AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN
On May 19, 2011, the Agency [State of Texas] received notification from Texas A & M University's Radiation Safety Officer [RSO] that while removing all tritium exit signs (TES) from a dormitory prior to its demolition, they noted that a TES was missing. The RSO could not provide any additional information at this time. Additional information will be provided as it is received.
Texas Event Number: I-8853
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source.

MANUAL REACTOR TRIP AFTER A MAIN CONDENSER TUBE LEAK
"At 1407 CDT CPNPP [Comanche Peak Nuclear Power Plant] Unit-2 was manually tripped due to indication of a main condenser tube failure. The trip was uncomplicated, all control and shutdown banks fully inserted, neither emergency diesel generator started, all safety systems functioned as designed. Both motor driven and the turbine driven AFW [auxiliary feedwater] pumps started as required to restore steam generator level as a result of the trip. The turbine driven AFW pumps has been returned to auto start status. Currently Unit-2 is in mode 3, no-load Tave 557 degrees F with temperature being maintained with AFW and steam dumps to the main condenser. Recovery actions are currently being planned. All electrical busses are powered from offsite power and grid conditions are stable."
The reactor was manually tripped because of rising sodium concentration in the main condenser/feedwater.
The licensee notified the NRC Resident Inspector, State of Texas, and local government.

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS
The following information was received via e-mail:
"The Iowa Department of Public Health (IDPH) received a telephone notification on May 19, 2011 from the licensee concerning the loss of two tritium exit signs. They stated that during a remodeling process that the signs were taken down and mistakenly placed with the construction trash and sent to a landfill in Pike County, Illinois. The licensee stated that the signs were not retrievable. At the time of the notification, the licensee was not aware of the manufacturer, model number or activity of the signs. IDPH notified the Illinois Emergency Management Agency on May 20, 2011 regarding the exit signs in an Illinois landfill. IDPH was notified by the licensee on June 13, 2011 of the manufacturer, model number, serial number and activity of the sources."
