What events lead to the accident in chernobyl?

The Chernobyl accident on April 26, 1986, was primarily caused by a flawed reactor design and serious operational mistakes during a safety test. Operators at the Chernobyl Nuclear Power Plant attempted to conduct a test to assess the ability of the reactor to provide power during a grid failure, but they ignored safety protocols and overlooked critical warnings. A sudden power surge occurred, leading to a series of explosions that ruptured the reactor core, releasing a massive amount of radioactive material into the atmosphere. The combination of design flaws, inadequate safety culture, and human error culminated in one of the worst nuclear disasters in history.
