Every reactor at Chernobyl suffered some sort of unique accident. Unit One had its partial meltdown in 1982. Unit Two had the turbine fire and subsequent explosion in 1991, and the crown jewel of them all, the reactor explosion inside Unit Four in 1986. You may have notice I’ve neglected Unit Three here, and that’s because it’s the subject of today’s video.
This accident is so misunderstood, that the Wikipedia page only refers to it as the 1984 Reactor Three and Four accident, and while it is true it impacted Reactor Four, the effects there were minor and caught in time. For Unit Three, the consequences were almost catastrophic, and had lasting impacts on the building to this day. This is the story of that accident.

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.

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..
