Exactly. The current designs are much safer. Not only that, but the realistic dangers from meltdown are tiny in the scheme of things. Even assuming a terrible terrorist attack, causing the reactor to meltdown and spew radioactive scariness all over a ten-mile radius. It'd be bad, sure, and many would no doubt lose their lives, but it'd be an isolated incident. Letting coal plants continue to burn for false fears of atomic death would lead to thousands more deaths every year due to lung disease from air pollution, especially in places like China where the population is exploding.
