As reported in Mainichi Shinbun Japanese, the IAEA report will state the obvious, nothing new, nothing to contradict what TEPCO and the Japanese government have been insisting. And a generous praise for the Japanese government.
The IAEA findings to be included in their report, from Mainishi Shinbun Japanese (2:50AM JST 6/1/2011):
Danger of tsunami was underestimated. People who build nuclear power plants and people who operate the plants should factor in the impact of "natural disasters" more;
Nuclear and Industrial Safety Agency (regulatory agency for the nuclear industry) should be more independent;
Initial response should be better thought out;
Hydrogen is dangerous;
Dedicated and determined skilled workers at the plant;
TEPCO's "roadmap" needs to be revised as the situation develops, and some form of international cooperation may be possible;
The international community should learn from the Fukushima I accident as a lesson on nuclear safety.
And
The Japanese government's response to the accident has been "wonderful and well-organized".
No kidding. The IAEA had better inform the residents of Japan about that very quickly; they may already have gotten some funny ideas about the effectiveness of their government in dealing with the on-going nuclear crisis.
The IAEA team is scheduled to visit the Prime Minister's Residence on June 1, and hand the report to the Prime Minister.
