thread_title:  Origin 

message: I was watching the parrot channel yesterday and they said that china syndrome was not the reactor melting, but the result, which is molten hot nuclear material burrowing into the earth and causing radioactive steam to shoot up out of the surrounding area. I attempted to find a website that mentioned this with no luck. I found several sites that mentioned. In my searches though I did find china syndrome as a common phrase that seemed to mean, "bad thing". For example these articles  . I'm not certain enough to change the disambig page without seeing the show again but I'd really appreciate some source for the current claim. Vicarious 12:58, 3 March 2006 (UTC)

message: I've removed the following content which was recently added by an anonymous user: "The phrase arouse from the material corium produced in a meltdown: a mix of uranium oxide, aluminium, steel and other metals and metallic oxides which resembles china (the material)."
If someone can find a source I'll recant but this doesn't make sense to me. China is a type of porcelain, the photos I can find of corium  don't look anything like porcelain. At best corium looks like the crude slag of china, but certainly not comparable enough to be named such. Vicarious 06:10, 27 November 2006 (UTC)

message: I have twice reverted a change of the last sentence in the article to the following:
:Fortunately, no evidence of this occurring has yet been observed. Although there have been several meltdowns of both civilian and military reactors none have resulted in a "China Syndrome" fictionalized or otherwise.
The anonymous editor (129.174.177.126) who made these changes states that 'your version [current] is clearly biased, mine is clearly objective'.  I do not see any overt bias in either one, but I have serious problems with their version.  What does 'no evidence of this occurring has yet been observed' mean?  If a reactor were to melt down in this fashion, it would be rather blatantly obvious to anyone within a very large radius.  It is possible that the editor contests the possibility of such a meltdown happening.  In that case, I ask the editor to remember physics: if the reactor gets too hot, it will weaken the containment container and the bottom will break.  Fortunately, the most common reactor designs are self-limiting, but some are not.  With respect to the last clause, 'none have resulted in a China Syndrome fictionalized or otherwise': if a real reactor melts down, it can't produce a fictionalized China Syndrome.

This is not a question about the neutrality of the article (note that the two versions say exactly the same thing, merely in different words).  It is simply a matter of clarity and grammar.

message: Bottom line: a longstand meme in the USA is "digging a hole to China", imagining that China was directly opposite the States.  Beyond this, it refers the supposed difficulties of comprehending a Spherical Earth -- "So, people in China are walking upside-down!?" -- and it went from there.  Beyond that, "China Syndrome" sounds exotic and scary (Ironically, despite the "leftism" of many of the major actors in this movie, "China Syndrome" certainly has a hint of racism to it -- but I digress.).  Again, bottom line, its from the meme of a Spherical (Spheroid, I suppose) Earth, and a yokel's (or child's) concept that one could thus "dig a hole to China" (where people walk upside-down, and hamburgers eat people.) :D  —Preceding unsigned comment added by 71.235.56.24 (talk) 13:58, 25 April 2011 (UTC)
replies: text: The idea is that the reactor would melt through the ground, through the core of the earth, and eventually emerge on the other side of the world. China is regarded as "the other side of the world" to most Americans, although I do not know if this is technically true. I do not believe that it is possible for a reactor to melt its way to the core of the earth. And of course, if this were possible, gravity would prevent it from emerging on the other side. --70.81.251.32 13:20, 8 May 2007 (UTC)
replies: text:  Furthermore, the article states:  The impossibility of the material actually reaching China is due to the fact that the molten fissile material would have to go both with gravity and then against gravity and a line drawn from the United States through the center of the Earth would emerge in the south Indian Ocean and not China.

replies: text: Many years (perhaps decades) ago, it used to be said (jokingly, usually to children), that if you dig a hole in the ground and keep digging deep enough, you'll end up in China.

text: The antipodes for the "lower 48" United States lie west of Australia, in the Indian Ocean. The extremely northern part of Montana does lie opposite to the French Southern & Antarctic Lands, however, and there are probably small inhabited islands in that region. China is opposite only to Argentina and Chile, interestingly. Alaska lands far south of Africa, just bordering on Antarctica; Hawaii is in Botswana and Namibia. Most realistically, this could only be called a Botswana Syndrome. 65.96.201.130 (talk) 16:51, 13 February 2009 (UTC)

text: Unfortunately the term China Syndrome is completely misleading. If it is intended to imply that molten material could reach the other side of the earth, the concept is so ridiciulous as to be off the planet. If it is intended to imply the possible breach of containment, then that is a legitimate theory - but needs a new name.  —Preceding unsigned comment added by 124.197.15.138 (talk) 19:26, 12 March 2011 (UTC)

thread_title:  Why "China" 

message: "Despite several meltdowns in both civilian and military reactors, such an extreme meltdown has never taken place.[citation needed]"
Why is this marked as "citation needed"? How do you prove that something has not happened? --J-Star (talk) 15:31, 22 May 2008 (UTC)
replies: text: Yes, actually there is doubt. Uranium has poor water soluability to begin with, and the same goes for most of the dangerous fallout products. Second we don't know anything about the thermodynamics what takes place when the molten magma reaches the water table... if the water will cool it enough to form a protectve crust or what exactly happens. So yes, there is definatly "citation needed" here. --J-Star (talk) 06:51, 3 October 2008 (UTC)

thread_title:  etymology 

message: Responding to the Wiki China Syndrome article and the comments below, and looking up Wiki article on the "Earth's inner core" I note the comment that "the Inner core may be hotter than the sun's surface".  Taking that into consideration, gravity and where China is at any given point is the least of our worries!!  I don't mean to cause a panic, but if it is possible for reactor material to reach the core of the earth, we're all in BIG trouble!!

