Nuclear is heavily regulated and very closely kept under surveillance, so you could say it should be safer than many other industrial plants. But it needs massive investments (big money tends to blur and hide things) and the subject is highly political too. Your best bet is that the transparency isn't up to the claim and actually most of us never really know what's going on. We just can hope that this engineering marvel is created by and entrusted to the top notch people / companies existing.
