Sure: soviet engineering
>Positive void coefficient
WHAT were they thinking?
How could they be so bad at engineering while being next to Germany?
>why is mexico so poor when they are next to the USA?
They did send a dog to space
But didn’ t have the skill to bring it back down. Russians just left the doggo up there to die. Life is always completely expendable to Russians.
Cheaping out on material
Russians don't have German autism.
Sometimes they just do that
they don't.
now frick off to medical you hysterical capitalist sympathizer
Off brand rod caps
hmm no i cant, nor can I explain these trips
whoa
Now that’s pretty neat right there
>using addons
>neat
don’t ya know bobby that’s just some folks vernacular
if that shit worked you'd see it way more than you do
impressive
>333.6 roentgens
not great, not terrible
supposedly its a control rod issue i belive it was considered impossible because of some kind of drainage system and rod redundancy
for example if rods fail it is flooded to dilute the reaction beyond criticality
but as always its all papper based perfection
there is no end of nuclear safe simps but all of reality conspires against them
the rods failed and the water boiled off so fast that flooding it just created more reactable medium until boom
the safety protocol just created a litteral explosion and it was already in freefall meltdown
newer desinges as im told actually keep a fuking small lakes worth of water under the reactor and drop it into the lake to try and counter this
The test they were doing shouldn't have been done, that was the first mistake
Chernobyl exploded because they designed the reactor while drunk
>Positive void coefficient: if you lose your coolant, the reaction accelerates instead of killing itself, precisely when you NEED it to stop
>Solid moderator, liquid absorber: if the absorber boils off because the reactor is going out of control, it can keep going instead of halting itself
>Moderator-tipped control rods: when you first insert the rods, the reaction spikes instead of attenuates as intended. If you take more than a certain number out, there's literally no way to put them in safely without risking a surge. See points 1 and 2: a surge guarantees an explosion.
None of these things are issues in the reactors that the entire rest of the world uses. The Soviets only insisted on sticking with RBMKs because of nationalistic sunk cost fallacy
its inefficient to do what you are saying making it even more cost prohibitive
i fully agree with the sentiment however
The problem is they were operating the reactor outside of conditions that is was designed to operate in
Those points sound scary and obviously when unexpected problems occur it will cause bigger problems potentially, but none of those things are necessarily bad if the plant was operating how it was designed
Obviously but it's still an inexcusable design flaw. It's like designing a car with the e-brake hotwired to the regular break pedal, so if the break pedal fails for any reason the e-brake goes with it. Even worse, it's glitched such that in this circumstance, pulling the e-brake incorrectly floors the accelerator. That defeats the purpose of having an e-brake. It would be considered a criminally negligent design flaw, which is the same conclusion the IAEA reached when they investigated Chernobyl.
Its not criminally negligent for what it was designed to do, those reactors were also producing weapons grade plutonium
The operators were literally doing something they shouldn't have been doing, thats the sole reason why it happened, all the other spooky shit the other anon is saying are irrelevant to the fact they were performing a test that they shouldn't have
the fact that designs don't recognise the human condition is a flaw in the design itself
The human race doesn't deserve nuclear power and never will.
There is no singular human race you idiot
Bro, you don't need a crazy operator doing something stupid to have this be a bad design. What if there's a programming glitch or an electrical failure that causes the rods to lift out en masse when they shouldn't? The computer was programmed to automatically SCRAM if it detected this happening. It would be fricking over. There's no word in which "if too many control rods are removed, the emergency stop becomes a detonator" is anything other than an objectively terrible design. The Soviets using the operators as a scapegoat was them throwing copium into the reactors because they still had 12 others in operation and didn't want the populace to revolt against them out of fear.
The fact you think there could have been a programming glitch is hilarious , everything in the plant was most assuredly analog
It was 1986, there was absolutely a computer monitoring the reactor doing state-of-the-art automatic control. In fact they had to progressively disable more and more of the computer to keep the experiment going because it didn't want them to keep removing control rods in their attempts to purge the xenon poisoning. Also, the fact that the computer could only return a reactivity estimate once per 5 minutes was a big reason they exploded, they were accidentally provoking huge reactivity surges faster than they could get data to recognize it.
Fricker we have plants built here in the us after chernobyl was built and even those don't have "digital monitoring" you are talking about
Yes plants have digital components now and computers and shit as part of the operations but none of the mechanisms of shutdown are controlled via computer program
Shits all analog friend
your last sentence is why nuclear power needs to be utilised minimally as a necessary evil
not a single plant on earth adheres to that statement
what a fricking moronic statement
should motor vehicles be utilized minimally because somebody could choose to drive one sidewalks and use pedestrians as speedbumps?
basing decisions around human inclination to resort to chimpanzee behavior gets you stuck in the pre-homosexual habilis era
we have traffic laws , traffic police ,state mandated testing ,state mandated insurance ,federal licencing bodies ect ad nausium
precisely because what i said is true
now pretend a causes consequences that can last in the hundreds if not thousands of years
cars have seatbelts airbags mandated safty functions and limitations independant bodies and company guidelines ect ect ect
you know what anon
i wrote out a reply for you and then deleted it because i realized nobody is this moronic
you planted some superb bait
well done
and if this is your genuine opinion, i hope you never pass on your subhuman genes
the fact remains cars are absolutely made with chimpanzee behaviour in mind
Road legal cars are different from track cars for a reason
if a car is to fast its illegal to even insure let alone drive on a public road
safety standards and even roads themselves are designed knowing people are moronic
look into road signs for 30s and you realise they are designed to act on us subconsciously because people are moronic
and to top it all off minimal use of cars is absolutely the correct standpoint by any metric
"walkable citys " ect are being built globally at the tune of trillions public transport is subsidised to the tune of trillions ect ect
It was the dangerous reactor and too big to have a containment and the nuclear station engineers proceeded with a dangerous experiment at all costs.
