Biography
After the Chernobyl disaster, he was part of the three-man "suicide squad" that drained the steam suppression pools under the fourth reactor building, since he was very familiar with the layout of the building. Although his feat was quickly forgotten in the wake of the disaster, he was awarded the Order for Courage in 2018 and the title Hero of Ukraine in 2019.

Despite media reports claiming the three men died of radiation poisoning shortly after the incident, he survived and lives in Kyiv as of 2019.
