Thank you. Your commentary was very interesting. When I watched it the first time I was very curious about how accurate the description of what really happened was. I am glad to hear that the scientific/technical reality is not far off (the detail about the graphite rod tips is... well, simplified but it does not kill the "what happened" explanation.) I found the first and last episodes the most terrifying. The first one with the gaping inferno well, the last- the court explanations. One faulty decision after another, piling up to the point where tragedy is inevitable. I am an Eastern Bloc child. I still remember that one of my favourite children´s books was a book that was explaining how a nuclear power plant works. :))). Russians were so proud of their science and achievements...

I realize that this video is older but I just discovered your channel because I wanted an expert's opinion on this masterful show and the Chernobyl incident itself and I found it to be very informative and fascinating. Disasters, such as the Titanic, 9/11, and Chernobyl have always piqued a morbid curiosity in me and I watched your entire analysis on the show and your reaction to the scene in the first episode where the two workers stare into basically the hellish gaping maw of the core pretty much sums up how truly horrifying and dire the situation really was and the music that accompanies that sequence really adds to it as well. It kind of reminded me of a portal to the upsidown in Stranger Things and I was half expecting the mindflayer's tendrils to come out of it. Imo, it's easily the most horrifying, ominous, yet mesmerizing couple of seconds in the entire 5 part series. In all seriousness though, It just baffles me that the higher ups could not take responsibility, acknowledge how serious the situation really was, and admit that they fucked up. Too much concern with self image and not the people smh. Also loved the background music that you inserted in while explaining things in this vid and in fact I'm listening to it right now as I am typing this comment lol. Anyways, thank you for your interesting analysis. Subscribed.

Regardless, that's how it would have come across to most viewers. People educated in nuclear power are already relatively okay with nuclear power and don't need convincing. But this specifically misleads the people who are already on edge or simply not educated on the matter, and that's where public perception matters. And from THAT perspective, the show is very decidedly a cosmic horror about the dangers of nuclear power.

Not a nuclear bomb as we call it, but effectively a 0.2 kiloton bomb powered by a nuclear reaction. I think the only reason we can't call it a nuclear bomb is because we only otherwise use that term to refer to the very special highly enriched much more powerful weapons we call nuclear bombs - which we don't really have a good alternative word.

Chernobyl Reactor #4 became more of a "dirty bomb," a bomb whose objective is to spread nuclear radiation, whereas a nuclear weapon is designed for a high yield explosion, where the radiation is a byproduct of the nuclear reaction that causes the nuclear explosion.

Yeah, in this case (and most media cases) I assume "nuclear bomb" to mean "an explosion involving spread of radiation" and not a description of exactly how an atom bomb works. I don't think the general public makes that distinction either. Radiation exposed+boom = nuclear bomb to the layperson.

The xenon pit was discovered within a few hours after the first Hanford reactor went critical. Fortunately for the program, the engineers had insisted in installing in the reactor about 50% more channels for fuel rods than the nuclear physicists said was necessary, so they were able to add additional fuel rods and overcome the xenon poisoning.

Unfortunately there is a lot of fear mongering around Nuclear power. Even these days.. people reportedly were checking in after this to see where the nearest power station was. Because this scared them.. which, in a way is understandable.. but it gives the wrong kind of message about nuclear power as a whole. Just like that ridiculous 3 mile island "documentary" that came out on Netflix. Where it was basically just interviews of scared people.. rather than what actually happened. There's a KZfaq channel who did a really good report on what actually happened at 3 mile island. The name is.. Kyle Hill He also went to Chernobyl, before the most recent war started..

I think your conclusion summerises the show perfectly. The show isn't meant to be a documentary, it's ok to have some flaws in it for dramatic effect. It's supposed to shed light on the disaster and show the impact it had to the people there. With how many things the writer's got right, I think it's ok for some things to be dramatized for effect.
@AlanCanon2222 2 жыл бұрын
Some of the wrong things in the show were believed by those involved at the time. So when they say they're worried about a patient contaminating another person, that's something that was actually said in the book of interviews by Svetlana Alexeivitch. The series doesn't point out the difference in the moment, but it can be seen as added detail, documenting commonly held misconceptions of the day.

@ScottMStolz Жыл бұрын
My impression is that the show was meant to display what people knew and thought at the time, and not necessarily what we learned later. To basically give us the experience that the people involved had. In that sense, it does an excellent job. It was not meant to be an after-the-fact technical analysis. If you want a technical analysis, other documentaries are more appropriate.

