The flooding in the US Midwest caught my attention this morning because of its scale and the number of fatalities. For example, see here for discussion of record flooding here: http://www.cnn.com/2015/12/29/us/severe-weather-us/
After reading about the flooding I wondered whether nuclear plants located on the Mississippi river might be at risk given the National Weather Forecast is predicting still MORE flooding:

DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY MAJOR RIVER FLOODING WILL CONTINUE ALONG PORTIONS OF THE MISSOURI...MISSISSIPPI...ILLINOIS...MERAMEC AND KASKASKIA RIVERS THROUGH EARLY NEXT WEEK.There are a number of nuclear power plants located in the floodwater area of the Mississippi River. Here is a map from NIRS dated April 2001 https://www.nirs.org/factsheets/mississippiriverpam.pdf:
Located close to the Mississippi is the Callaway Nuclear Power Plant, #12:
Callaway Nuclear Generating Station, Wikipedia, https://en.wikipedia.org/wiki/Callaway_Nuclear_Generating_Station
The Callaway Plant is a nuclear power plant located on a 5,228-acre (2,116 ha)site in Callaway County, Missouri, near Fulton, Missouri. It began operating on December 19, 1984. The plant, which is the state's only commercial nuclear unit, has one 1,190-megawatt Westinghouse four-loop pressurized water reactor and a General Electric turbine-generator. It is owned by the Ameren Corporation and operated by subsidiary Ameren Missouri.
This plant has experienced at least two emergency shutdowns in 2015:

Contaminated water at the site was sampled in 2014:The Ameren Corp. nuclear power plant in central Missouri is shut down for the second time in eight months after a "non-emergency" leak in the reaction control system.

Flooding is not good for nuclear power plants, as described by the Union of Concerned Scientists:
Flood Risk at Nuclear Power Plants, Union of Concerned Scientists, http://www.ucsusa.org/nuclear-power/nuclear-power-accidents/flood-risk-at-nuclear-power-plants#.VoVXmFLw82Y
Flooding can damage equipment or knock out the plant's electrical systems, disabling its cooling mechanisms. This is what happened at the Fukushima Dai-ichi plant in Japan as a result of the March 2011 tsunami, causing severe damage to several of the plant's reactors.
I'm not able to find any notifications or news concerning the status of nuclear power plants impacted by epic flooding in the Midwest. I hope the situation is under control and not a function of a total news blackout.
