AGREEMENT STATE REPORT - POSSIBLE OVEREXPOSURE DURING TRANSPORTATION

"On August 13, 2009, at 1630 the Agency [Texas Department of Health] received a call from the licensee's Radiation Safety Officer (RSO) stating that they had shipped a 2.5 curie Cesium 137 source via common carrier to Tyler, Texas from Van Buren, Arkansas. Some time after receiving the source in Tyler, Texas, the licensee discovered that the source had been shipped in a container designed to carry Americium. The licensee recreated the event and determined that the dose rate in the cab of the transport truck was 25 millirem per hour. The trip was estimated to take six hours to complete, so the dose to the driver was calculated to be 150 millirem for the trip. The licensee is attempting to identify the driver and will determine additional dose rates required for shipping during their investigation. A survey was conducted by the licensee prior to the package leaving Arkansas and the individual who performed the survey stated that he did not see any unusual dose rates from the package. The RSO stated that they will provide a copy of the survey and additional information as it is gathered. This Agency [Texas Department of Health] will perform an onsite investigation on August 14, 2009, and will provide additional information to the NRC when prudent."

AGREEMENT STATE REPORT - SR-90 SOURCE FOUND IN MAIL

The following report was received via e-mail:

"Customs called to report a detection at the international post office at DFW [Dallas/Ft Worth] airport. The source was contained in a package with some other materials including a couple of electronic devices, a small plastic container about the size of a contact lens holder, some dice and other articles. The package was being mailed to [REDACTED], Ft. Worth, TX. 76179. Customs provided pictures of the package and contents. The radioactive material was identified as Sr-90. Inspector surveys measured 0.3 mrem closed window, 60 mrem open window."

The State of Texas notified EPA, FBI, and ICE.

LOSS OF EMERGENCY RESPONSE DATA SYSTEM AND SAFETY PARAMETER DISPLAY SYSTEM DUE TO COMPUTER PROBLEMS

"At 1210 hours on 08/17/09, reactor operators noticed [the] Plant Integrated Computer System was beginning to fail. This computer system also performs the Safety Parameter Display System (SPDS) and Emergency Response Data System (ERDS) functions. Investigation by computer maintenance personnel was initiated. It was determined that [the] Safety Parameter Display System (SPDS) and Emergency Response Data System (ERDS) were not reliable. Redundant, normal control room indications are still available to the operators.

"At 1955 hours on 08/17/09, the Plant Integrated Computer System was restored to service, including the Safety Parameter Display System (SPDS) and Emergency Response Data System (ERDS) functions.

"A few hours later at 0004 hours on 08/18/09, the Plant Integrated Computer System failed, including loss of Safety Parameter Display System (SPDS) and Emergency Response Data System (ERDS). Reactor power was lowered by 0.3% from the initial authorized limit of 94.4% to 94.1% due to the loss of the core thermal power heat balance provided by the computer system.

"Since the Unit 2 SPDS and ERDS computer systems were not available for greater than an 8 hour time period, this is considered a Loss of Emergency Assessment Capability and therefore reportable under 10CFR50.72(b)(3)(xiii)."

The licensee has notified the NRC Resident Inspector.

* * * UPDATE AT 1321 ON 8/17/2009 FROM JIM HUFFORD TO KARL DIEDERICH * * *

"As of 1336 hours on 08/18/09, Unit 2 ERDS and SPDS were restored to normal operation. Unit 2 reactor power was returned to full power of 94.4% shortly thereafter."

The licensee has notified the NRC Resident Inspector. Notified R1DO (Conte).

HPCI TURBINE STOP VALVE FAILS IN MIDPOSITION

"At 0920 on 08/18/2009, the Unit 1 HPCI turbine stop valve (FV15612) showed dual indication following performance of the weekly functional test of the HPCI lube oil system. Subsequent investigation revealed that the valve stem was not in the full closed position. LCO 3.5.1 for the HPCI system was entered at 0920 on 08/18/2009. An investigation is in progress to determine the nature of the problem.

"This incident is being reported as an event or condition that could have prevented fulfillment of a safety function required to mitigate the consequences of an accident in accordance with 10CFR50.72(b)(3)(v)(D)."

The HPCI pump was declared inoperable. This is a 14 day LCO.

The licensee notified the NRC Resident Inspector.
