Safety
Note how the specifications of 1 in 10,000 years or 1 in 100,000 years etc. are for a single reactor core.

Spoiler for Personal opinion/rant :|:

Such statistics, even 1 in 10,000,000 don't look so impossible after being stretched over the lifetime and number of plants out there. Toss in human error, incompetence, corporate overhead, and natural disasters...there is no design that prevents failure 100% of the time.

Management never thinks they'll be the ones who have to clean the mess up. Many can't seem to grasp the concept that the worst is given a number, because it can happen - you can't just hand-wave it off. The case of "when it doesn't work" has to be thoroughly addressed, and that seems like something the nuclear industry does not want to do (perhaps, because there is nothing to tip the benefit scale against cleanup costs).

TEPCO is not to say, Areva, as BP is to its competitors. And more importantly, there is no such thing as a relief well for the site. It seems as though the plan is that there is no plan. Or there is a plan, but it involves just dumping everything into the ocean, and the public shouldn't hear of it...

Guess nobody thought it could happen...
