AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA COMPONENT FAILURE
The following information was received from the State of Texas by email:
"On June 23, 2016, the licensee notified the Agency [Texas Department of State Health Services] that a radiography camera had failed to lock in position after retracting the source. The ball stop moved about 3/16 of an inch causing the camera to not lock in position after the source was retracted into position. The licensee's radiation safety officer (RSO) obtained the following information about this component failure. The camera was a delta 880 source serial number S7340 at an activity of 52.6 curies. No overexposures were reported to the RSO. An investigation into this event is being conducted by the RSO. The camera has been secured and is located at one of the licensee's sites. Updates will be provided as obtained in accordance with SA300."

AUTOMATIC REACTOR TRIP DUE TO TURBINE TRIP
"At 0841 [CDT] an automatic turbine trip occurred, resulting in an automatic reactor protective system (RPS) actuation due to loss of turbine load. The source of the turbine trip was from the distributed control system (DCS) and is being investigated via a root cause analysis. This was an uncomplicated trip, all systems responded as expected post trip, and the reactor trip recovery procedure was entered at 0852 [CDT]."
The plant is stable in Mode 3 with a normal electrical line up and decay heat removal via steam dumps to the condenser.
The NRC Resident Inspector has been notified.

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS
The following was received from Colorado via email:
"The facility manager completed the documentation for the 2016 Annual General License reports. During his inspection, only 2 of the 4 Tritium exit signs were reported. It is unknown as to what may have occurred with the other two signs as staff has changed since the signs were designated to be used at the facility.
"Pictures were submitted showing the labels on the existing two signs located within the modern fold doors at the school. No serial number was provided on the label from the manufacture Shield Source. The distributor, Isolite, did report serial numbers on the quarterly report to the state."
Colorado Report # CO16-I16-09
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.
