Consult our udpate of April 24,2020


The fires in Ukraine, which had been announced extinguished on April 15, 2020, were reactivated under the effect of strong winds which stirred up the embers of previous fires.

On April 17, 2020, IRSN produced a new information report explaining the evolution of the fires compared to the situation presented on April 15, 2020, and specifying some elements relating to the nuclear installations located on the site of the Chernobyl NPP.

This update also presents a new version of the modeling of the air mass trajectories from the fire area and now covers the period from 3 to 20 April 2020.

The red triangle represents the l​ocation of the fires, the time is in UTC.

The radioactive release used was evaluated by reverse modeling (use of available measurements). This simulation was performed on the assumption that the average radioactive releases, which occurred between April 3 and 12, 2020, will continue from April 14 to 20, 2020.
