Did Pressing AZ-5 Twice Doom Chernobyl?

It is a little known fact that the Scala computer system operates with a 1 second delay, the ticker corresponding to the computer system does not mean that the infamous 12340 moment when the az5 button was pressed is incorrect, the computers actually recorded it in 12339 but this is not the topic of today's video, our subject remains focused on the data recorded around this time and subtle data entry 2 seconds later at 12341 a second AZ signal is recorded, however the last number was lost due to the power outage that occurred. when the reactor exploded, this begs the question: was the az5 button pressed a second time?

If so, why today we will explore another Chernobyl mystery? By double

pressing

az5 we start as we often do with evidence and again there is not much to exploit. other than the magnetic ticker and we still cannot say with certainty that it is an AZ 5 signal. There are a total of six azed signals that can be broadcast but of course some of them can only occur in certain situations , az4, for example. is a placeholder for an emergency signal that might have been needed in the future. The same applies to several other signals until we are left with three activations of az1 az2 and az5 az1 after the disconnection of one of the six main circulation pumps or a decrease in power. water while az2 is activated when a turbogenerator is disconnected from the reactor.

Now, how do we decide which signal was most likely activated here? Well, we can quickly remove az2 since the turbine had not been disconnected from the reactor system, so we focused our attention on az1 az1. It is only activated when a pump is disconnected, however, at the time when az5 was pressed there is some uncertainty as to whether the pumps would have been disconnected, the flow is too high according to Alexi Fatov, former senior reactor control engineer of the unit. 3, can also be seen in these Graphs when the pressure in the reactor reached a critical point that closes the reflux valves as the flow rate from the pumps drops dramatically and then rebounds when the upper biological shield is ejected, according to one of the Chernobyl's most respected and recognized engineers. the event that occurred has to be an az5 signal this is very interesting and of course the question is why there are several reasons why this could happen so let's take a look at them so fatov has his own particular theory as to why the button could have been deliberately pressed once and to understand this we need to take a look at the behavior of the monolith that is the rbmk reactor these reactors have a series of 12 automatic regulators that are controlled by computers to keep the power stable during the last 6 seconds of the En In summary we can see the insertion of all these automatic control bars according to the surviving data recovered after the explosion.

A very unique clause in the operation manual requires a reduction of power in case of such a situation, an insertion of the automatic control rods at a certain speed. The FOV theory is similar to Topov pushing the button to 5 when he saw these control rods lower not to shut down the reactor but simply to slow it down. I personally disagree for a couple of reasons, one from the night of the disaster and one from today, according to Witnesses like Diatlov and Davetv Topov asked Akimov a question to which Akimov responded with a finger tapping motion. What was said directly in this brief exchange has been completely lost, never recorded, but what we do know is that based on the information above Akimov was also an expert on turbines and not reactors, it is much more likely that Akimov would have ordered a complete shutdown instead of a power reduction and, furthermore, he did not know that the reactor should have been shut down at the beginning of the test.

The automatic regulators were going down, so why would he give the order to simply reduce power now? If this is really an az5 signal, my theory for why it would be like this, we'll have to go to the real world for a second, as you can see. it has a button of the same type of model used for the azed 5 a ke11 button now this button does not look like the real az5 since it uses a different cover, a metal one, but the button under the cover does not change if there is something I have Noticed how sensitive it is when I just play with the button, if you didn't know that the bottom of the button uses these metal pieces here to connect the current, but it is very precise, you have to hold the button completely in order to activate the signal By the way, it also makes a nightly clicking sound, but anyway, getting back to the button, it's very easy to accidentally weaken your grip and therefore disconnect it.

You can even hear the little clicking sound again when I do it, I personally think. Something similar happened here. Topov accidentally momentarily weakened his grip on the az5 button, which stopped the signal transmission and then stopped the movement of the control rods, perhaps for up to 2 seconds, of course, at this point, reactor power had begun. to run amok. and so topov would naturally have pressed more firmly reestablishing the signal, the theory follows that if the control rods were still descending, enough graphite would have been pushed through the bottom of the reactor in those two seconds to stop the increase in power, thus saving on the reactor, of course, there would be the possibility of suffering some damage, naturally a channel rupture due to pressure, for example, but the reactor would have survived.

Such a scenario would probably have been swept under the rug, with Diatlov Topov and Aov probably losing their jobs or receiving some other kind of major disciplinary action, but Chernobyl today would probably be remembered for being a very large nuclear power plant and who knows what it was about. I would try this YouTube channel, of course, the question is if this is the case, did two seconds make the ultimate difference? being 0.8 M of graphite in each control rod, the answer probably does not lie in the end-of-day calculations that demonstrate the physics of the reactor in those last seconds, such as those in Helman Chuk's work, assuming that the control rods They are completely descending all the time. eight seconds or so between the initial press of the az5 and the explosion, so unlike what proponents of this theory seem to suggest, it doesn't matter whether the az5 button was pressed

twice

or not, there simply isn't enough time to input enough boron in the core to stop water becomes a critical point when the control rods are fully inserted.

The lower 40 cm of the reactor is occupied by graphite in the control rod channels; however, for the top 80 cm of the section where the leak began an additional 10 cm would be needed. seconds for the graphite to have left the area and another three before the Bor even began to enter, that is, at least 13 seconds of uncontrolled rapid criticality at the bottom of the reactor no matter what, with a maximum of 8 seconds of insertion. It just won't matter, not with the positive vacuum coefficient of course, the control rods will be inserted a third of the way, as seen by many people in the control room that night, like anat diov, and in the morning people like Victor smagin. suggest that the control rods moved for the full 8 seconds, as it takes approximately 24 seconds for the rods to fully descend.

We should expect to see them only a quarter of the way inserted before the wires transmitting the signal are vaporized well with a double squeeze. situation with only 6 seconds to move maybe fatov was wrong who knows regardless of his opinion on the matter the soviets certainly had some agreements with the notion of double pressure and all the uncertainty with the signals to prevent anyone who accidentally let go For example, they replaced the az5 button in 1987 with the switch we all know today there is no risk of accidentally stopping the az5 signal and with current modernizations there is no chance of another rbmk exploding, sleep tight I guess, good night to all.
