With all the media hoopla surrounding the nuclear incident in Japan after the earthquake, the media, as expected, bungled on a lot of accuracy regarding the physics and engineering of such a thing. And the use of talking heads (Michio Kaku, really?) to discuss what essentially required a nuclear engineer to elaborate is beyond comprehension.
So it is nice to find an article like this, written by a nuclear engineer. It also reflected what I had gathered from the news article about the incident. The FACT here is that all these reactors SURVIVED the devastating earthquakes! Let's not for this important point. The structural integrity was maintained at all the nuclear reactors. What happened subsequently is the inability to maintain power to the pumps to continue the cooling process in the core, due to the flooding.
There's a tremendous amount of lessons that the nuclear industry can learn from this, and this can only make these things even safer. But the public also need to pay attention to the details and where nuclear industries got it right! For once, don't be swayed by the bells and whistles, but really, really look at the facts as they are!
