Nebraska emergency management spokesman said there is no safety concerns at the plant.

Two levees were breached Saturday morning north of Fremont, triggering mandatory evacuations.

Nebraska’s sixth largest city has become “an island” amid historic flooding in parts of the Midwest that has left one man dead, forced a National Weather Service office to evacuate and may force a nuclear power plant to shut down out of caution.
Fremont, Nebraska, lies about 40 miles northeast of Omaha and is home to more than 26,000 residents. As of Friday afternoon, flooded roadways coming in and out of the city were closed, leaving the city cut off, the Fremont Tribune reported.
“We are asking people to stay out of the area. We are getting a lot of sightseers, and it’s impeding crew from getting sandbags and fill (material) to where we need to go,” Lottie Mitchell, a spokeswoman for the city, told the Omaha World-Herald.
On Saturday, two levees were breached northwest of the city, triggering a flash flood emergency and mandatory evacuations. One of the two breaches was later patched.
Mike Wight, public information officer for the Nebraska Emergency Management Office, told weather.com they are keeping a close eye on the situation in Fremont.
Wight told weather.com there is “concern” for the nuclear plant but emphasized that it “is perfectly safe.”
“We don’t expect any safety issues but we do expect they will get flooding around them and if it gets too far they will shut it down,” Wight said, adding that it will not be an “issue with power supply” because they can get power from other sources within the grid.
“It is something we’re really watching closely,” Wight said, noting that nuclear power plants “are extremely conservative in their emergency plan.”
“They will go to a new level of status way before they need to be,” Wight said. “(Cooper Nuclear ) is absolutely not having any issues that create a safety issue for anyone.”
Mark Becker, spokesman for the Nebraska Public Power District, previously told the Omaha World-Herald that if the river rises to 45.5 feet this weekend, as projected by the NWS, the nuclear power plant, which accounts for 35 percent of NPPD’s power, will have to be shut down. The water surpassed that level early Saturday and reached an all-time record 45.64 inches.
Wight, who noted that NEMA is in constant communication with the plant, said the plant remained functioning Saturday morning.
On Saturday, Black Hawk helicopters were dropping 1.5-ton sandbags to protect wells that serve the city of Lincoln, home to more than 284,000 people. The wells are located on an island in the rising Platte River.
After surveying the extensive flooding from the air, Nebraska Gov. Pete Ricketts said in a Friday press conference that it was the “most widespread flooding damage we’ve had in the last half-century.”
“Even when we were away from the water system, we saw that the fields were very saturated,” he added.

A Nebraska farmer identified as James Wilke, 50, was killed Thursday after the tractor he was using to attempt to rescue a stranded motorist was carried away by floodwaters, the Omaha World-Herald reported. The incident occurred at Shell Creek near Columbus in eastern Nebraska.
Two other men are missing and presumed dead. Scott E. Goodman, 30, of Norfolk was seen at 4 a.m. Thursday on top of his car near a levee that failed. It was reported that he was later seen being carried away by a surge of water, according to the Norfolk Daily News.
A second, unidentified man may have been swept away Thursday when the Spencer Dam collapsed on the Niobrara River.
When the dam failed, it caused a large ice floe to jam a hole in a small electrical plant, where employees were working. No other injuries were reported. The failure also forced the evacuation of dozens of residents along the river.
Meanwhile, Ericson Dam in north-central Nebraska remains at high risk of failing as the Cedar River continues to rise, according to a report by the NWS.
