On the night of April twenty-six, a terrible explosion occurred at the fourth power unit of the Chernobyl nuclear power plant. The first victims are two substation workers. The final number of victims of this tragedy is unlikely to ever be announced. The reasons for the terrible tragedy are still theories.
Theory number 1. Human factor
Immediately after the accident, the station leaders and managers were the first to blame. Such a conclusion was previously given by a special state commission of the USSR. Such an assumption was also made at the IAEA. The Advisory Committee, guided by materials provided by the USSR, also concluded that the accident was the result of the coincidence of various violations of the rules for the operation of the station by working personnel, which is unlikely.
Such a massive catastrophic consequences of the accident acquired due to personnel errors. For the same reasons, the reactor was transferred to an emergency mode. According to experts of the created committee, all these gross violations in the operating rules of the station consisted in conducting the necessary tests at any cost. And this, despite the fact that the state of the reactor has changed. Technological defenses that could simply stop the operation of the entire reactor were not launched on time, and the scale of the disaster in the first days after the explosion was hushed up.
Theory number 2. Deficiencies in the design of a nuclear reactor
In the USSR, after several years, they still changed their minds to blame only the personnel of the NPP for everything that had happened. The Special Atomic Oversight Commission of the Soviet Union came to the conclusion that the accident itself nevertheless occurred due to the fault of the personnel. But it acquired such catastrophic proportions only because of malfunctions in the design of the reactor of the nuclear power plant, its shortcomings.
The IAEA also had this opinion, only after a couple of years. They published their view of the accident in a special report. It is also presented here that the main cause was errors in the design of the reactor and its design. Mistakes in the work of the staff here were also voiced, but as an additional factor. The report indicates that the main mistake was that the workers still maintained the operation of the reactor in a dangerous mode.
