Nebraska Flood-Update on Cooper and Fort Calhoun Nuclear Stations

On June 23, 2011, the U.S. Army Corps of Engineers drastically increased the amount of water released from the Gavins Point Dam into the Missouri.

On June 23, 2011, the Nebraska Emergency Management Agency announced that flood waters along the Missouri River at Plattsmouth, Nebraska, south of Offutt Air Force Base, surpassed previous flood records set in 1993 when they reached 36.03 feet. Nebraska City, Nebraska also surpassed 1993 levels with a record 27.79 feet.

Intimidating, perhaps, but not surprising to the Army Corps of Engineers who announced Tuesday, June 21, 2011, that they would increase the amount of water released into the Missouri River from Gavins Point Dam near Yankton, South Dakota from 155,000 cfs, or cubic feet per second, which was the amount they originally planned to maintain for the rest of the summer, to 160,000 cfs on June 23, 2011, anticipating an average increase of four inches in flood water levels.

News flash.

Levee breaks north of Brownville

FYI - That levee is upriver from the Cooper Nuclear Station. Looks like it was the eastern bank of the Missouri that has busted out. They have evacuated three Missouri counties. Have no idea what this will mean to the water levels at Cooper.

They evacuated three Missouri towns (Phelps City, Langdon and Watson). Not counties. Sorry about that.

Chairman of NRC Will Come To Nebraska

The chairman of the Nuclear Regulatory Commission is coming to Nebraska.

The visit by NRC Chairman Gregory Jaczko has to do with both of the state’s nuclear power plants being threatened by the floodwaters of the Missouri River.

Jaczko’s visit is scheduled for Monday.

Missouri River flooding: 1-29 closures (near both of Nebraska’s nuclear plants)

Above article was posted on June 20th. Do not know if those interstate sections are still closed. Now with the new levee break near Brownville Nebraska they supposedly were going to close parts of 136 on the Missouri side of the river.

Some good early news about the levee break.

Levee fails, but Brownville OK

A Missouri River levee three miles north of Brownville, Neb., failed Thursday night, triggering evacuations in Atchison County, Mo.

According to early assessments, the breach posed no threat to the Cooper Nuclear Station near Brownville.

The breach, which came about 9:20 p.m., “will not affect the city of Brownville,” said Renee Critser, the Nemaha County emergency manager.

Wouldn’t a break on the other side of the river and upstream from the nuke plant help it?

Yes, very possible. Nuclear plant is on the west bank. However, been looking at a sat image of the area. Just type in Brownville Nebraska into Google. Heck. Here is a link for you.

Brownville, NE 68321

Now study the ground around the river bed. Nuclear plant is 3 miles south of Brownville. Leeve breach is 3 miles north of Brownville. Breach appears to be out to the east direction. Only Missouri towns evacuated. Now, back to the map, if you zoom out while still keeping the colors still mostly brownish, you can see the old flood plains near the nuclear plant. Successions of flood plain lines go out very far to the east. There appears to be three distinct flood line markings.

Now have a look at this previous flood that happened back in 1993 when dikes and levees burst and the same plant flooded and actually suffered minor damage.

See how flooded the other side of that river was back then ? At any rate, just playing around with the web and seeing what can be done with today's searches and links. Wonder why the MSM is ignoring this stuff ?

Another levee broke earlier Thursday. This one appears to be about 30 miles downstream from the Cooper Nuclear Plant.

Levee breaches near Fortescue

Concerning the media, I do not even remember hearing about the earlier flood in 1993 when the nuclear plant actually experienced minor damage. Wonder who was President then ?

I think unlike what happened in Japan, the operators of the two nuclear plants in Nebraska have plenty of time to implement safety measures--including a full shutdown (e.g., pulling the fuel rods out of the reactor so no reaction occurs) so there is no danger. The scaremongering from the tinfoil hat crowd is just getting a tad too ridiculous....

Scaremongering ? Tell that to the head of the NRC. He will be visiting Cooper on Sunday and Fort Calhoun on Monday. And apparently you have completely missed the story from 1993 where levees broke and Cooper was flooded before they had enough time to prevent damage to the Nuclear Plant. So whether it survives this flood or not, they still have problems.

“Have no idea what this will mean to the water levels at Cooper.”

No effect on the plant I have read today.

