NEVADA - AGREEMENT STATE NOTIFICATION OF STOLEN MOISTURE DENSITY GAUGE

"Between 1:30 p.m. and 3:30 pm on March 2, 2004, at Vista & McCarran in Reno, Nevada, a Humboldt Scientific Model 5001 moisture density gauge containing 11 millicuries of Cs-137 and 44 millicuries of Am-241:Be, s/n 1854, was stolen from the transport vehicle. The employee indicated the chain securing the gauge to the pickup bed was cut.

" The Reno, Nevada Police Department was notified."

* * * UPDATE FROM STATE OF NEVADA TO ABRAMOVITZ ON 07/13/05 @ 14:41 EDT * * *

The State provided the following information via facsimile:

"The gauge was found in a remote canyon east of Reno Nevada on July 12, 2005. The Storey County, Nevada sheriff's office contacted the Nevada Radiological Health Section who took possession of the gauge on July 12, 2005, and placed it in locked storage pending fingerprinting by law enforcement and leak testing. The shipping case for the gauge was not found but radiation measurements indicated the source was intact and the gauge appeared to be undamaged.

"Gauge serial number is actually 1859, the 1854 serial number listed above was a typographical error."

Nevada event report number NV040001

Notified the R4DO (Spitzberg), NMSS EO (Miller) and TASDO (Whitney via e-mail).

WISCONSIN AGREEMENT STATE REPORT - MEDICAL EVENT

The State provided the following information via email:

"On July 6, 2005, a brachytherapy procedure to treat a bile duct carcinoma using 22 iridium-192 sources totaling 53.9 milliCuries in a ribbon with spacing of 0.5 centimeter between each source was performed. The ribbon was routed through the nasal gastric system to the treatment site (bile duct). A radiograph was taken of the source placement in the bile duct before releasing the patient to a hospital room. The radiograph verified the sources to be in the prescribed location.

"On July 7, 2005, a verification image was taken at 0850 and found that the radioactive sources had moved approximately 5 centimeters toward the gastrointestinal tract. The location of the sources was outside of the intended site. An attempt to reposition the source ribbon by the authorized user was unsuccessful. The authorized user amended the written directive and removed the sources at approximately 1300. The sources were placed in storage.

"The licensee notified the department on July 8, 2005. The Wisconsin Radiation Protection Section will investigate the medical event."

AGREEMENT STATE REPORT INVOLVING A POTENTIAL EXTREMITY OVEREXPOSURE

The following information was received via facsimile:

"A radio pharmaceutical worker received an extremity dose for 2004 of 51 Rem according to her ring badge. 20 Rem of this dose occurred on April 26 - May 2. The licensee thought this may have been an erroneous reading so this is currently considered a potential extremity overexposure until further investigation."

The radiation source is described as mostly Tc-99m with a dose received to the left ring finger of 51050 mRem. The time and date of discovery for this event was 1100 hours on 7/7/05.

TURBINE TRIP/REACTOR TRIP

"On July 13, 2005, at approximately 0917 hours, Unit 1 received a Reactor Protection System (RPS) trip and a Main Turbine trip. All control rods fully inserted into the core. Plant response to the reactor shutdown resulted in a reactor coolant level transient that caused a Low Level 2 signal and subsequent High Pressure Coolant Injection (HPCI) system initiation. The HPCI system started but did not inject into the vessel because reactor coolant level was already recovered by the Reactor Feedwater system. Proper operation of the RCIC system has not been conclusively determined. Both Reactor Recirculation pumps tripped, as expected, from the low reactor coolant level and high pressure transient.

"Additionally, primary containment isolation system actuation signals for valve groups 2, 3, 6, and 8 were received and the valves, that were open, closed as required. The Reactor Building Ventilation System isolated and both trains of the Standby Gas Treatment (SBGT) System automatically started and operated successfully.

"The RPS trip was reset and the HPCI turbine secured. Both trains of the SBGT system were secured. At 1119 hours, the plant exited the scram recovery procedure and entered General Plant Operating procedure 0GP-05, "Unit Shutdown." Investigation into the cause of the RPS and Main Turbine trip is still in progress.

"The plant is currently in Mode 3 (i.e., Hot Shutdown) and activities are in progress to transition to Mode 4 (i.e., Cold Shutdown). The resident inspector has been notified.

"INITIAL SAFETY SIGNIFICANCE EVALUATION

"The initial safety significance of this condition is considered to be minimal. The plant responded as designed to the transient, with the exception of the verification of RCIC system performance, and the plant was safely shut down.

"CORRECTIVE ACTIONS

"An event investigation team has been assembled to determine the cause of the event. Plant response to the event is being evaluated and identified issues will be addressed prior to plant restart."

During the transient, four safety relief valves lifted and reset. The plant is currently in a normal shutdown electrical lineup. Reactor vessel level is being maintained using normal feedwater. The bypass valves are available for cooldown. There was no effect on unit-2.
