你们以为封堆就有用么！China Syndrome可是很坑爹的！（ ...

http://en.wikipedia.org/wiki/China_Syndrome

The China Syndrome is a fictional hypothetical idea of an extreme result of a nuclear meltdown in which molten reactor core products breach the barriers below them and flow downwards through the floor of the containment building. The origin of the phrase is the ficticious hyperbole that molten material from an American reactor could melt through the crust of the Earth and reach China.[1]

“中国综合症（暂译）”是一个虚构但理论上存在的概念：在极其严重的炉心融解事故中，熔化的燃料棒烧穿位于其下方的屏障，并进而向下穿透反应堆安全壳的底板。这一词语的来源基于一项夸张的假想：如果一个美国的反应堆里核燃料熔化，就有可能会烧穿地壳，并流到中国。

按照这项疯狂的假想，既然美国的核燃料可以流到中国，那么中国一衣带水的邻邦日本在这次核危机里，就算封堆成功，燃料棒仍然可能会从下方烧穿安全壳，然后通过“China Syindrome"流到美国去。。。。

The 'China Syndrome' refers to a catastrophic meltdown of a nuclear reactor. Also called a loss of coolant accident, the scenario begins when something causes the coolant level in a reactor vessel to drop, uncovering part—or all—of the fuel rod assemblies.
”中国综合症“指的是核电站中灾难性的炉心融解事故，又称作冷却剂失效事故。当某种因素造成反应堆容器里冷却剂水位下降并使得燃料棒部分--或是整体完全暴露时，这种情况就会出现。
For a complete meltdown to occur, all control rods must be uncovered by cooling media; otherwise, only a partial meltdown is possible and any melting will form in pellets under the water remaining in the reactor.
若出现核心完全熔解的事故，那么所有的控制棒都已经得不到冷却剂的覆盖。如果仅仅是部分熔解，那么熔解掉的部分将会掉入反应堆里残留的水中并形成颗粒状沉积物。
Even if the nuclear chain reaction has been stopped through use of control rods or other devices, the fuel continues to produce significant residual heat for some time. If not properly cooled, the fuel assemblies will soften and melt, falling to the bottom of the reactor vessel.
就算反应堆里的链式反应通过控制棒或者其他设备得到停止，核燃料仍然会在一段时间内继续产生巨量的残余热量。如果得不到适当的冷却，燃料棒将会软化并熔解，掉落到反应堆容器的底部。
If cooling media is present, disks or pellets will form and not a solid molten mass. There, without neutron-absorbing control rods to prevent it, nuclear fission could resume but, in the presence of a neutron moderator, might not.
如果还有残留的冷却剂，那么从熔解的燃料棒上下落的物质会凝结成颗粒状沉积物，但不会形成一块固态整体。在反应堆的底层，因为没有能吸收中子的控制棒，核裂变仍然会继续，但在有中子吸收剂的情况下便不一定会进行。
Regardless, the temperature of the molten fuel during a full meltdown resting on the steel floor of the reactor hypothetically would increase to the point where it melts through the container and enters a 5-6 foot steel floor underneath.
无视这一切的是，在核心完全溶解的事故中，熔化的核燃料在反应堆容器底部不断积累，理论上会达到烧穿容器的程度，并渗入下方钢制底板达5--6英尺。
Many feet of reinforced concrete under the steel floor would then need to be breached. Although many feel the radioactive slag would stop at the steel level or concrete level, hypothetical breaches to the subterranean aquifer have been postulated; such a series of events would release indefinite amounts of radioactive material into the atmosphere and groundwater and hypothetically cause widespread damage to the environment and plant and animal life.[5]
在钢制底板下方数英尺厚的钢筋混凝土也将会被击穿。尽管很多人认为放射性沉积物将会在钢制底板或混凝土底板处停止流动，但理论上说，所有的屏蔽物统统被烧穿，放射性物质进入到地下含水层的可能性也是存在的。这样一连串的事故将会将无可估量的放射性物质泄漏到大气层和地下水层中，并将理论上对环境和动植物生命造成极大规模的破坏。

Nuclear power plants ordered during the late 1960s raised safety questions and created fears that a severe reactor accident could release large quantities of radioactive material into the environment. In the early 1970s, a controversy arose regarding the ability of emergency cooling systems to prevent a core meltdown, which might lead to the so-called China Syndrome. This issue was discussed in the popular media and technical journals.[2]
1960年代后期大量的新核电站建造计划激发了一系列对安全问题的思考，也造成了恐慌，担心严重的核事故将会使巨量的放射性物质逃逸到自然环境中。70年代早期，出现了有关核电站紧急制冷系统是否有能力阻止炉心融解事故的发生的争议，而炉心融解将会引发所谓的“中国综合症”。这一问题在大众媒体和学术期刊上得到了广泛讨论。
In 1971, nuclear physicist Ralph Lapp used the term "China syndrome" to describe a possible burn-through, following a loss of coolant accident of the reactor containment structures and the subsequent escape of radioactive material into the environment. His statements were based on the report of a task force of nuclear physicists headed by Dr. W.K. Ergen, published in 1967.[3] The dangers of such a hypothetical accident were popularized by the 1979 film, The China Syndrome.
The name itself comes from the idea that, to many Americans, "the other side of the world" is China.[4]
1971年，和物理学家Ralph Lapp首次使用了“中国综合症”一词来形容因反应堆冷却剂失效而造成炉心融解进而烧穿反应堆安全壳并造成放射性物质逃逸这样的事故。他的学说基于一支由物理学家W.K Ergen带领的特别研究小组所做的报告，该报告与1967年公布。
这样一个理论上存在的事故的危险性因一部1979年的电影“中国综合症”而为大众所熟知。之所以叫做“中国综合症”是因为不少在美国人的意识中，地球的另一侧正是中国。
