Former Ambassador: No. 4 reactor a top national security issue for entire world — Could start “the ultimate catastrophe”


"[...] Mitsuhei Murata, 74, a professor emeritus at Tokaigakuen University who once served as Japan’s ambassador to Switzerland, said, “The existence of the No. 4 reactor has become a major national security issue for the entire world that does not take a back seat even to North Korea’s missile issue.” He had called for a halt to operations at the Hamaoka nuclear power plant even before the Great East Japan Earthquake struck last year, leading to the nuclear crisis. “If an accident should occur at the No. 4 reactor, it could be called the start of the ultimate catastrophe for the world,” Murata said as a witness at an Upper House Budget Committee hearing in March. [...]"

Large amounts of radioactive materials could be deposited across 1,000s of miles if water lost at Fukushima fuel pool — Media just beginning to grasp that danger to world is far from over -Nuclear Expert

Nearly all of the 10,893 spent fuel assemblies sit in pools vulnerable to future earthquakes, with roughly 85 times more long-lived radioactivity than released at Chernobyl • Several pools are 100 feet above the ground and are completely open to the atmosphere because the reactor buildings were demolished by explosions. The pools could possibly topple or collapse from structural damage coupled with another powerful earthquake.
• The loss of water exposing the spent fuel will result in overheating and can cause melting and ignite its zirconium metal cladding resulting in a fire that could deposit large amounts of radioactive materials over hundreds, if not thousands of miles. [...]

Sounds dreadfully unpleasant (Think of a British accent while reading that, I'm trying to learn their understated ways of expressing themselves).

Can somebody create a map of where all that stuff is going to go? I assume most will follow the prevailing winds and currents across the Pacific to the west coast of the US...ruh-roh is right.
 
I agree. It is a big problem. Bigger though is the threat of an EMP over the US or major sun activity that can fry our grid. How many nuke plants do we have that will melt in that situation? I don't want to think of the consequences.
 
Nothing to see here... they are just trying to milk the last of this Fukushima "catastrophe"

It was a freak occurrence with a large earthquake (which the plants survived) and a beyond design basis tsunami

With a dispersion model, you can calculate how far the radionuclides will travel from Japan and it will be lower than background radiation by the time it reaches say North America

so again... nothing to see here
