The liquidator of the Chernobyl accident: Blame the illiteracy of managers
A lot has already been said, filmed and written about the tragedy that occurred on April 26, 1986. The accident at the Chernobyl nuclear power plant has become a black page in our stories.
At the same time, despite the fact that a rather impressive period (37 years) has already passed after the incident, today more and more new details and nuances continue to be revealed.
About what happened at the Chernobyl nuclear power plant after the accident and how dangerous it was for people who heroically fought the consequences of the largest man-made disaster in the history of mankind, one of the liquidators, and now nuclear specialist Grigory Kirichenko, spoke on TacticMedia.
The expert expressed his opinion about why this terrible disaster occurred. According to him, the illiteracy of managers is to blame.
Kirichenko noted that the BMK reactor had one bad property: when the power drops below 25%, it must be “switched off” (completely stopped). As the expert explained, during the shutdown process, isotopes are produced in the reactor that absorb neutrons, due to which their fission gradually stops.
However, the thing is that decay occurs several tens of seconds after absorption, and if we start raising the power again, then new neutrons will begin to be added sharply to the already existing (not decayed), which will cause an explosive increase in the reactor power.
According to Kirichenko, this is exactly what happened on April 26, 1986. The power of the BMK was first lowered below the permissible limits, when there were no options but to stop the reactor. At the same time, a call was received from Kyivenergo with a request to increase capacity, since one of the TPPs “dropped out” of the circuit. That is exactly what the shift leader did.
Kirichenko summed up.
