AGREEMENT STATE REPORT - LOST DENSITY GAUGE

The following was received from Texas via email:

"On February 22, 2016, the Agency [Texas] received notice that while under reciprocity in Louisiana, the licensee had lost a Thermo Fisher model 5192 (sn B8191) with 200 milicuries of Cesium-137 (sn 5854CP). Exposure to the public is unlikely due to the design of the device. It is not known whether the device was lost or stolen. The Louisiana Department of Environmental Quality is conducting the investigation. Addition information will be provided as it is received in accordance with SA-300."

The device was lost in Louisiana but reported to Texas by a Texas licensee. The state of Texas notified the state of Louisiana and the NRC. Louisiana will conduct an investigation of the issue.

Texas Incident # I-9380

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.

TURBINE TRIP CAUSING A REACTOR TRIP

"The turbine tripped for an unknown cause followed by a reactor trip. All systems are functioning as designed. Operators have transitioned out of the EOP [Emergency Operating Procedure] network into normal operating procedures. The plant is stable in mode 3."

All control rods fully inserted during the trip and no safety or relief valves lifted. The plant is in its normal shutdown electrical lineup. Emergency Feedwater actuation occurred to restore steam generator levels. The plant expects to make a press release.

The licensee notified the NRC Resident Inspector.
