Alert level 4 the USA on a central Nebraska?




by stipe » 16/06/11, 16:44

For info, it would seem that:
The Omaha nuclear power plant in Nebraska is besieged by rising Missouri water.

Info remarks?

I imagine the situation is under control ... :?

and video of the water in the power plant on June 6 !!
On June 6, 2011, the Fort Calhoun pressurized water nuclear reactor 20 miles north of Omaha, Nebraska entered emergency status due to imminent flooding from the Missouri River. A day later, there was an electrical fire requiring plant evacuation. Then, on June 8th, NRC event reports confirmed the fire resulted in the loss of cooling for the reactor's spent fuel pool.


Nobody talked about it !!!

True or false ???

Electrical Fire Knocks Out Spent Fuel Cooling at Nebraska Nuke Plant
by John Sullivan
Special to ProPublica June 9, 2011, 11:20 am

A fire in an electrical switch room on Tuesday briefly knocked out cooling for a pool holding spent nuclear fuel at the Fort Calhoun nuclear plant outside Omaha, Neb., Plant officials said.

The safety of deep pools used to store used radioactive fuel at nuclear plants has been an issue since the accident at Japan's Fukushima nuclear plant in March. If the cooling water a pool is lost, the used nuclear fuel could catch fire and release radiation.

As ProPublica reported earlier, fire safety is a continuing concern at the country's 104 commercial reactors, as is the volume of spent fuel piling up at plants.

Officials at Fort Calhoun said the situation at their plant came nowhere near to Fukushima's. They said it would have taken 88 hours for the heat produced by the fuel to boil away the cooling water.

Workers restored cooling in about 90 minutes, and plant officials said the temperature in the pool only increased by two degrees.

The fire, reported at 9:30 am, led to the loss of electrical power for the system that circulates cooling water through the spent fuel pool, according to a report from the Nuclear Regulatory Commission. A chemical fire suppression system discharged, and the plant's fire brigade cleared smoke from the room and reported that the fire was out at 10:20 am, the NRC said.

Mike Jones, a spokesman for the plant's owner, the Omaha Public Power District, said Fort Calhoun has a backup pump to provide water to the spent fuel in case the main system is lost. That pump, which runs on a separate power supply from the rest of the plant, was inspected and standing by on Tuesday, but plant operators restored main power to the pool before the emergency pump was needed, he said.

Fort Calhoun's single reactor has been shut down since April for refueling. The plant had already been operating under a heightened level of alert because of nearby flooding on the Missouri River, the NRC said. The cause of the fire remained under investigation this morning.

Nebraska, Missouri nuclear power plant river flood conditions

The Fort Calhoun nuclear power station in Fort Calhoun, Nebraska, currently closed for refueling, is surrounded by the flood waters of the Missouri River, Tuesday, June 14, 2011. On Tuesday, discharges at the Point Gavins dam in the South Dakota has hit the maximum forecast amount of 150 cubic feet of water per second, which is expected to raise the Missouri River 000-5 feet above the flood level in most of Nebraska and Iowa.

oops! what is happening ?

It happens that there was a serious incident on June 8 at this plant. Fire starts!

Nebraska Nuclear Plant Lost Cooling System After Fire

WASHINGTON — A nuclear power plant north of Omaha, Neb., On Tuesday briefly lost the ability to cool a pool of used nuclear fuel after a fire at the site, the US Nuclear Regulatory Commission said.

The NRC said the plant recovered cooling ability without activating backup systems and "temperatures in the pool remained at safe levels." The public was not in danger because the plant has been shut down since early April for a refueling outage, the agency said.

Spent fuel pools in the US have received increased scrutiny after a recent crisis in Japan involving potentially overheated nuclear fuel and the release of dangerous radiation.

The agency declared an alert, the second of four emergency classes, at 9:40 am, 10 minutes after "an indication of fire" in a building at the plant. The NRC didn't disclose the cause of the fire. Automatic fire control systems activated and the fire was out by 10:20 am, the agency said. The plant is operated by the Omaha Public Power District.

Nuke plant lost spent fuel pump in suspected fire

ATLANTA (AP) - A nuclear power plant in Nebraska briefly lost the pump used to cool spent nuclear fuel during a suspected electrical fire.

Utility officials said the fire Tuesday damaged an electrical system used to run a pump at the Fort Calhoun Station that recirculates water in a pool holding hot, radioactive nuclear fuel that has been used.

The pump was out of commission for an hour before the system was restored
. Omaha Public Power District spokesman Mike Jones said the company had backup equipment but didn't need to use it. Jones initially said that plant operators deliberately took the pump offline to respond to the fire.

If a pool pump fails for several days and is not fixed, cooling water could boil away and eventually cause radioactive releases.

