With fears of a possible nuclear meltdown(核反应堆堆芯的熔毁) in Japan building up, evidence has come to light that the nation received warnings over the stability of its power plants from an international watchdog more than two years ago.
　　As the Telegraph is reporting, an official from the International Atomic Energy Agency (IAEA) said in December 2008 that safety rules were out of date, and strong earthquakes would cause a “serious problem” for the power stations.
　　A U.S. embassy document, by quoting（引用）an unnamed expert, states: “He (the IAEA official) explained that safety guides for earthquakes have only been updated three times in the last 35 years and that the IAEA is now re-examining them. Also, the presenter noted recent earthquakes in some cases have gone beyond the design basis for some nuclear plants, and that this is a serious problem that is now driving earthquake safety work.”
　　The Telegraph also reports that the government responded to the warnings by building an emergency response center at the Fukushima Daiichi plant designed to resist magnitude-7.0 earthquakes. Friday's earthquake, originally named a magnitude-8.9 shock, has since been upgraded to magnitude-9.0.
　　Other nuclear experts state IAEA officials had willingly ignored lessons from the Chernobyl disaster to protect the nuclear industry's expansion, reports Bloomberg. “After Chernobyl, all the force of the nuclear industry was directed to hide this event, for not creating damage to their reputation,”Russian nuclear accident specialist Iouli Andreyev tells Reuters, before noting that radiation from spent fuel rods（棒）stored close to reactors at Fukushima looked like an example of putting profit before safety. “The Japanese were very greedy, and they used every square inch of the space. But when you have a dense(密集的) placing of spent fuel in the basin, you have a high possibility of fire if the water is removed from the basin.”
