Parts of Nebraska Nuclear Facility Already Under 2 Feet of Water ... But - So Far - Emergency Flood Walls Are Protecting Electrical Equipment
ABC news reports that there is already 2 feet of water at some parts of the Fort Calhoun nuclear plant:
Although the Fort Calhoun plant ... is surrounded by an eight foot tall and 16 foot wide protective berm, two feet of water have already made its way to several areas of the Fort Calhoun plant, but authorities say there is no immediate danger at either plant.
nuclear regulators say two Nebraska nuclear power plants have
protected critical equipment from the rising waters of the Missouri
River even though flooding has reached the grounds of one of them.
Parts of the grounds are already under two feet of water as the swollen Missouri overflows its banks. But the Omaha Public Power District, which owns the plant, has built flood walls around the reactor, transformers and the plant's electrical switchyard,
the NRC said."They've surrounded all the vital equipment with berms,"
Dricks said.An 8-foot-tall, water-filled berm, 16 feet wide at its
base, surrounds the reactor containment structure and auxiliary
buildings, the NRC says. The plant has brought in an additional
emergency diesel generator, water pumps, sandbags and firefighting
equipment as well, according to regulators.
The 2 feet of water is in areas like parking lots, not within the reactor building itself.
The Omaha World-Herald notes that the river is expected to rise an additional 4-5 inches at the Fort Calhoun and Cooper nuclear plants:
Tuesday, the Army Corps of Engineers announced that releases from
Gavins Point would increase another 7 percent to 160,000 cubic feet per
That will add about 4 to 5 inches in the river’s level
at Fort Calhoun and Cooper Nuclear Stations, according to information
from the corps and the National Weather Service...
The NRC has
added two inspectors and a branch chief to the permanent two-person
inspection crew at Fort Calhoun station, said Lara Uselding,
spokeswoman. They are providing around-the-clock oversight there.
