10:11 I will report this insane error right here for you; Show me a pump that takes 40 MW to run.. It will pump your world around. A TsVN-8 (ЦВН-8) Main Circulation Pump takes 5600 kW or 5.6 MW. The fact that none of the students are asking the instructor about this is ... scary I think is the right word.

[@JP-fn5xt]

The light water system failed obviously. Sufficient backup was not designed. All could be corrected but newer systems are better anyway. The problem being no clean up.

[@JP-fn5xt]

Correction.... Not no clean up, a very long process. Trying to come up with a better plan but it all includes robotic work.

Hi All- Thanks for watching. As it turns out, I was quite ill when I gave this presentation, and I would appreciate people's understanding in any errors I may have made. I've learned a lot since I gave this lecture, though I feel it generally presents the topic accurately. Please feel free to post any corrections you may see in the comments or on the form, and I will seek to remedy them.

[@groussac]

Thanks Jake. Not to pump up your ego, but you've got the heart of a teacher. Natural born. It is what it is. Your ideas are clearly organized and supported by detail--but not overwhelmed by detail. Best wishes for your future. BTW, if you reach a point in your life where you feel you need to reboot yourself, recommend working with horses for a while. They have a way of teaching you what is and what isn't. Horse sense. Harness horses. Unlike thoroughbreds, you can take them out on the track yourself.

[@jakehecla8904]

I'd like to add that I strongly recommend Adam Higginbotham's book Midnight in Chernobyl, which I found well-written, detailed and generally accurate from a technical standpoint. Additionally, Svetlana Alexeevich's Voices from Chernobyl is absolutely required reading for the topic.

[@dale116dot7]

To me the RBMK reactor looks to be more related to Hanford B (a plutonium production reactor for weapons) than a normal power reactor. It almost looks like the process tube/graphite arrangements the B reactor but just flipped on its side. From what I recall, coolant flow through the Hanford reactor was really high, meant to keep it cool, not meant to make steam.

[@eckligt]

They're also quite similar to the CANDU design, which has horizontal channels for the fuel, and these channels are individually pressurized, and the coolant and moderator are separate. The difference, though, is that while the moderator of the RBMK is solid graphite, the moderator of CANDU is heavy water, which is a good backup heatsink should the coolant (normal water in both designs) fail, and it doesn't tend to sustain damage or burn.

excellent explanation

[@sijonda]

I wonder how things are going since the arch was put in place. I heard since the water leaking into the facility from rain is now blocked, radiation has started to rise on it's own.

[@Swedediesel]

The reason there´s instruments missing in the control room is from what i´ve read or maby heard in a documentary is that they were re-used for the operation of the remaining reactors when their equipment broke down.

[@itsianwood]

I like this guy! Good speaker, despite the cold. The way he dealt with the idiotic 'Do you think it's haunted?' question was admirable.

[@anthonyferrari711]

Why is that idiotic? That girl clearly had a tone of joking inquiry when she said that. She may have been trying to be cute or funny. Also, this lecture took place in mid November, not long after Halloween - haunted content was probably on everyone’s minds. That said, “haunted” could mean many types of things. It doesn’t necessarily mean “oh there’s ghosts flying around!” There are absolutely haunted places in the world where you would be scared shitless to spend a night alone. And places can carry a somber feel to them, if they are the locations of tragic events. As Jake did delve further into. A general mood of a place can very much count as a location being “haunted.” Again, I’m not making any claims about what is ontologically real or not. But regardless of that, being a brilliant nuclear physicist does not mean you definitively know every single thing about all types of phenomena that exist or are experienced in the world. And such experiences can be “haunting” psychological experiences without requiring actual ghosts to be involved. Furthermore, people believing in ghosts is not that absurd of an idea. I myself don’t have much of an opinion, but certainly wouldn’t pretend as if the idea or questioning of it is “idiotic.” Yet billions of people believe in gods they’ve never seen? GTFO.

48:55 600uSv. That's about a third of the average dosage of a flight attendant (p.a.) from cosmic radiation during flight.

[@colinpitrat8639]

You mean on a single flight (if so how long)? Over a year? Over their life? Without duration this doesn't mean much. But yeah, that's relatively low. In France, maximal yearly dose is set at 1mS and is considered a very safe limit. So he did get more than half a French maximum yearly dose.

[@JaredKlatt]

I believe the average dose from NY to LA is only 30-50uSv.

[@Pismensky]

A good moment/reason to ask ourselves a question like "If there was no cold war would the USA and USSR have to develop nuclear weapons and, as a side effect, build nuclear power stations?". Please remember, we use the electricity today and have to leave highly radioactive waste materials buried in the ground for hundreds of thousand years even without any disasters, it's a "normal" nuclear fuel cycle. Would it have made any sense if there was no cold war? Is there any guarantee some guy won't reach to those sites in 200 or 300 years to spay the stuff over some city trying to get more subscribers/likes/justbecause? I'm not really a green-minded guy, just an engineer with some common sense. MIT, many thanks for the video.

[@henrimessinghausen5185]

The reason for this test was a NATO-excersize called Able Archer in 1983: Sovjet thought of the risk of a conventional attack by NATO-forces with the risk of power being cut to nuclear sites in the turmoil of war. Newly build reactors had to prove that they could withstand a powerautage. Still is unclear to me why this was ot nessecary for the older RBMK's and just for newly build ones...or that they just started with the newly build ones and the rest should follow later.

[@boese-i5g]

Don't try to think of the Soviet Union as a reasonable or cautious state. It wasnt. They were more concerned about their reputation, than safety.

@@boese-i5g You do not need to tell me of the bad sides of the so-called communist countries of the former East-block countries just because I pointed out a little, often overlooked, aspect of the Chernobyl disaster. The Sovjet Union was a bad thing for the common people... It was a abuse of powergrabbing small elite for which the commen people paid. For which the truth paid. For which the environment and nature paid. The capitalist West is bad for common people too. where the Sovjets had the need to be perceived as strong the West had the need to be perceived as free. And the common people again pay for it. Nature pays for it. In both systems only the power- and moneyhungry elite profit from a sick and corrupt system.

On the looting and break-ins happening in the Zone yes it absolutely happenes ffs you can watch videos of people doing it. These people are usually referred to as STALKERS probably in reference to the game series. Some are malicious and loot and vandalize others steal wood from the forests and some just go there to explore the area with absolute freedom. Either way it's hard to enforce due mostly to the zones size and the large amount of forest area to take cover in. But in my opinion it seems more of a race to see who gets the Darwin award first lol sine some of these people CAMP in houses and apartments in the zone

[@antimaxik]

Term "Stalker" was way before the games and Chernobyl. You can look and see there are atleast 2 movies made on this matter. Basicaly it was inspired by the books of Strugatsky brothers. The Stalker games though also was some kind of mix of Chernobyl events and the fantasy from the books

[@anthonyferrari711]

More so in reference to the Tarkovsky film Stalker from 1979. Tarkovsky is arguably the most famous and impactful Russian director of all time. Wouldn’t be that shocking for people in Ukraine to know the film. But sure, the game series plays off of all of that and certainly has some role in how the term is used today.
