“Shelter” at the Chernobyl nuclear power plant will withstand a six-point earthquake

20 Apr

The nuclear power plant can withstand an earthquake of magnitude 6 thanks conducted in 1997 and 2008 projects to enhance security and stabilization facility, told the CEO Igor Gramotkin station.
“Currently, facility due to the work carried out is in stable condition for 15 years. Looking at this angle,” Fukushima “, we were able to bring it today in a state where it can withstand an earthquake measuring 6 points without the destruction and consequences”, – said he said.
Events dedicated to the 25th anniversary of the Chernobyl disaster, will be held in Kiev from 19 to 22 April, and chief among them will be the holding of the Chernobyl Pledging Conference, the result of which the Ukrainian authorities are hoping to collect the missing 740 million euros for the construction of the Shelter at the Chornobyl NPP.

The disaster at the Ukrainian Chernobyl nuclear power plant occurred on 26 April 1986, when the fourth power station exploded. As a result, the territory within a radius of 30 kilometers was subjected to radioactive contamination from radioactive contamination affected 19 Russian regions with an area of ​​almost 60,000 square kilometers and a population of 2.6 million people, 46,5 thousand square kilometers in Belarus (23% of the total area). The total area of radioactive contamination in Ukraine amounted to 50 thousand square kilometers in 12 areas.
After an accident on the fourth block of Chernobyl sarcophagus was built, which in recent years is gradually being destroyed. Ukraine is working on the construction of a new safe confinement (protective equipment) “Shelter” on the fourth block, which is designed for 100 years to ensure the safety of the object. For this project to date, Ukraine lacks 740 million euros.
In general, the implementation of the Shelter to about 1,6 billion euros.
The Chernobyl nuclear power plant was shut down on Dec. 15, 2000. Country’s “Big Seven”, who demanded the closure of Chernobyl and promised money for the shelter, still have not fulfilled their promises.
Guaranteed safe condition of the old sarcophagus over the fourth power unit of Chernobyl nuclear power plant is 30 years old, that is, approximately five years it may become ineligible for the “containment” of the release of radioactive substances from the damaged reactor. In this regard, the issue of building a new shelter over the damaged reactor is becoming increasingly important.
The Shelter will be a building in the form of an arch 105 meters, 150 meters long and a width of 260 meters. After construction it will be “slid over on the fourth block of Chernobyl, on which after the 1986 accident was constructed sarcophagus.
Safe use of nuclear energy has become the focus of global attention after an earthquake on March 11 in Japan and the subsequent accidents at Japanese nuclear power plants, in particular, “Fukushima-1. Thus, in some countries, programs to develop peaceful nuclear energy are under threat of closure. German authorities have decided to suspend the old reactors, and also suggested a European common security standards for nuclear power plants.
Switzerland has also decided to suspend the process of updating its nuclear reactors. Of the first countries in the Western Hemisphere agreed to freeze the program of peaceful nuclear energy in the zone of seismic activity Venezuela. However, the majority states, particularly the U.S., China and Russia, as well as being one of the world leaders in nuclear energy France, said that is not going to abandon nuclear energy.
Other European countries have announced their intention to test the safety of all nuclear power plants in the country to draw lessons from the accident at Japan’s “Fukushima-1, however, are not going to abandon the peaceful atom.
Ukraine also intends to significantly revise its energy strategy, which involves construction of nine new reactors at existing nuclear power plants in coming years. According to experts, the rejection of nuclear energy and switching to alternative heat and hydroelectric power will lead to deterioration of ecological situation in the country. In addition, following the closure, we can expect a significant decline in industrial production, which depends largely on the use of cheap electricity generated by nuclear power plants.
