Japan's 'throwaway' nuclear workers

A decade and a half before it blew apart in a hydrogen blast that punctuated the worst nuclear accident since Chernobyl, the No. 3 reactor at the Fukushima nuclear power plant was the scene of an earlier safety crisis.
Then, as now, a small army of transient workers was put to work to try to stem the damage at the oldest nuclear reactor run by Japan's largest utility.
At the time, workers were racing to finish an unprecedented repair to address a dangerous defect: cracks in the drum-like steel assembly known as the "shroud" surrounding the radioactive core of the reactor.
But in 1997, the effort to save the 21-year-old reactor from being scrapped at a large loss to its operator, Tokyo Electric, also included a quiet effort to skirt Japan's safety rules: foreign workers were brought in for the most dangerous jobs, a manager of the project said.
"It's not well known, but I know what happened," Kazunori Fujii, who managed part of the shroud replacement in 1997, told Reuters. "What we did would not have been allowed under Japanese safety standards."
The previously undisclosed hiring of welders from the United States and Southeast Asia underscores the way Tokyo Electric, a powerful monopoly with deep political connections in Japan, outsourced its riskiest work and developed a lax safety culture in the years leading to the Fukushima disaster, experts say.
A 9.0 earthquake on March 11 triggered a 15-meter tsunami that smashed into the seaside Fukushima Daiichi plant and set off a series of events that caused its reactors to start melting down.
Hydrogen explosions scattered debris across the complex and sent up a plume of radioactive steam that forced the evacuation of more than 80,000 residents near the plant, about 240 km (150 miles) northeast of Tokyo. Enough radioactive water to fill 40 Olympic swimming pools has also been collected at the plant and threatens to leak into the groundwater.
The repeated failures that have dogged Tokyo Electric in the three months the Fukushima plant has been in crisis have undercut confidence in the response to the disaster and dismayed outside experts, given corporate Japan's reputation for relentless organization.
Hastily hired workers were sent into the plant without radiation meters. Two splashed into radioactive water wearing street shoes because rubber boots were not available. Even now, few have been given training on radiation risks that meets international standards, according to their accounts and the evaluation of experts...