The idea is that the reactor would melt through the ground, through the core of the earth, and eventually emerge on the other side of the world.

The mantle is not liquid (not even the asthenosphere), it is solid-plastic. This sentence should be changed to be,"...kept hot by natural nuclear decay."  — Preceding unsigned comment added by Kgressett (talk • contribs) 02:05, 12 March 2011 (UTC)

message: I'm not too thrilled with the second sentence of this article which states "The origin of the phrase is the fact that molten material from an American reactor..." Later in the article, this sentence appears: "The China syndrome becomes fictional in the hypothesis of it boring a hole from the United States to China..." The article itself makes it clear to a reader that it is not a 'fact' that a core could melt through the core to China, and the first paragraph should reflect this. Fact should be changed to "Conjecture", or something that does not imply truth. Cythro (talk) 15:38, 13 March 2011 (UTC)

thread_title:  Editing 

message: Some comments on the anonymous, uncited edits I'm reverting: 
1) It's made pretty clear by the lede that the scenario is hypothetical. We don't need to add "fictional" and "fictitious" to a bunch of subsequent sentences.
2) Fuel melting may occur when part, or all, of the fuel produces more heat than is being removed--this is simple physics. Whether or not the control rods are uncovered is irrelevant. In fact, in many reactor designs, the coolant is also the moderator, loss of which will stop the fission reaction.
3) There is no such thing as a "solid molten mass". 
4) If the molten material stops within the containment vessel or building, is is not a "China syndrome" event, and thus outside of the scope of this article. You may reference the WP article on "meltdown" but this one is not such.
5) Please don't add empty sections ("== Scientific explanation of why this is not possible ==").
Let's remember, please, that this entire article is about a sort-of-silly figure of speech coined years ago by a reporter. Let's not let it grow out of proportion to its purpose.

thread_title:  Attempts to remove hyperbole, weasel-words and POV 

message: Looks to me like the headings 'scientific explanation' and 'scientific explanation of why this is not possible' were added by someone who thought there should be such an explanation rather than someone able to give one. I removed the second heading which had no text and retitled the first to make it more neutral. In general sections that have to describe themselves as scientific are probably not. The section itself is a mess, lots of unsourced heresay.
The real point being made in the term is rhetorical. Once the reactor vessel is breached, there is nothing to stop a catastrophe. It is a question of what the catastrophe will be, not whether. If the reactor did actually melt down it would probably burn a hole in the bottom of the vessel and then the pressurized steam built up would explode out the bottom sending the containment vessel upwards like a rocket. --  —Preceding unsigned comment added by 98.216.39.121 (talk) 15:42, 15 March 2011 (UTC)
replies: text: I agree with your assertions regarding the article's headings--and your subsequent edits--but I gotta point out that, considering the pressure-to-weight ratio of the structures involved, the containment vessel would not shoot upward "like a rocket". Aside from that, though, you're spot-on! Thanks! — UncleBubba ( T @ C ) 00:35, 17 March 2011 (UTC)
thread_title:  Not very scientific 

message: The section of the article pertaining to the hydrogen explosions at this site by no means hold any relevance to "china syndrom".
It is simply hyperbole that is disingenous at best. I am deleting this section; as this kind of topic does not need a "concern" section relating to every nuclear reactor. In short: there is no evidence of any nuclear explosion or meltdown at Fukushima and thus no grounds for "concern" relating to a hypothetical analogy from the 1970s.
Also, it appears the 3-Mile Island "was not" section was created days ago in some kind of attempt to legitimise the creation of 'Fukushima'. I feel slightly compelled to omit this irrelevance too; but as it is a historically documented (actual) nuclear incident, and the time of that event; I believe is hold just enough relevance. 119.161.71.12 (talk) 09:15, 18 March 2011 (UTC)
thread_title:  Fukushima 

message: Wow, this thing seems to creep out of it's topic box faster than kudzu growing during an Atlanta summer. I've been editing here with the understanding that the article is about the (fanciful, fictional, made-up; pick one) term (see above) and nothing more. It's especially not a catch-all for all things radioactive, hot and/or gooey. 
So, here's the question: It ain't my article and I certainly don't want to go against consensus but, on the other hand, I feel really strongly that this article should remain short and factual--especially now, considering current events.
What do y'all think? Let's discuss it. (But let's stay calm--that's really the only way to get things done here.) 
Thanks! — UncleBubba ( T @ C ) 17:47, 24 March 2011 (UTC)
replies: text: My thoughts exactly. The article should really about the idiom and little more. Using the term "China syndrome" is a very bad start to a scientific conversation so it shouldn't be the subject of a long scientific article. I'd go as far as suggesting that we clean up the incoming links accordingly. Pichpich (talk) 21:26, 24 March 2011 (UTC)
thread_title:  It Seems to be Happening Again... 

message: I thought this phenomenon was called the China Syndrome because the nuclear core could possibly burn right through the earth through the planet to the other side, not 
because it could just break it's containment vessel, isn't that what it means? Not that it could happen, but isn't that where the term comes from? And, I wonder if it could why they cover the core with sand, concrete, why not launch into space/the sun?  —Preceding unsigned comment added by 66.189.38.183 (talk) 10:01, 7 May 2011 (UTC)