Damn it, no French media reports that! : - #

http://stienster.blogspot.com/2011/06/nebraska.html
it started on the 6th with a fire, then a loss of control, then resumed, of the cooling means

So it says that there was an interruption in the circulation of the cooling of the pool of used fuels not an hour but an hour and a half (90 minutes in the text).
It raised the pool water temperature by 2 °.


... Workers restored cooling in about 90 minutes, and plant officials said the temperature in the pool only increased by two degrees.

The fire, reported at 9:30 am, led to the loss of electrical power for the system that circulates cooling water through the spent fuel pool, according to a report from the Nuclear Regulatory Commission.

Are these reassuring statements true or false?

When it goes wild like in Cherno-Fukushima, we will know that it was a lie.

Otherwise, luckily it was true !!

Nuclear cannot be infallible in perpetuity, without huge catastrophes !!

We also see that the fine American strategists of the Nuke had to take high security courses for classified installation in France or in Fukushima and also placed their weapon of mass extinction within reach of flood .... : Mrgreen: :| :frown: : Cry: : Evil:

The situation is said to be "safe".

The power station was at a standstill while refueling, and given the arrival of the flood, they had not restarted.

No danger seen at reactor

Friday June 17, 2011

Despite the stunning sight of the Fort Calhoun nuclear reactor surrounded by water and the weeks of flooding that lie ahead, the plant is in a safe cold shutdown and can remain so indefinitely, the reactor's owners and federal regulators say.

“We think they've taken adequate steps to protect the plant and to ensure continued safety,” Victor Dricks, spokesman for the Nuclear Regulatory Commission, said Thursday.

Tim Burke, vice president at Omaha Public Power District, said the plant's flood barriers are being built to a level that will protect against rain and the release of record amounts of water from upstream dams on the Missouri River.

“We don't see any concerns around the Fort Calhoun Nuclear Station,” Burke said at a briefing in Omaha Mayor Jim Suttle's office.

The nuclear plant, 20 miles north of Omaha, was shut down April 9 for refueling. It has not been restarted because of the imminent flooding.

..........


The article said that the risk of flooding was clearly identified and in June 2010 the authorities had asked for protective measures against this risk.
And nothing has been done.

... Perhaps it's just as well that Fort Calhoun got into trouble last year with federal regulators over flood preparedness. During routine inspections in June 2010, the NRC concluded that deteriorating conditions during catastrophic flooding could make sandbagging near the river difficult.

Regulators required OPPD to improve flood defenses and reported in April that those improvements were taking the plant in the right direction.

......


Regarding the closure of airspace, they say it is to avoid the arrival of small planes and media choppers who would come to take pictures, and traffic could result from an air accident. So they don't want to add that to the current problems. In addition the roads on the ground are closed, which would not facilitate rescue.

Elizabeth Ishan Cory, an officer for the Federal Aviation Administration, said the flight restrictions at Fort Calhoun are intended to keep curiosity seekers out of the immediate vicinity. Planes can still fly near the plant if they have flight plans and are in contact with air traffic controllers. Smaller aircraft are restricted in how close they can get to the plant.

Otherwise, there's a risk of midair collisions that could jeopardize operations on the ground.

“When you keep the area above the ground safe, you're going to keep the people on the ground safe, too,” Cory said.

this other article http://www.globalresearch.ca/index.php? ... &aid=25308

says that the emergency diesel for cooling the core is not flooded because it is raised.

...... Nuclear expert Arnie Gundersen said that he doesn't expect a melt-down, as the diesel generators are situated higher above the ground than at Fukushima, so - unless the water rises further than expected - they should keep working :

At the origin of the facts, a Missouri flood

It all started on June 6, when an alert was launched due to an imminent flood from Missouri. Due to heavy rain added to the snowmelt, the Point Gavins dam, located upstream, had to release a very large amount of water. A wave sweeps over Missouri and floods the surroundings of the power plant. The next day, a fire broke out in the switch room. Toxic fumes cause the evacuation of the plant. Fortunately, the automatic extinguishing system overcomes the fire. However, cables feeding the cooling system pumps were damaged. The plant loses its cooling system for several hours.

Fort Calhoun, a nuclear power plant already pointed out

The Fort Calhoun power station is a power station equipped with a pressurized water reactor. The reactor was shut down in April for refueling. The used fuel is stored in a swimming pool, to complete its cooling (operation which lasts several months, even a year). It probably also contains new fuel, awaiting loading in the reactor.
How is it that this power plant, however renovated in 2006, lost its cooling system following a simple flood? We imagine nuclear power plants equipped with multiple emergency generators and ready to face the elementary risks linked to their position on the water's edge. It would seem that it is not the case… In 2010, the American authority of nuclear safety had published a report indicating that the power station of Fort Calhoun did not have procedures of protection against the floods. A roof!
