TWO TRITIUM EXIT SIGNS STOLEN FROM MOVIE THEATER
The following information was provided by the State of Texas via email:
"On May 26, 2011, the Agency [Texas Department of Health] was notified during routine inspections of the facility's site safety systems, it was discovered that two tritium exit signs were missing from their fixed mounting positions. These signs were affixed to the walls near exits in a secure manner such that they could only be removed by means of removing safety capped mounting screws and then the use of tools to remove them. In this case, it is apparent that these signs were removed by way of vandalism and were essentially pulled off the walls leaving evidence that they were removed without the knowledge of the site personnel. A report was made to the local police department. The signs were installed new in 2010.
"In addition, this same vandalistic act occurred at the same location as reported to the Agency [Texas Department of Health] on February 2, 2011. At that time, four tritium exit signs were removed. A report was made to local law enforcement. The exit signs are Isolite Model 2040-95S-B-15-WS, and each contain 9.5 Curies of tritium."
Texas Incident: # I-8858
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

POTENTIAL FLOODING PATH DISCOVERED
"Operations identified a potential flooding issue in the Intake Structure 1007' 6" level. The areas of concern are the holes in the floor at the 1007' 6" level where the screen wash header penetrates the ceiling of the Raw Water Vault. There are five of these penetrations of concern. Flooding through the penetrations could have impacted the ability of the station's Raw Water (RW) pumps to perform their design accident mitigation functions.
"This eight-hour notification is being made pursuant to 10 CFR 50.72 (b)(3)(v).
"A one foot sandbag berm has been placed around each penetration of concern."
The licensee notified the NRC Resident Inspector.
* * * RETRACTION FROM ERICK MATZKE TO ERIC SIMPSON AT 1142 EDT ON 8/22/11 * * *
"Following additional review of the reported condition, it has been determined that the Raw Water pumps are adequately protected during flooding conditions and that the open penetrations would not impact the ability of the Raw Water pumps to perform their design accident mitigation functions."
The licensee notified the NRC Resident Inspector.
Notified R4DO (Haire).

LOSS OF STARTUP POWER DUE TO FAULT IN SWITCHYARD CAUSES ALL EDGS TO START
"At 0226 PDT on May 26, 2011, Unit 1 startup power was lost following actuation of the 230 KV line pilot wire differential relay 287X. Loss of power to the Unit 1 12 KV startup bus produced an undervoltage signal that caused all Unit 1 emergency diesel generators (EDGs) to start in a standby mode. The EDGs started as designed with no problems observed. No vital loads were affected as a result of the 12 KV bus loss and subsequent undervoltage. The cause of actuation of the differential relay 287X is under investigation at this time.
"At 0255 PDT on May 26, 2011, all Unit 1 EDGs were shutdown and returned to their normal at-power standby configuration.
"Unit 2 startup power was cleared at this time and there was no effect on Unit 2.
"The NRC Resident Inspector has been notified."
