主题：日本福岛核电站传来爆炸声 -- 葡萄

即使最乐观的情况，ICU这关过了，美国媒体说，也要用海水持续降温数年，就象当年三里岛那样，堆芯彻底冷却，放射物半衰期已过，工作人员可以清理现场。

海水腐蚀性很强，希望安全壳别再泄漏了。那就真的用人填了。不过目前看起来怎么也比切尔诺贝利的情况好，毕竟有个乌龟壳罩着。苏联的核电站设计的太拙劣了，简直是裸奔。

What's the best-case scenario for either reactor?

Most likely, the company would keep pumping seawater through it for several years until it had cooled down sufficiently and many of the radioactive isotopes had decayed enough that engineers could go in and remove the fuel...

What's the worst-case scenario?

A breach in the containment vessel. If that happens, engineers would most likely have to entomb the reactor in concrete, as was done at Chernobyl, where a breach spread radioactive ash across most of Europe, except the Iberian peninsula.
