The Jap nuclear reactor problem forms a nice neat litmus test of sanity for other rich countries.
Sane France has made it clear that it will proceed with nuclear. France has already planned smaller less centralized reactors, some of which will be under the ocean. That's an ideal fail-safe design. If everything blows and breaks, the ocean will cool down and shield the reaction. Good old water is one of the best shields.
Sane China has made it clear that it will proceed with nuclear. New Chinese reactor designs don't rely on diesel-powered emergency cooling; they simply have a huge water tank above the reactor, so that gravity can send the water in. Another smart fail-safe device.
Insane America is going to "put on the brakes" (so says lunatic imbecile Lieberman) which is a bizarre phrase since we've had the brake lever fully jammed and rusted for 30 years. We were just recently starting to ask whether we might think about backing it off a notch or two. In the most decerebrate parts of this unfortunate land, the Gaian superstition about Taboo Materials has led some vaguely humanoid units to hoard potassium iodide pills.
