The Soviet government initially attempted to downplay the severity of the disaster. However, as the extent of the damage became clear, a commission was established to investigate the causes of the accident. The commission's report identified a combination of design flaws, operator errors, and inadequate safety procedures as contributing factors.
However, the test was poorly designed and executed. At 1:23 a.m. on April 26, the reactor power began to increase rapidly, and the operators, attempting to reduce the power, made a critical mistake: they withdrew too many control rods, causing the reaction to surge out of control. A massive power excursion followed, and at 1:24 a.m., a steam explosion occurred, rupturing the reactor vessel and releasing a large amount of radioactive material into the environment.

In the 1970s and 1980s, the Soviet Union embarked on an ambitious nuclear energy program, aiming to increase electricity production and meet growing energy demands. The Chernobyl Nuclear Power Plant, commissioned in 1977, was one of the largest and most modern nuclear facilities in the Soviet Union at the time. The plant consisted of four RBMK (Reaktor Bolshoy Moshchnosty Kanalny) reactors, designed to generate 1,000 megawatts of electricity each. The Soviet government initially attempted to downplay the
On the night of April 25, 1986, a maintenance shutdown was scheduled for Reactor 4. To ensure a safe shutdown, operators decided to perform a test to determine how long the turbines would keep spinning and generating electricity in the event of a loss of power to the main cooling pumps. The test aimed to buy time for the emergency core cooling system to activate. However, the test was poorly designed and executed
