June 20 UPDATE: On June 17, the NRC published another Event Report by Fort Calhoun. A hole in the floor (caused by what?) has led to flooding, threatening the pumps. “Flooding through this penetration could have impacted the ability of the station’s Raw Water pumps to perform their design accident mitigation functions.”
About 5 million* acres in the US corn belt have flooded, which will spike the cost of gas and food over the next several months. Worse, several nuclear power plants sit in the flooded plains. Both nuclear plants in Nebraska are partly submerged and the FAA has issued a no-fly order over both of them.
On June 7, the Fort Calhoun Nuclear Power Plant filed an Alert with the Nuclear Regulatory Commission after a fire broke out in the switchgear room. During the event, “spent fuel pool cooling was lost” when two fuel pumps failed for about 90 minutes.
On June 9, Nebraska’s other plant, Cooper Nuclear Power Station near Brownville, filed a Notice of Unusual Event (NOUE), advising it is unable to discharge sludge into the Missouri River due to flooding, and therefore “overtopped” its sludge pond.
