabama Radioactive Material License No. 1266. The Auburn Police Department was advised of the incident. The stolen gauge was identified as a Troxler model 3430, serial number 22300, with 0.3 gigabecquerels of Cs-137 and 1.48 gigabecquerels of Am-241:Be. [The RSO] indicated that the gauge transport case was properly secured within the bed of the pickup.
"As of July, 27, 2011, 11:00 AM CDT, the truck and the device containing radioactive material remain missing. This is all the information that this Agency [Alabama DPH] has at this time."
Alabama Event 11-28
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.

LOSS OF BOTH TRAINS OF EMERGENCY RESPONSE DATA SYSTEM DUE TO LOSS OF PLANT PROCESS COMPUTERS
"At 2059 [hrs. EDT] on 7/27/11, St. Lucie Unit 1 lost both the 'A' and 'B' computer trains associated with Emergency Response Data Acquisition and Display System (ERDADS). Attempts to restore either train have been unsuccessful. The cause of the failure is not known and continues to be investigated.
"This is reportable in accordance with 10CFR 50.72(b)(3)(xiii) due to a major loss of emergency assessment capability for greater than one hour."
The loss of the plant process computers also resulted in the loss of the Safety Parameter Display System. Redundant indicators are available to operators.
The licensee has notified the NRC Resident Inspector.
* * * UPDATE ON 8/1/2011 @1140 EDT FROM JOE HESSLING TO MARK ABRAMOVITZ * * *
"On 8/1/11 at 1052, Unit 1 ERDADS has been restored to an available status."
The licensee notified the NRC Resident Inspector.

UNPLANNED CONTAMINATION AREA
"On 07/31/11 a water leak was found coming through the C-310 North NaF (Sodium Fluoride) trap room ceiling. The leak was coming from a steam condensate header located over the trap room. The leak had created a puddle, approximately 8' by 6', in the trap room. The area was checked by Health Physics and the spill area in the trap room was upgraded to a Contamination Areas at 1030 [CDT]. The condensate water is not contaminated but is spreading contamination from a contamination area above the ceiling. Decontamination of the trap room has been performed; however, due to a small amount of water that continues to leak into the area the area is being recontaminated. Access to the area has been restricted with the contamination area requirements for more than 24 hours.
"This event is reportable as a 24 hour event in accordance with 10 CFR 76.120(c)(1)(i) 'An unplanned contamination event that: Requires access to the contaminated area, by workers or the public, to be restricted for more than 24 hours by imposing additional radiological controls or by prohibiting entry into the area.'
"The NRC Senior Resident Inspector has been notified of this event.

PART 21 - EMERGENCY DIESEL GENERATOR FAILED AIR START MOTOR
The following information was received by facsimile:
"COMPONENT: Air start motors with friction-clutch inertia drives (not pre-engagement type)
"Engine Systems Inc. (ESI) began a 10CFR21 evaluation on 06/16/11 upon receipt of a failed air start motor from Exelon - Clinton. According to information provided by Clinton Nuclear Plant, they experienced a slow start of an EDG during one of their surveillance runs. Subsequent troubleshooting revealed that one of the air start motors had failed. Specifically, it was found that the starter drive had failed which prevented the air start motor from applying full starting torque to the engine. The inspections performed by Clinton indicated the failed motor had what appeared to be excessive preload applied to the springs of the drive clutch which led to spring roll and fragmentation. Clinton had also supplied six remaining air start motors from their inventory to ESI for evaluation of the drive clutch torque setting. The air starters are Pow-R-Quik type LS-60-RH1 and LS-60-LH1 (where RH and LH designate right hand and left hand rotation respectively).
"The evaluation was concluded on 08/01/11 and determined the air motor failure to be a reportable defect as defined by 10CFR21. The starter drive failure was attributed to excessive torque adjustment of the clutch assembly. This overstressed the clutch disc plates which lead to eventual failure of the friction-clutch inertia drive assembly. Failure of the clutch drive renders the air start motor inoperative. Depending upon the configuration of the engine's starting system, an inoperative air start motor could cause excessive starting times or a start failure. Either scenario has the potential to prevent the emergency diesel generator from performing its safety related function.
"Clutch torque testing was performed on the six (6) starters returned from Clinton's inventory. [Results indicate inconsistent clutch settings]. The specified torque setting for the clutch drive is 275-300 ft-Ibs. Of the six starters tested, only one was within specification.
"Based on the test data obtained from the six (6) Clinton starters, all previous shipments of air motors with the friction-clutch inertia drive are suspect for having inconsistent clutch drive torque settings."
Affected users of the air start motors that contain friction-clutch inertia drives include the following: Exelon-Clinton, Entergy-Indian Point 3 and PSE&G-Salem.

RADIATION ALARM AT WASTE FACILITY DUE TO IMPROPER DISPOSAL OF RADIOACTIVE MATERIAL
On 7/28/11 a patient received a 28.3 mCi dose of I-131 as treatment for a hyperthyroid condition. The patient was incontinent and not discharged from the hospital as originally planned. On 7/29/11 a landfill company informed the State of Missouri that a load of waste received from Liberty Hospital caused an alarm on their radioactive portal detector. Investigation identified two (2) soiled diapers which were bagged and returned to the hospital for proper disposal.
Liberty Hospital discussed this incident with the NRC Region III staff who recommended that the hospital report the incident. Also, the RSO for the facility has corrective actions to preclude future incidents under review.

PLANNED MAINTENANCE THAT WILL RESULT IN TECHNICAL SUPPORT CENTER UNAVAILABILITY
"On August 02, 2011, at 0700 EDT, the Technical Support Center will be unavailable due to pre-planned maintenance to maintain the Technical Support Center and Emergency Response Data Acquisition and Display System ventilation system. The TSC is expected to be restored to available status in approximately 12 hours.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures, and the TSC staff will relocate to an alternate TSC location in accordance with applicable site procedures.
"This notification is being made in accordance with 10CFR 50.72 (b)(3)(xiii) due to the potential loss of an emergency response facility (ERF). An update will be provided once the TSC has been restored to normal operation. The NRC Resident Inspector has been notified." |
