If you think about it, most if not all serious accidents were caused by carelessness or negligence one way or another.
I think that’s the very definition of a accident.
# an event that happens by chance or that is without apparent or deliberate cause.
"the pregnancy was an accident"
There aren't too many examples, but I think you could've gone full definite on this one. Even Fukushima, whose staff acted heroically and selflessly trying to contain the disaster was irresponsibly located and spec'd falls under your umbrella on that grounds!
Also the control rods at Chernobyl were tipped with graphite. most of the control rods were taken out during the test, so when they hit the emergency button most of the control rods were inserted, and the graphite tips accelerated the heating of the core instead of cooling it, causing the explosion
It was typical for RBMK reactors to raise power output for a short time when the control rods were inserted. Plus - the attempted test was never done successful on any RBMK.
@@stanislavczebinski994 while it was typical for that, not many people know that as the document where that was noted had that part censored by the KGB so it was not well known (source: HBOs chenobyl show)
@@greendaykerplunk IDK for shure were I came across this info first but I guess it was a German tv show.
That’s very true. The AZ-5 switch caused that not only at Chernobyl but also in Leningrad several years prior if I’m not mistaken. This was a faulty design that was very well known in the RBMK-1000 reactors but kept from even those that operated it.
@@wolfbassgames1244 yep, a serious design flaw, that was kept secret by the kgb bc the reactors were already built everywhere in the country.
K-19 was actually one I heard about. It's a required subject to know in submarine school
There's a Harrison Ford movie k19 the Widowmaker
Vasili Arkhipov, was an officer aboard the sub that almost launched a nuclear torpedo during the Cuban missile crisis. Though Arkhipov was just second in command on the boat and launch only required the captain and political officers approval, Vasili out ranked them as the chief of staff for the flotilla, which along with B-59 included B-4, B-38, and B-130. Arkhipov overrode the captain and political officers decision to launch. The bit that is scary is he didnt even need to be on that boat, he just happened to hop on that specific boat to accompany the fleet. Earlier in his carrier Vasili was also deputy commander, essentially XO, of K-19. He had first hand experience what relatively tame nuclear accidents could do, and knew launching that torpedo would have caused a nuclear exchange. Vasili Arkhipov saved the world from nuclear war, directly. And deserves to have his name known around the world.
@@mandi8345 I know of him. It's fortunate that his head was the cool one during the CMC.
That's cool! NSS & BESS?
The problem with nuclear power is human incompetence
US reactors are now impervious to almost all human error and with containment buildings no radiation will ever be released from a nuclear accident.
The Three Mile Island segment of this video has some dangerously incorrect facts. The operators didnt know what was happening. At least not for hours after it started. Almost all the radiation detected was missreported at incorrect levels and they never reported that the type of radiation that was released into the air only had a half life of 6 days and couldn't be absorbed into organic material.
It's not the only segment that was wrong, the Windscale one had a few inaccuracies as well.
I'd take a lot of what these guys say with a pinch of salt.
True. The operators did not know, but they did make errors but the info about the release of radioactivity were incorrect.
@Duck Hunter do you see the world we're living in? There are people who still believe the earth is flat.
Spot on. A lot of alpha and beta radiation has been set free - which is obviously far less dangerous and faster decaying than gamma radiation.
It was years before I was born but the mass hysteria was completely out of proportion to the accident.
Uh oh, not a good look
I grew up near a nuclear power plant in Newport, MI for most of my life…didn’t find out there was an “incident” with the Fermi 1 reactor until I was 30 lol…the accident happened wel before we lived there but it was still surprising…
Ya, every single government hides facts about these situations.
Of all the things mentioned in terms of nuclear accidents there's one that a lot of people aren't aware of but is not talked about and that was the SL1 reactor accident.
True
For the Windscale accident, it is said in the video that workers tried to circulate fresh coolant and the video shows workers pouring water into a tank. Although it is true that the reactor was eventually flushed with water, the reactor was actually air cooled. This is also why Windscale has these big chimneys: You need to get rid of all the air which went through the reactor. The big filters on top of the chimneys are a very distinct feature of Windscale (which almost didn't exist if not for one person fighting the filters to be installed).