So far the news is good on the levee breach 3 miles north of Brownville for Cooper. Water dropped at Brownville by one foot due to breach. However, levels will rise back up to where they were by Sunday. And then rise higher by 3 to 5 inches according to the Army Corps of Engineers. The bottom line is that water wants to go where it has gone in previous floods. Upstream and downstream levee breaches are just pathways the water will take until it eventually gets to where gravity and topography takes it. But so far good news.

Yep. Around Fort Calhoun. The water berm that was surrounding the plant burst. Trying to figure out what is going on, but it appears that water is now up to one of the buildings (auxilary). The claim is that these buildings are water proofed up to a certain height. We shall see I guess. The big problem is Cooper which is still running. The situation could snow ball out of control very quickly. This is the biggest Missouri flood ever recorded by modern man. We will be dealing with this water through August. And the entire Missouri river valley has been hit by heavy rains all weekend. In fact heavy rains hitting again right now. Omaha just got heavy rains and they are currently pumping flood water into Missouri from the rains Saturday morning.

Family back home said we might not be able to get there for the Fourth. No good way to get across the Missouri.

Fort Calhoun is 40 or so miles from my parents house. Not a good thing.

It didn’t break. Someone won’t be driving a skid loader in the near future.

” No good way to get across the Missouri.”

I understand the main I 80 route through Omaha is still ok. And I thought 680 over and across through Blair was still ok?

My guess is you want to be up wind. In fact, some may not be able to get up wind because they cannot cross the Missouri traveling east to west. Access roads are a mess.

We have new reports now about what happened at Fort Calhoun. See below links. The breaking of the levee surrounding the plant knocked out the diesel generators or what ever on site power they were using. They had to switch to batteries while they switched to off site power. They are now running on off site power. Darn good thing they ran that line ? Plan is to repair the levee dam. And note - Fort Calhoun is not running. Just holding a lot of dirty rods.

Rain should be leaving later today until next weekend. Should give them sometime to assess the damage.

Oh, and the GE/NRC spokesman said these are not the droids you are looking for.

Later.

There are conflicting stories out there now. This one claims that the levee break at Fort Calhoun caused the plant to routinely switch to backup diesel power and disconnect from off site power. After checking off-site power, they switched back to off-site power.

Highway 30 through Blair is shut down, and I 29 north to Onawa is closed.

My parents live north of Omaha, and my mother in law north of Sioux City. We can get to either one, but it will take some doing.

They can head west if needed. That is up wind for the most part.

I heard from friends near by that the diesel generators are knocked out. Why they build those in the basement I will never know. The new line is good, but with all the storms that is a thin life line.

They should have good weather for a few days. Some reports claim water is seeping into buildings. Nothing confirmed on that yet.

The net is swimming right now with reports of a “10 Mile Mandatory Evacuation Area” being implemented right now.

Anyone able to confirm this or dispel this as a rumor?

Around Fort Calhoun ? Been doing google searches on Fort Calhoun and Cooper Nuclear for at least a week. Have not seen anything about evacuation zones. We do have a US senator asking the Army Corps of Engineers to consider the Nuclear Plants when they determine water releases from dams. Apparently they were not considering the Nuclear Plant flooding.

Found the web blog that appears to be the source of the rumor. This guy actually broke something important early on with regards to Fukushima, if I remember right. He states all references to the evacuation order were scrubbed from the MSM, well that could explain why I have not seen any mention. But it could also be just a false report. His page is quite extensive though, and he has an ABC video where the evacuation supposedly is discussed. Have no idea myself, will check it out later today when I have time.

FYI - The Army Corps of Engineers has stated that there will be consequences for people spreading false rumors. Just posting the above link for informational purposes and because you asked about it.

Only if they lose cooling for the Spent Fuel Pool. That would require off site power loss, backup generator loss and the batteries running out of power. The odds of that are pretty slim, however, if we lose one of those big dams upstream, all bets are off.

At any rate, some of the videos of Fort Calhoun are very depressing. They must have a couple dozen sump pumps moving water out from sandbagged buildings and structures. And this flood is supposed to last through August.

Watched the ABC video at the link above and see the problem. The NRC Chairman Gregory Jaczko was stating that all Nuclear Plants have a 10 mile evacuation plan around them in case of an emergency release situation. The ABC reporter however lead Jaczko’s statement with a poorly worded statement that the evacuation zone had been implemented. The reporter meant to state the evacuation zone was already pre-planned in case of an emergency.

Okay thanks....

It very much appeared you were saying radiation was probable / likely. And we all should be looking to be up-wind.

Thanks for clearing that up........
