Scientists from the Ukrainian Hydrometeorological Institute of the State Emergency Service of Ukraine and the National Academy of Sciences of Ukraine conducted a simulation that showed the transfer of radioactive impurities in the event of an accident at the Zaporozhye nuclear power plant. The simulation was carried out in weather conditions that were observed on August 15-18.

It is noted that radioactive releases were given in the form of two point sources at heights of 200 and 500 m above the earth's surface with a total stationary power of 1 Bq/s (0.5 Bq/s for each of the sources).

“For radioactive aerosols, the characteristics of their size distribution were used: average diameter 1 µm, standard deviation 2 µm,” the report says..

The researchers note that due to the impossibility of determining the exact characteristics of the source of emissions from a hypothetical accident at the ZNPP, the simulation results should be interpreted only qualitatively and relatively..

Modeling showed that under weather conditions on August 15-18, the highest concentration of radioactive aerosols would be observed within the territory of Ukraine, especially in the zone closest to the ZNPP with a radius of 50-100 kilometers, in all directions from the station. Significant concentrations of radionuclides can reach Kyiv.

“Partly radioactive impurities can also be carried to the territory of neighboring states (eastern part of Belarus, Poland, the Baltic countries). At the end of the modeled period, the main direction of radionuclide transfer is east, as a result of which significant concentrations of radioactive aerosols can be observed over the occupied parts of the Donetsk and Lugansk regions,"

As previously reported, the situation in Energodar, temporarily occupied by the Russian Federation, is dangerous due to the constant shelling of the territory of the Zaporozhye NPP by the Russian troops.. The Ukrainian authorities are developing an evacuation plan from the city and the zone of risk of radiation contamination in the event of an accident at the ZNPP, taking into account the military situation.

Why technically switching the Zaporizhzhya nuclear power plant to the Russian energy system is a very difficult technical task, but not only technical surprises and problems await the occupiers, read in the article by Nikolai Tesli for ZN. UA - Crisis at ZNPP: will blind pilots decide it?
