It's unclear just how bad this is going to be, any nuclear accident is bad that's for sure. It's different than Chernobyl though. Chernobyl blew their reactor all over the countryside. This never happened in Japan, they blew up the top of the buildings, not the vessels. The reactor vessel is completely different, it didn't explode the fuel all over the countryside like Chernobyl. The fuel melt and vessel integrity needs to be examined first.
