Cooper Nuclear Station submitted two reports to the Nuclear Regulatory Commission Operations Center on Sunday: a NOUE because of the river level (Fort Calhoun did this last week as well), and a notification that oil had been released into the Missouri River from a training facility because levees are being over topped. It’s noted that the training facility is lower than plant grade and that there is no radiological contamination in that area.

UNUSUAL EVENT DECLARED DUE TO MISSOURI RIVER FLOODING
At 0402 CDT on 6/19/2011 a Notification of Unusual Event was declared due to the elevation of the Missouri River reaching 899.1 feet above mean sea level. This is above the Emergency Action Level HU1.5 elevation of 899 feet. The Missouri River is expected to crest at 899.5 feet within the next couple of days. It is expected that the elevation of the Missouri River will remain above 899 feet for most of the summer.
Actions are in progress in accordance with the site flooding procedure, including strategic placement of sand bags at building entrances and important facilities. There is no major plant equipment out of service at this time. Personnel access to the site is not presently impeded. Emergency evacuation routes remain available.

RELEASE OF OIL TO THE MISSOURI RIVER
“Notification is being made to the Nebraska Department of Environmental Quality regarding the release of oil to the Missouri River from the Cooper Live Fire Training Facility. Currently, levees separating the Training Facility and the Missouri River are being over topped due to flooding of the Missouri River. This condition has resulted in flooding of the burn pits in the fire training facility, with the subsequent release of the residue which includes unburned fuel oil. Any release of this water containing oil to the Missouri River is uncontrolled at this time. Then is no radiological contamination in this area.
“Current river level is approximately 900.5 ft. MSL, approximately 3.0 feet below plant grade elevation. The fire training area is lower than plant grade. A press release is not planned at this time. River level is currently projected to be 899 ft. by Wednesday 6/22.”
