Hyping Japan's Nuclear Dangers?

'Let us be clear. Compared to the real disaster at hand, the hypothetical threat from the nuclear stations is zero. The reactors in question were all shut down four days ago. The control rods have been inserted, and the cores have been salted with boron. It is physically impossible for them to sustain a fission reaction of any kind at this point, let alone cause another Chernobyl. Only the fission-byproduct decay heat remains, and it is fading fast as the short half-life material (which accounts for most of the radioactivity) performs its decay reactions and ceases to exist. At this point, the total heating power in the reactors is only about 0.3 percent of what it was when the reactors were operating. That means that a system previously capable of generating 1,300 megawatts of heat would now yield 4 megawatts thermal -- about the same as that emitted by a dozen 100-horsepower automobile engines. The Japanese engineers can certainly deal with that with water cooling. And even if they were to stop, there just isnâ??t enough heating power in the system anymore to generate a dangerous plume of radioactive materials, which is doubly impossible at this point since all the more active short half-life stuff is already gone.'
