meltdown at 3 mile island

[captinseperoth]

yet unlike this accident which was all hyped up, and primary all bark with no bite...

We had several MAJOR Fly/bottom ash. These ashes contain toxins which include

arsenic, beryllium, boron, cadmium, chromium, chromium VI, cobalt, lead, manganese, mercury, molybdenum, nickel, radium,selenium, strontium, thorium , uranium,thallium, and vanadium,along with dioxins and PAH compounds.

These major acidents happened in the years

2008 1.1 billion gallons ash sludge

2000 306 mil

1972 132 mil

[lendir1]

I was in junior high at the time the announcement came over the intercom about 3 mile island, just 5 miles away. We could see cars speeding into the school parking lot as parents ran through the halls looking for their kids, by the end of the day we averaged about 3 to 4 students per class, we just sat there.

[wow0806]

you would of thought if like 50 alarms went off the rods would be deadlocked into the core to stop teh reactions?

[megaman2000]

@wow0806 depends if the core was past the point of stopping.

[njamlv]

ahhh god im 12 years old an i know that when the nuc core gets over heaten it melts down so u dont turn off the frigging cooling system ... GOD...

[BigKleib34]

haha description says 1978 first words of the videosay 1979..just to be an ass

[Doggieman1111]

it's too bad that these major malfunctions happened. nuc power would be great if not for silly humans making it dangerous.

[wks1978]

Nope. It aint natural

[thisissick22]

the sun? not natural lol

[wks1978]

Who mentioned the sun?

Are you sure you left this comment on the right video?

[thisissick22]

didnt you say it wasnt natural?

[wks1978]

What on earth are you talking about?

I said splitting atoms to produce power isn't natural. You're the one who mentioned the sun.

You must be on crack.

bye

[thisissick22]

yes, the sun was natural last time i heard. and i think its safe to say it produces energy.

[wks1978]

We seem to be having 2 different conversations here.

anyway, the sun does produce energy, but that doesn't mean we have to mess everything up trying to harvest it

[thisissick22]

i brought the sun up, as you seem to believe that a nuclear reaction isnt natural. as if that is any reason not to generate power from it anyway. is burning fossil fuels natural? is using electricity natural?

[wks1978]

Using electricity is not natural because it was not created by evolution.

Nuclear reactions are natural, but splitting Uranium atoms is something that does not happen naturally in our environment. We have evolved to exist in particular envrionment, not one where lethal doses of ionizing radiation are present.

Burning fossil fuels is not natural as they naurually exist under the ground.

Ask anyone with any intelligence

Anyway, I'm thorough arguing with you.

Move to a proper country

[thisissick22]

mmm, well you seem to have succeeded in writing a long post, that doesnt actually make any points. you're either saying we should utilise things which are not natural, or the opposite...

nice touch with the personal insult at the end. very intelligent.

[wks1978]

oh dear.

Just think, we drove the Nazis of the channel islands so this idiot can have his freedom...

[thisissick22]

its clear you dont know much history, let alone science. firstly, the germans were never driven from the channel islands. no fighting ever took place here. second, "we"? who is "we" because i doubt very much you played any part in the second world war. honestly, what a moron you must be.

[wks1978]

If you want an argument, go and fight with someone else.

You know nothing about my educational background and you have never met me in person.

Go and pick a fight with someone else.....

[thisissick22]

ok, goodbye.

[THEFINALHAZARD]

@wks1978 Everything you said was correct EXCEPT your first sentance!!!! Electric eels produce electricity, so...

[schusterlehrling]

@wks1978

Well, it is as physical process that is done in nature billion and billion times.

What dom you think the sun produces?

Energy.

Without "electricity" or rather "energy" you would not exists.

Simple as that.

[MidgardEagle]

Wearing clothes is not natural because it was not created by evolution.

Urinating in toilets is not natural because it was not created by evolution.

Diving is not natural, as we have evolved to exist in a particular environment, not one where there is not enough oxygen for us to breathe.

[your last statement was just too stupid to parody]

Ask anyone with any intelligence.

[DrBPhD]

@wks1978 The sun is a big nuclear reactor. It produces energy by fusion, not fission like man-made reactors but, but it is in fact a natural source of nuclear energy. Safe? Well, lay down on the beach for one long hot summerday without any sun-lotion and you will notice. And if you try this day after day every season for a number of years you are likely to end up at a medical specialist for skin cancer.

[DrBPhD]

@wks1978 And btw, burning fossile fuels brought up from deep underneath the earth is in fact less natural than nuclear energy and not necessarely safer.

