灾难来临：美国爆料日本福岛核电站已融堆

　　据美媒说，日本福岛核电站原来分隔的核燃料，完全融成一堆了，这就再也无法控制了。

　　阻止核反应进行的方法，主要是加含硼的物质，融堆之后，硼酸就加不进去了。

　　因为核燃料的比重很大，比较轻的硼酸只会浮在表面。进不了堆芯中，因此也就没办法停止核反应了。

　　核反应的温度是没有上限的，他不像烧煤，有一个最高温度，他可以无限升温的。

　　因此这一大团极高温度的核燃料，将会慢慢下沉，熔穿地基后沉入地壳中去。

　　真的沉下去倒也罢了，问题是沉的速度极慢，而且一路上副反应很多。

　　1986年核事故后的切尔诺贝利核电站。烟囱前是被毁的第四核反应堆。

　　当年苏联切尔诺贝利事故时。苏联工程人员不顾死亡的威胁，从反应堆的边上打了一条地道，在反应堆的下方铺设了一个阻止反应的地板。

　　核燃料遇上这块地板就会停止反应。这是正确的办法。

　　话说当年苏联救援的军人的确是勇敢无畏。

　　直升机驾驶员知道自已会死，但是还是义无反顾地驾驶着直升机向反应堆投硼砂和水泥。

　　大祸临头：日本核电站突喷核蒸汽 美国遭殃

　　Unexplained plumes ofradioactive steam have been rising from Fukushima‘s Reactor Building 3. TEPCOhas confirmed the reports， adding that they were not clear on the details ofthe sudden change at the reactor because of “lethal radiation levels inthat building.” Meanwhile some experts think that “the situationcould escalate rapidly out of control.”

　　（日本）福岛核电站3号堆突然喷出未知核蒸汽。东电已确认了此事，但表示他们也不清楚到底发生了什么，因为“建筑内的辐射程度已经达到了致死标准”。一些专家们认为，福岛的情况“可能会迅速恶化，失去控制”。

　　Unexplained plumes ofradioactive steam have been rising from Fukushima’s Reactor Building 3. TEPCOhas confirmed the reports， adding that they were not clear on the details ofthe sudden change at the reactor because of “lethal radiation levels inthat building.”

　　Fukushima‘s Reactor Building3 exploded on 13th March 2011 as a result of a hydrogen buildup， breaching thebuilding’s containment and emitting a huge plume of radiation. The reactoritself is in meltdown.

　　福岛核电站3号堆突然喷出未知核蒸汽。东电已确认了此事，但表示他们也不清楚到底发生了什么，因为“建筑内的辐射程度已经达到了致死标准”。

　　福岛3号堆在2011年3月13日就曾爆炸过一次，当时从建筑的烟道管内喷出了巨量的辐射烟气。核电站本身则在聚变中被烧熔了。

　　And now fresh plumesof steam have been seen coming out the structure. These have now been confirmedby TEPCO， the owner of the nuclear plant， from 19th December onwards. Thecompany believes the steam is coming from the fifth floor of the building.

　　现在这个反应堆又开始往外喷蒸汽了。核电站的所有者东电已确认了此事。东电公司认为，蒸汽应该是从建筑的第五楼冒出的。

　　However it does notknow the cause of the steam. Lethal levels of radiation and the physical damageto the structure have so far made entry and inspection impossible.

　　Summations fromexperts conclude that this may “be the beginning of a ‘spent fuel poolcriticality （meltdown）’ involving up to 89 tons of nuclear fuel burning up intothe atmosphere and heading to North America.”

　　不过，蒸汽的成因却是无人知晓。由于核辐射程度已经达到了致人死命的水准，建筑结构也被严重破坏，进入核电站进行查看已经是不可能的事。

　　一些专家们认为，这是“废燃料池已达到融化的临界值”的征兆，一旦大祸酿成，89吨核燃料所化成的蒸汽将被喷到大气中，并飘向北美。

　　Educated guessessuggest that the steam is “coming from what’s left of the fifth floor ofthe mostly-destroyed building.”

　　TEPCO has admittedthat “they do not know why this steam is being generated， butmatter-of-factly revealed today （December 28） the steam was first spotted onDecember 19 for a short period of time， then again on December 24 and again onDecember 25.”

　　一些人根据这些迹象猜测，蒸汽来自“残破不堪的建筑的五楼”。

　　东电则坦承了此事，并表示“他们也不知道蒸汽是怎样产生的”“实际上，蒸汽在12月19日（2013年）就冒过一阵子，后来在24日和25日又各喷了一次。”

　　The accord is that“pellets of radioactive fuel， ejected when the reactor exploded， went intothe spent fuel pool located above the reactor and have begun melting down soseriously they are boiling off the water in the spent fuel pool.”

　　目前的一种解释是：“在反应堆爆炸时，核燃料的碎块四散开来，打进了反应堆上方的废燃料池里，随后开始剧烈的溶解，热量将池内的水变成了蒸汽。”

　　Should this be thecase “the situation could escalate rapidly out of control.”

　　TRN is warning ofpreparatory measures that should be taken by those living on the West Coast ofAmerica because after the “releasing 89 tons of deadly radioactive fueldirectly into the air”， it would be a matter or 2 to 3 days before thedeadly material would fry North America “by ［the］ levels of airborneradiation and ‘hot particles’ which could kill.”

　　现在的形势“可能会迅速恶化，失去控制”。

　　TRN警告美国西海岸一带的居民，一旦这“89吨辐射剂量致死的核燃料被直接排放进大气里”，就要采取必要的初步措施，因为废气很有可能会在2到3天内就抵达北美。