When they hit SCRAM, the graphite 'tips' displaced the water that kept the neutron flux low at the bottom of the reactor. Normal design operation kept the flux high in the centre and low at the edges (top and bottom edges) You want this because it's where the reactor core is weakest, where you've punched holes in the reactor walls to feed through control rods and company tubes and fuel and graphite stuff and so on. It's a compromise, you need holes in the reactor core floor, but it weakens the core, remember this design is something that can be built and welded by farmers and plumbers and such. So, to prevent this becoming a serious problem you have water instead of graphite at the edges, keep the heat and pressure lower there by reducing the neutron flux Problem is, when they insert the control rods you first have to push the graphite through to where the water was before the boron arrives. Which is fine. Except if you've run your core up to prompt criticality, now you've got the weakest part of the core and you displaced the water with graphite. Now you have _maximum_ flux at the _weakest_ point which cracks the fuel and those plumber's welds, _jamming_ the graphite where it does the most damage. At this point all that's left is the water acting as an absorber and all that was instantly lost in the first bang. Then it was just fuel and graphite and an even bigger bang. The reaction stopped when all the fuel and graphite was expelled by the 2nd explosion.

I think when they made the show they should have said "dirty bomb" instead of nuclear bomb. It was effectively a dirty bomb. For those who don't know, a dirty bomb is an explosive that spreads nuclear waste and radiation, and results in what happened at chernobyls exclusion zone. There was an explosion, even if only a "tame" one or multiple explosions. This explosion spread radioactive material or "dirty" material, and caused the effects that a successful dirty bomb would cause.

The only downside is that the term "dirty bomb" seems to be a relatively new term, and may not be consistent with the terminology they used at the time. I wonder what terminology they actually used in the reports.

It really intensified the series especially this track (kzfaq.info/get/bejne/l7OPe8uGxKm6ZGg.html) where the composer actually went out and sampled the sounds of an actual RBMK. It is truly haunting.

A series on the full nuclear supply chain of accidents would be better. Many of the worst nuclear accidents are largely unknown because they're forgotten or covered up. Church Rock, NM being one of the worst that released over 93 million gallons of acidic radioactive tailings and 1000 tons of solid uranium waste into the Puerco river back in 1979. United Nuclear barely even attempted to clean the mess up before resuming operations for several more years and ultimately abandoning the hot mess in 1988 and leaving it to the US taxpayers to clean it up, which to this date still hasn't been dealt with. But that wasn't the only disaster they caused, and wasn't the only company to cause a disaster. The whole industry is mired in gross negligence, incompetence and takes zero accountability for their actions. If something bad happens, they just go crying to the NRC for help and force taxpayers to hold the bag, while they declare bankruptcy, change their name or sell out and wash their hands of the matter. There are spicy nuclear hot spots all over the midwest and western US from nuclear testing, accidents and mining.

Awesome series of videos. A perfect companion guide to the dramatisation. I think some people in the comments forget that the purpose of drama is to hone in on the emotionally resonant aspects. Chernobyl is very much a story about people. The details have a lot of technical aspects but the story of is one of subterfuge, arrogance, personal loss, horror, heroism and sacrifice. Thanks again for the this fantastic series of videos.

Fascinating commentary - Thank you. Yes to both video ideas. I had family with nuclear industry background, but not myself. Still, learning more and more about this reactor design, the concerns and complexities has been riveting. Thanks for clarifying important points like how this isn't technically like nuclear bomb design, but at the same time recognizing environment impact. I'm involved with local EMA groups in a region where we have several nuclear power plants. They've operated for decades with overall few incidents, so safety culture is a key point I'm glad you mentioned.

@The Atomic Age, Hi Charlie! I really appreciate your videos, thank you. It's a real privilege to get the take from an actual nuclear engineer/physicist. This series really gripped me, I was 7 years old at the time it happened and I remember vividly the news reports from the time, and my father trying to explain to me about a sort of fire that was for some reason nearly impossible to put out. We measured the fallout in the hills in Wales where I grew up. I gotta tell you, the news was crazy back then. I remember seeing videos of the helos dropping sand, doors sliding open on the Mi-8 and bare hands shoving sandbags out before slamming the doors shut again. The next year Challenger blew up, that I was watching live. I remember seeing people somewhere in the middle east being decked by rubber bullets earlier that decade, all on BBC. Crazy times. Now that you've done Chernobyl by HBO I wondered if you ever saw the BBC production docudrama Surviving Disaster: Chernobyl ? kzfaq.info/get/bejne/jNyTatZqna3IqKs.html It's a lot shorter and less detailed, and a lot older - but it captures the horror really well. Takes a few artistic liberties here and there, is a bit more sympathetic to Dyatlov and so on. Would be interested to hear your take on it. Was supposedly based on Legasovs tapes at least in part. Before HBOs excellent series this was pretty much the only good dramatisation of the events. And I'd love to hear your intuition on the exact events and processes of the Chernobyl explosion. Thanks again, looking forward to any videos you put out :) Sam.

