Well the article certainly overstates the danger to the USA, however the danger to Tokyo and surrounding area is very real. Chernobyl released less then 200 tons of material we are looking at almost 500 tons here in a pool failure and more like over 1000 tons in a total uncontrolled meltdown/release of all 4 reactors.
Since I worked in the nuclear power industry, by no means am I underestimating the seriousness of developments at Fukushima. But radiation from Fukushima killing tens of thousands of Americans so far? No.
If the spent fuel rods are still in the spent fuel pool surrounded by water and the building’s walls, I cannot understand why the walls haven’t been sandbagged or in some other way provided with exterior support. The pool’s water and walls would provide shielding allowing outside work, unless there is so much radioactive material strewn about the site that this prevents work to shore up the pool’s walls - no one is willing to work a suicide mission. Still, robotic machines could shoreup the walls. It is worth a try rather than let the pool collapse.
Since I’m not there and don’t know the details this is only speculation on my part. Tiger likes Rooster might have more details.
