  • High detail 3d animations and explanations of the inner workings of Chornobyl nuclear power station. Showing why it was so vulnerable to blowing itself up and how it was different from western reactors.
    Illustrated here are:
    The absence a reactor pressure vessel and containment structure.
    A size comparison with the Fukushima reactor and its containment layers.
    The uranium fuel assemblies and graphite bricks.
    The control room location.
    Close up views of the explosion crater with the reactor lid nicknamed "Elena" shown flying through the air.
    The temporary radiation shield "sarcophagus" and the final permanent confinement arch.
    Chernobyl was a nuclear power station in Ukraine, Soviet Union. Its reactor blew up on Saturday 26 April 1986 at 1:23 am.

    4:00 Ackchyually! Nikolai Fomin as the chief engineer was relatively inexperienced when it came to nuclear reactors, Anatoly Dyatlov on the other hand was very knowledgeable with reactors and many of his junior colleagues looked up to him, it's part of the reason why the reactor operators went along so recklessly with his instructions, "The old man knows best" was the thinking.

    • @Mike-Bell
      @Mike-Bell  Před 4 lety +18

      Dyatlov had extensive practical experience of reactors which including from the construction of the Chernobyl reactors. However his theoretical understanding of reactor physics was clearly limited especially how at low power the RBMK was extremely precarious. At full power this reactor was predictable and stable however at low power when the xenon poisoning and heat slowing effect were absent this reactor effectively had no brakes. Dyatlov didn’t understand or believe this. The Soviet Physicists knew about low power precarious nature of the RBMK and had included safety procedures to manage the risk.

There is a lot of contradictory statements out there, some who want to paint Nikolai Fomin as a complete buffoon who had no understanding of how a reactor worked, others that say Dyatlov was an irredeemable cunt, certainly how HBO's Chernobyl tried to portray him as well as general incompetence.
      Statements made by Dyatlov's colleagues seem to contradict this picture however, at least from what I've seen. I wish I had my sources at hand but at least one of them said something to the tune of; Dyatlov knew the reactors like the back of his hand and everyone relied on him.
      Another reason why I doubt the official narrative is that Akimov supposedly claimed to his death that "he did everything right" which never sounded quite right if he was a totally unwilling stooge in the drama but I've not taken the time to read the actual transcripts and to be quite honest, it was still the Soviet Union, a dead man can be sworn to have said anything.

      @@abrahamedelstein4806 Dyatlov knew about xenon poisoning. You can watch his last interview, where he said that, plus on official chernobyl NPP channel, you can find alot of intervies with his collegues, that confirms, that he had realy good knowledge about reactors, even theoretical. Atleast it's all the sources i can remember right now, problably there is more, but they are mostly on russian. If i remember correctly, he doesn't know only about tips, altho Fomin can knew about it (Leningrad npp get this effect earlyer and tryed to warn other npp with RBMK about it, atleast that stated by Valentin Kupnii, that was a director of beloyarsk npp before accedent and become director of... I dunno how to translate correctly, but basicly in charge of sarcofagus). But again, this reactors was realy hard to maintain, even at high power. So there was alot of situation, there operators, in kinda similar condition (after a long working on low energy levels) just "burn" xenon by increasing power inside. It wasn't that common, but it was. So, it's easy to think and blame Dyatlov, as almost whole ussr did, but reality is so, that he wasn't more then a cog. If he didn't be there, somebody else had all the chances of making same mistakes. And that's why "system" was involved and was responsible for all this. If you know about Bhopal, it's somewhat similar situation.

    The reactor had operated for 20 years prior. It had design flaws, but this was caused by negligence of Dyatlov and 2 of his techs.
    The reactor was undergoing a 24 hour shut down procedure, allowing for a specific test. The test involved disconnecting one of the turbines from the reactor, as it was being wound down, and using its energy to power water pumps. The test should have been a one off, lasting only 45 seconds.
    Anatoly Dyatlov (head technician on midnight shift) planned to lower output to 700 Mw, the lowest setting at which the reactor should have been operated.
    But he failed to properly set it up and the output fell below 100 Mw. Instead of allowing it to shut down, he tried to bring the reactor output back up to 700 Mw, in order to perform the test.
    To do this, he overrode safety systems and warnings, and ordered graphite control rods MANUALLY WITHDRAWN from the reactor.
    The rods are a critical safety mechanism; if the system senses a run off reaction, it will automatically lower these rods into reactor and sap off energy output.
    Sadly, he ordered the rods disconnected from the system, so that it would not interfere with his quest for more heat.
    Once the positive heat loop kicked in, it kept increasing the water temperature in the reactor, in turn causing higher fission reaction, and on and on. The heat and pressure built up, until reactor 4 housing and piping exploded, propelling a 1,000-ton concrete slab above it clean off the building.
    The reactor was now exposed; contaminated water and coolant were spraying everywhere.
    Dyatlov was sentenced to 10 years of prison, but was released in 1991 after collapse of USSR. He tried to scape goat authorities, apparently ordering him to press on with a not so important test and jeopardize billions of dollars and national catastrophe. In reality, he was public enemy #1 and public demanded his execution. He died in 1995 from heart attack. czcams.com/video/Cc-vvhWXL9Q/video.html

You know that Leningrad Power Plant's RBMK once almost exploded too? The only thing that saved them was fresh fuel, so the void coefficient was a bit different. BTW the modifications made to reactors later have still not made them safe enough in case of bad operator. So it's quite surprising they kept them working until 2000, but it was necessary because ukraine needed power. In Russia they function to this day, but russians have lower standards when it comes to human safety and they are too dependent of those reactors, because they have even more of them than Ukraine, and russia is not so wealthy today.

