UNANALYZED CONDITION THAT COULD HAVE RESULTED IN AN INCREASED MAXIMUM FLOOD LEVEL
"On July 28, 2009, TVA identified, in the Corrective Action Program, the potential to overtop and fail earthen embankments at Cherokee, Fort Loudoun, Tellico, and Watts Bar Dams. This condition could have resulted in an increase in the probable maximum flood (PMF) level at Watts Bar Unit 1. TVA initiated immediate actions to address the condition by conducting additional analyses and the development of contingent actions. Additional actions were developed including the installation of modular flood barriers [which were] completed in December 2009. The barriers increase the effective height of the affected embankments preventing their overtopping and failure. The increase in PMF could have affected plant equipment including the emergency diesel generator system, the essential raw cooling water system, the thermal barrier booster pumps and the control room chillers.
"Additional details regarding the modular flood barriers and the results of TVA's subsequent hydrologic analyses for Watts Bar were discussed in public meetings between TVA and the NRC staff on July 7, 2010 and May 31, 2012, and provided in TVA letters to the NRC dated July 19, 2012, October 30, 2012 and January 18, 2013.
"This report addresses a condition as described in 10 CFR 50.72(b)(3)(ii)(B). Affected safety related equipment is currently operable.
"The NRC Resident Inspector has been notified of this condition."
See related event notifications from Browns Ferry (EN #48724) and Sequoyah (EN #48725).

UNANALYZED CONDITION THAT COULD HAVE RESULTED IN AN INCREASED MAXIMUM FLOOD LEVEL
"On July 28, 2009, TVA identified, in the Corrective Action Program, the potential to overtop and fail earthen embankments at Cherokee, Fort Loudoun, Tellico, and Watts Bar Dams. Prior Browns Ferry Nuclear (BFN) analysis did not consider the potential to overtop and fail the earthen embankments at Cherokee Dam. This condition could have resulted in an increase in the probable maximum flood (PMF) level at Browns Ferry Nuclear Plant Units 1, 2 and 3. TVA initiated immediate actions to address the condition by conducting additional analyses and developing contingent actions. Additional actions were developed including the installation of modular flood barriers [which were] completed in December 2009. The barriers increase the effective height of the affected embankments preventing their overtopping and failure.
"Additional details regarding the modular flood barriers and the results of TVA's subsequent hydrologic analyses were discussed in a public meeting between TVA and the NRC staff on July 7, 2010.
"This report addresses a condition as described in 10 CFR 50.72(b)(3)(ii)(B). Subsequent analyses, completed in November 2012, determined that there are no past operability concerns with this condition at BFN.
"The NRC Resident inspector has been notified of this condition."

AGREEMENT STATE REPORT - SOURCE DISCONNECT OF RADIOGRAPHY CAMERA
The following is a summary of a fax received from the state of Louisiana:
At approximately 10:30 p.m. on the night of July 28, 2009, a radiographer failed to connect the source tube to the camera before he cranked out the source. The cable stop that is attached to the worm cable did not work properly. After dismantling the crankout assembly, the source was hand retrieved and placed back into the camera using the worm cable. A survey was taken to verify that the source was stored safely. The total time of retrieval was approximately 2 minutes.
No personnel were overexposed during this event.
