Flood Wall Fails at Fort Calhoun Nuke Plant

Fort Calhoun Nuclear Crisis
The Fort Calhoun Nuclear crisis escalated today, when the 2,000 ft flood berm collapsed at 1:25am.  Spent fuel cooling was switched to emergency generators after the main grid was disconnected.
We mentioned previously how US media has been blacking out news coverage of the nuclear crisis, which has been classified by Russia's FAEA as a Level 4 emergency EVEN PRIOR to today's failure of the flood wall. 
We can only pray that the situation does not deteriorate into a melt-down such as the Fukushima nuclear disaster. 
On an investing note...coal is looking like more and more of a no-lose play currently....

From the Omaha World Herald:
The Fort Calhoun Nuclear Station turned to diesel-powered generators Sunday after disconnecting from the main grid because of rising floodwaters.
That move came after water surrounded several buildings when a water-filled floodwall collapsed.

The plant, about 19 miles north of Omaha, remains safe, Omaha Public Power District officials said Sunday afternoon.

Sunday's event offers even more evidence that the relentlessly rising Missouri River is testing the flood worthiness of an American nuclear power plant like never before. The now-idle plant has become an island. And unlike other plants in the past, Fort Calhoun faces months of flooding.

Floodwater surrounded the nuclear plant's main electrical transformers after the Aqua Dam, a water-filled tubular levee, collapsed, and power was transferred to emergency diesel generators.

OPPD officials said the transfer was precautionary because of water leaking around the concrete berm surrounding the main transformers.

Plant operators later reconnected to off-site power once all safety checks had been completed.

Water now surrounds the auxiliary and containment buildings, which are designed to handle flooding up to 1,014 feet above sea level. The river is at 1,006.3 feet and isn't forecast to exceed 1,008 feet.

The U.S. Nuclear Regulatory Commission is monitoring the Missouri River at the plant, which has been shut down since early April for refueling. The Fort Calhoun plant will remain surrounded at least through August as the U.S. Army Corps of Engineers continues dumping unprecedented amounts of water from upstream dams.

The 2,000-foot berm collapsed about 1:25 a.m. Sunday due to “onsite activities,” OPPD officials said. The Aqua Dam provided supplemental flood protection and was not required under NRC regulations.