[dwetick]

Nobody was killed at TMI, you idiot!

[tonip420]

thats what i said.....idiot.....

[Simyonez]

no u didnt

[dwetick]

The Modern Marvels episode of TMI is no longer available.due to its controversial re-enactment. The beaker of core water that vibrated in your hand was too terrifying to imagine but was nevertheless true!

[Kacknap92]

lol.. the china syndrome makers could look ahead in future :S too sad

[chickendec]

i just saw this in my chemistry class.

[erich84502]

Chernobyl was a graphite reactor.

[mynewid666]

I guess my main problem with nuclear energy is that uranium comes from australia. We have the tailings dam from one mine leaking 100000 litres of radioactive water per day into the world heritage Kakadu area. And the potential for terrorism using a dirty bomb increases when such materials are produced as byproducts of uranium mining. As an alternative, it is no contest between nuclear energy and just using less. Consumption is the problem, so reduce consumption.

[mkarnerfors]

mynewid: What does the Australia's health- and e`nvironment government agencies have to say about the uranium mining operations? They are the ones in charge of monitoring the emissions and effects. What do they have to say about your mines?

[mynewid666]

they say what any good government would say- our environmental monitoring programs are world class best practice programs with incredibly low trigger points ensuring that no problems can ever occur ; )

actually monitoring is generally the job of the proponent (in this case mining companies) and environmental agencies liase or do their own assessments to ensure compliance

[mkarnerfors]

And your argument that the monitoring government agencies are wrong or cannot be trusted is....?

[kalana999]

3 mile island wasen't the worst disaster.

Chernobyl was.

[userroscoe]

Chernobyl was in the world.This was one of them in usa.

[Spyro22475]

Also, Chernobyl incident occured 8 years later.

[userroscoe]

Little do people know simi valley was the worst in the usa!

[jediscar]

Simi occurred at an experimental facility for sodium reactors. I think they were referring to it as being the worst disaster in a COMMERCIAL nuclear reactor. Simi was a 20 mega-watt reactor while TMI was something on the order of a 1,000 mega-watt power plant.

I'm not saying Simi wasn't worse in terms of an overall nuclear accident. I am only arguing that in terms of the commercial use of nuclear power in the USA that TMI was the worst.

[userroscoe]

Ok I give you that but nuclear reactor wise it was the worst in the us!!!

[computersmasher]

i know its amazing how many people dont know about it theres another youtube video about it

[jediscar]

It says at the beginning that it was the worst in the US at that time. Chernobyl occurred in the now dissolved USSR. Additionally, Chernobyl occurred eight years later.

[kakashi76767]

from 0:09 to 0:14

[kakashi76767]

what is that lady hanging up in the beginning? is it a ghost costume, or a kkk mask? wtf? anyone?

[computersmasher]

did anyone notice that meltdown in the title is spelled incorrectly

[mynewid666]

i did but i never bothered to change it, until now ;)

[computersmasher]

just checking :)

[watchingirlz]

@mynewid666  Years wrong to it was 1979

[tiaresmiles21]

this is the most GENIUS comment ever.

:D

snowboardnmtbike:

I love three mile island. I waterski there all the time. My friend and i are going there tomorrow to ski. One time we saw a white turkey in a flock of all black ones. I wounder what happened there? must have been global warming.

[barkkkproductions]

snowboardnmtbike your so funny.

[zenmachinefilms]

I remember this. Depressing times.

A shame though that instead of learning from this and fixing US nuclear power, we abandoned it.

[Vegathetruth]

how did we abandon it? TMI's accident helped all nuclear plants across the globe. It sent higher standards and safety issues for all plants and everything was accounted for in TMIs accident.

[milofonbil]

"everything was accounted for in TMIs accident" Nonsense. On another video commentary you finally admit to the fact that 2% of the uranium is not accounted for. Were you on this video tape, Mr "Director of Engineering at Entergy"? You did claim to be there working at the plant after the meltdown. Liar.

[milofonbil]

How come on another video commentary you admit to the fact that 2% of the uranium could not be accounted for?

[nursewolf]

I'm sorry this situation was unfortunate, but i still feel strongly that nuclear power is still a very feasible option for the U.S. to explore in combination with other sources. Take the lessons learned here and apply them.

[8145551212]

The operators INTERVENED because the management hod told them to shut down ECC as soon as possible! It was a Management failure. I am amazed at how many people have this wrong...

