TEMPORARY LOSS OF THE RUNNING RHR PUMP DURING A BUS TRANSFER
"PCIS Group 4 isolated during Reactor Protection Power Supply bus transfer. The isolation was not expected by control room operators prior to the power supply transfer. The isolation resulted in the trip of the running RHR pump.
"Operators verified proper isolation and reset the power supply. Shutdown cooling was re-established. The total time out of service was 18 minutes. The time to boil was calculated to be 68 hours prior to the event."
The temperature at the RHR heat exchanger inlet at the beginning of the event was 90 degrees. The temperature at 22:20 was 92 degrees. The other RHR pump was available during this event. The plant is in refueling with the cavity flooded.
The licensee notified the NRC Resident Inspector.
* * * UPDATE AT 1606 EST ON 11/17/05 FROM MICHAEL PLETCHER TO S.SANDIN * * *
"This notification updates the reporting criteria for Event No. 42120. The event was determined to not be reportable per 10CFR50.72 (b)(3)(iv)(A) since it was not due to a valid signal or the result of an intentional manual initiation. This report also satisfies the 60 day telephone notification provisions in 10CFR50.73 (a)(1).
"This notification is being made in accordance with 10CFR50.73 (a)(2)(iv)(A) due to an invalid Primary Containment Isolation System (PCIS) Group 4 actuation that impacted the availability of the Residual Heat Removal (RHR) shutdown cooling system.
"On November 4, 2005, with the reactor shutdown for refueling, an invalid actuation of PCIS Group 4 occurred during transfer of 'A' RPS Bus power supply. The actuation occurred because a breaker supplying power to the 'B' logic was tagged open resulting in completing the PCIS actuation logic. The Group 4 actuation resulted in a complete isolation of the single train RHR shutdown cooling suction path by isolation of RHR-17 and RHR -18 isolation valves.
"The shutdown cooling path was isolated for approximately 18 minutes and the time to boil was approximately 68 hours at the time of the event."
The licensee informed the NRC Resident Inspector. Notified R1DO (Barkley).

AGREEMENT STATE - LOST/MISSING SHIPMENT
"On Monday, October 31, 2005 a shipment of RAM was packaged in Albuquerque, NM by Spectrotech, Svcs. And offered for ground shipment to Kilgore, TX. There were 7 packages, 4 fiberboard boxes and 3 twenty gallon drums, the latter being yellow III, TI=5.0. When the shipment arrived at Kilgore, TX subsite #004 on the RAML03835, Thursday afternoon November 3, 2005, two vials of liquid (Antimony) Sb-124 with 40mCi/each were missing along with the inner shipping container, an ammo box. A tamper seal on the 20 gallon drum was still intact, but this type did not contain a unique serial number. The inventory at Spectrotech has been verified as correct and video surveillance indicates that the materials were packaged and offered for shipment to Conway shipping for ground service. The corporate RSO reported the missing material to the answering service at 1830 hrs, Thursday, 11/03/05. Sb-124 is used for sub-surface field studies in the oil and gas industry. All parties are continuing the investigation."

AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
The State provided the following information via email:
"At approximately 8:00 AM November 7, 2005, the Agency was informed that the Licensee had a pickup truck stolen with a Troxler Model 3430 gauge, SN 28101. The theft occurred at approximately 11:00 PM November 4, 2005. The truck is a silver 2002 Nissan. The Troxler gauge was locked in a 16 gauge steel box with a hardened and anti-theft designed lock and hasp. The steel box is bolted to the frame of the truck. The truck license number is Arizona 997MWT. The gauge contains 8 mCi of Cesium-137 and 40 mCi Am:Be-241.
"Mesa PD is investigating and has issued report number 2005-308-1094
"The Licensee is offering a $500.00 reward for the recovery of the truck and sources. A press release is to be made.
"The Agency continues to look for the source."
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.
