Workers at Japan’s crippled nuclear plant yesterday struggled to stop a radioactive water leak into the Pacific, as the government warned the facility may spread contamination for months.
Along the tsunami-ravaged coast, 25,000 Japanese and US military and rescue crew completed a massive three-day search for bodies, more than three weeks after the catastrophe struck.
While cherry blossoms opened in Tokyo, temperatures plunged again, leaving tens of thousands of homeless shivering in evacuation camps along the ravaged northeast coast of Japan’s main Honshu island.
There was no quick end in sight for the world’s worst nuclear emergency since the 1986 Chernobyl disaster, warned a government lawmaker who has advised Prime Minister Naoto Kan on the crisis at the six-reactor plant.
“This is going to be a long battle,” said Goshi Hosono, who highlighted the threat from 4.5-metre-long spent fuel rods that remain volatile for months and need to be cooled in pools with circulating water.
“The biggest challenge at this plant is that there are more than 10,000 spent fuel rods,” Mr Hosono said on Fuji TV. “It will take a very long time to reprocess them, and we sincerely apologise for that.
“It is unacceptable that radioactive substances keep being released, causing anxiety among the people. Probably it will take several months before we reach the point” where all radiation leaks stop, he said.
Outside the headquarters of plant operator Tokyo Electric Power Company (Tepco), about 100 protesters, outnumbered by police, shouted: “No more nuclear plants!” and “Tepco, government – be responsible!”
“This accident has burdened the socially weak, the farmers and fishermen,” said Mitsue Matsuda, 47, from tsunami-hit Iwate prefecture, who said she had friends living near the Fukushima plant.
“The land will stay contaminated for decades or more.”
The Health Ministry said tests on mushrooms in Iwaki, in Fukushima prefecture, had found radioactive iodine and caesium above legal limits and local authorities had asked farmers not to ship fungi, Kyodo news agency reported. Other foodstuffs have tested within official limits.
Authorities have stressed there is no immediate public health threat from seafood because fishing within a 20-kilometre radius is banned, arguing that ocean currents will quickly dilute the contaminants.
At the crippled plant, workers, troops and firefighters have pumped water into reactors whose cooling systems were knocked out by the March 11 tsunami, sparking partial meltdowns and chemical explosions.
