Radiation levels rise above limit at quake-hit nuclear plant in Japan
Thousands of Japanese fled the vicinity of an earthquake-crippled nuclear plant after a radiation leak and authorities faced a fresh threat on Sunday with the failure of the cooling system in a second reactor.
Operator Tokyo Electric Power (TEPCO) said it was preparing to vent steam to relieve pressure in the No.3 reactor at the plant 240 km (150 miles) north of Tokyo -- which would release a small amount of radiation -- following an explosion and leak on Saturday from the facility's No. 1 reactor.
As strong aftershocks continued to shake Japan's main island, the desperate search pressed on for survivors from Friday massive earthquake and tsunami and the death toll was expected to rise.
Thousands spent another freezing night huddled over heaters in emergency shelters along the northeastern coast, a scene of devastation after the 8.9 magnitude quake sent a 10-metre (33-foot) wave surging through towns and cities in the Miyagi region.
"It's hard to even imagine the scale of it," a resident said. "I came to Miyagi during the last earthquake as well to help, but once there is water involved, it becomes a whole different story. It's hard to think about."
Kyodo news agency said the number of dead or unaccounted was expected to exceed 1,800. It also reported there had been no contact with around 10,000 people in one town, more than half its population.
The government insisted radiation levels were low following Saturday's explosion, saying the blast had not affected the reactor core container, and the International Atomic Energy Agency (IAEA) said it had been told by Japan that levels "have been observed to lessen in recent hours".
But Japan's nuclear safety agency said the number of people exposed to radiation from the Fukushima Daiichi plant could reach 160. Workers in protective clothing were scanning people arriving at evacuation centres for radioactive exposure.
"They are working on relieving pressure and pumping in water into the No. 3 reactor," Chief Cabinet Secretary Yukio Edano told a news briefing.
"This will result in some radiation leakage, although at a level that won't affect peoples' health. It will help stabilise the situation." He also said radiation from the No. 1 reactor was "low enough not to affect people's health".
Officials ordered the evacuation of a 20-km (12-mile) radius zone around the plant and 10 km (6 miles) around another nuclear facility close by. Around 140,000 people had left the area, the IAEA said, while authorities prepared to distribute iodine to protect people from radioactive exposure.
"There is radiation leaking out, and since the possibility (of being exposed) is high, it's quite scary," said Masanori Ono, 17, standing in line on Saturday to be scanned for radiation at an evacuation centre in Fukushima prefecture.
The government, which took power led by the Democratic Party of Japan for the first time less than two years ago, was already facing criticism.
"Crisis management is incoherent," blared a headline in the Asahi newspaper, charging that information disclosure and instructions to expand the evacuation area around the troubled plant were too slow.
"Every time they repeated 'stay calm' without giving concrete data, anxiety increased," it quoted an unidentified veteran party lawmaker as saying.
Edano said the government expected the 200 billion yen ($2.4 billion) budget reserve for the current fiscal year to cover its response to the crisis. "We cannot comment on the size of the necessary extra budget for the next fiscal year (starting in April) for now, it will need deliberations in parliament."
In Europe, environmentalists seized upon the accident to press demands for an end to nuclear power. Up to 60,000 protesters formed a 45-km (27-mile) human chain in Germany to denounce the government's policy of extending the life of nuclear plants.
Helicopters from Japan's Self-Defence Forces lifted 195 people from retirement homes and hospitals inside the exclusion zone.
Before news of the problem with reactor No. 3, the nuclear safety agency said the plant accident was less serious than both the Three Mile Island accident in 1979 and the 1986 Chernobyl nuclear disaster.
An official at the agency said it had rated the incident a 4 according to the International Nuclear and Radiological Event Scale (INES). Three Mile Island was rated 5 while Chernobyl was rated 7 on the 1 to 7 scale, the official said.
However, Kyodo news agency later reported that raidation levels at the Daiichi plant had risen above their limit.
Along the northeast coast, rescue workers searched through the rubble of destroyed buildings, cars and boats, looking for survivors in hardest-hit areas such as Sendai, 300 km (180 miles) northeast of Tokyo.
Aerial footage showed buildings, trains and even light aircraft strewn like children's toys after powerful walls of seawater swamped areas around Sendai.
In Iwanuma, not far from Sendai, nurses and doctors were rescued on Saturday after spelling S.O.S. on the rooftop of a partially submerged hospital, one of many desperate scenes. In cities and towns, worried relatives checked information boards on survivors at evacuation centres.
Dazed residents hoarded water and huddled in makeshift shelters in near-freezing temperatures.
"All the shops are closed, this is one of the few still open. I came to buy and stock up on diapers, drinking water and food," Kunio Iwatsuki, 68, told Reuters in Mito city, where residents queued outside a damaged supermarket for supplies.
Kyodo said about 300,000 people were evacuated nationwide, many seeking refuge in shelters, wrapped in blankets, some clutching each other sobbing.
It said 5.5 million people were without power, while 3,400 buildings had been destroyed or damaged. Four trains were unaccounted for after the tsunami.
In Tokyo, the usually bustling central districts were deserted on Saturday night, and the few in bars and restaurants were glued to television coverage of the disaster.
"Even in the bar we kept staring at the news," said Kasumi, a 26-year-old woman meeting a friend for a drink in the central district of Akasaka. "I looked at the tsunami swallowing houses and it seemed like a film."
Plant operator TEPCO has had a rocky past in an industry plagued by scandal. In 2002, the president of the country's largest power utility was forced to resign along with four other senior executives, taking responsibility for suspected falsification of nuclear plant safety records.
Many Japanese flooded social networking sites with worries about the plant.
"I can't trust TEPCO," said a person with the handlename Tanuki Atsushi on mixi, the Japanese social networking site.
The earthquake and tsunami, and now the radiation leak, present Japan's government with its biggest challenge in a generation.
The disaster struck as the world's third-largest economy had been showing signs of reviving from an economic contraction in the final quarter of last year. It raised the prospect of major disruptions for many key businesses and a massive repair bill running into tens of billions of dollars.
Foreign countries have started to send disaster relief teams to help Japan, with the United Nations sending a group to help coordinate work.
The earthquake was the fifth most powerful to hit the world in the past century. It surpassed the Great Kant quake of Sept. 1, 1923.