Cockcroft’s Follies ❤️
You missed SL-1 reactor steam explosion in 1959 at the Idaho National Engineering Laboratory. 3 service members were killed. Written up in Popular Science magazine in 1960.
I’m pretty sure it was actually in the first few days of January, 1961 is when the disaster happened, unsure though.
@TeneX stories it was an accident. The military just likes to blame quality control, procedural, and organizational failures on personnel rather than actually take accountability for their own failures.
An operator did it on purpose because the other one was cheating with his wife.
@@hardatak Allegedly. There was no evidence to support it other than the fact that the wife of one of the operators had called that night asking for a divorce and he had slept at a friend's for the past few nights. He and another operator hated each other and that was the basis for the alleged affair.
Teacher Mistake: Oops.
Police Mistake: Oops!
Nuclear Physicist Mistake: *Oops...*
Haha yes
My mistake when my dad asks me to grab the belt:
lol
Nuclear physicist MISTAKE: FU########
I actually live extremely close to the Chalk river laboratory. My sister worked there for 2 years as well and the story from those who were there are absolutely insane.
And it's still the safet method in making electricity
Nowhere near Sellafield. The British Isles was minutes away from becoming radioactive, and what is more parliament would not sanction filters for the tower, but were fitted despite the brats in parliament, and because fitted we had a lot less contamination than would have been. Children were cancered, babies deformed, an entire area of Windscale is still radioactive, from 1956. Had the workmen not be able to remove the spent core we would be glowing for a few thousand years, along with nearby countries.
Bonus points for the orchestrated Sellafield/Windscale name bait and switch to try to separate the two.
Yep, they made fun of the guy who wanted those filters (John Cockroft), yet he persisted and had them fitted. They still made fun of them and called them Cockrofts folly.
Little did they know, those filters captured enough airborne contamination that could have reached past eastern Europe.
If we focused on efficiency instead of moving on to the next thing, things would be greener.
@@srjwari perfectly worded. We should always strive to be better than we were yesterday, but never to the extent of regression.
When it comes to nuclear meltdowns in America, most people think of three mile island, but the SRE and SL-1 are two serious accidents involving nuclear reactors that took place in the United States that very few people know about.
The sodium reactor experiment (SRE) in 1957 released many times more radiation than three mile island.
I didn't know about this. At about the same time in 1957, Rocky Flats in Colorado had a plutonium fire which spread plutonium dust throughout the Denver Metro. Of course, just lke SRE, it has been swept under the rug. Very few people know about Rocky Flats today.
@@j50wells Rocky Flats also had a second major fire in 1969, not to mention scads of negligent practice over its entire history in dealing with waste products that contained plutonium.
The SRE was part of the Santa Susana Field Labratory outside Los Angeles. That facility also had a bad history of dealing with radioactive containing wastes, one of which involved rolling barrels of radioactive sodium into a pond and then shooting the barrels with machine guns to get the sodium to mix with water, in which it reacts and explodes violently, sending toxic radioactive smoke wherever the wind blew.
I knew about these they were conducted by the military
Or Fermi 1 near Detroit.
My first thought was SL-1 too. I didn't know about the SRE, thanks for bringing it up. :)
You should do a video on the time a titan 2 missile with a nuclear warhead exploded in its silo in Arkansas almost taking out the state’s capital
Most of all nuclear accidents ever could've been avoided by weekly audits.... Negligence kills most
The audits don't matter if the people running it don't take them seriously
Weekly audits? R u kidding me. The reactors and containment buildings and thick steel are inspected all the time. In the US anyway.
@@kadenwolf5798 operator error back then disproves that
I love your videos keep it ❤
Keep making these we keep subscribing
always look forward to infographics shows thanks for making them
And it's still the safest most efficient form of energy generation.
Most efficient, clean and safe form of energy generation to replace the truly deadly fossil fuels
Yep
Yes!
a bit of the info they put out is just plain false. Mainly about TMI, makes me want to research the rest to see how off they were about those too
@@nomoideas yes. False in that radioactivity was released as a result of the hydrogen explosion when in fact it did not breach the containment building.
