Looks like a higher location is in order then. Can't see us abandoning the nuclear option whatever the present concerns. |

The reason the plant was near the sea was so that any tsunami that hit would only be water, not water plus bits of building, cars and other assorted debris. More modern designs have, in any case, done away with the need for pumped coolant and, hence, for the generators that were knocked out. Colin Bignell |

Not much of an excuse, given that there is evidence of a similar size tsunami there within the last 1000 years. It's all very well saying that it worked to its design criteria, but right now they aren't looking like the right design criteria.

There's a risk of complacent hubris, especially as this incident isn't over or even seemingly coming under control yet. |

Japan Nuclear Problem
We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "newshound" saying something like: But looking at the footage, when the No.3 building exploded, the fallout didn't appear to be going out to sea. Also, if it was a hydrogen explosion, why was the flame orange er, it is by the sea, and has just been innundated by a tsunami more than 6.5 metres high. So there is a bit of salt around.
