"At 0226 CDT on September 14, 2014, MNGP [Monticello Nuclear Generating Station] experienced a trip of the 12 Reactor Recirc Pump. The subsequent power drop and lowering of recirculating water flow resulted in the plant being outside of the analyzed region of the Power to Flow Map. Operators promptly restored operation within the analyzed region per procedural guidance. This event has been determined to be a condition where the plant was in an unanalyzed condition that significantly degrades plant safety and is reportable under 50.72(b)(3)(ii). The plant is in stable condition at 51% power and the health and safety of the public were not affected. The investigation of the cause of this event is in progress."
The licensee will notify the NRC Resident Inspector.

"Further analysis has determined that the condition did not significantly degrade plant safety.
"General Electric Hitachi was requested to review the event and confirm the SIL653 guidance remains applicable for MELLLA+ [Maximum Extended Load Line Limit Analysis] operation. This review was completed and the conclusions of SIL653 remain valid . The SIL states that: 'unplanned events that result in the plant exceeding the licensed upper boundary do not constitute a safety concern. The consequences of such unplanned events are bounded by the GE safety analysis of limiting events initiated from within the licensed operating domain.
"Stability monitoring and protection using Detection and Suppression Solution Confirmation Density remained available throughout the event (oscillating power range monitors).
"The NRC Resident Inspector has been notified."

The following information was obtained from the State of New York via fax:
"New York State Department of Health was notified on October 31, 2014 by the Radiation Safety Officer of Materials Testing Laboratories, Inc. of the theft of a moisture/density device from a locked vehicle on Friday October 31, 2014. The device is identified as a Troxler Model 4640, serial no. 722 containing 8 millicuries of Cesium 137. The device was apparently being stored within the locked vehicle. The transport case was tethered to the frame of the vehicle with the cable locked to the hasp of the carrying case. The operator of the device discovered that the back lift gate to the 2009 Chrysler Aspen SUV was opened and the lock was removed from the carrying case. The device was stolen from the transport case. Nothing else in the vehicle was stolen.
"Local law enforcement have responded and are investigating."
New York Event ID No.: NY-14-04
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.

The following information was obtained from the State of Ohio via email:
"At 12:40 pm [EST] on Nov. 3, 2014, the RSO [Radiation Safety Officer] from the University of Cincinnati Medical Center called the ODH-BRP [Ohio Department of Health - Bureau of Radiation Protection] to report receipt of a contaminated package that exceeded the contamination levels for reporting that occurred that morning. The 300 centimeters squared wipe of the outside of the package yielded 1433 dpm per centimeters squared. The wipe on the inside of the package yielded a contamination rate of 29,244 dpm per centimeters squared. The TI [transportation index] listed on the package was 0.9, and the licensee measured 2.0 at the time of the package receipt. The package was a shipment of two doses of 15 mCi of F-18 FDG with a reference time of 1100 [EST]. The receiving licensee has placed the package in storage for radioactive decay.
"The shipping nuclear pharmacy licensee, PETNET, was notified by the University of Cincinnati Medical Center of the package contamination. The licensee's courier arrived back at the pharmacy for vehicle and personnel contamination [survey] at approximately 1310 [EST]. The driver and the vehicle were surveyed and did not have any measurable contamination.

| Event Text AGREEMENT STATE REPORT - DAMAGED GUIDE TUBE ON INDUSTRIAL RADIOGRAPHY EQUIPMENT
The following was received from the State of Texas via email:
"On November 3, 2014, the Agency was notified by the licensee's Radiation Safety Officer (RSO) that one of his crews was unable to retract a 34.9 curie cobalt-60 source into a QSA Global 680A exposure device. The crew was performing radiography at a field site [in Houston, TX] using a magnetic stand to support the guide tube and collimator. The stand fell on the guide tube crimping the guide tube in two places about one inch apart. The radiographer attempted to retract the source, but it would not go past the crimped section of the guide tube. The radiographer returned the source to the collimator.
"One of the radiographers contacted the site RSO(SRSO). A recovery team was sent to the location to retrieve the source. The team slid a steel plate below the collimator. The guide tube was pulled to free the collimator from its holder causing it to drop onto the steel plate. The collimator was approached from the shielded side and using a pair of tongs, the collimator was rolled to face the outlet port towards the steel plate. Six bags of lead shot were placed on the collimator. The dose rate at the crimped section of the guide tube was then measured at 200 millirem per hour. Additional bags of lead shot were placed on the collimator. The licensee's first attempt to remove the crimps in the guide tube using channel locks was unsuccessful. The licensee then removed the outer coating on the guide tube in the areas the tube was crimped and then used channel locks to remove the crimps. This was successful and the source was returned to the fully shielded position.
"The highest exposure to any individual involved in the event was seven millirem. The licensee reported no exposures were received to members of the general public due to this event. The guide tube was taken out of service. The exposure device and crankout device were inspected and returned to service. The source was leak tested, but the results have not been received.
" Additional information will be provided as it is received in accordance with SA-300."