A better way to think of the graphite "tipped" control rods is this. RBMK is a huge reactor so it will have hot and cold pockets in terms of reactivity, if we add to that that it has a positive void coefficient the reactor has a tendency to run hotter at the top and being cold at the bottom, so by having those graphite tips they can increase reactivity at the bottom and decrease it at the top. For the control of the reactor it solves a lot of problems, but in hindsight it was a bad decision with no easy work around.

Would definitely like to see a full series on the Chernobyl disaster (and other nuclear accidents for that matter). There are some good videos out there explaining the physics and engineering behind it, but they tend to condense it all into a single 15 minute video, whereas a series on the matter could really take a deep dive.

I really enjoyed this series, especially this episode as I thought the way Legasov explained the concept of reactivity was pretty good. I haven't had anything to do with the nuclear community since 2005 and it's amazing just how much you forget so I really enjoyed your take on this series. I remember near the end of Power School we got a brief presentation of the Chernobyl disaster. That was back in 1999 so my memory of it is pretty fuzzy but I do remember they taught us the plant didn't just go supercritical but prompt critical and that it was engineered with a positive temperature coefficient of reactivity which, knowing how heat works, never really made any sense to me. How would somebody engineer something like that? Looking up the incident now as a civilian, I realize they must have mistaken positive _temperature_ coefficient of reactivity with positive _void_ coefficient of reactivity. They sound kind of similar so I guess it's understandable? I don't know. I know how S8G reactors work but I'm still trying to wrap my head around the physics of a positive void coefficient so I would definitely be interested in a video or a series explaining in depth what happened at Chernobyl.
@TheAtomicAgeCM 2 жыл бұрын
Thank you! I can't imagine how much I would forget leaving my job for a few years haha. Yes, Legasov's presentation is quite good. The red and blue cards are simple but effective. A positive temperature coefficient sounds weird, indeed. I'd be curious to see an example of that. For the positive void coefficient, I kind of gloss over it in the video, but the RBMK was designed to be very close to optimally moderated purely from a fuel/graphite standpoint. So, the water in the fuel channels had enough neutron capture to make it act like over moderated and gave way to the positive void coefficient.

5:18 nuclear fuel becomes less reactive when it becomes hotter! Can someone tell why?
@elbryan9 Жыл бұрын
@@saksham1252Reactor power is dependant on how many neutrons there are that are available to cause additional fission reactions. Anything that changes the population of neutrons in the core effects what is called reactivity. Too many neutrons (positive reactivity), reactor power goes up. Too few neutrons (negative reactivity), reactor power goes down. And of course, there can be just enough neutrons in the core to sustain criticality. When uranium-238 gets hotter, it absorbes more neutrons making it behave like a poison (nuclear poison are materials that absorb neutrons such as the control rods). Fewer neutrons means negative reactivity or, put another way, less reactive fuel.
@saksham1252 Жыл бұрын
@@elbryan9 first of all thank you for replying! So by my understanding as heat raises and reactivity increasing causing number of neutrons in fuel or core to decrease and thus eventually slowing the reactivity. And what does it mean by u238 absorbing more neutron. doesnt absorbing more neutron cause more atom to split
@elbryan9 Жыл бұрын
@@saksham1252 Yeah no worries. This stuff is interesting. That really depends on if the material is fissile or not. Fissile just means it'll fission (or split), if it absorbs a neutron. Uranium-238 isn't a fissile material. If it absorbs a neutron it'll become the isotope uranium-239 (another non-fissile material) and that'll be that. Uranium-235, on the other hand, is fissile so when it absorbs a neutron, it'll fission into two different elements which releases additional neutrons in the process. This is why enriched uranium is so important because uranium ore is almost entirely comprised of the isotope uranium-238 (more than 99% in fact), whereas uranium-235 is a little under 1%.

As an aviation professional, I can empathize with your thoughts on "dramatic pieces" as there are countless aviation features that are thoroughly entertaining but contain many inaccuracies. They are nonetheless entertaining and in many cases, reasonably representative of the events they are intended to depict.
