@@quattrodrift3376 so basically because of the heat going threw the pipes near the steam separators the walls around them started to separate and because they built the reactor around the building if they hadn’t repaired that then it could have all collapsed on the building
@@quattrodrift3376 Insulation of walls was bad, reactor's water heated up the concrete walls and the concrete started to become weak, which caused floors and walls to move and shift.
And this right here is exactly why I look forward to every Saturday evening. While I had read these very few lines about this particular mishap, and knew it has something to do with the integrity of the building itself, it was never quite clear just how bad it actually is. I have that KGB Dossier book in pdf, but haven't got around to translating any of it yet. And here you are, putting out another gem of a video with exactly that info. I think we can safely say that it is a small miracle they "only" lost one reactor unit at Chernobyl NPP. With these kind of major construction flaws, it might easily have been more. It does not bear thinking about if one of those steam drum separators had come loose, and deprived Unit 3 of coolant....😱
Concrete overheating is a well understood problem for all power station designs, from coal stations to nuclear. If you overheat the concrete either when it is first poured or later in use, the crystal structure changes and it expands breaking the concrete away from the reinforcing bars and permanently weakening it. If the concrete is a beam it will get significantly longer, potentially jacking the whole building apart, perhaps resulting in upper floors no longer being supported on their associated columns etc.. Generally there is some provision for this in the design because this is a progressive problem which occurs more slowly at lower temperatures. From what I understand (I'm not concrete expert) this is quite dependant on the exact concrete mix, water content when poured, ambient temperature when poured etc. Having spoken to western professionals who visited Chernobyl before the R4 accident it was obvious that some of the concrete construction was of dubious quality, and an example of what they considered poor construction quality control.
When i see the iceberg video for the first time, I was very interested in this incident, but I couldn't find any info about it, so I'm very happy for this video, Saturday is always better when you release a video.
Another great installment! I'd like to know if the RBMK creates a rumbling vibration from the 3GW of thermal boiling. I've worked on giant magnetrons and the water boiling shakes the concrete floor enough to make other building occupants complain, and you can feel it with your feet. If so, some of the RBMK vibrational energy might have been transmitted into the concrete, disturbing the joints over time. Has anyone worked at a plant of this colossal size? Can you feel any vibration when it's operating? In the case of Chernobyl, thermal expansion and overtemperature of the concrete would have certainly been a factor, but considering the constant uptime of the RBMK, the total number of thermal cycles may have been a lot smaller that a plant that cycles once per day, such as a peaker plant. Chernobyl was a base load plant, and so it was always on, except for maintenance. Thanks for another great video!
@@SarahLowrey-- Thank you. Interestingly enough, there is a counterexample. In the dubious HBO documentary about Chernobyl, in one scene ostensibly showing the behavior of the RBMK during the extreme power surge in the core, the metal shielding covers of the cooling channel tops on the reactor floor are shown to be bouncing up and down from the extreme internal vibration. This scene could be utter nonsense, however I believe there is at least one written account mentioning the observation, and the scene may have been based on that. I highly value your direct experience, and do not doubt your word. The amount of vibration at normal power levels was certainly nothing of the sort. The tremendous physical mass of the RBMK alone, would tend to attenuate any vibration to the point where it might be unnoticeable. I believe, however, there may have been a low amplitude rumbling similar to what I've felt, from the RBMK core and possibly from the steam drums, and if so, the concrete would have been exposed to it year after year. When you see a drawing, a picture, or a video of a machine, it is just static, but when I was standing right next to a boiler and steam separator, I could feel it. Disclaimer: I've never worked at a nuclear power plant.
I have the assumption that due to everything being narrow pipes it would have been like when you are boiling water in test tubes too rapidly and he steam bubbles then propel a large slug of liquid out of the test tube. I can imagine that something similar would occur here so that instead of just steam you instead would have this type of 2 phase flow going through all of these narrow pipes right into the steam generators. This uneven mix of water and steam at high pressure would surley create lot of vibrations in the piping system almost like water hammer. I have no idea about the actual steam / water ratio going into the steam separators but I can imagine it would behave somewhat like this due to the fact that everything is made up of narrow pipes wich would cause the steam to push large slugs of water with it through the system..
