The China Syndrome

Reading the news about the potential nuclear catastrophe now looming in Japan reminded me of the following scene from the movie The China Syndrome. In this scene, starting around 2 minutes in, a scientist explains just what "The China Syndrome" is. Obviously I'm no expert, but I assume this is precisely what they are currently desperately trying to prevent from happening in Japan. Keep in mind this is only a movie so the actor's statement about the size of the impact from a nuclear plant meltdown may be an exaggeration.
