On the night of April 26, 1986, the turbine generator was tested at the 4th power unit of the Chernobyl NPP.
It was planned to stop the reactor (the emergency cooling system was switched off as planned) and measure the generator parameters.
It was not possible to safely shut down the reactor. At 1: 23 a.m. Moscow time, an explosion and fire occurred at the power unit. The emergency was the largest disaster in the history of nuclear power: the reactor core was completely destroyed, the power unit building partially collapsed, and there was a significant release of radioactive materials into the environment
