Japan’s nuclear un-safety in 2004 – nothing has changed
Japan’s deadly game of nuclear roulette, Japan Times, BY LEUREN MORET MAY 23 2004 Of all the places in all the world where no one in their right mind would build scores of nuclear power plants, Japan would be pretty near the top of the list.
The Japanese archipelago is located on the so-called Pacific Rim of Fire, a large active volcanic and tectonic zone ringing North and South America, Asia and island arcs in Southeast Asia. The major earthquakes and active volcanoes occurring there are caused by the westward movement of the Pacific tectonic plate and other plates leading to subduction under Asia.
Japan sits on top of four tectonic plates, at the edge of the subduction zone, and is in one of the most tectonically active regions of the world. It was extreme pressures and temperatures, resulting from the violent plate movements beneath the seafloor, that created the beautiful islands and volcanoes of Japan.
Nonetheless, like many countries around the world — where General Electric and Westinghouse designs are used in 85 percent of all commercial reactors — Japan has turned to nuclear power as a major energy source.
In fact the three top nuclear-energy countries are the United States, where the existence of 118 reactors was acknowledged by the Department of Energy in 2000, France with 72 and Japan, where 52 active reactors were cited in a December 2003 Cabinet White Paper.
The 52 reactors in Japan — which generate a little over 30 percent of its electricity — are located in an area the size of California, many within 150 km of each other and almost all built along the coast where seawater is available to cool them.
However, many of those reactors have been negligently sited on active faults, particularly in the subduction zone along the Pacific coast, where major earthquakes of magnitude 7-8 or more on the Richter scale occur frequently. The periodicity of major earthquakes in Japan is less than 10 years. There is almost no geologic setting in the world more dangerous for nuclear power than Japan — the third-ranked country in the world for nuclear reactors.
“I think the situation right now is very scary,” says Katsuhiko Ishibashi, a seismologist and professor at Kobe University. “It’s like a kamikaze terrorist wrapped in bombs just waiting to explode.”……..
Yoichi Kikuchi, a Japanese nuclear engineer who also became a whistle-blower, has told me personally of many safety problems at Japan’s nuclear power plants, such as cracks in pipes in the cooling system from vibrations in the reactor. He said the electric companies are “gambling in a dangerous game to increase profits and decrease government oversight.”
Sugaoka agreed, saying, “The scariest thing, on top of all the other problems, is that all nuclear power plants are aging, causing a deterioration of piping and joints which are always exposed to strong radiation and heat.”
Like most whistle-blowers, Sugaoka and Kikuchi are citizen heroes, but are now unemployed…….
It is not a question of whether or not a nuclear disaster will occur in Japan; it is a question of when it will occur. http://www.japantimes.co.jp/life/2004/05/23/to-be-sorted/japans-deadly-game-of-nuclear-roulette/#.VMMMH9KUcnk
