Japan and France have been valued differently than the accident at the Fukushima nuclear plant. While Nipponese authorities consider, for now, the severity of 4 on the International Events Scale (INES), ie, "accident consequences at the local" French nuclear agency believes that the level is already 6 (" mportant accident ").
If you ignore the assessment of Japan, the severity of the accident would be below the rank of Three Mile Island in 1979 in the U.S., which caused no fatalities but had economic consequences , environmental issues and markedly reduced public confidence in nuclear power plants. Severity level 4, is also the same as that awarded to Tokaimura accident in 1999-until a few days ago considered the worst nuclear disaster in Japan in the tanks of the plant workers died and 440 were uranium affected by radiation.
The 6 as INES a "major accident", has only been reached twice. In both cases the nuclear plant the former Soviet Union: the first, less known, was the explosion at the nuclear complex Kyshtym (Mayak, Russia) in 1957 and who died hundreds of people and remained hidden for 30 years. The second was the catastrophe of Chernobyl , which in 1986 reached the highest level of the INES scale (the 7).
The INES scale has 7 levels (ranging from "no safety significance" to "major accident") and applied since 1990 to "inform the public quickly and consistently the importance from the point of view safety events associated with radiation sources "in 60 states, according to the website of the International Atomic Energy Agency (IAEA).
Some experts indicated consulted if it is normal to make a first assessment prudent, and took for granted that the severity of the accident was officially raise sometime. The Council radiologist Scientific Research (CSIC) Eduard Rodríguez-Farré noted that news of the recent explosions at the plant would advise increased to 6 alarm level and even qualified Fukushima "a Chernobyl in slow motion" .
