The fact is, those design changes did not happen, and not because they were not thought of. Rather, management rejected adding them in each case, in detail.

Fixing faulty engineering processes has been demonstrated. Management, not so much. We have sound reasons to believe no systematic management improvements would be evident in future nuke projects.

Regarding venting the overpressure hydrogen gas outside instead of inside - was that rejected in detail?

Besides, my experience is that engineers do not think of these things until after the fact. Have you noticed them in any academic book on engineering? I've never noticed them in any, nor in any software engineering book.

Venting hydrogen is a thing after you already have a meltdown. It is already too late to forestall disaster. You already have one.

What was rejected include an adequate seawall, and backup generators where a tsunami would not flood them. We know the ideas were rejected, because at a sister site only a few miles up the coast, rejections were overcome.
