Japan races to find tsunami dead despite radiation
Minami Soma: Japanese police raced on Thursday to find thousands of missing bodies before they decompose along a stretch of tsunami-pummelled coast that has been largely off-limits because of a radiation-leaking nuclear plant.
Nearly a month after a 9.0-earthquake generated the tsunami along Japan`s northeastern coast, more than 14,700 people are still missing. Many of those may have been washed out to sea and will never be found.
In the days just after the March 11 disaster, searchers gingerly picked through mountains of tangled debris, hoping to find survivors. Heavier machinery has since been called in, but unpredictable tides of radiation from the Fukushima Daiichi nuclear complex have slowed progress and often forced authorities to abandon the search, especially within a 12-mile (20-kilometer) evacuation zone around the plant.
Officials now say there`s not much time left to find and identify the dead, and are ramping up those efforts.
"We have to find bodies now as they are decomposing," said Ryoichi Tsunoda, a police spokesman in Fukushima prefecture, where the plant is located. "This is a race against time and against the threat of nuclear radiation."
Up to 25,000 people are believed to have been killed, of which 12,500 have been confirmed. There is expected to be some overlap in the dead and missing tolls because not all of the bodies have been identified.
Recent progress at the plant — which the tsunami flooded — appears to have slowed the release of radiation. Early Wednesday, technicians there plugged a crack that had been gushing contaminated water into the Pacific. Radiation levels in waters off the coast fell dramatically later in the day, though contaminated water continues to pool throughout the complex, often thwarting work there.
After notching that rare victory, technicians began pumping nitrogen into the chamber of reactor on Thursday in order to reduce the risk of a hydrogen explosion.
Three hydrogen blasts rocked the complex in the days immediately following the tsunami, which knocked out vital cooling systems. An internal report from March 26 by the US Nuclear Regulatory Commission warned such explosions could occur and recommended adding nitrogen. The gas will be injected into all three of the troubled reactors over the next six days.
Radiation has stabilised somewhat in recent days, Tsunoda said, and a small team resumed the search in Fukushima prefecture on Sunday. But the operation dramatically increased on Thursday, when 330 police and 650 soldiers fanned out, wearing white protective gear from head to toe. They are concentrating on areas between six and 12 miles (10 and 20 kilometres) from the plant — all of which are within a zone evacuated because of radiation fears.
Teams patrolled deserted streets on the fringes of Minami Soma, a city just on the edge of the no-go zone that was completely flattened in the crush of water. One body was pulled out of the rubble Thursday morning.
"We just got started here this morning, so we expect there will be many more," said one officer, who requested anonymity because he was not authorised to speak to the media.
More than 1,000 people are missing in the city alone.
"I believe the search will continue until they find as many of the missing as they can, but we fear many of the missing were washed out to sea or are buried under rubble," said Takamitsu Hoshi, a city official. "We haven`t been able to do much searching at all because of the radiation concerns. It was simply too dangerous."
Last weekend, US and Japanese troops conducted a massive, all-out search of coastal waters, finding about 70 bodies over three days. While such operations haven`t stopped completely, they`ll be severely limited going forward. The death toll for the 2004 Asian tsunami includes tens of thousands of bodies that were never found, likely sucked out to sea.
Meanwhile, the US State Department confirmed the death of Montgomery Dickson — the second American confirmed killed in the disaster. It gave no other details.
While some progress has been made at the nuclear complex in recent days, the confidential assessment from the US regulator noted that plant operator Tokyo Electric Power Co still faces several challenges. It said that salt from seawater that had been used as a coolant in the early days of the crisis is probably blocking circulation pathways, making it harder to stabilise overheating fuel.
The document — prepared by the US agency`s Reactor Safety Team, which is helping the Japanese government and TEPCO — offers new details on the conditions of the damaged cores in the three troubled reactors. For instance, it warned that the weight of water pumped into the reactors could make their vessels more vulnerable to rupture in an aftershock from the earthquake.
On Thursday, Japan`s Nuclear and Industrial Safety Agency acknowledged that there might be some damage to the pressure vessels that hold the reactor cores.
"We do not know exactly what has happened to the pressure vessels," said Hidehiko Nishiyama.
But he added that officials thought there were only small cracks or scratches since more severe damage would have led to a significant drop in pressure.
The US report was intended for American regulators working with their Japanese counterparts and was first reported by the New York Times. The commission noted on Wednesday that the document was a "snapshot" of the situation at the plant on March 26 and does not necessarily reflect current understanding.