I live a few hours from
Chalk river on the Quebec side, couple of years ago we got a false emergency alert from a reactor meltdown at chalk river it threw most of Ottawa into panic
“It is my firm belief that the infinite and uncontrollable fury of nuclear weapons should never be held in the hands of any mere mortal ever again, for any reason.” Mikhail Gorbachev
Me thinks we have here a nuclear boogie man propagandist. Ban fossil fuels, and nuclear, but keep buying them expensive CCP, inefficient solar panals, aye comrad?
This is no weapon, its an infinite source of electricity
@@anonymous-go1tq Nuclear reactors are in no way a weapon. That's not even how they work. Even if you wanted to use them as a 'weapon', you would have to spend millions of dollars, and multiple years in a enemy nation, and then melt it down on purpose. For that amount of time and money, it would be far, far easier to make any of the other weapons we have. To make this clear, nuclear reactors are not bombs, they don't even explode. There is a reason they are called meltdowns, its because that's what happens, the intense heat melts the containment area. The only reason there are 'explosions' are because of the buildup of pressure from steam, the same steam that is used to power the majority of all energy we use. Coal? Natural gas? oil? geothermal? all use steam. using water is the way we power our society. Sure there are exceptions, such as solar, and wind. But even wind uses a turbine, just not steam powered. To be clear, there are more deaths from wind power, and solar power, than nuclear power. And that is INCLUDING all the accidents. People forget, that to get solar panels, you need materials that are mined in hazardous locations, underground. The construction of wind farms requires tons of materials, along with the location, which is IN THE AIR. Nuclear power costs a high upfront cost, and takes a long time to build, but it is 100% worth the wait.
rant over.
@@anonymous-go1tq calm down buddy
@@anonymous-go1tq Nuclear weapons are bombs. Nuclear reactors are dangerous power sources, not a weapon. A nuclear reactor is as much of a weapon as a car is, it depends entirely on who is using it and how well they know it.
True facts, a nuclear reactor cannot turn into a nuclear bomb, there can be an explosion but this could be due to over pressurized vessel, no coolant, and other things
3% uranium enrichment for reactor grade, 90% enrichment is required for nuclear weapons.
@@kadenwolf5798
And a reactor has a moderator and control rods. Both these things would defeat the entire purpose of an A-bomb if present in said bomb.
@@swokatsamsiyu3590 also, instead of the atoms blowing the vessel apart in a nuclear weapon, the energy of all the atoms is released at once before it has the chance to blow itself apart.
It's a little higher than 3% for commercial reactors.
@@averagejoe112 every lecture I've had says around 3%.
I would argue 3 Mile Island wasn't the deadliest Nuclear Accident. Yes, there was a meltdown, but i wouldn't say it should be on the list since the cooling system was fixed and the levels of radiation are not believed to be dangerous to humans or nature.
Sellafield overtook this, and was minutes away from lighting up the British Isles
Literally zero people died from TMI.
SL1 was a small incident but it 3 people died as a result I'm shocked it is so unknown I'm disappointed it wasn't mentioned
@@erelahaster4276 or the Demon Core
@@erelahaster4276 I mean only 3 people died
I loved this you did a great job
Come on,they weren't that bad, lets build more reactors, so we have practically clean energy
😎And let’s let the lowest bidder build them
If they are built using modern tech then even if it "melted down" it would only need to be shut down for a little bit of time
Just so they're not RBMKs, and we don't put the generators and their fuel supplies where they can be ashed away by a tsunami.
Yes we should build more at least the work when the sun is down and the wind isn’t blowing.
All the scenarios described are impossible with gen 3 reactors. Nuclear power is safe.
My grandad was in the National guard at the time he was an officer for logistics Pennsylvania one day he got a call for three mile island. My grandma went with him. I don’t remember the next part of the story but one night while he was still wearing his dress uniform. He met my grandma at the hotel pool and a lady started panicking thinking they were all their to evacuate the area.
The funny thing about 3 mile Island is that nothing happened. No one died, no one was injured, and not enough radiation was released to increase the local radiation levels. The safties on the reactor worked. And all that actually happened was a massive media panic lead entirely by the media. The government didn't even know why everyone was paniced because the media made up a bunch of stuff about the incident before the government even had time to say anything about it.
