Also holy poo poo this show is incredible and I will be sad when it’s finished.

Edit: The lady scientist that predicted a water-explosion in the 2-4 megaton range had to have known she was wrong. Did she lie and up the stakes so that the party members would take her more seriously?

Fine, but you don’t get supercritical reactions from a fission reactor despite the failure mode. Also, a megaton is an absurd amount of explosive power. All explosions in WWII including the two atom bombs we used were like 3 megatons.

So basically the graphite absorbed an absurd amount of radiation and basically became literal death rocks

Yep, the graphite chunks that got thrown out of the building were basically doom rocks while the graphite that remained in the core caught on fire after the second explosion pumping even more radiation into the atmosphere.

The story of how the West found out about the accident is really fascinating by itself. Chernobyl radiation was first detected at a nuclear plant in Sweden which promptly SCRAMed because they thought the radiation was from their own reactor. On closer inspection the radiation they were detecting contained elements that would not be expected from their own reactor which even led to some thought a nuclear weapon had gone off somewhere and they were catching the fallout. Other plants started detecting the radiation so the Swedes got together and busted out some wind maps and ultimately traced things back to the Ukraine. When Swedish diplomats confronted the USSR the response was, "lol wut?". It wasn't until Sweden threatened to go to the IAEA that the Soviets admitted there had been an "incident" at Chernobyl.

Imagine a big cube (of graphite) with a bunch of tubes running through it like a block of swiss cheese. Some of these tubes have radioactive material, which give off heat as they radiate, and when their radiation hits the other radioactive rods those rods give off even more radiation. This is the "chain reaction" of a nuclear reactor. When it happens very fast, you have a bomb. When it happens very slowly and in a controlled fashion, it just gives off a lot of heat, which is good for boiling water to run a turbine generator like any other power plant.

This nuclear chain reaction is controlled by having a bunch of control rods that absorb radiation in the graphite block, and usually they are on a lift that pulls them into or out of the cube to speed up or slow down the nuclear reactor. There's usually a lot more control rods in the cube than there are rods of radioactive material. There's also a bunch of water flowing through the cube that picks up excess heat and carries it away. The flaw with Chernobyl's reactor was that if that water got too hot, the void of space from the steam caused the reactor to radiate more and get even hotter, which caused more steam, which caused a run away reaction. This combined with the test and ignoring other safety features is what caused the accident, when everything got too hot and caused (either a steam explosion or a small fission explosion, like a faulty atomic bomb; we aren't sure which)

Modifications where made to other RBMK reactors throughout the USSR to fix this after Chernobyl's disaster.

If you want a slightly more visual idea of what went wrong, I found a cool simulation: http://www.articlesbyaphysicist.com/ch2.html

Scroll down to the image and type in and enter "rod 0", "target 700", "cool off", then wait a minute and type "eccs off". Then just type "rod 1" to reinsert the control rods if you see the power spike too much. :)

(You can actually "beat" that simulator, by the way, by very slowly upping the reactor and cooling systems at a certain rate to burn off the excess xenon so the reactor can run clean again. It's loving hard, though, and not what they were trying to do that night regardless.)

I know, and I loving love it. So many incredible moments:

Like the explosion in episode 1, the helicopter unceremoniously falling out of the sky on the first goddamn drop was extremely effective. Mazin does an amazing job of dramatizing little things while also understating big things, which makes both really get under your skin.

The increasing horrified realization of the central committee when they're explaining how Ukraine and Belorussia will be permanently uninhabitable and the food supply of Eastern Europe poisoned forever if there's a full meltdown.

The colonel/captain volunteering to go take the measurement himself...balls of steel.

The doctor getting radiation burns on her hands from disrobing the firefighters.

If anyone wants an :unsmith: story about the three divers, I've spoiled the correction section from an online article.


