Greenpeace has a cool new tool that enables residents of the US (and Canada) to visualize just how close we live to a possible meltdown. Just plug in your location or zip code and up pops a map showing the distance to the nearest plant and the area that regulators have designated as an "emergency planning" zone in case of accident. Click further on "details" and you can read how many people operators project an accident might kill. Really.
Looking at the map of the whole country (above) it is noticeable that most plants are in the east, the southeast and midwest. The far west has so far been relatively abstemious about building these accidents waiting to happen. Considering that the left coast is honey-combed with known earthquake faults, that's sane of us.