Oh yeah i know of a video thats very accurate on what happened at 3 mile Island. If you want to watch it ill tell you.
Great vid
Well, that was an amazing video! We want more like them
bro the vid came out 6 minutes ago how tf have you watched it?
dont speak for us
Yea, no. This video is not so good, because even tho the information is correct, it is pretty misleading with regards to the safety of nuclear power, which is the safest energy source, and the facts concerning global warming and how fossil fuels are killing both the planet, and loads of people.
But I'm responding to a bot comment, so it doesn't matter
It's also incorrect on many points.
Look up a video series called Half Life Stories by Kyle Hill for much better and accurate information on most (if not all) of these.
@@ozrithclay6921 His videos are A1 for sure
Yet nuclear power has caused fewer deaths than coal. If I had a choice of radiation poisoning or silicosis I’d chose cyanide
I'd choose chocolate.
Yes. This is correct.
It's still the safest form of energy per kw. Even safer than pv panels
Homer: “Mmmmmmmm! Nuclear reaction!!”
Just wanted to say, this was a great vid, however there have overall only been very small amount of nuclear power accidents and the death tolls of these experiments are very small in comparison to accidents in hydro electric, wind and solar. The power output of these plants in comparison to other energy sources, like renewables is far outweighs the dangers of a reactor meltdown. Also most bad nuclear accidents were caused by human error, fear of superiors and overall people and their negligence.
also we use safer thorium instead of uranium now which can’t put out energy without plutonium which makes it much safer in event of an accident
The benefits of nuclear power far far outweighs the risks. Sadly, the general public isn't well educated about nuclear energy, and most of what they do know is negative. They also don't know that a redicilous amount of people who die each year, die for causes related to harm from fossil fuels (I think it's like 1 in 50 deaths!)
If we ever obtain the ability to gain stable energy with Fusion rather than fission, we'll have a chance of saving ourselves.
On top of that, non renewable renergies, which are the ones that nuclear is supposed to replace, kills millions every year, no accident required. A coal plant even gives more radioactivity than nuclear plants, becuase the burnt coal contains traces of many elements, including uranium, which is dumped into the air. That's why radioactive levels are higher next to coal plants than nuclear plants, ironically.
@@jessicadent5944 so fission is where you split atoms and fusion is where you combine them correct
@@Hunter-mj8qg So first, disclaimer. While I find nuclear energy (and disasters) fascinating, I am far from an expert..
So to the best of my understanding..
But yes! You have it correct.
Fission is the splitting of the nucleus releasing energy, this is definitely more dangerous and can actually happen in nature (given the correct situation) 😱
Fusion is more difficult, and in fact we've yet to actually be able to produce usable energy with it. But Fusion is kind of the opposite of Fission is the fact that you're combining two lighter nuculuses? Nuculi? Whatever the proper way to word that is.
Woah very interesting
i used to live in petawawa near chalk river, and had family friends who work at the plant they make bank working there and the nuclear accidents are constantly brought up daily 😂
I love how the title says "most deadly" yet with most of these no one died, at least directly
the infograghics show have you done a story on Three Mile Island? BC I am doing a history project on it
Thumbs up for correctly pronouncing Goiânia, since Portuguese tritonges are tricky even for native speakers. Also, Goiânia incident being on par of biggest nuclear accidents is more than right. The junkyard owner sold lots of Cs-137 pellets to people because they are little, shiny blue spheres and looked beautiful. Still today people from Goiás (Brazilian State of which Goiânia is the capital city) suffer from this event, which was caused by carelessness and greed.
On a list of "Most Deadly Nuclear Accidents" how can you include 3 Mile Island which literally killed nobody?
Can you do the rockodyn incident in Simi Valley?
Hmm. Winscale pile didn't have coolant as it was cooled with air.
The nuclear plant in Ukraine is going to be on that list if Russia, and Ukraine do not stop fighting around that area
And Chernobyl itself almost had an encore earlier in the war lol.
