As the IAEA Director General Emeritus, Hans Blix put it “A nuclear accident anywhere is an accident everywhere”. Fukushima revealed that no one state is immune from fallacies that resulted both before and after the nuclear accident. That will be also true with any nuclear terrorism event, which we have been spared thus far.

“The latest chess match between Iran and six major powers in Baghdad ended last week without any declared breakthrough. This is not entirely surprising. Talks were unlikely to make significant headway with Iran offering to sacrifice a pawn -- 20 percent enriched uranium -- in exchange for the queen -- the lifting of oil sanctions,” Olli Heinonen, former deputy director-general of the IAEA and senior fellow at the Belfer Center, writes in a Foreign Policy op-ed. “In the meantime, the International Atomic Energy Agency's (IAEA) report on Iran, released May 25, reveals new information, most notably the presence of uranium particles enriched to 27 percent, well above the declared 20 percent enrichment level at the Fordow underground enrichment plant. Right now, the key question that the IAEA is trying to answer is how much uranium was enriched to 27 percent and over what period of time the enrichment took place.”

This week, when the leaders of the G8 industrial democracies gather in France, their meeting will include discussions of what steps must be taken to strengthen global nuclear safety and global nuclear security  in the aftermath of the tragedy at Fukushima. The Belfer Center's Matthew Bunn and Olli Heinonen suggest new actions the world community should take in five key areas in order to prevent another Fukushima.
