AGREEMENT STATE REPORT - STUCK SHUTTER ON GAUGE
This information was provided by the state via email:
"On February 2, 2011, the Agency [State of Texas] was notified by the licensee that the shutter on a Ronan model SA1-F37 nuclear gauge was stuck in the open position. The gauge contained an original activity of 100 milliCuries of Cesium (Cs) - 137. The gauge is mounted on a vessel 100 feet above the ground and does not pose an exposure risk.
"The licensee has contacted the manufacturer and expects the gauge to be repaired in the next few days. Additional information will be supplied in accordance with SA-300."
Texas Incident Number: I-8817

STOLEN LOGGING TOOL WITH CESIUM-137 SOURCE
"On February 1, 2011, the Agency [Texas Department of State Health] was notified by the licensee operating with reciprocity in the State of Texas, that a well logging tool containing a 125 millicurie (original activity) Cesium (Cs) - 137 source was stolen from their vehicle. The source was manufactured by Gulf Nuclear. The tool was removed from its storage location without the shielding for the source. The tool is about ten feet in length and is less than four inches in diameter. The licensee stated that the dose from the source is collimated. The local sheriff was notified of the event. The licensee's representative was in Tyler, Texas and was driving to the location to search for the device. The Radiation Safety Officer stated that the source was approximately 30 years old and the current activity would be about 65 millicuries. The location where the source was stolen is rather remote and heavily wooded. The licensee does not believe that there is a health risk to members of the general public from the source. The source housing is marked with the trefoil symbol and has the words "Radioactive Materials" engraved in it. Additional information will be provided as it is received in accordance with SA-300."

The following information was provided by the state in an email:
"On February 1, 2011, at 1400 hours, the licensee reported that they had completed a visual search and radiological survey in the area the source had been stored and did not find it. He [licensee] stated that he was going to search the roads in the area and stated that he would notify the Agency [State of Texas] if the source was found. Additional information will be provided as it is received in accordance with SA-300."

The following information was provided by the state in an email:
"On February 2, 2011 an Agency inspector [the State of Texas] contacted a scrap yard in Longview, Texas who [scrap yard employee] stated that he had received the source on February 1, 2011. The licensee was contacted and at 1515, confirmed the source was the one that was stolen and had not been damaged. The licensee has taken control of the source. Additional information will be provided as it is received."

Texas Incident # I-8816
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
Although IAEA categorization of this event is typically based on device type, the staff has been made aware of the actual activity of the source, and after calculation determines that it is a Less than Cat 3 event.
Note: the value assigned by device type "Category 3" is different than the calculated value "Less than Cat 3"

SEVERE WEATHER CONDITIONS
"At 1430 on 2-1-2011, due to worsening road conditions from heavy snowfall, a determination was made that there is a loss of plant access for some individuals and some impairment of evacuation routes. This meets the criteria for an immediate notification (8 Hour) per 10 CFR 50.72 (b)(3)(xiii). There is no impact on plant operation, all T/S [Technical Specification] required minimum staffing requirements are satisfied. The weather is predicted to be hazardous until the evening of 2/2/2011. The Missouri Department of Transportation reported they have a plow truck running from Callaway Plant to Jefferson City, MO. They also reported visibility is extremely poor due to blowing snow. The Missouri State Emergency Management Agency duty officer has been notified of the degraded Callaway ERO [Emergency Response Organization] response time and evacuation route issues.
"The NRC Resident Inspector was notified of this event by the licensee."
Two shifts of personnel will be on site throughout this event. Diesel fuel, food, and water are above required minimums.

"As of 1600 [CST] on 2/2/2011, road conditions have significantly improved. Primary evacuation routes have been reported to be passable. There is reasonable assurance of normal ERO response time. NRC Resident Inspector has been informed of the intent of this change and will be notified of this communication."

REACTOR SCRAM AFTER A MAIN TRANSFORMER TRIP
"At 1918 CST on February 1st 2011, LaSalle Unit 1 automatically scrammed due to a MPT [Main Power Transformer] trip and subsequent load reject, both RFP [Reactor Feed Pumps] tripped and [the reactor] scrammed on TCV [Throttle Control Valve] fast closure. 'U' safety relief valve actuated in the relief mode on the turbine trip and has subsequently reset with tailpipe temp returning to normal. As a result of the electrical transient, U1 and U2 RWCU [Reactor Water Cleanup] isolated, and this is not reportable due to being a single train system and there was no isolation in multiple systems. The plant is stable with reactor pressure control to the main condenser via the main steam isolation valves. Unit 2 remained at 96% in coastdown throughout the event. The plant is planned to remain in hot shutdown pending investigation of the cause of the MPT trip and load reject."
All control rods fully inserted on the reactor scram. The cause of the RFP trips was swelling of the reactor water level as expected after a scram. The first out alarm was "turbine control valve fast closure." The plant is experiencing severe weather which may have influenced the MPT trip.
The licensee notified the NRC Resident Inspector.
