Fort Calhoun nuclear plant flooded waters of the Missouri, but U.S. officials insist that there is no danger of a radiation leak ..In Nebraska, where a severe floods, June 27, elements destroyed fences nuclear power "Fort Calhoun."
According to local officials, the water penetrated into the turbine hall NPP "Fort Calhoun", located 30 km from the city of Omaha has a population of 410 thousand people.
NPP staff with emergency services during the week trying to prevent the penetration of water from the Missouri River to the power station.
Earlier, the Associated Press published an aerial plant, which is seen as the water came close to the station and threatened to flood the unit. Despite the photo, Nebraska authorities surrounded the area of nuclear power giant rubber barrier — dike height of 2.5 meters. But she could not hold back a long time coming pressure water — one of the sections of the dam collapsed on the night of June 27.
Currently, the station is no power, cooling the reactor by means of back-up generator, and the employees are trying to restore the nuclear boom and pump out water from inside the turbine hall. NPP buildings are safe in finding water on the mark to 309 meters above sea level. Currently, water is at 306.7 meters and it is expected to not rise above the level of 307.2 meters.
As a result of rising waters in Missouri were also flooded areas around some auxiliary buildings of the power plant. Authorities ordered the evacuation of residents of the neighboring villages.
However, the plant's management emphasizes that "the situation is not dangerous for local residents." The turbine room "does not store any radioactive materials," confirmed an official representative of the power company Omaha Jeff Hanson. "Everything is under control, there was no danger," — he stressed. Hanson added that the NPP "Fort Calhoun" is not in operation since April 2011, in connection with the replacement of spent nuclear fuel. To "Fort Calhoun" operates only one 500-megawatt nuclear reactor. This is the weakest of all of the commercial reactors in North America.
June 7 at the station already flooding occurred, which led to a fire in the plant. The result has been disabled the cooling system and all the staff immediately evacuated. However, the cooling system quickly repaired, but the unit is currently in a state of cold shutdown.
Nuclear power plant, built in 1973, is located on an area of 270 hectares near the same city and locality Blair on the Missouri River.
On June 28 flooded the station comes to the inspection head of the Nuclear Regulatory Commission, Gregory Yatsko USA. He will also hold consultations with the NPP Fort Calhoun, to find out what efforts are required to prevent a larger flooding station. Chairman of the NRC has already visited another facility in Nebraska, who was in a "water captivity" — NPP "Cooper." As a result of the inspection Jacko said the situation at the nuclear power plant, "Cooper" did not raise any concerns.
The main cause of severe flooding on the Missouri River — the largest tributary of the Mississippi — have spring rains, which have failed drains. As a result, the water went into the basin. According to the forecasts of meteorologists, flood situation in the basin of Missouri will continue until mid-July. The level of water in the river will remain high until the end of summer.
Suffer from severe flooding residents of several states. The hardest hit have people in North Dakota. Fled their homes 11 thousand. Damaged more than four thousand buildings. The water all the time arrives.
Weeks of heavy rains and a large drain after an unusually snowy winter led to a flood of the Mississippi River in May, has suffered a number of states, the water flooded 1.2 million hectares of farmland in Mississippi, Tennessee and Arkansas. Then, the river burst its banks Missouri. At the moment, is expected to increase the level of flooding in the neighboring state of Nebraska and Iowa. Flooding will be held, probably in August in connection with the spring heavy rains in the highlands of the Rocky Mountain, where melting snow and water poured into the river.
