Operators of a quake-crippled nuclear plant in Japan again deployed military helicopters today in a bid to douse overheating reactors, as US officials warned of the rising risk of a catastrophic radiation leak from spent fuel rods.Television images have shown a Japanese military helicopter dumping water from a huge bucket onto the stricken Fukushima nuclear power plant. NHK also reports that more helicopters will be sent to douse the plant.
While officials were scrambling to contain the nuclear crisis with a patchwork of fixes, the top US nuclear regulator warned that one reactor cooling pool for spent fuel rods may have run dry and another was leaking."We believe that around the reactor site there are high levels of radiation," Gregory Jaczko, head of the Nuclear Regulatory Commission, told a House Energy and Commerce subcommittee hearing.
"It would be very difficult for emergency workers to get near the reactors. The doses they could experience would potentially be lethal doses in a very short period of time."Health experts said panic over radiation leaks from the Daiichi plant was also diverting attention from other threats to survivors of last Friday's 9.0 magnitude earthquake and tsunami, such as the cold weather and access to fresh water.
The head of the world's nuclear watchdog, meanwhile, said it was not accurate to say things were "out of control" in Japan, but the situation was "very serious", with core damage to three units at the plant, around 240km north of Tokyo.The latest images from the plant showed severe damage to some of the buildings after several blasts.
A stream of gloomy warnings and reports on the Japan crisis from experts and officials around the world triggered a swoon in global financial markets, with the Japanese yen surging to all-time highs against the dollar and all three major stock indexes slumping on fears of slower worldwide growth.
Japanese Finance Minister Yoshihiko Noda on today blamed speculation for the yen's surge and repeated his warning that he would closely watch market action. Japan's Nikkei average slumped on opening on Thursday, and an hour after opening was down nearly 4 percent.G7 Finance ministers will hold a conference call later on Thursday to discuss steps to help Japan cope with the financial and economic impact of the disaster, a source said.

Bulldozers to clear way for firetrucks
Japan's government said radiation levels outside the plant's gates were stable but, in a sign that it was overwhelmed, appealed to private companies to help deliver supplies to tens of thousands of people evacuated from around the complex.
"People would not be in immediate danger if they went outside with these levels. I want people to understand this," chief cabinet secretary Yukio Edano told a news conference, referring to people living outside a 30-km exclusion zone.Tokyo Electric Power Co (Tepco) officials said bulldozers attempted to clear a route to the reactor so firetrucks could gain access and try to cool the facility using hoses.
Company officials also said they had high hopes of getting limited power to the facility to help pump water needed to cool reactors and the spent fuel rods that have been overheating.
High radiation levels yesterday prevented a helicopter from dropping water into the No 3 reactor to try to cool its fuel rods after an earlier explosion damaged the unit's roof and cooling system, but they managed on a second attempt today.
The plant operator described No 3 - the only reactor at that uses plutonium in its fuel mix - as the "priority".Plutonium, once absorbed in the bloodstream, can linger for years in bone marrow or liver and lead to cancer.If cooling operations do not proceed well, the situation will "reach a critical stage in a couple of days", said an official with the government's Nuclear and Industrial Safety Agency.
The situation at No 4 reactor, where the fire broke out, was "not so good", Tepco added, while water was being poured into reactors No 5 and 6, indicating the entire six-reactor facility was now at risk of overheating."Getting water into the pools of the No 3 and No 4 reactors is a high priority," Said Hidehiko Nishiyama, a senior official at Japan's Nuclear and Industrial Safety Administration."It could become a serious problem in a few days," he said.
Embassies urge citizens to leave
Scores of flights to Japan have been halted or rerouted and air travellers are avoiding Tokyo for fear of radiation.On Thursday the US Embassy in Tokyo urged citizens living within 80km of the Daiichi plant to evacuate or remain indoors "as a precaution", while Britain's foreign office urged citizens "to consider leaving the area".
The warnings were not as strong as those issued earlier by France and Australia, which urged nationals in Japan to leave the country. Russia said it planned to evacuate families of diplomats on Friday.In a demonstration of the qualms about nuclear power that the crisis has triggered around the globe, China announced that it was suspending approvals for planned plants and would launch a comprehensive safety check of facilities.
China has about two dozen reactors under construction and plans to increase nuclear electricity generation about seven-fold over the next 10 years.Russian President Dmitry Medvedev said nuclear power was safe provided power stations were built in the right place and designed and managed properly. Russia ordered checks at nuclear facilities on Tuesday.
In Japan, the plight of hundreds of thousands left homeless by the earthquake and devastating tsunami that followed worsened following a cold snap that brought snow to worst-affected areas.Supplies of water and heating oil are low at evacuation centres, where many survivors wait bundled in blankets.
About 850,000 households in the north were still without electricity in near-freezing weather, Tohuku Electric Power Co said, and the government said at least 1.5 million households lack running water.“It's cold today so many people have fallen ill, getting diarrhea and other symptoms," said Takanori Watanabe, a Red Cross doctor in Otsuchi, a low-lying town where more than half the 17,000 residents are still missing.
The National Police Agency said it has confirmed 4,314 deaths in 12 prefectures as of midnight Wednesday, while 8,606 people remained unaccounted for in six prefectures.
In another sign of international frustration at the pace of updates from Japan, Yukiya Amano, director general of the International Atomic Energy Agency, said he would fly to Japan today to glean first-hand information on the crisis.
Low radiation in Tokyo, but streets deserted
Several experts said the Japanese authorities were underplaying the severity of the incident, particularly on a scale called INES used to rank nuclear incidents. The Japanese have so far rated the accident a four on a one-to-seven scale, but that rating was issued on Saturday and since then the situation has worsened dramatically.
France's nuclear safety authority ASN said on Tuesday it should be classed as a level-six incident.At its worst, radiation in Tokyo reached 0.809 microsieverts per hour on Tuesday - 10 times below what a person would receive if exposed to a dental x-ray. Early Thursday, radiation levels were barely above average.But many Tokyo residents stayed indoors. Usually busy streets were nearly deserted. Many shops and offices were closed.

BOJ has already expanded their QE program from 5 to 10 Trillion Yen (120billion), to have the scale of QE 2 in the US, they need to implement the full size 30 Trillion Yen. As the government already indebted up to 200% of GDP, they are treading a fine line going forward. Japanese corporate, government and individuals own up to 850 billion worth US Treasuries. If they need to dip into their savings for reconstruction. Keep an eye for the yield curve on US debts.
