LOCAL POWER RANGE MONITOR (LPRM) STORED IN SPENT FUEL POOL CANNOT BE LOCATED
"At 1330 [CST] on 11/18/11, Nuclear Engineering reported to Operations that during a Special Nuclear Material (SNM) Physical Inventory they were unable to locate an individual LPRM [Local Power Range Monitor] detector that was believed to be loose in the bottom of the Spent Fuel Pool. Efforts remain in progress to locate the material in the pool."
The licensee stated that during a previous refueling, a 4-detector LPRM string had been removed from the core and placed in the spent fuel pool. At the time, the string had been cut and a single detector at the bottom of the string had fallen to the bottom of the spent fuel pool under the fuel racks. Today, the licensee attempted to retrieve the LPRM detector for placement in a special storage canister in a controlled location that could be easily inventoried. During the retrieval attempt, the licensee could not locate the LPRM detector. There is no indication at this time that the detector has been inadvertently removed from the spent fuel pool and disposed of. The licensee believes that the detector is still in the pool and just needs to be located. The specific information on the detector was not available at the time of this report but the licensee is conservatively assuming the it contained greater than 1 gram of Uranium-233 and is therefore reportable under 10 CFR 74.11.
The licensee has notified the NRC Resident Inspector.

EMERGENCY RESPONSE DATA SYSTEM (ERDS) DISCOVERED TO BE OUT OF SERVICE
"At 0530 EST on 11/18/11, it was identified that communication capability to the NRC ERDS link from the Emergency Response Data Acquisition and Display System (ERDADS) was disabled for St. Lucie Unit 2. The loss of communication occurred due to an issue within the FPL network that was resolved at 1024 EST on 11/18/11. The loss [of the ERDS link was determined to have] occurred on 11/15/11 and is under investigation. The details of this investigation will be documented via the corrective action process. St. Lucie Unit 1 communication capability was maintained by the ERDS modem."
The NRC Resident Inspector has been notified.

TEXAS AGREEMENT STATE REPORT - ABANDONED WELL LOGGING SOURCE
The following information was obtained from the State of Texas via email:
"On November 18, 2011, the Agency [Texas Department of State Health Services] was notified that a licensee had lost, and subsequently abandoned, a logging tool containing a 20 milliCurie cobalt (Co)-60 sealed source at a depth of approximately 5,100 feet down a well in Matagorda County, Texas. The well is a brine solution well that was converted to gas storage; it is a domed salt cavern. There is no rig on the well and the source is at the bottom of the cavern. There is no danger of rupture or exposure. There are no plans to enter the well or cavern in the near future with tubing or wire line. No further action will be taken to retrieve the tool.
"Source information: 20 milliCurie Cobalt-60
"Manufacturer: Eckert and Ziegler

NORTH CAROLINA AGREEMENT STATE REPORT - LEAKING SEALED SOURCE
The following information was obtained from the State of North Carolina via email:
"On November 18, 2011, the RSO of Research Triangle Institute (RTI), License Number 032-0131-1, performed a leak test on a sealed source. The results of the leak test revealed greater than 0.005 microcuries of removable contamination. The leak test showed 0.00517 microcuries of removable contamination. Subsequent surveys continued to show elevated results.
"The survey was performed with a Packard 1900 TR liquid scintillation counter, S/N 103761, calibrated Aug. 24, 2011.
"The source was a Ni-63 Electron Capture source. It had been removed from service and placed in storage in 2008. The source was being leak tested to prepare for disposal. Upon determination that the source was leaking, the RSO double-bagged the source, removed it from storage and segregated it, and contacted the waste broker for instructions on source disposal. The RSO performed contamination surveys of the storage area and the area is clean.
"Source information:
"Isotope: Ni-63, Quantity: 11.3 mCi, Mfg: Franklin GNO Corporation, Drawing No: 801-023, Serial Number: 37, Source date: October 20, 1975
"The licensee met all reporting requirements for the 5-day notification of a leaking source and is preparing a report with additional information."
