At the Chernobyl nuclear plant in 1986, in fact, was not thermal, but a small nuclear explosion capacity of about 75 tons of TNT. Write about this Swedish scientists in the article, which was published in the journal Nuclear Technology.

The result of a failed experiment on the station earlier in the night of 26 April 1986, the reactor power jumped from 0.2 to 320 gigawatts, followed by the explosive destruction of the shell of the core. As the authors of the material, most of the witnesses speak of two powerful explosions.

The classic version of events explains the first explosion because the water from the cooling system evaporated and destroyed pipe, then got on extremely hot zirconium cladding of Fuel rods. The result was the hydrogen that exploded in the interaction with oxygen. A group of Swedish scientists questioned the fact that the explosion – the first was heat. They write that in fact it was a miniature nuclear explosion.

Scientists say that after a few days after the accident, Soviet physics, noted the abnormal activity of the isotopes xenon-133 in the liquid xenon, which was received at the factory for the liquefaction of air in Cherepovets (about 1 thousand km from Chernobyl). The ratio of activities of isotope 133Xe / 133mXe made up to the hour of the day 29 APR approx 44.5 ± 5.5 in.

Computer simulation on the program Xebate have shown that with high probability the result of the leak it was after a nuclear explosion.

In addition, the Swedes conducted a simulation of weather conditions in those days, using a new three-dimensional climate data and advanced algorithms calculate the movements of air masses. We performed a simulation of the dispersion of xenon isotopes for 17 different heights of the emission is from zero to 8 km.

It became clear that recorded in Cherepovets activity levels of xenon isotopes are explained by the assumption that radionuclides emitted rose to a height of about 3 km and a height of emissions, analysts say, could provide 75-ton TNT equivalent nuclear explosion referred to in the study.

In favor of their hypothesis, the scientists cite several circumstantial evidence, which can be read in the publication.

“The script is confirmed by the destruction of the lower cover of the reactor block (a two-meter plate of the serpentine in the iron shell of the South-East quadrant of the reactor core, – ed.), seismic detection (including sound) at about 100 km from the reactor and witnesses about the blue glow a few seconds after the first explosion, which can not be explained in any other process than a nuclear explosion,” concluded the researchers.