    CANDUs and RBMK's share some design similarities (online refuelling, pressure tubes instead of pressure vessel, physical size due to low-enriched / natural uranium) but have some significant safety-related design differences. CANDUs are moderated by liquid heavy water, not graphite, and the water-filled reactor is immersed in another large tank of light water called the shield tank. As a result, the CANDUs have a significant amount of passive cooling capacity, and water doesn't catch fire. Another critical difference is the CANDUs are fully inside a concrete containment structure, and the Ontario Hydro multi-unit stations have a massive negative pressure vacuum building to reduce pressure within the containment building if there is a large steam release in containment as a result of an accident. CANDUs do have a positive void reactivity, and for this reason they have two independent, fast-acting shutdown systems that are physically separate from each other and the control systems. Each system is designed to shut down the reactor in a matter of seconds on its own without needing the other system, however both systems are designed to initiate shutdown independently and immediately if a design-basis accident occurs. Also, following the Chernobyl event Canadian engineers travelled to the Soviet Union to learn what happened and determine if anything needed to be fixed or addressed in the CANDU design. There weren't any significant design issues identified in the CANDUs, but one operating change was to reduce the maximum flux tilt allowed within the CANDUs before reactor trip is initiated. This reduced maximum flux tilt limit is still in use today. Great video, btw. (Edit: corrected "end shield tank" to "shield tank". The end shields are distinct from the shield tank.)

      it has to be said tho, that they didn't want to stop it there, the RBMK was originally designed to work at 50% efficiency or more using supercritical steam turbines, so the RBMKP-4800 could have outputs of over 7700MWe per block, they also were thinking in using a fast neutron version of it with 15% enriched uranium that could have much higher power outputs since fast rectors have very small cores that they wanted to make very big, the 1300MWe BN-1200 fast breeder will have a core of just 85 in height and 2 meters in diameter.
      it has to be said tho that 1500MWe and thermal power are very diferent things, generally the sweetspot for reactors is around 2700-3300MWt, the EPR thermal output is 4650MWt, the Mitsubishi APWR and General electric ESBWR have 4550MWt and a power ouput of 1780MWe, altho japan planes to scall them down to 3280MWt/1300MWe very large reactors are bastards to build, the Chineses are studying to scale the Westinghouse AP-1000 to make the AP-1400 and then possibly the AP-1700 and AP-2100 with a thermal output over 6000MWt

      The sweetspot for nuclear power size is around 2700-3300MWt, where scalability and size meet, larger than that and you need a higher degree of engineering to guarantee the safety of a 4.5GWt reactor that has pretty much the same pressure vessel as a 3GWt one, as such the level of engineering of the safety systems increases more than the possible benefits of a larger thermal output
      The workhorse of france's nuclear industry has been the 900MWe class, while the reactor on which the epr is based, the N4 has been taken 15 years to construct in chooz and civaux.The EPR-2 hopefully will have around 1300MWe and 3200MWt, it simply becomes less challenging to build.
      The same issue happened to South korea, they builded the OPR-1000 for 1900U$D/KWe, and when they decided to supersize it into the APR-1400 they ended building those for 2250U$D/KWe, they are planning to replace it with the iPower with a output of 1200MWe and 3200MWt

    I enjoyed the graphics in this video, they give a good overview of the structure and the damage afterwards.
    One question I still have about the original design of the control rods: the bottom end of the rods were graphite which is a moderator meant to increase reactivity. When these are inserted, the graphite was meant to replace the water inside the control channels. Some videos mention that this water is an absorber (decreasing reactivity) while other videos mention that hydrogen (the H part of H2O or water) is a moderator. What were the graphite ends of the control rods meant to do originally? replace a moderator or replace an absorber?

