Blast at Japan nuke plant, toll likely to rise

Iwaki (Japan), March 12 2011: An explosion at a nuclear power station on Saturday destroyed a building housing the reactor, but a radiation leak was decreasing despite fears of a meltdown from damage caused by a powerful earthquake and tsunami, officials said.

Government spokesman Yukio Edano said the explosion destroyed the exterior walls of the building where the reactor is placed, but not the actual metal housing enveloping the reactor.

That was welcome news for a country suffering from Friday's double disaster that pulverized the northeastern coast, leaving at least 574 people dead by official count.

The scale of destruction was not yet known, but there were grim signs that the death toll could soar.

One report said four whole trains had disappeared Friday and still not been located.

Local media reports said at least 1,300 people may have been killed.

Edano said the radiation around the Fukushima Daiichi plant had not risen after the blast, but had in fact decreased.

He did not say why that was so.

The pressure in the reactor was also decreasing after the blast, he said.

The explosion was preceded by puff of white smoke that gathered intensity until it became a huge cloud enveloping the entire facility, located in Fukushima, 30 kilometers from Iwaki.

After the explosion, the walls of the building crumbled, leaving only a skeletal metal frame.

Tokyo Power Electric Co., the utility that runs the Fukushima Daiichi plant, said four workers suffered fractures and bruises and were being treated at a hospital.

"We have confirmed that the walls of this building were what exploded, and it was not the reactor's container that exploded," said Edano.

The trouble began at the plant's Unit 1 after the massive 8.9-magnitude earthquake and the tsunami it spawned knocked out power there, depriving it of its cooling system.

The concerns about a radiation leak at the nuclear power plant overshadowed the massive tragedy laid out along a 2,100-kilometer stretch of the coastline where scores of villages, towns and cities were battered by the tsunami, packing 23-feet high waves.

It swept inland about 10 kilometers in some areas, swallowing boats, homes, cars, trees and everything else.

"The tsunami was unbelievably fast," said Koichi Takairin, a 34-year-old truck driver who was inside his sturdy four-ton rig when the wave hit the port town of Sendai.

"Smaller cars were being swept around me," he said.

"All I could do was sit in my truck" .

His rig ruined, he joined the steady flow of survivors who walked along the road away from the sea and back into the city on Saturday.

Smashed cars and small airplanes were jumbled up against buildings near the local airport, several kilometers from the shore.

Felled trees and wooden debris lay everywhere as rescue workers coasted on boats through murky waters around flooded structures, nosing their way through a sea of debris.

According to official figures, 586 people are missing and 1,105 injured.

In addition, police said between 200 and 300 bodies were found along the coast in Sendai, the biggest city in the area near the quake's epicenter.

The true scale of the destruction was still not known more than 24 hours after the quake since washed-out roads and shut airports have hindered access to the area.

An untold number of bodies were believed to be buried in the rubble and debris.

Meanwhile, the first wave of military rescuers began arriving by boats and helicopters.

Prime Minister Naoto Kan said 50,000 troops joined rescue and recovery efforts, aided by boats and helicopters.

Dozens of countries also offered help.

President Barack Obama pledged US assistance following what he called a potentially "catastrophic" disaster.

He said one US aircraft carrier was already in Japan and a second was on its way.

Washington has also dispatched urban search and rescue teams, according to US Ambassador John Roos.

More than 215,000 people were living in 1,350 temporary shelters in five prefectures, or states, the national police agency said.

Since the quake, more than 1 million households have not had water, mostly concentrated in northeast.

Some 4 million buildings were without power.

About 24 per cent of electricity in Japan is produced by 55 nuclear power units in 17 plants and some were in trouble after the quake.

Japan declared states of emergency at two power plants after their units lost cooling ability.

Although the Govt spokesman played down fears of radiation leak, the Japanese nuclear agency spokesman Shinji Kinjo acknowledged there were still fears of a meltdown.

A "meltdown" is not a technical term.

Rather, it is an informal way of referring to a very serious collapse of a power plant's systems and its ability to manage temperatures.

Yaroslov Shtrombakh, a Russian nuclear expert, said a Chernobyl-style melt-down was unlikely.

"It's not a fast reaction like at Chernobyl," he said.

"I think that everything will be contained within the grounds, and there will be no big catastrophe." In 1986, the Chernobyl nuclear reactor exploded and caught fire, sending a cloud of radiation over much of Europe.

The reactor in trouble has already leaked some radiation: Before the explosion, operators had detected eight times the normal radiation levels outside the facility and 1,000 times normal inside Unit 1's control room.

Technologically advanced Japan is well prepared for quakes and its buildings can withstand strong jolts, even a temblor like Friday's, which was the strongest the country has experienced since official records started in the late 1800s.What was beyond human control was the killer tsunami that followed.

Japan's worst previous quake was a magnitude 8.3 temblor in Kanto that killed 143,000 people in 1923, according to the USGS.

A magnitude 7.2 quake in Kobe killed 6,400 people in 1995 .

Japan lies on the " Ring of Fire", an arc of earthquake and volcanic zones stretching around the Pacific where about 90 per cent of the world's quakes occur, including the one that triggered the Dec.

26, 2004, Indian Ocean tsunami that killed an estimated 230,000 people in 12 countries.

A magnitude-8.8 quake that shook central Chile in Feb 2010 also generated a tsunami, killing 524 people.
