Wingnuts want to build a lot more nuclear reactors. I got no problem with that. They need to be shielded and able to shut down in such a manner that they can withstand at least 9 Richter scale earthquakes and tsunamis like happened in Japan last week.
The San Onofre plant is about 20 miles from my house. It's already operated ten years past its designed shutdown date. The reason is because there is no way they can shut it down and stabilize the site in a safe manner. I'm pretty sure that any kind of major seismic event in the area, much less a monster tidal wave would totally fuck up a big chunk of the SoCal coast, radioactivity wise. I doubt it would do the Pacific Ocean that much good either.