CORRECTION: This Trumpet article below was based on a 2011 report from The Scotsman, which says the three men died shortly after their foray into the radioactive waters at Chernobyl. However, since this Trumpet article was written, it has come to our attention that the three men did not die as a result of entering the waters, but survived the ordeal. In April of 2018, Ukrainian President Petro Poroshenko presented state awards to Alexey Ananenko and Valery Bespalov for their bravery, and posthumously to Boris Baranov (who had died in 2005). The fact that the three survived does not detract from the heroism they displayed back in 1986. The Trumpet regrets the error.

Not trying to be a downer again, but we literally just watched 2 hours about how the state will totally lie like a rug to its citizens to minimize how huge a problem it is.

It's nice they gave a medal to 3 guys, but are they the same 3 guys who did that? :iiam: and it's not like there are a lot of their coworkers around!

It’s crazy how so much about Chernobyl is still a mystery because of Soviet attempts to bury as much as possible. Like how well never accurately know how many people really died.

we know how many people died acutely, but when it comes to radiological or other toxic accidents you can only measure mortality on an epidemiological scale. like "statistically we can assume that 5-8% of this type of cancer seen in this group of people in this area are likely attributable to the incident". like, if we have a 70 year old man who smoked heavily to deal with the stress of being a chernobyl evacuee and survivor, and he gets lung cancer, is he a victim of the accident or not? it's not really a knowable number even with perfect information

clown shoes posted:

yeah, it's a mineral called corium and it is made of the various substances in a reactor all melted together in a meltdown. the specific composition varies based on what was in the reactor and how it melted down, the chernobyl corium has a lot of silica in it because since the chernobyl reactor did not have a containment vessel it was more easily exposed, and thus the soviets had to try to dump poo poo on the core to prevent a release which would have otherwise been prevented by keeping the reactor contained. so the chernobyl corium was able to pick up material from the surrounding reactor/building plus all the stuff being thrown into it like a glowing volcano

The actual quote states 3-5 megatons. They toned it down for the show. Anyone here know if corium hitting water could really create a steam explosion rated in the megatons? All the quotes from the actual people are all very loose with exactly how it would happen.

There’s something not right about this. For years everyone reported these guys as dead. Then a book comes out and says the story was overblown and they were fine and one still works in the nuclear industry. And none of them want to talk about it. Oh and they’re healthy apart from the guy that died of a heart attack. That water would have water from the feed pipes in it. The feed water giving off 5000 roentgens. I’d love for them to have survived but... how? Unless that water was like 90% from the fire hoses or something.

I dont think its so much the "explosion" as it is the amount of radiotactive material being thrown into the atmosphere. Its three whole, and a half, of reactor cores being scattered around the greater part of the continent.

The word Holodomor literally translated from Ukrainian means "death by hunger", or "killing by hunger, killing by starvation".[28] Sometimes the expression is translated into English as "murder by hunger or starvation".[29] Holodomor is a compound of the Ukrainian words holod meaning "hunger" and mor meaning "plague". The expression moryty holodom means "to inflict death by hunger". The Ukrainian verb moryty (морити) means "to poison somebody, drive to exhaustion or to torment somebody". The perfective form of the verb moryty is zamoryty – "kill or drive to death by hunger, exhausting work".

quote:

A U.N. joint statement signed by 25 countries in 2003 declared that 7–10 million perished.[16] Research has since narrowed the estimates to between 3.3[17] and 7.5[18] million.

It's always a fun day when you have to amend your list of greatest fears because you discovered a new one, but "be trapped in a dark basement with rising water and radiation so bad that it fried your flashlight and all you can hear is the sound of water splashing and the geiger counter screaming in the dark" is definitely going on that list.

The helicopter crash happened like 5 months after the explosion, in October. Not sure why they chose to move it up to where they did, considering there's plenty of drama going on already. Unless I'm misremembering my Chernobyl facts and there was a second crash. Which I could be.

Those three dudes who went in there to open that sluice gate and drain the tanks are probably up there with Norman Borlaug as far as true heroes go.
