Thats hard to do in Japan. Over there its common for mountain ranges to rise up within 10-15 miles of the shore line. I guess it comes down to a dliemma betweeen locating the nuclear reactors in the mountains (where they could be affected by earthquakes, landslides and volcanoes) or near the shore (where earthquakes, tsunamis and pacific hurricanes can affect them). Considering that Japan has very little coal, oil or natural gas they are sorta' locked into muclear power.
