Fukushima: Japan scrambled to avert a meltdown at a stricken nuclear reactor on Monday after a second hydrogen explosion rocked the facility, just days after a devastating earthquake and tsunami that killed at least 10,000 people.
Roads and rail, power and ports have been crippled across much of Japan’s northeast and estimates of the cost of the multiple disasters have leapt to as much as $ 170 billion. Analysts said the economy could even tip back into recession.
Japanese stocks closed down more than six per cent, the biggest fall since the height of the global financial crisis in 2008.
Rescue workers combed the tsunami-battered region north of Tokyo for survivors and struggled to care for millions of people without power and water in what Prime Minister Naoto Kan has dubbed his country’s worst crisis since World War Two.
Officials say at least 10,000 people were likely killed in the 8.9-magnitude earthquake and tsunami that followed it. Kyodo news agency reported that 2,000 bodies had been found on Monday in two coastal towns alone.
“It’s a scene from hell, absolutely nightmarish,” said Patrick Fuller of the International Red Cross Federation from the town of Otsuchi.
“The situation here is just beyond belief, almost everything has been flattened. The government is saying that 9,500 people, more than half of the population could have died and I do fear the worst.”
Crucially, officials said the thick walls around the radioactive cores of the damaged reactors at the nuclear power plant appeared to be intact after the hydrogen blast, the second there since Saturday.
The big fear is of a major radiation leak from the complex in Fukushima, 240 km (150 miles) north of Tokyo, where engineers have been battling since the weekend to prevent a meltdown in three reactors.
The core container of the No. 3 reactor was intact after the explosion, the government said, but it warned those still in the 20-km (13-mile) evacuation zone to stay indoors. The plant operator, Tokyo Electric Power Co (TEPCO), said 11 people had been injured in the blast.
Kyodo said 80,000 people had been evacuated from the zone, joining more than 450,000 other evacuees from quake and tsunami-hit areas in the northeast.
“Everything I’ve seen says that the containment structure is operating as it’s designed to operate. It’s keeping the radiation in and it’s holding everything in, which is the good news,” said Murray Jennex, of San Diego State University.
“This is nothing like a Chernobyl … At Chernobyl (in Ukraine in 1986) you had no containment structure – when it blew, it blew everything straight out into the atmosphere.”
Officials said on Sunday that three nuclear reactors in Fukushima were at risk of overheating, raising fears of an uncontrolled radiation leak.
Engineers worked desperately to cool the fuel rods. If they fail, the containers that house the core could melt, or even explode, releasing radioactive material into the atmosphere.
Nuclear experts said it was probably the first time in the industry’s 57-year history that sea water has been used in this way, a sign of how close Japan may be to a major accident.
“Injection of sea water into a core is an extreme measure,” Mark Hibbs of the Carnegie Endowment for International Peace. “This is not according to the book.”
The nuclear accident, the worst since Chernobyl, sparked criticism that authorities were ill-prepared and the threat that could pose to the country’s nuclear power industry.
A Japanese official said before the blast that 22 people were confirmed to have suffered radiation contamination and up to 190 may have been exposed. Workers in protective clothing used hand-held scanners to check people arriving at evacuation centres.
US warships and planes helping with relief efforts moved away from the coast temporarily because of low-level radiation. The US Seventh Fleet described the move as precautionary.
South Korea, Hong Kong, Singapore and the Philippines said they would test Japanese food imports for radiation.
Almost 2 million households were without power in the north, the government said. There were about 1.4 million without running water. Tens of thousands of people are missing.
The town of Otsuchi in Iwate prefecture was obliterated.
“After my long career in the Red Cross where I have seen many disasters and catastrophes, this is the worst I have ever seen. Otsuchi reminds me of Osaka and Tokyo after the Second World War when everything was destroyed and flattened,” Japan Red Cross President Tadateru Konoe told Reuters during a visit to the coastal town.
Whole villages and towns have been wiped off the map by Friday’s wall of water, triggering an international humanitarian effort of epic proportions.
“When the tsunami struck, I was trying to evacuate people. I looked back, and then it was like the computer graphics scene I’ve seen from the movie Armageddon. I thought it was a dream ? it was really like the end of the world,” said Tsutomu Sato, 46, in Rikuzantakata, a town on the northeast coast.
Estimates of the economic impact are only now starting to emerge.
Hiromichi Shirakawa, chief economist for Japan at Credit Suisse, said in a note to clients that the economic loss will likely be around 14-15 trillion yen ($ 171-183 billion) just to the region hit by the quake and tsunami.
Even that would put it above the commonly accepted cost of the 1995 Kobe quake which killed 6,000 people.
The earthquake has forced many firms to suspend production and shares in some of Japan’s biggest companies tumbled on Monday, with Toyota Corp dropping almost 8 per cent . Shares in Australian-listed uranium miners also dived.
“When we talk about natural disasters, we tend to see an initial sharp drop in production … then you tend to have a V-shaped rebound. But initially everyone underestimates the damage,” said Michala Marcussen, head of global economics at Societe Generale.
Risk modelling company AIR Worldwide said insured losses from the earthquake could reach nearly $ 35 billion.
Global companies from semiconductor makers to shipbuilders faced disruptions to operations after the quake and tsunami destroyed vital infrastructure, damaged ports and knocked out factories supplying everything from high-tech components to steel.
The Bank of Japan offered a combined 15 trillion yen ($ 183 billion) to the banking system earlier in the day to soothe market jitters.
Finance Minister Yoshihiko Noda said authorities were closely watching the yen after the currency initially rallied on expectations of repatriations by insurers and others. The currency later reversed course in volatile trading.
The earthquake was the fifth most powerful to hit the world in the past century. It surpassed the Great Kanto quake of September 1, 1923, which had a magnitude of 7.9 and killed more than 140,000 people in the Tokyo area.
