This video, although accurate in its details is very misleading. The video makes it sound like there was a nuclear explosion at Chernobyl. It was a steam explosion. There was no nuclear explosion. There can not be a nuclear explosion at a commercial nuclear power plant. The physics of the fuel and the configuration and enrichment of the fuel make it impossible. My intent is not to downplay the severity of the disaster in any way. But facts are facts, there was no nuclear explosion at Chernobyl.
+Simon Smith what do you mean by "steam explosion"?
+SputzNiz Games The reactor went from 300MW thermal to as high as 30,000 MW Thermal (10X maximum power) in seconds. The water in the reactor instantly flashed to steam at a higher pressure than the reactor was designed to contain. Just like a boiler explosion on an old railroad locomotive. A steam explosion is what blew apart the reactor and reactor building.
+Simon Smith I agree Simon, but think about it: Due to Steam or whatever reason, we did expose Uranium to the environment, isn't it?
Its the nuclear component that was damaging, and not the steam itself, so its better if people don't get misled themselves, and better to use "nuclear explosion".
Otherwise, anyone knowing basic science will understand from this video, no doubt, because I'm myself a Commerce Post Graduate, and not a science student.
***** Thanks for the comment. You're of course right, the method that radioactivity is spread into the environment is less important that the fact that it is being spread. My point is that a nuclear bomb explosion is much more powerful than anything a power plant can do during failure. If Chernobyl was a nuclear explosion, the damage would have been far more widespread and the shock wave would have knocked down the other 3 reactors with much more dire consequences. I draw the line at "Nuclear Explosion". It was an explosion at a Nuclear Power Plant (by steam or hydrogen), not a Nuclear Explosion.
Hmm... Thinking that way, yeah, you're right that a "nuclear explosion" would be a wrong description.
Personally, I do hope we never get to witness a nuclear explosion, no matter where in the world. No one deserves it, no matter what they did. And of course, no one is anyone's judge to leash out such a punishment...
That's easily one of the most overly simplistic (overly simplistic to the point of being useless) explanations for the disaster I've seen.

They have missed many facts about this event. The test was delayed by at least 10 hours, the night crew weren't aware nor trained good enough to complete the test at all, the test had failed four times (the fourth one being the explosion), many instructions weren't overly clear, the power dropped close to zero, the graphite tips only made the reaction in the core way worse. The first sarcophagus lasted about 30 ish years (probably not the exact number) the second one was added when a turbine hall roof collapsed.
Many key points and facts were skipped completely or glossed over, which is sad since information about it isn't hard to come by.

@@alybhanvadia1860 ive just started looking into this an hour ago and ive been through many sources of the same story including wikipedia, and this is missing lots.
Yeah they dumbed it down alot for the general people to understand things and not make it hard for them. I mean a RBMK reactor doesn't suddenly drop in power or surge in power. Things happened that they didn't even explain here like the Xenon poisoning effect which is massively important to explain!
They basically said „the reactor exploded” and then proceeded to talk about the Sarcophagus.

