Let's not be racist about it. The plant was designed by General Electric (GE nowadays). Immelt, slimy toad that he is, jumped in the media fray VERY early on, to do damage control:

He offered help! He should have started by offering excuses! A group of GE whistleblowers were pointing out design flaws in that exact type of plant in the 970s! Design flaws which played a role in the accident, moreover:

You do know, Google senpai, that there are several methods, none of which have been validated in proper epidemiological studies?

The Techa river cohort is just about all we had, pre-Fukushima.

Now, there will be the Fukushima schoolchildren to study. Their deaths from cancer and leukemia will further enlighten us, 50 years from now....

I like to believe that I am on a tech-oriented site where being right is more important than being polite.

There is no downmod for "stuff that I happen to find offensive" by the way but feel free to abuse mod points and call me a troll, if you have them.

Or if you don't like my style you could say it to my face, using your own name to identify yourself like a real person does.

Unit 1 IC train A was shut down by operators to avoid excessive cooling which would have thermally stressed the metal of the RPV and shortened the life of an already old plant. Later, power to operate the valves that would have made it active again became unavailable.

At that point, the RPV should have been vented and water should have been added using fire engines. This was not done for a variety of reasons, such as that the evacuation was not over yet. When at last venting was attempted, it was found that a valve needed for venting ad failed closed, possibly because of excessive pressure. Attempts to open it manually met with failure.

So, eventually the reactor vented itself. Explosively.

The severe accident management guidelines did NOT, in fact, state that venting should only be performed post-evac. They were ignored in the event.

Even later in the accident sequence sufficient fresh water became unavailable for a while (the first reactor explosion damaged fire trucks, severed water lines and prompted a TOTAL evacuation of the site). A decision was made to delay salt-water cooling. This probably contributed to the melt-through in reactor 3.
