Three Mile Island Nuclear Accident Documentary Film
The Three Mile Island accident was a partial nuclear meltdown which occurred at the Three Mile Island power plant in Dauphin County, Pennsylvania, United States on March 28, 1979.

It was the worst accident in U.S. commercial nuclear power plant history, and resulted in the release of small amounts of radioactive gases and radioactive iodine into the environment.
The power plant was owned and operated by General Public Utilities and Metropolitan Edison (Met Ed). The reactor involved in the accident, Unit 2, was a pressurized water reactor manufactured by Babcock & Wilcox.
The accident began at 4 a.m. on Wednesday, March 28, 1979, with failures in the non-nuclear secondary system, followed by a stuck-open pilot-operated relief valve (PORV) in the primary system, which allowed large amounts of nuclear reactor coolant to escape. The mechanical failures were compounded by the initial failure of plant operators to recognize the situation as a loss-of-coolant accident due to inadequate training and human factors, such as human-computer interaction design oversights relating to ambiguous control room indicators in the power plant’s user interface. In particular, a hidden indicator light led to an operator manually overriding the automatic emergency cooling system of the reactor because the operator mistakenly believed that there was too much coolant water present in the reactor and causing the steam pressure release. The scope and complexity of the accident became clear over the course of five days, as employees of Met Ed, Pennsylvania state officials, and members of the U.S. Nuclear Regulatory Commission (NRC) tried to understand the problem, communicate the situation to the press and local community, decide whether the accident required an emergency evacuation, and ultimately end the crisis. The NRC’s authorization of the release of 40,000 gallons of radioactive waste water directly in the Susquehanna River led to a loss of credibility with the press and community.
In the end the reactor was brought under control, although full details of the accident were not discovered until much later, following extensive investigations by both a presidential commission and the NRC. The Kemeny Commission Report concluded that “there will either be no case of cancer or the number of cases will be so small that it will never be possible to detect them. The same conclusion applies to the other possible health effects”. Several epidemiological studies in the years since the accident have supported the conclusion that radiation released from the accident had no perceptible effect on cancer incidence in residents near the plant, though these findings are contested by one team of researchers. Cleanup started in August 1979 and officially ended in December 1993, with a total cleanup cost of about $1 billion. The incident was rated a five on the seven-point International Nuclear Event Scale: Accident With Wider Consequences.
Communications from officials during the initial phases of the accident were confusing. There was an evacuation of 140,000 pregnant women and pre-school age children from the area. The accident crystallized anti-nuclear safety concerns among activists and the general public, resulted in new regulations for the nuclear industry, and has been cited as a contributor to the decline of new reactor construction that was already underway in the 1970s. Public reaction to the event was probably influenced by The China Syndrome, a movie which had recently been released and which depicts an accident at a nuclear reactor.

Who cares what this wanker has to say. He was fired for his incompetence and now he is an nuclear activist. Big suprise!
in the last month, there have been 2 more accidents at tmi, both releasing radioactive steam! check out my channel 4 updates!!!vincedigiacomoat youtube dot com thank you very much and pkease subscribe!!
7 [SEVEN!!] PEOPLE HAVE NO IDEA OR CLUE AS TO THE ERRORS–MECHANICAL & human THAT =THE WORST COMMERCIAL NUCLEAR DISASTER THAT HAS EVER HAPPENED IN THE GREAT U.S.A.@ 3 MI ISLAND!!
~MORE over, THESE 7 ppl should not even/EVER comment to the rest of us INFORMED, CONCERNED & INTELLIGENT individuals about ANY THING~!~ EVER!
~THIS Video is Facts & informed input THAT ALL OF US SHOULD BE CONCERNED ABOUT! These 'Dis-Liker's: ARE FOOLS !! WE NEED TO BAN EVERY THUMB DOWN 'PLACER' FROM OUR COMMUNITY
The worst nuclear accident prior to Chernobyl. Also by human error combined with technical one.
This is shid