I think the fact that this mess was running until the year 2000 is the most amazing and horrifying thing about Chernobyl.
and until then reactor 2 caught fire as well and then reactor 1 broke down. can't wait till ukraine decides to restart reactor 3
After the accident all 3 reactors were restarted. In 1991 unit 2 had a fire in the turbine hall and the reactor was closed, unit 1 was closed shortly after, and unit 3 was shut down in 2000
russians are so fucked in the head.
If you have a energy shortage, you would have to keep it running, after you have completed a new power plant with the same capacity, then you can shut it down.
@@druidofthefang in soviet Russia u don't shut down a reactor just coz a part of it get blown up
This is correct, as far as it goes. There is no depth, however, to explain why it happened.
When they say "cooling water has to be supplied", they don't explain that the fuel rods are creating HUGE amounts of heat when operating (fission is happening in the supercritical regime of the reactivity curve), and there are a lot of them in the reactor of this size. In more-or-less equivalent reactors, the pumps are huge - they have to be to supply 25,000 gallons of cold water per minute to draw off all the heat created. Generally these huge pumps are powered by a significant portion of the electrical output of the reactor. When a reactor goes into emergency shutdown, it stops producing a large part off its heat, and the power generating turbines which convert the heat into electricity immediately start winding down, but the pumps have to still run, as decay heat has to still be cooled to prevent meltdown. The Chernobyl test was designed to answer the question, "If we shutdown the reactor in an emergency, will the spinning down turbines, powered only by their own inertia, provide enough energy to keep the pumps running until diesel generators can take over, in a matter of about 45-60 seconds?" The expected answer from Moscow was, "They'd better, or heads will roll."
The test, previously failed twice on #3, was to simulate a shutdown by shutting off the turbine steam feed to the generators as if the reactor had shutdown and see if they could power the pumps for 60 seconds or so. The reactor was supposed to be at a low but stable power regime, but it was allowed to drop below that for a while, into an unstable regime in which xenon-135 accumulated. This is a fission product, 6.3% by weight of all such products, which has a huge appetite for neutrons; that shuts reactors down, willy-nilly, and was first discovered with the very first reactor, the CP-1, in Chicago during the war. Absorbing a neutron converts it into Xe-136, which refuses neutrons. Most of the Xenon comes from decay of iodine-135, with a 6 hour average delay. Thus, the xenon poison will self-correct in 6 hours or so, so waiting will cure the problem. The other thing that can be done is to feed it massive mounts of neutrons, causing it to "burn" into the less offensive Xe-136, by forcibly increasing fission rates in the face of the poisoning. This is inherently dangerous, because as the Xenon is converted, that in itself increases the fission rate in a positive feedback loop. This is exactly what happened at Chernobyl, when they withdrew control rods to raise the reactivity and force the poisoning to dissipate. It did all right, and the fissioning increased so rapidly that it created instant steam in spite of the reactor's high pressure, in just a few seconds. It was more pressure than the pressure vessel was designed to take, the resulting steam explosion blew the multi-ton cap off the reactor and destroyed the core and almost all the cooling systems.
Some features of the design of the reactor made the results more likely, but the real cause was allowing the reactor to drop below safe power levels and then lack of understanding why that was inherently unsafe. Operators were apparently instructed in the test procedure not to let the drop happen, but why it should not be allowed was considered a state secret, because it almost demolished another plant some years earlier, and Soviet superiority could not be called into question in technology or science. The accident was caused by operation crew ignorance, overwhelming politicization and security, and design flaws.
Outstanding sir. Your knowledge and grasp of the tragedy at Chernobyl are apparent
Design flaw, 100%. If it explodes at X, and the graphite rod tips will cause a temperature spike of Y, then the maximum temperature level is (X - Y), not X.
i appreciate your efforts
The fact the rbmk had a positive void coefficient was really bad.
Very clear and thorough dissection of the incident, very much better than the video explanation.
Did you REALLY push the AZ-5 button ??
Yes, i saw it in interview of Dyatlov
The AZ-5 button made the situation worse.
The az-5 button closes the rods which had graphite on the tips which made the reaction worse

In the game Sim City, one of the disasters that can happen is a nuclear meltdown. When I first played it, I was too young to really know what a meltdown was, but if it happens or if you activate the disaster in the game you can see it. It sure looked and sounded scary in the game. The screen would shake, alarms would go off and there’d be this terrible rumbling. I remember hoping a meltdown wouldn’t happen in real life, because I at least knew it seemed horrible.
which sim city
@@Walter.609 I think it was SimCity classic. I played it on a big old computer, a Windows, I think. I played it in the mid 90s-ish.
cool, i will research about👍🏻
this is not how the accident happened...they were running the reactor at such a low level that they could not maintain the chain reaction they restarted the reactor when steam excursions caused power spikes causing them to scram the reactor using the control rods which were tipped in graphite which allowed neutrons to hit the fuel more efficiently causing a large power excursion that caused a steam explosion.
It is true that they removed to many rods is a part of the disaster
Thanks for putting it right. That's what I remembered, too.

PJ Chernobyl series brought me here
It was NOT a routine test! It was the 3rd or 4th time it had ever been scheduled and had never been successful. The control rods were manually withdrawn because the reactor nearly shut down and was producing 30MW, well under the required 700MW required for the test. Xenon poisoning was one issue that led to the very low power level and slow response to the withdrawn control rods.
Yes, Xenon gas building up inside the reactor was one of the main factors why the reactor went out of control. But the reason they could no see it on the instruments during the test was that the sensor was placed in the middle of the reactor and RMBK have different power levels in top and bottom. It was a major construction fault and USA had warned that this type of reactor could become unstable at low power levels. That is why the rest of the world abandoned it in the 50's. The safety system was also turned off to make the test if the reactor could be restarted from low power levels. The test proved it could not!
Fredrik Hansson what would have happened if the control rods weren't lowered?
Also I'm shocked to find out it was operational until 2000, why stop then? Also isn't it possible to reclaim the nuclear material from 4 using RoboCop or the T800/1000¿
Oh ok so all not for nothing, at least we know that it cannot start at such low levels. One must sometimes make mistakes to learn...

