US: Nothing To Stop Japan Nuke Meltdown
Is a total meltdown inevitable
The chief of the U.S. Nuclear Regulatory Commission said Wednesday that all the water is gone from one of the spent fuel pools at Japan’s most troubled nuclear plant, but Japanese officials denied it.
If NRC Chairman Gregory Jaczko is correct, this would mean there’s nothing to stop the fuel rods from getting hotter and ultimately melting down. The outer shell of the rods could also ignite with enough force to propel the radioactive fuel inside over a wide area. Jaczko did not say Wednesday how the information was obtained, but the NRC and U.S. Department of Energy both have experts on site at the Fukushima Dai-ichi complex of six reactors. He said the spent fuel pool of the complex’s Unit 4 reactor has lost water.
Jaczko said officials believe radiation levels are extremely high, and that could affect workers’ ability to stop temperatures from escalating.
Japan’s nuclear safety agency and Tokyo Electric Power Co., which operates the complex, deny water is gone from the pool. Utility spokesman Hajime Motojuku said the “condition is stable” at Unit 4.” source – NPR

Japanese researchers have invented a speech-jamming gadget that painlessly forces people into silence. Kazutaka Kurihara of the National Institute of Advanced Industrial Science and Technology, and Koji Tsukada of Ochanomizu University, developed a portable “SpeechJammer” gun that can silence people more than 30 meters away.

“During both the first and second round of discussions, the agency team requested access to the military site at Parchin. Iran did not grant permission for this visit to take place,” the Vienna-based IAEA said in a statement after the talks Monday and Tuesday talks in the Iranian capital. “We do not wait for enemies to take action against us,” said Iran, according to the semiofficial Fars news agency. “We will use all our means to protect our national interests.”

A report that Iran is about a year away from having the capability to build a nuclear bomb may be too optimistic, contended John Bolton, former U.S. ambassador to the United Nations. “I worry the publicly available information is giving only a very small picture and that Iran is actually even much further along,” Bolton said today in a radio interview.
