As far as I know, the design of the reactor itself is not at fault. The

It is a story
Any reactor larger than ca. 400 MWe needs active cooling system, because power
output is larger that can be cooled down passively. However, 300 MWe and less
can be cooled down after the shut down just submerging reactor into water,
hence they are inherently safe. And there won't be reactor
In engineering, the simplest design is usually the most elegant, prudent,
safest, and cost effective design.
The Light Water reactor design is a Rube Goldberg Machine design which
leads to high cost and over complication.

Yes. Right. We got it. However there are none available at present.
Right? So why blame this particular design? Any currently available

A good nuclear reactor design should be air cooled. Such as design can be
upscaled to handle any cool down heat capacity.

You really think people know what they want? The vast majority of people don't
think cold fusion is possible, and an even larger amount don't care and focus
on issues that don't matter. Most people reject cold fusion, so we should
invest no money into it because it would be a waste of money?

one thing missing were sand filters, that are installed in french

Sure. There are several designs that use passive cooling. The pebble bed
reactor is another example. But none have been commercialized yet. The
designs are
FYI:
The EPR is equipped with what Areva refers to as a “core catcher.” If the
fuel cladding and reactor vessel systems and associated piping become
molten, these first two safety mechanisms the molten core will fall into a
core catcher which holds the molten material and has the ability to cool

Hi,

I think the problem can be addressed by putting emergency generators far
above the waterline, perhaps in the second story of the reactor building.
I suggest building the entire reactor on the sea floor off shore.
Both underwater and underground deployment of nuclear plants is ideal for
certain types of nuclear designs that are totally passively controlled.
This design is old and venerable. Being greatly concerned about nuclear
safety, the last paper that Dr. Edward Teller (designed the H bomb) wrote
Japanese experts warn of earthquakes that could produce 34-metre tsunamis
http://www.guardian.co.uk/world/2012/apr/01/japan-earthquake-tsunami-wave-risk
Much of Japan's Pacific coast would be inundated by a tsunami more than 34
metres (112 feet) high if an offshore earthquake as powerful as last
be some material that
can be flooded into the reactor vessel that would behave in this manner, at
least I hope there is.

After a reactor shuts down, 15% of the rated capacity of the reactor is
released as delayed heat due to the decay of short lived radioactive
byproducts. This delayed heat must be dissipated into the environment to