The other 3 reactors are so dangerous they had to shut it down as soon as they could, but they couldnt leave the nation without power

The disaster was also partially caused by a high ranking officer's decision to run the test at extremely low power which lead to the loss of control of the fuel rods. The test should have been run at 700-1,000 megawatts, but the vice-chief engineer of Chernobyl, Anatoly Stepanovich Dyatlov, wanted to push the limits of the reactor and insisted it be run at 200 megawatts instead. The same engineer ignored the warning signs of a possible meltdown and continued to run the test.The blame shouldn't rest only on him, but he was the one who ordered the test to be run at an unsafe energy level, which lead to the loss of control of the fuel rods, which lead to the reactor overheating and the steam explosion. A better documentary would be the 'Zero Hour: Disaster at Chernobyl' one which does a great job of explaining the science behind everything and goes really in depth about the reasons behind the accident.
There actually was no meltdown at Chernobyl. A meltdown results in fuel element destruction and damage to the reactor. At Chernobyl, the fuel melted after the reactor had been destroyed by the steam explosion and there no longer was any way to cool the hot fuel elements or cool the resulting decay heat from fission product decay.
Roger Rabbit is right
But how could Dyatlov be the one to fault if he was on the toilet????
"The disaster was also partially caused by a high ranking officer's decision to run the test at extremely low power which lead to the loss of control of the fuel rods"
There was no loss of control of the fuel rods, did you mean control rods? Control of the control rods was maintained until the structural integrity of the reactor began to break down after activation of EPS5. Deputy Chief Engineer Dyatlov was only there on an oversight role and had no control of the reactor, control was strictly within Akimov's jurisdiction. Karpan was also in the room that evening, and he was another Deputy Chief Engineer of Dyatlov's rank, who stood next to Toptunov and helped him restore power after the accidental power drop when switching between automatic regulators. Did you know there were actually MANY people in the control room that day? Shut downs and tests are very important, and there were many tests planned for that scheduled maintenance shutdown.
"The test should have been run at 700-1,000 megawatts, but the vice-chief engineer of Chernobyl, Anatoly Stepanovich Dyatlov, wanted to push the limits of the reactor and insisted it be run at 200 megawatts instead."
Incorrect. The 700 Megawatt rule was an advisory rule, not a compulsory one. Dyatlov did not insist on 200MW/t to push the reactor. The reactor sustained a near total shutdown of reactivity when Toptunov switched from local area regulators to global area regulators as the power descent was conducted towards the turbine rundown test. Unfortunately, due to poor design of the controls or operator oversight, the automatic regulators malfunctioned and decreased power level to zero MW/t. A decision was made to raise the power as soon as possible before Xenon build up, and neither Dyatlov nor any other senior NPP personnel had any objections. Again, not against regulations written at that time. Once reactor power was stable at 200MW/t and waterflow fluctuations were worked out, they decided to run with the test and disconnected turbines to observe rundown voltage while the reactor itself was shut down as per test plan. Many different factors then pushed the reactor into a critical state, primary factor was ofcourse the design of control rods (shortened graphite displacers leaving a water column in the bottom 1.5 meters of active zone) and the function of the AZ5 button (only upper rods inserted, lower rods coming into the zone from below were not triggered, this would likely have saved the reactor). Post accident RBMK revisions included both fixes, now graphite displacers are telescopic and encompass the entire length of the active zone. Also, AZ-5 triggers shortened rods which insert from the bottom of the active zone, completely eliminating power spikes in the most essential area of the active zone, the bottom, the core inlet.
"The blame shouldn't rest only on him, but he was the one who ordered the test to be run at an unsafe energy level, which lead to the loss of control of the fuel rods, which lead to the reactor overheating and the steam explosion."
Had Toptunov and Akimov survived, they'd have been held responsible too. However, I don't blame the operators at all, as they were essentially working blind. All prior NPP accidents in the USSR were classified, reactor research and specifications were also state secrets, there was no communication between different NPPs regarding faults and accidents due to KGB interference. So, the operators had no idea that their reactor could be pushed into a dangerous situation by faulty control rod design. Remember, it was the control rod design with shortened displacers which served as the detonator here.
" A better documentary would be the 'Zero Hour: Disaster at Chernobyl' one which does a great job of explaining the science behind everything and goes really in depth about the reasons behind the accident."
While this documentary has great actors and set design, it is operating on old, outdated and frankly downright incorrect information which has since been debunked by the IAEA and their INSAG-7 report. I recommend you read this. Please, do not spread misinformation online.

