The era of confrontation between the capitalist and communist worlds was called the Cold War. Its battles were played out not within the borders of the main participants - the United States and the USSR - but in countries or even regions quite distant from Moscow and Washington

Один МиГ над Тель-Авивом: Как в октябре 1973 года СССР предотвратил Третью мировую войну
Эпоха противостояния капиталистического и коммунистического миров получила название «холодная война». Ее сражения разыгрывались не в границах основных участников - США и СССР, а в странах или даже регионах, весьма отдаленных от Москвы и Вашингтонаzvezdaweekly.ru
There will be no more Chernobyls
How it was possible to blow up the reactor
Anatoly Vasserman, thermal physicist engineer, power engineer (in reserve) of a nuclear submarine
All of the following is taken (and compared) from many different sources. Among them are numerous publications related to the 1986.04.26 disaster, scientific and popular scientific works on nuclear physics and nuclear power engineering, educational materials, my own attempts of analysis, conversations with people much more competent than myself. I could hardly list all these sources, for which I apologize to their authors. Almost inevitable violations of someone's copyright are completely unintentional.
I am also obliged to assure you that none of what follows is secret, not only in fact but also formally.

Go slow.
Exactly at the beginning. Shutting down thermal power equipment is a very slow process. Rapid cooling is difficult to make uniform. And in case of uneven temperature redistribution, thermal deformations can shatter even the most massive structure. That is why, for example, to temporarily reduce the power of a ship turbine unit, steam is sent through a bypass pipeline, past the turbine: it is much faster and safer than switching off the boiler heating.
By the way, heat and power plants are started even slower than they are stopped. And there are special reasons for the slow start-up of nuclear reactors, which are worth talking about later.
So, in the evening, when the load on the power system is reduced, the fourth reactor started to be shut down. They lowered the neutron-absorbing rods a little deeper, and the chain reaction went down.
They waited for the reaction level to stabilize, lowered the rods again - the reaction weakened again... Many dozens of such steps to shutdown should be passed before the reactor is not shattered.
To the rescue
When the power of the reactor had already decreased by almost a third, the Chernobyl NPP received a command from the KievEnergo dispatcher.
The shutdown of units in the power system is as routine as possible. By the time of reactor shutdown at one of KievEnergo's thermal power plants, the boiler and turbine generator were to be started after repair. The starting unit would have taken on the load leaving the broad Chernobyl shoulders.
But repair, unlike manufacturing, is a piece thing. It is not always possible to predict its course. The repairmen were delayed for several hours.
And the dispatcher of Kievenergo asked to bring the reactor back to normal power, so that in these few hours to avoid failure, fraught with increased withdrawal of energy from the all-union system. And in an unfavorable scenario, something would have to be shut down.
Power engineers are disciplined. Working in a unified system, you realize that any mistake you make will affect many thousands of colleagues. So the dispatcher's request was accepted for immediate fulfillment.
The absorbing rods went up. And the acceleration began as smoothly as the previous braking.
The same stairs, but with a clunker.
A few hours later, the thermal power plant started working. KievEnergo reported that the reactor could definitely be shut down.
But the time planned for the experiment was gone. And in the morning, repairs began. The station management decided to accelerate cooling of the reactor to the planned level. After all, the normal rate was set by a considerable margin. The allowable cooling rate had been exceeded more than once before, and everyone knew very well how far it was possible to go without damaging the reactor. Power began to be reduced not in the normal mode, but a little faster - at the very speed, the safety of which had already been verified.
The operators turned off the emergency automation immediately. What if cooling would go even faster and steam supply to the turbine would have to be stopped ahead of schedule?
And so it turned out to be. The power level at which it was planned to stabilize in order to establish a uniform mode in the reactor was rushed through. We wanted to work according to the original plan. Otherwise, we'll still have to recalculate the results - again with an error.
Well, we can warm up again. The control rods went up again. But the reactor power remained reduced.
The station was staffed by experienced power engineers. But the peculiarities of the behavior of nuclear reactors were apparently unfamiliar to many of them. Judging by the fact that the reactor's reluctance to restart surprised many of them. So much so that they simply forgot to turn on the automatic control systems.
Or maybe they deliberately didn't want to. Automatics would not allow them to do something forbidden - extracting the reactor from the iodine pit.
Thermal engineering processes - boiling water, turbine rotation, steam condensation - are not very simple, but they have been studied for centuries. So their smallest details are familiar, if not to every passerby, then at least to every engineer at the power plant. But the chain of events heating fuel elements in a nuclear reactor is much less familiar. Therefore, I will start from the basics - those who know the process as well as I do can safely skip the next few sections (at least up to the section "Someone Loses").

The secret of the success of the Stalinist economy
Economic problems of socialism in the USSR
I.V. Stalin
Well, and then came the Trotskyists, led by Khrushchev, the theory of Convergence, the Kosygin-Lieberman reforms, with dismal attempts to cross the hedgehog with the hedgehog, and the planned economy with self-calculation, when the plan in pieces and units of production began to be replaced by indicators in rubles - and the world's best socialist economy, the rate of growth and development of which no one has ever been able to overcome - sadly and surely came to an end.
And by the way -
mega-corporations, including transnational ones, work exactly the same way - according to socialist, planned methods of economic management. And individual divisions of TNCs do not pay each other in rubles, dollars or other currencies, but only in units of production. And some production units will turn out to be loss-making if they are transferred to self-sufficiency and self-financing. But the sly-ass bourgeois, who tricked the Khrushchev-Trotskyites into Convergence, did not tell them about it.
Well, and the current uneducated dilettantes, advocates of so-called liberal economics, who ruined the USSR in the "holy" 90s, were tricked like suckers - with manetarist theories, the invisible hand of the market, competition and the international division of labor. They forgot to tell the neophyte-school that all this shit hasn't worked for a long time - since the end of the 18th century, approximately. And the methods suitable for Liechtenstein or Burkina Faso are fundamentally unsuitable for ruling a superpower.
Do you know why today's faggots in power so zealously and everywhere install memorials to the so-called "victims of Stalin's repressions"? I didn't get it the first time either. Do you think they really suffer for the sheer number of great human sacrifices? They don't give a fuck a hundred fucking times over - just remember the cannibal quote about 30 extinct millions of those who didn't fit into the market.
Fuck no! All these monuments to the victims of socialist abortion, all these "walls of shit", they put up for themselves - under the sole slogan of inadmissibility of repetition. And they see perfectly well that on the memorial slabs their names are clearly visible through the surnames of these "victims", who are actually enemies of the people. And they are the first in line for the firing cellar.
The damned Communists left you a superpower and the world's second largest economy. Where is it, by the way? And what have you achieved in 30 years? Have you surpassed the Soviets in anything? Except for the presence of dollar billionaires, the number of officials and cops per capita?
You have a government that is an inefficient owner? And it should withdraw from economic management as much as possible. The invisible hand of the market will come and ruin everything by itself, and a kind uncle from the IMF will give money for it - that's your whole fucking paradigm. And the main thing is that you unpleasant bitches, schoolboys and dilettantes, do not know how, cannot and do not want to manage the state entrusted to you by the trusting people.
Everyone knows what happens when some cannot and others do not want to.
