Berm Protecting Fort Calhoun Nuclear Plant Breaks … Plant Flooded, on Emergency Diesel Generators

I reported Thursday:

Here are photos of the Aqua Dam installed outside the Fort Calhoun plant courtesy of the official OPPD Flood and Outage blog:

Unfortunately, the berm at Fort Calhoun has now broken. As the New York Times notes:

Fort Calhoun, took two steps backward on Sunday. In the pre-dawn hours, a piece of heavy equipment nicked a temporary rubber berm, 8 feet high and 2,000 feet long, and it deflated. And water there began to approach the switchyard, where grid power enters the complex, so operators started up their diesel generators.

Similarly, CNN reports:

A water-filled berm protecting a nuclear power plant in Nebraska from rising floodwaters collapsed Sunday, according to a spokesman, who said the plant remains secure.

Some sort of machinery came in contact with the berm, puncturing it and causing the berm to deflate, said Mike Jones, a spokesman for the Omaha Public Power District (OPPD), which owns the Fort Calhoun plant…

The 6 to 12 inches of rainfall in the upper Missouri basin in the past few weeks is nearly a normal year’s worth, and runoff from the mountain snowpack is 140% of normal, according to forecasters.

Reuters notes:

More than 2 feet (60 cm) of water rushed in around containment buildings and electrical transformers at the 478-megawatt facility located 20 miles (30 km) north of Omaha.

The Omaha World-Herald adds some details:

Water surrounded several buildings at the Fort Calhoun Nuclear Station on Sunday after 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 Sunday after the Aqua Dam, a water-filled tubular levee, collapsed, and power was transferred to emergency diesel generators.


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.


Water now surrounds the auxiliary and containment buildings, which are designed to handle flooding up to 1014 feet above sea level.


The NRC said there is a separate, earthen berm to protect the electrical switchyard and a concrete barrier surrounding electrical transformers.

The New York Times points out some hopeful news:

Fort Calhoun shut down in April for refueling and stayed closed because of predictions of flooding, so its cooling requirements are much smaller now. It is “designed to remain secure” at a river level of up to 1,014 feet above sea level, and the river level is stable now at 1,006.5 feet ,according to the Omaha Public Power District, the operator.

I also noted Thursday:

There are also dry cask storage units at the facility, outside of the main building. Here are pictures of the dry casks being delivered to the facility.

The area in red shows where one writer (Tom Burnett) believes the dry cask units are located.

Burnett also claimed that the fuel casks were outside of the flood protection barrier. He appears to be correct. Specifically, the Iowa Independent reports:

A Nuclear Regulatory Commission spokesman told The Iowa Independent Friday that dry cask storage of spent nuclear fuel rods at two Nebraska facilities are not being protected from flood waters because the situation poses no public or environmental threat.


Following an earlier report published by The Iowa Independent about flooding at the nuclear facilities, questions were raised about the placement of dry cask storage of spent nuclear fuel rods with some questioning if the facilities storing these rods were within flood protection barriers.

“They are not within the flood protection barrier,” Dricks said. “There’s no reason for them to be. Those are large, sealed canisters that are bolted down — no risk with the floodwaters.”

Spent fuel rods are first cooled in a spent fuel pool for a year before being placed in dry cask storage. The fuel is surrounded by inert gas inside a large container, typically steel cylinders that are either welded or bolted closed. That container is then surrounded by another protective layer — typically steel or concrete — as a further radiation shield. Additional technical information on the process of dry storage can be found in a December 2010 report by the U.S. Nuclear Waste Technical Review Board (PDF).

Because of their protected state, Dricks said, there is no danger associated with these storage casks being exposed to the ongoing flood.

Indeed, it does appear that most dry cask storage units are vacuum-sealed. So if safety procedures were followed, the spent fuel rods stored in dry casks at Fort Calhoun and Cooper nuclear reactors have a fairly good chance of riding out the flood.

However, if corners were cut or the floodwaters cause somthing massive to bang into the dry casks, it could get dicey

Finally, CBS news reports that some silos for minutemen nuclear missiles at the Minot Air Force base have flooded:

Minot is best known as home to an Air Force base, which oversees 150 Minuteman III missiles in underground launch silos scattered over 8,500 square miles in northwest North Dakota.

Col. S.L. Davis, commander of the 91st Missile Wing, said there was some “localized flooding” at a handful of missiles sites because of the wet spring and summer. But he said the silos are designed to safely handle some water and protective measures were taken at a few sites similar to what’s done in preparation for spring runoff from snowmelt.