After reviewing the video for the third time RFE got some of the most important details and facts wrong.1) They were not testing the "Back Up Cooling System" they were testing to see if they could keep the generator excited during the coast-down after the reactor tripped so that they could keep the pumps running until the Diesel Generators came to speed and loaded.2) There was no "Routine Safety Drill". This was a brand new test to explore the lag between Reactor trip and diesels coming on line.3) There is no mention of a steam explosion. Only explosion, leading most of the non-educated people to naturally assume it was a nuclear explosion. It was not. This is fear-mongering alternative facts. Just enough whizz-bang graphics and a knowledgeable-sounding narrator to get your attention.I don't downplay the severity of the accident. But it would be nice to see more facts presented in a less dramatic method. The accident happened. The Nuclear industry learns form it. Why not the public?Read Piers Paul Read's book "Ablaze-The Heroes and Victims of Chernobyl" Very well written, chock full of facts and human stories.
This whole video is a load of crap, completely wrong information altogether. I have yet to find a documentary which is one hundred percent accurate. I would suggest to everyone to consult the INSAG-7 IAEA report and learn to read.
,
It was a graphite moderated reactor, so METALLIC Uranium was used - which is pyrophoric in atmosphere (with +- 20% Oxygen..)
When a steam explosion ripped & blew the lid off the reactor vessel,
the metallic Uranium came in contact with the oxygen in the air,
and started to burn like pyro-technics,
(& that's what whitnesses saw that night - in the very early morning),
together with the Graphite which also took fire, since it is pure Carbon..
.
In water moderated reactors, the Uranium in the ZircAlloy fuel rods consists of pellets (little cylinders) of sintered Uranium-Oxide.
.

@@rogerhelbig9458 Multiple Russian language and foreign powerplant engineering analyses of Chernobyl.
Soviet archives show that one of their lead nuclear inspectors had visited Chernobyl as one of the scheduled follow-ups after the previous disasters.
Her report revealed that the concrete works and repairs were shoddy, as was the steel construction. She also discovered a theft ring among plant workers. Her comments indicated that she perceived another disaster would happen at that plant due to the culture of recklessness, insufficient quality controls in corrective repairs, and theft of tools and other materials at the site.
I wondered if they sold off their higher metering dosimeters and Geiger counters, since there was difficulty getting reliable readings after the explosion.