Melting at TMI and the Fukushima reactors was driven by the decay heating power of the fission products in the respective reactor cores. This power falls off rapidly with time because of short half lives; so although the melted material is initially hot and highly radioactive, it has not demonstrated enough energy to get through the combination of the the huge reactor vessel, and the supporting concrete. Finally, reactor plants have to be supported by bed rock to meet seismic requirements.
Randy King is a tool, TMI had a meltdown that was never in danger of leaving the reactor vessel. and that bit where he's throwing around birthrate numbers was hilarious like hes a geneticist. The worse case of misinformation, and fear mongering really. The only thing i can agree with is the management position with the public; its not to give a straight answer unless your threatened at gunpoint, and then negotiate your way out of the question, ridiculous it still happens today no matter the NRC
Uranium has a short half life???
Fission produces a witches brew of isotopes with various half life values. The ones with very short half lives are consumed early producing the heat that causes the fuel melting. The fission products include isotopes of barium, krypton, and adjacent elements in the periodic chart. I couldn't include a web site, but search for "reactor decay heating," and you can find a graphic showing how the heating rate falls off with time.
Correct. If the melt doesn't go through something – anything immediately (like in the first couple of days), then it probably won't do it in the future as it both cools and spreads out.
Fairly obviously, without people there would be no technology. Your tautology doesn't help analysis very much.
FYI at Fukushima the reason of the accident in Fukushima was that PEOPLE gave a shit about security, PEOPLE were lying in the reports. Technology is not something Humanity cannot handle because it's nature, it's not something woodoo!
Nuclear power is like some ultimate evil type of alchemy from hell,, and I can't believe what a terrible thing those crazy egg heads are doing to life and our amazing planet with their filthy magic.
What a load of crap
Make sure to pick up some leaches after your blood letting session.
Ugh, this is that same shit with far-left faggots who look and sound like sniveling worms.
Now that said, the far right is just as fucking stupid and blinkered. Isn't there any REAL documentaries on 3 mile island that arent self-serving political trash?
so whats the lodown 3 decades later? one reactor shut down and sealed up and are they still operating the others? I remember this even though I was very young and live close enough to limerick that when I see that place from a distance it brings an ominous feeling.. I am very interested in the subject and am amazed at nuclear power in general but I do think we wont see more facilities built from the issues of TMI Chernobyl and now Fukishima.
HEY! who cares what this guy has to say? seriously.. HO LETS JUST FORGET THE OPPOSITION! MAYBE THEY POINT OUT CRACKS IN OUR WALL BUT MAYBE WE CAN JUST BELIEVE THEM AWAY! oh ignorance…
Most likely.
Hola sera que me puedes enviar la descarga por favor. Saludos desde Venezuela!!
What a waste this video is. For goodness sake.
If three mile island exploded I would not be hear because my mom stayed at home with hear family hear dad said it is not going to explode she was in 1st grade
those 70s -80s hairstyles are just awful…
i was near there and had a metallic taste in my mouth which is linked to radioactivity in the air….but they hide all that
As a former Nuke in the US Submarine Navy, I'm here to tell you that nuclear power is the cleanest of the non-renewables, but it is highly dependent of operator training and proper operation. The US Navy has had only two lost nuclear power subs, and both were bc of failed aux systems, not the Rx itself. TMI, and Chernobyl were both bc of operator error. Fukushima was bc of poor planning, and subsequent violation of one Commandments of Nuclear Power operation: "Believe Your Indications"…if a gauge says 'X' , you go by that, you don't think the gauge is wrong. Chernobyl was intentional failure test performed outside of prescribed operating range. TMI was a disaster waiting to happen, from poor design to sloppy operation.
This video is in bad need of fact checking.

This needs fact checking. Besides most people don't actually know what "nuclear waste" is. It is actually an element called plutonium 239 which emits high amounts of alpha radiation. The misconception is that this radiation is dangerous. In fact this radiation can't even break the human layer of skin and is better known as ionized helium. Yes that stuff you inhale at parties. Plutonium 239 is dangerous however in two ways. One it is a carcinogen, so do not inhale. Two it is one of two key components in nuclear bombs. Knowing all of this, that stuff which is "waste" isn't waste at all. But rather a safe and energetic element that can be re-used in reactors when dealt with carefully instead of buried underground where it slowly turns into lead through alpha decay. If you don't believe me on the dangers of plutonium. Look at "QuantumBoffin" he is a youtube professor who does experiments with all forms of radiation and elements. Showing you are more at risk in your basement than at a reactor.
