LOSS OF 21 OUT OF 101 EMERGENCY SIRENS
"Communications has been lost to 21 sirens out of 101. The loss of communications does not allow the activation of the sirens. Almost all of Harrison County and Pottawattamie County in Iowa are without communications to the sirens. There are compensatory measures in place to ensure notification by local law enforcement in case of an actual emergency to inform the public in these areas.
"This is being reported per 10CFR50.72(b)(3)(xiii) for 'Any event that results in a major loss of emergency assessment capability, off site response capability, or communications capability'.
"An attempt is being made to reboot the siren's communication system in order to restore the sirens. During the reboot, sirens in Washington County, Nebraska, will also lose communications and therefore will not be functional. Local Law Enforcement has been notified in Washington County to perform compensatory measures in case of an emergency."
The NRC Resident Inspector has been informed.
* * * UPDATE FROM DAVID SPARGO TO DONALD NORWOOD AT 0621 EST ON 2/24/2012 * * *
"As of 0518 CST, communications has been reestablished and all sirens were returned to service."
The licensee notified the NRC Resident inspector.
Notified R4DO (Deese).
* * * UPDATE FROM ERICK MATZKE TO HOWIE CROUCH AT 1602 EDT ON 04/05/12 * * *
"Following an investigation of the siren failure, it was determined that all sirens were lost for a period of time from approximately 1809 CST February 23, 2012 until 0518 CST February 24, 2012. The control room was notified at 0215 CST February 24, 2012 and compensatory measures were established for all affected counties in Iowa and Nebraska. No new compensatory measures or actions are or were required."
The licensee has notified the NRC Resident Inspector. Notified R4DO (Haire).

OFFSITE NOTIFICATION DUE TO AN INTAKE STRUCTURE OIL SPILL
"On February 23, 2012, at 0900 CST, an oil leak was identified from a gear box in the intake structure that had leaked into the circulating water cell. Prompt action was taken to stop the leak. Less than or equal to 1 pint of oil was spilled into the circulating water cell and, subsequently, to the Missouri River. The spill has been stopped and clean up of the oil sheen in the intake cell is proceeding. A visible oil sheen was noted on the Missouri River downstream of the station's intake structure near the station's outfall. The gear box has been drained to prevent any further leakage. Notifications will be made per Fort Calhoun Nuclear Station's National Pollutant Discharge Elimination System (NPDES) permit. Samples will be taken for off site analysis to determine the quantity of oil discharged. The State of Nebraska, Department of Environmental Quality and National Response Center will be notified.
"This notification is being made in accordance with 10 CFR 50.72(b)(2)(xi), 4 hour non-emergency notification due to a notification being made to a Government Agency (State of Nebraska, Department of Environmental Quality and National Response Center)."
The licensee has notified the NRC Resident Inspector.
