Chernobyl

target: Checking the operation of the turbine generator when the reactor is switched to low-power mode overnight: During tests of turbine generator No. 8 at power unit No. 4 of the Chernobyl nuclear power plant on the night of 25-26 April 1986, an explosion occurred, destroying the reactor. It was at 01:23:47 Moscow time. Tests were to be conducted at 700-1000 MW, which was 22-31% of the reactor's full capacity. condition: The reactor was shut down and the emergency cooling system was switched off.

Perevoshchenko (standing above the reactor lid when the tips rise there, run to the control room to notify the staff

where there are a lot of pipes there is a room below the reactor where after the explosion there will be an elephant's foot after the explosion and before the explosion it is just a room with pipes and a sealed door

separators are needed to dry the steam and to keep the steam dry and not to harm the rotor, because if wet steam gets in, then the rotor can rust because of this, for more efficiency, separators are used (probably)

reactor type RBMK-1000 in their time this type of reactor is unsafe and if you lift the rods from the fuel and graphite core then an uncontrolled chain reaction process and Dyatlov ordered to raise the rods up completely to remove the reactor from poisoning (xenon or iodine pit)

pumps are needed to maintain water circulation, steam circulation so that steam or warm water goes away, if they are turned off, the reactor will heat up from possibly steam or warm water

Victor Bryukhanov (Director of the Chernobyl Nuclear Power Plant)

Nikolay Fomin (Deputy Director)

Anatoly Dyatlov (deputy and then maybe director if the tests are successful)

Valery Legasov (Kurchatov Institute Legasov was called to eliminate the accident at the Chernobyl Nuclear Power Plant)

Boris Shcherbina (if you count in the HBO, he was stubborn, but Legasov was able to persuade him, and because of this Shcherbina saw what actually happened, it was not a tank explosion, it was a reactor)

the turbine hall is a multi-kilometer hall where the turbine hall connects 1, 2 and 3, 4 reactors 1 and 2 are simple reactors without additional systems, only the reactor hall itself, but 3 and 4 are surrounded by separator pumps and between 3 and 4 there is a cooling tower (a familiar cooling tower) turbines are needed to rotate the rotor and generate energy

Alexander Akimov (reactor controller)

Leonid Toptunov (reactor controller Toptunov inexperienced 2 months of work or a little more)

Boris Stolyarchuk (controller of reactor circulation pumps)

Igor Kirshenbaum (HBO character controlling turbines)

Anatoly Dyatlov: chief testing engineer (usually angry but sometimes kind, wants to go to the deputy director after the tests and then to the director after the tests)

Alexander Kudryavtsev and Proshkuryakov (people who can replace in case)

trigub (from the documentary, he replaced Toptunov for disobedience in carrying out work. Toptunov persuaded Dyatlov to leave the reactor alone, but Dyatlov wanted the test to continue Akimov also couldn't hold back and tried to warn Dyatlov, but Dyatlov didn't need it)

Victor Degtyarenko (pump operator)

Valeriy Khodemchuk (Senior Circulation Pump Operator)

Alexander Yuvchenko (usually in his office)

Gorbachenko (dosimetrist)

Shashenok (was sitting in the office where the pipes were after the explosion, he was seriously injured and died in the morning)

This is the Chernobyl nuclear power plant named after Ilyich Lenin (communism 1986) the station has a RBMK-1000 reactor (unstable) Chernobyl had 4 power units 5 and 6 were not the main unfinished ones after the accident the first 2 reactors were closer to the admin building but the hall structure itself was between them 1 simple cooling tower but the reactor itself was small because all that was visible there was the reactor and nothing around except for turbines, the same goes for 2 reactors, but 3 and 4 are better 3 and 4 are surrounded by mechanisms and devices to improve the operation of the reactor between 3 and 4 is the famous cooling tower as well as 3 and 4 power units

[turbines]:? [slow/steady/fast/stop rotation] pumps: 1: on/off 2: on/off 3: on/off (pumps are needed to circulate the reactor and steam) [indicators]:? (like low power or low temperature, but it didn't indicate what was happening inside the reactor) [cooling system]: on/off

Dyatlov was not kind to his subordinates with the experiment began Dyatlov said to reduce the power to 700 MW but Alexander Akimov and Leonid Toptunov reduced it for a very long time but later the power began to fall by itself it turned out there was Xenon or Iodine Pit or reactor shutdown Leonid and Akimov tried to persuade Dyatlov to turn off the reactor but Dyatlov didn't want to Leonid Toptunov little working station for about 2 months when Dyatlov ordered to raise the rods to bring out the power Akimov and Toptunov raised the rods but a reaction began to occur in the reactor core but the instruments were silent nobody knew what was happening there in the reactor part the power was growing but nobody knew at all and the power started to grow very quickly because Toptunov and Akimov brought the rods to the maximum and that is not allowed and who said to raise the rods correctly Dyatlov from this the reactor started the process of self-sustaining chain reaction when the reaction does not react at all to the rods and accelerates the reaction there in the rods the control tips were graphite and when Akimov pressed on AZ-5 everything started to fall but because of the graphite core it created more power because of this the rods from the pressure rose back into Khodemchuk it was heard that the pressure in the pipes was higher than normal and possibly a rupture in the circuit of the circulation pump releasing steam 1 explosion was in the active zone of the reactor part of the active zone was blown up and later an explosion lifting the lid or "scheme E" throwing the reactor lid where-tt approximately 1000 tons + into the air