Fomin, Why did this anon get trips?
He didn't. Nonzero digits are impossible to get on Cinemaphile.
>Now there you've made a mistake
>Because I may not know much about dubs, but I know a lot about trips
The Soviet way
wtf
impressive, very nice
Comrade Anon, I award you Hero of the Soviet Union. Now regrettably I must ask these men to escort you and they will ascertain the means by which you were able to accomplish such a feat.
how does one acquire this power?
Not from a BWR
mwah
Hey, guy, what the FRICK.
Check out what I got.
masterful
Too much pressure builds up in the reactor.
/thread
How can there be excessive pressure buildup when the system can be SCRAMed whenever things get out of hand?
Did you even pay attention? SCRAM slams all the control rods balls deep into the core which stops the reaction and the neutrons whizzing around.
In those Soviet RBMK reactors, the control rods were graphite-tipped to save money. Graphite doesn’t slow or stop the reaction—it accelerates it. So when those idiots had poisoned the core with xenon and were producing like 100MW, they removed all the control rods at Dyatlov’s orders, overrode the computer saying not to do what they were doing, the increased reactivity boiled off all the water, burned up the xenon and then they had a runaway reactor going crazy.
As the reactor got up to 33 fricking thousand megawatts, they pressed the SCRAM button. This inserted the control rods to stop the reaction, but first, all those graphite tips went in first, causing massive acceleration to the reaction, broke the channels of the control rods with the rods stuck in mid-position, etc.
SCRAM effectively worked as a detonator here because they fricked everything else up so bad.
>Press EMERGENCY STOP
>In 0.5 seconds, the reactor power increases from 500 MW to an estimated 300,000 MW
how do you respond without sounding mad?
“We did everything right”
> N..no..you are.
blessed thread
>the control rods were graphite-tipped to save money
That's the one part I didn't get. Wouldn't putting literally-nothing on the tips have been even cheaper as well as safer?
Lies.
It was the CIA. Didn't you see the glow?
We're up to something here.
Why do Russians call themselves "Gremlins?"
Az-13 malfunction
you're all hysterical hotheads
get yourselves to the infirmary
>Wearing my best cowboy boots and hat, feeling cute, might hand-start a prompt-critical nuclear chain reaction in front of my besties later

kek I love these
Reminder that there are 8-9 RMBK-1000s still in service
Made sensibly and to spec probably fine
BUT
>someone had the brilliant idea to cut costs and build things with alternative materials
>That someone probably wasn't a chemist or nuclear physicist or nuclear engineer
>Shocked when something goes wrong
We see it every time in those china LiveLeak vids, well no fricking shit you should use an inert gas where possible
Shit randomly explodes when you cut costs
wtf did I just watch?
assisted trans suicide
They were supposed to land on a trampoline
They probably landed with so much force some form of friction created a spark and the spark lit the flammable compressed air in the trampoline
it's fake moron
spicy rock makes hot water which in turn spins generators to create electricity.
I wouldn’t explain it, I’d listen and that’s what no one did.
Humiliation ritual
Why don't they just shoot the guys with radiation poisoning that severe? It's impossible to come back from that. They're dead men. Give them a lethal injection instead of keeping them alive while their bodies rot from the inside out.
Ouchi!
That guy probably had the most painful death in all world history
Poor bastard. 83 days of it too
what kind of kinos would you watch?
That's impossible.
If it's impossible, why is there graphite on the roof?
Communism.
If you do real research into the RBMK attack you'll find a certain western governments intelligence agency was behind it...
>The decision to use a graphite core with natural uranium fuel allowed for massive power generation at only a quarter of the expense of heavy water reactors, which were more maintenance-intensive and required large volumes of expensive heavy water for startup.
>ll RBMK reactors underwent significant changes following the Chernobyl disaster. The positive void coefficient was reduced from +4.5 β to +0.7 β, decreasing the likelihood of further reactivity accidents, at the cost of higher enrichment requirements of the uranium fuel.
so the RBMK reactors are actually better than western ones when it comes to economics... and chernobyl only blew up because paranoid soviets kept the flaws secret from the operators.
>3 mile island: melts down, no exposed core
>Fukushima: melts down, no exposed core
>Chernobyl: melts down, blows it's lid
Even disregarding the fact that the Soviet politicians ironically trained their operators wrong on purpose as a joke and that the operators did a little trolling on the night of the explosion, the RBMK design is inherently less safe and more prone to instability/accidents than HWR and BWR designs. It's inherently less safe because of things like the positive void coefficient, which by their nature provoke positive feedback loops whenever the reactor enters a dangerous state. Yes, it is cheaper. No, that's not a good argument. A nuke plant isn't something you cheap out on because if it explodes it renders your country permanently uninhabitable. This is similar to how you don't cheap out on a hydroelectric dam, because if you do the surrounding countryside is totally destroyed when the dam inevitably breaks.
very carefully
like this
>all those spicy rocks
who made these
not sure but I have a bunch
