Scientists from the Russian Federation demonstrated a material that will protect against the consequences of the accident at the Fukushima nuclear power plant.
MOSCOW, 17 July/ Radio Sputnik. Scientists from the Research Technological Institute, AP Alexandrova (NITI) showed Journalists of the “Zvezda” television channel, “victim material” developed to prevent the consequences of leaks at nuclear power plants.
“Such disastrous results could have been avoided if there were devices for melt localization under the reactors in these units (at the Japanese nuclear power plant Fukushima-1,” Ed.). This is an ingot and concrete obtained at our plants, Vyacheslav Almyashev, head of the NITI Severe Accident Investigation Department “Our model had a melting zone on it. And we see the result of the concrete interacting with the melt,” he said.
The properties of the material were tested in the laboratory by recreating the “little Chernobyl”. At a temperature of about 2,500 degrees Celsius, scientists studied the interaction of the melt with various materials.
In March 2011, after the largest magnitude 9 earthquake, a huge tsunami wave hit northeast Japan up to 15 meters high.
It flooded the power supply system of the Fukushima-1 nuclear power plant and disabled the reactor cooling system.
During the accident, hydrogen explosions occurred in the first, third and fourth reactors. A protective dome was placed over the power unit to prevent the release of radionuclides.
The accident at the station was recognized as the largest after the accident at the Chernobyl nuclear power plant.
After decontamination, residents of surrounding houses were allowed to return to their homes. However, some areas are still uninhabitable.
According to the estimates of TERSO, the operator of the Fukushima-1 nuclear power plant, it may take up to 40 years for the consequences of the accident to be finally eliminated.
Considering the losses, 22.2 thousand people became victims of natural disasters.
In March, Sputnik radio reported why a fire alarm went off at the Fukushima-1 nuclear power plant.
