How many people died in Three Mile Island? Zero.
As to the New Madrid fault, that's just fear-mongering from the media. Realize, Fukushima was a 40-year-old plant located right on the coastline of the Ring of Fire where 90% of the world's earthquakes occur. It withstood the shaking from the largest recorded quake in Japan's history. It was the 45-foot tsunami that knocked it down.
The tsunami killed 25,000 people.
