Detailed explanation-1: -The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the environment, with the deposition of radioactive materials in many parts of Europe.

Detailed explanation-2: -The RBMK reactor design was poor from the point of view of safety and unforgiving for the operators, both of which provoked a dangerous operating state. The operators were not informed of this and were not aware that the test performed could have brought the reactor into an explosive condition.

Detailed explanation-3: -Automation Would Have Prevented the Accident The answer is simple: An automatic safety interlock would have prevented the start of the test until the 700 MWt limit was reached. Unfortunately, automatic safety interlocks can prevent accidents only if they exist and can’t be deactivated by the operators.

Detailed explanation-4: -The Soviet government ordered the operators of Chernobyl to perform a test on their reactor. The test was supposed to measure how long the spinning generator would continue producing electricity after the reactor was shut down before it slowed and stopped. The test was to happen with the reactor at low power.
