Tsunamis and nuclear power plants.

More than 300,000 people are dead. Bodies wash ashore in a dozen countries. A train, loaded with a thousand passengers and their luggage, is swept away, engine, tracks, and all. Cars, trucks, buses, and boats are pushed more than a mile inland by the rushing water. Some of the waves were reported to be 50 feet high.

The ocean in San Diego, half a world away, rose 10 inches. It is a small world, after all.

The "sea wall" at San Onofre Nuclear Generating Station (SONGS) in Southern California is 35 feet tall, and about 35 years old. It could not have withstood Sunday's worst.

San Onofre's twin reactors were theoretically designed to withstand an earthquake up to 7.0, which is 100 times smaller than a 9.0 earthquake.

Why did we build nuclear power plants near the ocean, anyway, where they are susceptible to underwater and surface attacks by terrorists and other belligerents? Because nuclear power plants need enormous quantities of water for their cooling systems, and water--especially in the western United States--is usually difficult to find except along the shoreline. The outflow from a nuclear power plant is always slightly contaminated with radioactive particles, and sometimes severely so; people don't want to drink that. So they put the plants near the oceans whenever possible.

Don't worry about tsunamis, they said--we've built you this puny little wall. Don't worry about asteroid impacts--they hardly ever happen. Don't worry about tornadoes or hurricanes. Don't worry about human error. So, society agreed to these poisonous cauldrons of bubbling radioactivity, these behemoths of death-rays ready to burst, these sitting ducks on our shorelines.

Don't worry, we were told, because the chances are very low. It's always about "chance" to the nuclear promoters, and never about "worst case scenarios." We're all playing the odds. Why? Clean energy, which has zero catastrophic risk, abounds; we just need to harness it.

These tsunami waves would have had little or no effect on floating offshore ocean wind energy farms (unless they were particularly close to shore), nor would they affect ocean thermal...