Unit 3 was reportedly considered the least safe reactor in the USSR. It had a vulnerability to fire that could utterly cripple it by collapsing the steam and pumping system, and there was a massive chemical storage bunker right next to it. The realistic worst case scenario for Chernobyl was probably the fire not being put out and being allowed to damage Unit 3.
Nah, thats not it, they didn't quite let complete idiots build npps, there are quite a few vids floating around about the construction, shit got inspected, tested or whatnot. This has more to do with russian national 'Авось' - roughly translated in 'It'll be fine', sometimes it is... Tofu dreg on the other hand is completely malignant version of that.
Way back I actually looked it up on wiki, and from there I found there were issues with the others, but until now I was unaware of the extent. My guess is, as sketchy as they were, they didn't blow up, a.k.a nobody gave a crud.
@@ToreDL87 yeah and tbh the 4th reactor explosion just makes everything else about the power plant more fascinating yet scary, explosion = monkey Brain 😯
Just a little video error: The text for the Unit 2 Turbine Hall Fire at the beginning says "1982" under it, instead of "1991", even though you still mentioned the correct year. I'm just being nitpicky. Love your videos!
Thank you, the paper I found it in listed it as an RBMK steam separator, so I apologise for the confusion. It still works as a good enough diagram, I hope :)
Probably cost-cutting. Just like the turbines for unit #4 were of a different design than the others, using less rare metals, but making them more susceptible to vibration and requiring frequent maintenance.
Could you do a video about the 1982 unit 1 incident I’m writing an essay about Chernobyl and had to use Wikipedia and other sources to be honest I understand and remember better when information is spoken
Sir, how those plants are founded? How deep is bedrock from baseslab of unit three and for? I got impression, that all those things are founded to swamp with minimum replacement of soil.
It was build way to fast due to bonuses for the managers. Now i suddenly realize why the product of the soviet union was this cheap heap of crap called the RBMK failed...
The RBMK reactors at Chernobyl have been at high risk almost from the day of their completion. Their design is flawed. Others like them around Russia have been updated at enormous expense.
Chernobyl was a dual use power station, two targets: 1) make electricity 2) make plutonium for the military The refueling equipment was on top for a reason: to make the refueling easier and faster
So now I can tell RBWR trainees don’t have a rod temp imbalance or else it’ll be Chernobyl unit 1, don’t disconnect from grid and touch electricity grid or else it’s Chernobyl unit 2, and don’t overpower reactor or else it’s Chernobyl unit 4.
I would think it is good if you say the numbers in the reaktor picture. You talk about parts, but i dont know everything or where it is located. best regards :)
so ive done research on CNPP for years and just reading and watching documentaries the whole building for 3&4 were rushed because they were the newer era RBMK's. this is why that whole structure is slowly crumbling, now the question we have his. "did Novarka ever pick up on this ?"
Which classical piece is better Beethoven nine or Beethoven five? I think Beethoven five is more suitable for the Chernobyl disaster a very dark opening… Basically the opening is the opening of Beethoven’s fifth symphony with the exception of Beethoven ninth Symphony it has a much better opening, and of course, followed by the joy Joy so OK OK so to joy so it is an ode to joy by Ludwig van Beethoven between 1923 and 1924 and 1824 I believe 1823 1824 Beethoven, so who is Ludwig van Beethoven? Is the greatest composer of all time has to go to Beethoven, he’s also followed by Wolfgang Amadeus Mozart and Johann Sebastian Bach And also Georges Bizet
Just wanna say thank you most people only know about the one accident let alone all the other ones been about 24 years now researching it and there’s always something new I find it’s amazing after the accident happened in unit four it was basically a worldwide experiment One question I’ve had for a while do you really think it was an accident i’m not a nuclear engineer but I have a few weird questions
Fascinating piece containing images I have never seen, and I worked in the nuclear power plant industry rom before the 1986 accident to a year ago. I do recall we were given a report of what happened at Chernobyl several months afterwards, but I suppose it was just a translation of the Soviet ruse.
so, for the entire video you keep stating "the unit 3 accident" but in actual fact, there wasnt an accident at all. THATS why no one knows about it. so this entire video is just Russia bashing
Chernobyl being SNAFU is one of the classical soviet stories that never gets old...
The whole Chernobyl plant really was cursed. It's truly amazing that the 1986 disaster was only as bad as it got.
