Expensive, hazardous, uncertain, radioactive cleanup in Japan

Japan Starts Nuclear Cleanup, With Little Idea of How By HIROKO TABUCHI NYT February 10, 2012 IITATE, Japan — As 500 workers in hazmat suits and respirator masks fanned out to decontaminate this village 20 miles from the ravaged Fukushima Daiichi nuclear reactors, their confusion was apparent. “Dig five centimeters or 10 centimeters deep here?” a site supervisor asked his colleagues, pointing to a patch of radioactive topsoil to be removed. He then gestured across the village square toward the community center. “Isn’t that going to be demolished? Shall we decontaminate it or not?”

A day laborer wiping down windows at an abandoned school nearby shrugged at the work crew’s haphazard approach. “We are all amateurs,” he said. “Nobody really knows how to clean up radiation.”

Nobody may really know how. But that has not deterred the Japanese government from starting to hand out an initial $13 billion in contracts meant to rehabilitate the more than 8,000-square-mile region most exposed to radioactive fallout — an area nearly as big as New Jersey. The main goal is to eventually enable the return of many of the 80,000 or more displaced people nearest the site of last March’s nuclear disaster, including the 6,500 villagers of Iitate.

It is far from clear, though, that the unproved cleanup methods will be effective.

Even more disturbing to critics of the decontamination program is the fact that the government awarded the first contracts to three giant construction companies — corporations that have no more expertise in radiation cleanup than anyone else does, but that profited hugely from Japan’s previous embrace of nuclear power.

It was these same three companies that helped build 45 of Japan’s 54 nuclear plants — including the reactor buildings and other plants at Fukushima Daiichi that could not withstand the tsunami that caused the plant’s catastrophic failure …..

Japan is undertaking a crucial task. The endeavor is meant to go far beyond the partial cleanup that followed the 1986 Chernobyl disaster in Ukraine, which left a 19-mile radius around the plant that, even a quarter-century later, remains largely off limits.

But there is little consensus on what cleanup methods might prove effective in Japan. Radioactive particles are easily carried by wind and rain, and could recontaminate towns and cities even after a cleanup crew has passed through, experts say.

“No experts yet exist in decontamination, and there is no reason why the state should pay big money to big construction companies,” said Yoichi Tao, a visiting professor in physics at Kogakuin University who is helping Iitate villagers test decontamination methods on their own. He is also monitoring the effectiveness of the energy agency’s decontamination projects.

Though big companies have won the main contracts so far, the actual cleanup — essentially a simple but tedious task of scrubbing and digging — is being carried out by numerous subcontractors and sub-subcontractors, who in turn rely on untrained casual laborers to do the dirtiest decontamination work.

This tiered structure, in which fees are siphoned off and wages dwindle each step down the ladder, follows the familiar pattern of Japan’s nuclear and construction industries…..

A similar cleanup project at the Iitate community center last fall, undertaken by the local government, was unable to reduce the radiation to safe levels.

The pilot projects led by Taisei and the other contractors have already hit snags. The government, for example, failed to anticipate communities’ reluctance to store tons of soil scraped from contaminated yards and fields.

Some critics, meanwhile, have argued that local companies and governments could perform the cleanup work for much less money, while creating local jobs.

Some Iitate villagers have enlisted the help of university experts to take matters into their own hands. Their experiments, they say, suggest that decontamination must start on the forested mountains that cover three-quarters of Iitate’s land area.

“Even if they clean up our homes, the radiation will sweep down from the mountains again and recontaminate everything,” said Muneo Kanno, a 60-year-old farmer. Like many other residents of Iitate, he stayed in the village for more than a month after the disaster, unaware that the radioactive plumes had reached Iitate….

There is no public financing for their work, which is supported by donations and the volunteer efforts of the villagers themselves. On a recent morning, about a dozen volunteers, some as old as 70, scrambled up a snowy mountainside to rake leaves into cloth sacks, wearing only regular clothes and surgical masks.

“We know the land here far better than the construction companies do,” Mr. Kanno said. “We are afraid that the money is just disappearing into thin air.”  http://www.nytimes.com/2012/02/11/business/global/after-fukushima-disaster-a-confused-effort-at-cleanup.html