Well, one of the very earliest nuclear accidents involved a prototype atomic bomb core, the so called Demon Core. It seems like a couple of scientists were careless about putting that core together or experimenting with it. The first one liked to "tickle the dragon's tail", as he called it; he held the two halves apart with the head of a screwdriver while seeing how close he could get to criticality.
Well, one day, the screwdriver slipped, the ball came together and went critical, causing a radiation flux that killed the idiot playing around with the screwdriver and the core. Ooops
I think the second careless scientist might not have been watching where the graphite blocks around the core were being put. Whomp whomp. Another criticality accident, and I think someone died from that one too
I think they need to verify the reactivity of the hemispheres before they can be installed in a bomb, it's not just for fun.
As I recall, it was the core which would have become the third nuclear weapon dropped in Japan if needed.
Nice
your information on the 3mile island incident was wildly inaccurate, makes me wonder how wrong the rest of the information you presented in this video was.
The name alone sounds very cool
On the daily grind love the content keep up the work
just find this one fact intresting on the uk reactor kinda looks like an RBMK type reactor
I honestly think we go with solar and wind power but atleast this can be better then fssil fuels
Nuclear power releases less radioactivity than coal power plants. U can fact check that.
The K-19 story was made into a movie starring Harrison Ford and Liam Neeson.
Qui-Gon Jinn and Han Solo.
K-19 was known as "The Widow Maker" by the Russian sailors
Lets go New vid
Windscale accident was so bad they literally waited until now to decommission the nuclear reactor, and they're right to wait as they have concerns that the fuel rods are still hot.
What about the accident at the Santa Susana Field Laboratory outside Los Angeles?
Thank God for such a bright and calm human being as Jimmy Carter.
Every video about nuclear energy should first mention that it has saved 1.7 million lives and that it’s one of the safest energy sources
3 mile island was literally revealed to be the least deadly nuclear disaster to ever happen. I genuinely recommend researching any information stated in this video before coming to your own conclusions.
WRONG troll you want us to lower our guards to get your way! Nobody is committing suicide here! NO ON NUCLEAR!
16:41 "do not entry" lol
Windscale was an air cooled reactor the uranium at the rear of the reactor wasn't receiving proper air flow and or receiving hot air that's why the the rear of the reactor caught fire
I bet it wouldn’t be fun
Your description of the events of Three Mile Island is surprisingly inaccurate. It's worth reading up on. Don't contribute to the lack of understanding surrounding nuclear accidents, it's stifled the expansion of nuclear power for too long.
The good aspects of the technology aren't to be dismissed lightly, but it is certainly wise to be wary of it.
I just don't think nuclear weaponry should exist, or at the very least, should only exist for planetary defense.. if they could even be viable for that.
Well this video is not about nuclear weapons. And the Uranium used in reactors is 87% less enriched than weapons grade uranium.
3 mile had people who didn't know what they were doing. The unit was only 3 months old.
No one knows truly how safe they are unless you work at one. I've been on this same job decommissioning and tearing down a nuke plant. Crazy how much monitoring check and steps that have to be done just to get anything out of certain rooms much less the building. There are so many precautions that are taken dealing with nuclear material.
I agree, the public has an irrational fear of nuclear when it’s the least harmful (to people and environment) way to generate power. Once their fear of global warming and rising oceans becomes greater than their fear of nuclear, we might finally see some progress.
@@Sniperboy5551 We can only hope.
@@Sniperboy5551no. We don’t troll
I got a video for you. Dinosaurs vs Modern day humans. our technology, weapons, dogs against Dinosaurs. I believe humans would wipe them out again. snipers, himars, tanks, jets, rocket launchers, grenades ext dog packs
We need more vids on advancements with tech and health care to deal with old lingering problems like these. With the new tech today and in the future these accidents can remain in the past and the whole 3 mile island accident shows that if the owners are lying that much it is a cover up and the truth must come out or else there will be riots.
TMI reactors were gen 2 not gen 3 and no radioactive gases escaped from the containment building at the time of the hydrogen explosion, it was released over 2 weeks because the dissolve factor was so large that anyone near a city near the powerplant recieved 1 millirem of radiation. Those closest directly downwind of the plant recieved 80 millirem. Trivial but no where near as bad as Chernobyl. There were no additional cancer deaths because of TMI nor any other issues.
