Not really, because the majority of nuclear plants are as old as the one in Japan. Nuclear Power is extremely safe, mainly because of the fact it is the most heavily regulated industry on the planet and we really go nuts with safety and for good reason, had we not, we would have 130,000 irradiated Japanese people running around Japan right now. A lot of people's concerns with nuclear power are born out of ignorance and misinformation. It makes me very reluctant to enter a debate or discussion when people says things like "Nuclear reactors could explode [a la warheads]!" (Not that people here say that, but I've become jaded)