    • @jordanpottruff3602
      @jordanpottruff3602 Před 8 měsíci +7

      Light water is both a neutron moderator and a neutron absorber. As in, when a neutron interacts with water it can either be absorbed or it can "bounce off" with less energy, i.e. moderate. In isolation, its net effect is predominantly as a moderator, boosting reactivity. In a typical western reactor, the water is the sole neutron moderator. As more water is added, the power increases, and if the water is lost or boils away, power decreases. This creates a negative feedback loop that can help prevent a runaway chain reaction and helps stabilize the reactor.
      An RBMK, however, is graphite moderated. The graphite moderator provides a substantial boost in reactivity that allows the reactor to run on far less enriched uranium, saving on operational costs. The impact of that, though, is that water is no longer a net moderator but instead a net absorber. This is because there are diminishing returns to moderating neutrons. The graphite is already ***heavily*** moderating the neutrons in the core, and the addition of water through the reactor has a comparatively negligible moderating effect. The water's absorbing effect is now more pronounced, making it a net absorber in an RBMK.
      Effectively the impact of water on reactivity has reversed compared to a typical water-moderated reactor. In an RBMK, as water is lost (e.g. by boiling it), the power will increase, boiling more water, increasing power more, boiling more water, etc etc etc. This is what is referred to as the positive void coefficient, it is a positive feedback look that makes the reactor unstable.
      Back to your main question--the water is an absorber in an RBMK, and the graphite extensions are therefore meant to replace an absorber. The reason for this is that it creates a greater differential in reactivity between the rods being inserted and withdrawn. When withdrawn, the graphite is within the reactor and boosts power. When inserted, the graphite moderator exits the bottom of the reactor and power decreases even more.
      Without it, the control rod (an absorber), when inserted, is simply pushing away the water in the channel, which is another absorber. The water is admittedly a worse absorber than the control rod, but the result is that the impact of the control rod is less significant nonetheless. So the graphite extension helps compensate for this effect.

    @markusklyver6277 Před rokem +13

    I believe the video is wrong. Temperature does decrease the radioactivity. The positive void coefficient has to do with steam: if the coolant is a liquid, it may boil if the temperature inside the reactor rises. These steam bubbles are called voids. The amount of void inside the reactor can affect the reactivity of the reactor. The change in reactivity caused by a change of voids inside the reactor is directly proportional to the void coefficient, so it is a scalar. This has to do with steam, not temperature.
    The Chernobyl reactor did have a negative temperature coefficient, meaning that higher temperatures slowed the reaction down. However in the lack of control rods and fresh coolant, this wasn't enough to stop the reaction from becoming an explosion.

    • @thompsonmatthew
      @thompsonmatthew Před rokem +2

      Don't overlook that the steam voids are ultimately the result of an increase in temperature. The void coefficient was so significant in this type of reactor that it dominated other coefficients including the fuel temperature coefficient.
      An increase in temperature creates steam voids, and because the reactor is graphite moderated, it leads to an increase in reactivity, which further raises the temperature and reduces cooling capability - then this repeats - a disasterous positive feedback loop.

    The somber tone and narrative fit with the terrible event. I particularly liked the clarity in description of the chain of events.
    Especially the comparison with Fukushima with its stable design and triple security (and even THAT went wrong) was very instructive. This is among the best nucler sisater analyses I've seen, and I've seen quite a few.
    A cynical, society, af lawed design, unqualified management. Lives destroyed in the tens of thousands in Pripyat, and in the families of the cleaners. Still gives me the shivers.

    Great video. There is a slight correction to be made. The reactor did actually slow down with increase in temperature (negative temperature coefficient). However, it did have a positive void coefficient which has nothing to do with temperature but it means the reactivity will increase if the water converts into steam. This usually isn’t an issue cause the water is circulated but on this day they were running a test which required the pumps circulating water to be switched off which allowed the water enough time to boil and convert into steam.

      HBO isn't best source of history material for chernobyl. It's isn't documental. There are alot of... misrepresentation and somewhat errors for better emotional stuff(altho charecters are miss represented too). There is more or less better documentary from BBC - surviving disaster. It's still share some drama acting and so on, but more close to better charecter representation.

    • @andrewrominger2537

      @@060POTEHb sorry I didn't mean to imply the HBO series is documentary level accurate. It's definitely more of a docu-drama but it is much, much easier for the average person to watch, and is accurate enough that it could get some people interested. I feel like the HBO series was respectful of the source material and stayed true to the major events while also displaying the political side of things which many documentaries seem to gloss over. But you are totally correct that creative liberties were taken.

      @@andrewrominger2537 Nah, it's no problem. Don't be sorry. My point, mainly was - if you don't watch BBC surviving disaster, i'm advising you to watch it (it's availiable here, in youtube, but quality of recording is so so). If you like HBO's chernobyl, you'll, probably, realy enjoy bbc's one. It's much older film, have it's downfalls (no that good on case of production and other movie stuff), but it's more closely get to Legasovs motivations and etc. Show his struggle before first INSAG and etc. Plus great actors performance and more close to documental film. Altho it's still docu-drama too. Or if you'd like to watch more intervies with actual people that was involved, find Chernobly npp channel on youtube, there is a series of intevievs and as far as i know, it have english subs. I can recomend much more documental content, but it's mostly on russian and subs are autogenerated...

    Three mile Island was audited and determined to be insufficient in terms of safety standards and basic engineering practices. but the worst part is NRC had a hand in not remediating said issues and the utility company refused to place the plant out of commission because they would have lost money. A bunch of documents were destroyed too.

    You skirted over one of the most important parts , the poisoning of the reactor . A major contribution to the sequence of events leading to the Chernobyl nuclear disaster was the failure to anticipate the effect of "xenon poisoning" on the rate of the nuclear fission reaction in the Chernobyl nuclear reactor. Which was as a result of the space between the lowest point of the rods and the bottom of the reactor and being run partially shut down for so long before the test was done . Which basically means the reactor was already unstable before the test was done . So many videos about Chernobyl fail to explain this .