Also, our gen 3 reactors have hydrogen absorbers to guard against that particular scenario.
I was expecting to see he worlds first nuclear meltdown, the SL-1 event, would have been in this video.
Granted, with only three casualties in that one (as far as I know), I don't think SL-1 would qualify for this video.
I live in Canada and I’ve never heard of chock river
16:43 ah yes do not entry😂
“If the core reached 5,000 degrees it would explode and send radiation across the country.”
I’m…I’m pretty sure that’s not how that works. Like, at all.
Seems like a lot of highly inaccurate information being stated as fact in this video. Bad move, dude. You have responsibility to be as impartial and truthful as it is possible for you to be. However, either poor research, a lack of credible sources for you, or just plain old falsehoods, have shown you up
well now you know why Canada went Hydro and thermal now as well
March 28th is my birthday lol. Plus I only live an hour away from Three Mile Island. Happy my state is on here for once.
In Mayak, it wasn't a reactor that exploded, the explosion happened in a spent fuel storage facility.
with the Chernobyl, adding on to the other comment, as the graphite tipped control rods went all the way in with A3-5 being pressed, it caused every bit of water in the water cooled reactor to turn into steam adding pressure extremely fast and with A3-5 pressed and all cooling stuff down, the control rods wouldnt be able to pull back up and it blew the lid off first, then with the very very VERY hot graphite with hydrogen combining with the rushing oxygen is what made it really have that famous explosion, not just the pressure.
Core was also poisoned due to operator error
The two workers at Fukushima did not die from radiation. They died because they were inspecting the basements of the generator buildings when the tsunami stuck the plant, it flooded the basements drowning the two workers.
I have the feeling that nuclear reactor control rods often jam.
K-19, the backup system was designed, but was never installed despite the controls still being available in the control room. Only one reactor was damaged not both. The fear was the core would melt through the reactor and cause a thermal explosion near the NATO base at Yan Myen which could spark a war. People had to go into the reactor late containment vessel and link the freshwater stores into the reactors coolant loop as the coolant was just distilled water. Since the reactor seal was irrevocably broken as a result of the repair the radiation was released throughout the sub. They actually had to repair it twice as the initial repair failed.
They waited and waited while the reactor got severely hot then Boom!!!🤣🤣
what about the sl-1 disaster?
Research, and the mistakes learned at chalk river led to the development of the CANDU design reactor.
You forgot to include the santa Susana field laboratory disaster
No rocketdyne ? Figured that would explain why everyone from Simi Valley is so weird
not any mention of SL 1?????
You missed UK Sellafield
The three mile Island accident was bad but the media over reacted to it.
wow
Nuclear energy has the highest reward but also the greatest risk.
The risk in US reactors is almost 0.
the average brown coal plant has 32.72 deaths per TWh and nuclear has, guess what? 0.03 deaths
“All videos are based on publicly available data…” sooo that explains the inconsistencies 🙃 *cough* Wikipedia
One eye open up and sleeping
I like this channel but there seem to be alot inaccuracies portrayed on it. I guess thats why its called the infographics SHOW
The fact TMI even made this list is surprising. Even in the video they point out there is zero conclusive evidence that any harmful effects came from it. TMI was a PR disaster not a disaster that caused contamination.
Kurtzegast fans: *Hey, I've seen this one before!*
Just finish wacht HBO 'Chernobyl' yesterday for second time
Bro…. When he said “tWisT” I felt it in my soul bro……
I thought most deadly?
No one died in 3 mile island and there’s no real elevated level of cancer in area. That reactor all was still used and worked until 2019.
They need to learn how to keep dem dang fuel rods cool
In the US if the water all goes out the chain reaction stops and the emergency core cooling system kicks in and cools down the core. We also have hydrogen absorbers to guard against hydrogen explosions like happened at Chernobyl and Fukushima.
There is a lot of misinformation in this video. I'd recommend pulling it down and tightening up the information and reposting.
and that’s why we should use thorium
No. Do you know the difference between reactor grade uranium and weapons grade uranium.
