TOKYO Japan underestimated the risk of tsunamis and required monitor public health and safety of workers to closely following the crisis on the Fukushima Daiichi nuclear power a team of international safety inspectors of the world's largest nuclear disaster said in a preliminary examination since Chernobyl.
The report, an International Atomic Energy Agency (IAEA) team under the leadership of Britain's top nuclear safety official Mike Weightman, highlighted some of the well documented weaknesses, which on the crisis in Fukushima contributed, if the plant, 150 km north of Tokyo, by a massive earthquake and then a tsunami in quick succession was taken on 11 March.
Those start with an error, a tsunami to plan, that would overrun the 19-foot break wall of Fukushima and knock out back-up electrical generators to four reactors, despite several predictions of an agency and operator Tokyo Electric Power Co.'s own scientists of the Government, which is such a danger was.
The IAEA team said Japan's crisis lessons for the nuclear industry around the world offered including, that operators regularly the risks of natural disasters should review and, that should "hardened" emergency response center to be established with accidents.

"Nuclear plant designers and operators should evaluate appropriately and provide protection against the risks of all natural hazards."
The report praised the general response to the disaster, however, say that it had been exemplary.
Story: Excessive radiation for two Fukushima employed?Goshi Hosono, an advisor of Prime Minister Naoto Kan, accepts the report, marking the first step in the effort by the Japanese authorities to show that the lessons from Fukushima can certainly be applied to its remaining nuclear reactors.
Hosono said that the Government would have to review nuclear regulatory framework.
Playbook "not" work
The IAEA team present the results of a Ministerial Conference on nuclear safety in Vienna on June 20-24.
"We had a textbook, but it didn't work," said Tatsujiro Suzuki, a nuclear expert and Vice-Chairman of the Japan Atomic Energy Commission.
The economic stakes are high. Japan is only 19 of his pre-Fukushima tally 54 reactors working.
Unless local officials that Tokyo has a plan to the other resistant against the kind of blackout that plunged Fukushima in meltdown can be persuaded, more plants offline for maintenance will fall.
In the worst case all could Japan's reactors shut down in mid 2012. That would take 30 percent of the country's power generation and increase the risk of deep in the, close to permanent power rationing, officials say.
The Fukushima accident has forced more than 80,000 residents from their homes and deepening workers raised concerns about the safety operation of nearby children, fighting for the reactors and to stabilize the food supply as radiated from the site of water leaks.
In the report, the IAEA team Japan calls follow up monitoring of workers and the public health.
The crisis has also redirected, attention and resources of the reconstruction after the earthquake and tsunami, about 24,000 people in North Japan Coast killed.
'Very stupid'
Experts who have reviewed the Fukushima incident say, the IAEA report is certainly a starting point in the debate about what to be done in a country nuclear plants where the risks of earthquakes must still be understood.
"There are aspects of the planning for the security of the Fukushima plant, which are very stupid, in retrospect, and show a lack of imagination," said Kim Kearfott, a University of Michigan nuclear safety expert who toured their own this week Japan. "The nuclear industry can do better than this."
As the uranium fuel in the reactor No. 1 Kulissenwechsel started heating towards meltdown on 11 March, Tokyo Electric (Tepco) officials at the failures of the most important safety equipment for the loss of the power of the plant.
Measuring empty of Fukushima to officials in Tokyo monitoring the expected radiation hazard related problem. Complicated software to the expected plume of debris model an explosion of Fukushima had set up rather it with exact dates as gross assumptions.
Early on March 12, officials in the Ministry of education and technology had fixed the glitch and submit the projected radiation show Prime Minister kan, but the data was never released to the public.
In the meantime it was dangerously unclear, which was on the ground in Fukushima. TEPCO of President was in China, the utility of President was grounded in the Western Japan on a personal journey. Sakae Muto, the ranking Tepco official, spent the night of the quake with mayors of small towns in the vicinity of Fukushima, you notice of the accident, rather than the command center accession pressed.
The plant chief operating officer of Masao Yoshida, ignored to stop an order injection sea water in the reactor No. 1 due to a user request from kan's Office. Experts say that Yoshida made the right call, but say the confusion which highlighted major problems in the early response to the accident.
"It was impossible, that works as it was set up had the system," said Suzuki, who believes that Japan's nuclear industry must now show it manage and contain the most incredible accident at all its remaining nuclear reactors can public confidence to win. ", If they can demonstrate that it will be very difficult."
Others say that Japan must show, that he at the toughest Council critics, including long delayed steps, make independent of the most politically powerful utility industry to its nuclear regulatory agency acts.
"Japanese atomic operations must be updated on the International Council," said Kearfott. "Much of this advice was ignored in the past."