[splatwacker]

sucks cus the energy is cheap, and clean if controlled right, but people are mainly afraid of It because nuclear power is synonymous with nuclear bombs... and radiation alike, yet there is only one way to learn about it. Meh, Who wants to do that?

[Vegathetruth]

actually people want you to think that its like a nuclear bomb but thats impossible. A nuclear bomb is small and compact togather. Inside a reactor is huge and atoms clash and break apart from each other fast so it would be impossible to create a bomb from that. Nuclear is here to stay its just a matter of time when the liberals face it and except it

[milofonbil]

No, but reactors can still explode due to human error. And, the "containment" building won't be able to contain the explosion. The reactor will scatter nuclear materials all over the countryside just like Chernobyl, just like an atom bomb.

[Vegathetruth]

Chernobyl had little safety and they were running 4 reactors at once. This is insane and extremely dangerous and I recommend that no nuclear facility try it even though Japan runs up to 6 at a time. Again this was during the cold war and Russia didnt care about the consequences so of course that was the result.

[computersmasher]

whats the point of having 4 reactors if your only going to run 2 at a time, or 6 and only running 3?

[zoolkhan]

you can shutdown for maintenance if you have redundant facilities.

[computersmasher]

the soviet union built chernobyl HALF-ASSED and the people suffered because of it they were in compition with the us they needed cheap energy safety was not a concern and because of it people and animals suffered

[thelight84]

Containment building on a USA reactor is two parts of conceret and reinforced steel tubing. Not even a Boeing 747 making a direct impact can destroy the structure. In Chernobyl, they never used contaiment buildings (they were built like the buildings that house steam turbines), so their reactor buildings had little integrity.

[milofonbil]

There is no proof impact by a 747 would not cause severe damage to a modern reactor with a containment . There are not even requirements to do this. Why don't you read 40 C.F.R. § 265.1101 for yourself.

Chernobyl had a much larger reactor room than do US reactors. In order to build a containment to nearly the same pressure levels 57 lb/sq in, the walls did not need to be as thick. However, no containment building can contain an explosion like Chernobyl had.

[kokoheal]

Iwnf360...your view on nuclear power and it's silent deadliness are dim..to say the least. I hope you get sent off to Iraq, fuck-wit.

[snowboardnmtbike]

I love three mile island. I waterski there all the time. My friend and i are going there tomorrow to ski. One time we saw a white turkey in a flock of all black ones. I wounder what happened there? must have been global warming.

[ed11561]

WOW -I'M GLAD A 22 YEAR OLD PUNK FUCKING KID WAS ABLE TO STOP MY FEARS OF A NUCLEAR PLANT MELTDOWN.SEE lwnf360 above.STUPIDITY.AND I'M GLAD ONLY 1/3 OF THE CORE MELTED RATHER THAN 1/2 THE CORE-FUCKING IDIOT.DOESN'T REALLY MATTERNOW DOES IT?

[milofonbil]

Yes ... 1/3 is a lot less than the 1/2 the NRC reports, isn't it? Besides ... what do they know?

[lwnf360]

The video's claim about the amount of the core meltdown at TMI is exaggerated. The reactor vessel is 14 ft high. Only 5 ft. of the core melted. That is about 1/3. Also, very little molten material actually made it to the bottom of the reactor vessel. There is an excellent video available from Penn State University

Search for: "penn state defueling video" on google and it is the first hit.

It documents the defueling of the damaged reactor in detail, and is the source for my above information.

[milofonbil]

"It was later found that about one-half of the core melted during the early stages of the accident." According to the NRC's Fact Sheet on the Three Mile Island Accident.

Quit spreading disinformation.

[lwnf360]

At Chernobyl the core melted, the reaction stopped due to a lack of a moderator, and the molten core debris gradually cooled. The molten core barely made into the basement of the reactor building. The reactor design at Chernobyl was the largest in volume of fuel, largest in thermal output, and largest in electrical power output ever built. Even in this worst case, the molten core didn't even make it out of the building's foundation. The "China syndrome" has been demonstrated to be impossible.

[milofonbil]

Right. A large part of it exploded. A large part of the core was never recovered and it was strewn all over the countryside.

[lwnf360]

The so-called "China syndrome" is beyond laughable. Reactors in the US (i.e. light water reactors) require water to maintain the reaction. Even if the control rods were not inserted into the reactor when it ran dry, the chain reaction would stop. The molten core would gradually cool even in the presence of air only, since the reaction was halted by lack of water.

[milofonbil]

So how did half of the core melt down at TMI?
