What caused the Chernobyl Nuclear Disaster?

The Chernobyl nuclear accident happened in April, 1986 and it is considered as the world’s worst nuclear power plant disaster. The incident at Chernobyl was caused by explosions at the Soviet power plant, this caused the sudden surge of radioactive clouds across most of northern Europe. The incident began on Saturday the 26th of April at 1:24 a.m. when Unit 4 of the Chernobyl Nuclear Power Plant (which was about 112 kilometers outside of the Kiev, the Ukrainian capital) was rocked by two enormous explosions. The roof of the plant was instantly blown off and radioactive materials and gasses were sent more than 800 meters into the atmosphere. Although two plant workers were killed instantly in the blast, no official announcement about the hazardous blast had been made. It was two days later on the 28th of April, when Swedish officials had detected an enormous increase in the wind-born radiation levels, also on this day, news of the incident had been briefly reported by the Soviet news agency Tass.

Over the following months, details had emerged that the explosions had been caused by an unauthorized test, which was carried out by the plant operators who were trying to determine the outcome of what would happen in the even of a power outage. However 6 critical errors were made by the workers during the test, resulting in the explosion.