The staff pressed the wrong button that's why the control rods started jumping and increased reactivity, if the staff pressed the correct button, the aftermath would have been better, look in the shutdown scene and read the button sign it says A3-5 it didn't say AZ-5, the staff pressed the wrong button due to panicking or the staff intentionally sabotaged the core or more likely the staff didn't read the button sign.
@@jmsta.romana4660 Sorry, I think you’ve got it wrong. The A3-5 is the same as AZ-5. The letter Z in the Latin alphabet is 3 in the Russian alphabet.
@@aulinjake Ok Jacob, Thanks for pointing out. I didn't have any idea that Russians use 3 as Z in their local Alphabet.
Iconic chimney is still there!
Very helpful video and one of the best comment sections I’ve ever seen.
And that's how a RBMK reactor explodes...…..
RBMK... a reactor so advanced, that it didn't even have a proper reactor building. Soviet engineering or something.
***** The personell definitely had a big responsibility but quite frankly building a nuclear reactor _without a reactor building_ and with control rods that are _tipped with reaction-increasing material_ is a pretty egregious flaw. No reactors are built like this anymore, nuclear power is no more dangerous than taking the plane or living downstream from a dam (actually, dams may be more dangerous).
M Rotgans your right and the RBMK or the crue member itself
Yeah that's why we haven't seen any big nuclear disasters in recent years (#Fukushima #worsethanchernobyl)
Fukushima worse than Chernobyl? WTF man? Fukushima was a sneeze compared to Chernobyl. Despite the absolutely shit management by the Japanese government/TEPCO company there was no uncontrolled nuclear "fizzle" and no aerial dispersion of heavy nuclear core materials. That's a pretty big difference.
Yeah thats what the media love you to believe.. Did you know they don't even know where the corium is in 2 of the reactors there? It may already be melting through all the concrete bases into the soil underneath... The robots they sent down to check all stopped working. And this is right next to the pacific ocean. Try to think about the consequences if that corium hits the ground water. The situation in Chernobyl is stable now, this is not the case in Fukushima. They have no clue how to solve that mess!
Nice vid helped A LOT thank you!
I don't know where this channel got its info, but the confinement structure is not nearly big enough to fit the titanic inside. The Titanic was 883 feet long and the Confinement is 541 feet long.
I'm fairly certain theres a lot more mistakes in this poorly made video but I don't want to do the math for all of them.
I used to think this video was accurate, it isn't. Thanks HBO.
How about reading and doing research rather than depending on others.....only way to get the full picture
#stopthewar
Spoiler: they finished in 2017, it started crumbling in 2019 due to the strength of radiation. If I'm not mistaken they are currently in the process of fixing it
Maybe a weird question, but are the reactor cores 1, 2 and 3 removed? I know that Reactor 2 suffered from a fire and that the roof Reactor 3 is damaged, where a part of the roof has collapsed.
Unbelievable what really happened over there.
3 and a half minute video for a 4 second ‘explanation’ of what happened.
REACTOR GO BOOM. BIG BAD RADS. PEOPLE SICK.
Dan Smith what’s that got to do with this video?
Oh my god that opening sent chills down my back.
Great video! Thank you :)
We will never see the poor chimney or the reactor 4 again, so sad.. At least keep the chimney in the backyard for the reactor 4!
The old chimney was replaced by a new one
I think they sold the chimney on ebay
WarthDader74 for nuclear fuels or control rods or 5000000$
R.I.P. The chimney that simbolised the danger of nuclear energy.
A huge oversimplification of what happened...procedures were not followed. No mention whatsoever of the Xenon poisoning of the control rods, which rendered the control rods temporarily ineffective, nor does it mention the hydrogen buildup which would have occurred in the reactor hall, creating a hydrogen explosion that helped the steam blow the roof off of the reactor hall. The Xenon poisoning of the control rods happened because of a failed attempt at the same test earlier in the evening. Had the control rods not been Xenon poisoned, the meltdown would not have happened. Had the operators waited for the prescribed time to allow Xenon poisoning to clear, the accident would not have happened.
And just like that everyone on here is a nuclear expert and are professionals and scientists.
Every comment:
"No, what actually happened was [things explained in the video]".
All pro nuclear esports players, somehow, just now, learning everything they know about Chernobyl in the last *(checks comments)* six days.
This is simply not what happened.
"Please, tell me how an RBMK reactor core explodes."
Well explained and quick video very nice
"50 thousand people used to live here, now it's a ghost town"
wooow man COD MW 1 - City Of Pripyat :)
True
- Capitain Mc Millan
Cod 4
I Q J .... why use other people's posts regarding what happened at Chernobyl ? Use your own imaginative brain . Instead of stating that 50-000 + lost their respective homes ! . That others have already stated ?! ... you sad individual .
Waiting for the HBO fans to turn into nuclear physicants.
Started watching the show but why were the rods removed at 1:24? Was that part of the test and why?
Thank you for this video
"THE REACTOR CORE EXPLODED"
"Thats not possible, just put some water on it" lol
1:33 Reactor No.4: "Mr. Reactor No.3 *I don't feel so good...* "
History is repeating itself
RBMK reactors cant explode, get him to the infirmary he's in shock
The Reactor! It exploded! I've seen it with my own eyes.
"Continues to vomit"
He's delusional! Take him to the Infirmary. Lmao
ACTUALLY after 48 hours of sweden finding out where the radiation leak was coming from, THEN people around chernobyl were evacuated. For days soldiers with masks tried to take care of the accident BEFORE the public was evacuated and told the nation. Thats life behind the iron curtain though...
Where can i watch full detailed documentry on it ?
What software was used for this animation? Please help
RIP Chernobyl Red and White Chimney.
You will be missed.
One like=one prayer for this glorious chimney.
How does an RBMK reactor explode? Answer: Lies....
Bhopal gas tragedy, eerily similar to Chernobyl, happened in 1987, just a yr after C disaster. Poisonous gas leaked out and caused many deaths.
You didn't even mention about the tip of the control rod having graphite.
Vaibhav Shinde because its cheaper
The documentary "uranium: twisting the dragon's tail " from pbs, explains this with more details
Dude, worst explanation about chernobyl disaster i have ever seen in my life.
radiation measuring sound is the most scariest sound i've heard in my entire life...
38 years ago today (26/4/2024) this horrible incident took place. May it never happen again.
Its just the equivalent of a chest xray
bigmaxy07 200X
Who’s here before watching Chernobyl?
Borys Shcherbyna's son is Alexander Johan Hjalmar Skarsgård
that explanation is so vague very simplified many things happened that produce the explosion
