What were the steps to the chernobyl disaster?

The Chernobyl disaster occurred on April 26, 1986, during a safety test at Reactor No. 4 of the Chernobyl Nuclear Power Plant in Ukraine. Operators conducted an experiment that involved shutting down safety systems, leading to an unstable reactor state. A sudden power surge caused a series of explosions, releasing a massive amount of radioactive material into the atmosphere. Poor reactor design, inadequate training, and a lack of safety protocols contributed to the disaster's severity and its catastrophic consequences.