I don’t think that nuclear missiles – unlike nuclear reactors – need to be cooled or need a constant electrical supply in order to avoid disaster. So while this sounds scary, I assume the risks are actually low.

Support #altnews & keep Dark Politricks alive

Remember I told you over 5 years ago that they would be trying to shut down sites and YouTube channels that are not promoting the "Official" view. Well it's happening big time. Peoples Channels get no money from YouTube any more and Google is being fishy with their AdSense giving money for some clicks but not others. The time is here, it's not "Obama's Internet Cut Off Switch" it's "Trumps Sell Everyones Internet Dirty Laundry Garage Sale".

It's not just Google/YouTube defunding altenative chanels (mine was shut), but Facebook is also removing content, shutting pages, profiles and groups and removing funds from #altnews that way as well. I was recently kicked off FB and had a page "unpublished" with no reason given. If you don't know already all Facebooks Private Messages and Secret Groups are still analysed and checked for words related to drugs, sex, war etc against their own TOS. Personally IU know there are undercover Irish police moving from group to group cloning peoples accounts and getting people booted. Worse than that I know people in court at the moment for the content they had on their secret private group. Use Telegrams secret chat mode to chat on, or if you prefer if you need to or buy a dumb phone with nothing for the NSA to hack into if you are that paranoid.

So if your not supporting this site already which brings you news from the Left to the Right (really the same war mongering bollox) then I could do with some. Even if it's just £5 or tick the monthly subscription box it will be much appreciated. Read on to find out why/


Any support to keep this site would be appreciated. You could set up a monthly subscription for £2 like some people do or you could pay a one off donation as a gift.
I am not asking you to pay me for other people's articles, this is a clearing house as well as place to put my own views out into the world. I am asking for help to write more articles like my recent
false flag gas attack to get WWIII started in Syria, and Trump away from Putin. Hopefully a few missiles won't mean a WikiLeaks release of that infamous video Trump apparently made in a Russian bedroom with Prostitutes. Also please note that this article was written just an hour after the papers came out, and I always come back and update them.

If you want to read JUST my own articles then use the top menu I have written hundreds of articles for this site and I host numerous amounts of material that has seen me the victim of hacks, DOS plus I have been kicked off multiple hosting companies, free blogging sites, and I have even had threats to cease and desist from the US armed forces. Therefore I have to pay for my own server which is NOT cheap. The more people who read these article on this site the more it costs me so some support would be much appreciated.

I have backups of removed reports shown, then taken down after pressure, that show collusion between nations and the media. I have the full redacted 28/29 pages from the 9.11 commission on the site which seems to have been forgotten about as we help Saudi Arabia bomb Yemeni kids hiding in the rubble with white phosphorus, an illegal weaapon. One that the Israeli's even used when they bombed the UN compound in Gaza during Operation Cast Lead. We complain about Syrian troops (US Controlled ISIS) using chemical weapons to kill "beautiful babies". I suppose all those babies we kill in Iraq, Yemen, Somalia and Syria are just not beautiful enough for Trumps beautiful baby ratio. Plus we kill about 100 times as many as ISIS or the Syrian army have managed by a factor of about 1000 to 1.

I also have a backup of the FOX News series that looked into Israeli connections to 9.11. Obviously FOX removed that as soon as AIPAC, ADL and the rest of the Hasbra brigade protested.

I also have a copy of the the original Liberal Democrats Freedom Bill which was quickly and quietly removed from their site once they enacted and replaced with some watered down rubbish instead once they got into power. No change to police tactics, protesting or our unfair extradition treaty with the USA but we did get a stop to being clamped on private land instead of the mny great ideas in the original.

So ANY support to keep this site running would be much appreciated! I don't have much money after leaving my job and it is a choice between shutting the server or selling the domain or paying a lot of money just so I can show this material. Material like the FSB Bombings that put Putin in power or the Google no 1 spot when you search for protecting yourself from UK Police with "how to give a no comment interview". If you see any adverts that interest you then please visit them as it helps me without you even needing to give me any money. A few clicks per visit is all it takes to help keep the servers running and #altnews alive!

However if you don't want to use the very obvious and cost free ways (to you) to help the site and keep me writing for it then please consider making a small donation. Especially if you have a few quid sitting in your PayPal account doing nothing useful. Why not do a monthly subscription for less money instead. Will you really notice £5 a month?
