Most Deadly Nuclear Accidents of All Time

Nuclear energy has the capability of powering an entire city's population with power, but one mistake could result in a nuclear accident of epic proportions! Check out today's insane new video to learn about the most deadly nuclear accidents in history.

If you think about it, most if not all serious accidents were caused by carelessness or negligence one way or another.

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.

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

K-19 was actually one I heard about. It's a required subject to know in submarine school

Teacher Mistake: Oops.

Police Mistake: Oops!

Nuclear Physicist Mistake: *Oops...*

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).

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…

The problem with nuclear power is human incompetence

[Anakinmanakin]

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.

[mr.patriotjol]

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.

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.

If we focused on efficiency instead of moving on to the next thing, things would be greener.

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

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.

[bulgingbattery]

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.

Most of all nuclear accidents ever could've been avoided by weekly audits.... Negligence kills most

[elitemook]

And it's still the safest most efficient form of energy generation.

[NINJAKNIVESTKO]

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

[TheDarckwar]

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
