Event Notification Report for May 16, 2006

OFFSITE NOTIFICATION DUE TO EMPLOYEE DEATH

"This report is being made pursuant to 10CFR50.72(b)(2)(xi), 4-hour Non-Emergency Report due to potential media interest and the offsite notification of the Callaway County Sheriff's Office of the apparent suicide death of a plant employee on AmerenUE property approximately a half mile outside the Callaway Plant Owner Controlled Area.

"At approximately 0630 on 5/16/06 a contractor employee arriving to work at Callaway Plant reported having seen an automobile parked near the plant. The Callaway County Sheriff's Department was notified and verified the automobile was registered in the name of a plant employee. A Sheriff's Deputy arrived on location and requested a Security Supervisor meet him at the location of the vehicle. At this time it was confirmed that the employee was deceased.

"Callaway Plant Security conducted an initial investigation reviewing a note left by the employee, work areas, and plant access records. The results of the investigation did not indicate anything suspicious or malevolent.

"The licensee has notified the NRC Resident Inspector."

HPCI INOPERABLE DUE TO HPCI DISCHARGE CHECK VALVE BODY LEAK

"The Unit 2 High Pressure Coolant Injection (HPCI) system was declared inoperable due to a leak occurring in the pump discharge check valve (2E41-F005). Specifically, the HPCI system was started as part of a planned surveillance. Personnel observing the HPCI surveillance locally saw water discharging from underneath the insulation on the check valve. The individual, being in constant communication with the Main Control Room personnel, immediately notified the Reactor Operator of the leak. The operator subsequently secured HPCI and isolated the leak.

"The leak was later estimated to be approximately 20 gpm. The water is supplied from the Condensate Storage Tank. All water was contained in the HPCI room and processed by the room sump system.

"Investigations are continuing into the nature and cause of the leak."

The licensee informed the NRC Resident Inspector.

DISRUPTION OF INCOMING AND OUTGOING TELEPHONE COMMUNCIATION CAPABILITY

"On 05/16/2006 at 0945 CDT, the control room was notified that problems with Bell South and Verizon phone services had occurred which disrupted incoming and outgoing telephone communications capability for both Unit 1 and Unit 2. Subsequent attempts from the control room confirmed that the State and County ringdown line was dead as well as the Emergency Notification System line. It was also determined that although outgoing calls from the control room and Emergency Operations Facility via land line were possible, incoming calls could not be received. The NRC Operations Center was contacted via land line at 09:50 CDT to inform the NRC of the issue. Alternate communication via cell phone and satellite phone was established to allow incoming calls from the NRC, State and County. The NRC Senior Resident Inspector was notified of the issue.

"Telephone service was restored at 13:50 CDT which re-established all normal and emergency telephone communications capability."

AGREEMENT STATE REPORT INVOLVING A LOST MOISTURE DENSITY GAUGE

The licensee while transporting a Campbell Moisture Density Gauge S/N MC1391 from one jobsite to another in El Paso, TX, discovered upon arrival that the tailgate of the truck was down and the transport case with gauge were missing. The loss occurred within a sixteen (16) mile radius of the intersection of Hawkins Blvd. and Montana Ave. The licensee acknowledged to the TX Department of Health representative that the instrument had not been properly secured prior to transport. The gauge contains two (2) sources, i.e., 50 millicuries Am-241/Be and 10 millicuries Cs-137.

The licensee informed local law enforcement and the TX Department of Health. TX Incident No. I-8338

**** UPDATE ON 5/17/06 AT 2250 EDT VIA E-MAIL FROM LATISCHA HANSON TO SANDIN ****

Incident # correction: It should be I-8337.

The licensee (RSO) contacted the TX Department of Health representative to indicate that a trucker who is presently in Chicago, IL., found the instrument. The RSO requested the trucker FedEx the gauge back to the licensee. When the State tried the trucker's phone number they received a message that the number is disconnected. No other identification concerning the trucker was available.

The State provided the following information via email:

"On November 24, 2007 at 3:08 pm CST, the Incident Investigation Program (IIP) was contacted by the local El Paso, Texas FBI during the State holiday office closure, that the [moisture density] gauge had been recovered by the local police department and retained for evidence. The individual had made a call to the local fire department reporting that his family may have been exposed to radiation from a piece of equipment on his property. The local fire department in turn contacted the local police department, who discovered it was the reported stolen gauge in May 2006. The local police department contacted the local FBI. The individual was questioned thoroughly by the FBI and finally admitted to having picked up the gauge over a year ago. The FBI asked if it was ok to return the gauge to the owner; IIP gave the ok. The FBI will contact the licensee owner to retrieve the gauge from them. The FBI agent reported the gauge was intact. It is still being decided if the individual will be prosecuted.

"On November 27, 2007 at 3:38 pm CST, IIP received a telephone call from the licensee asking if they could take possession of the gauge and asked if they had any more reporting requirements. They were given permission to take possession, asked to submit in writing to the licensing program that the gauge was found and to give information that gauge was checked and found to be intact. The licensee agreed."

Notified R4DO(Pick), FSME EO (Rathbun), ILTAB (via email), and Mexico (via Fax).


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 injured someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
