With fears of a possible nuclear meltdown in Japan continuing to escalate, evidence that the nation received warnings over the stability of its power plants from an international watchdog more than two years ago has emerged via a new round of diplomatic cables accessed by WikiLeaks.
An official from the International Atomic Energy Agency (IAEA) said in December 2008 that safety rules were outdated, and strong earthquakes would pose a "serious problem" for the power stations.
A U.S. embassy cable quoted an unnamed expert who expressed concern that guidance on how to protect nuclear power stations from earthquakes had only been updated three times in the past 35 years. The document states: "He explained that safety guides for seismic safety have only been revised 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 exceeded the design basis for some nuclear plants, and that this is a serious problem that is now driving seismic safety work."
Meanwhile in Australia:
"RMIT Chancellor Dr Ziggy Switkowski has been gently spinning the issue, repeatedly reassuring us that lessons will be learned, improvements will be made. However, history shows that nuclear lessons are not properly learned. The OECD's Nuclear Energy Agency notes that lessons may be learned but too often they are subsequently forgotten, or they are learned but by the wrong people, or they are learned but not acted upon. The Nuclear Energy Agency says the pattern of the same type of accident recurring time and time again at different nuclear plants needs to be "much improved".
The situation in Japan illustrates the point − it has become increasingly obvious over the past decade that greater protection against seismic risks is necessary, but the nuclear utilities haven't wanted to spend the money and the Japanese nuclear regulator and the government haven't forced the utilities to act."
