Pensioners to Aid Nuclear Plant Clean-Up on Worker Shortage - Bloomberg

Yasuteru Yamada, a 72-year-old former anti-nuclear activist, will lead a band of pensioners to the Fukushima Dai-Ichi plant early next month to help clean up the site of Japan's worst atomic disaster since World War II.

Yamada, a retired Sumitomo Metal Industries Ltd. (5405) plant engineer, is waiting for Tokyo Electric Power Co. to allow his volunteer "Skilled Veterans Corps" to carry out preliminary inspections at the plant after the government welcomed the move.

Almost four months after the March 11 earthquake and tsunami triggered the crisis by damaging the Dai-Ichi plant, 3,514 workers involved in the clean-up have been exposed to radiation, including nine whose readings breached the annual limit of 250 millisieverts for a nuclear plant worker. Tepco said it had 1,044 workers at the plant as of June 19, about half the number a month earlier.

"I'm not on a suicide mission," said Yamada, a 1962 graduate of Tokyo University. "I am going to try my best to protect myself and come back alive."

Tepco is struggling to hire workers at the crippled plant that has spewed radiation across at least 600 square kilometers (230 square miles) in northeastern Japan. The Tokyo-based company, which has about 3,100 employees in its nuclear division, is considering ways to make the best use of its workers, said Ai Tanaka, a company spokeswoman, without elaborating.

Five-Member Team

"People who are willing to sacrifice their daily lives to help the nation resolve these problems are invaluable," Goshi Hosono, special advisor to Prime Minister Naoto Kan, said in a news briefing in Tokyo today. "First we'll have to check on their health status, as people at an advanced age working in that kind of environment could fall ill."

Yamada will be part of a five-member team comprised of former Toshiba Corp. (6502) and Chiyoda Corp. (6366) engineers who will survey damage inside the Fukushima plant, he said. More than 200 volunteers, including former nuclear workers, have signed up for the Skilled Veteran Corps, according to its website.

Banri Kaieda, the Minister of Economy, Trade and Industry, verbally supported the proposal after he met with Yamada earlier this month, according to the former engineer.

The veterans will work for free alongside existing Tepco workers at Fukushima in clean-up operations, Yamada said. The government may help subsidize accommodation, meal and transportation costs, he said.

Left-Wing Activists

Yamada was about six years old and living in Seoul when the atomic bombs devastated Hiroshima and Nagasaki, he said. During his days at Tokyo University, Yamada got involved with left-wing activists who demonstrated against nuclear weapons.

Members of the group reunited at its 50th anniversary last year, and Yamada used some of those renewed contacts to telephone and e-mail more than 2,000 of his friends and acquaintances to join his organization, he said.

Tepco is in the process of decontaminating about 105 million liters (28 million gallons) of radioactive water accumulated in the basements of the Fukushima plant. The company had doused reactors with tens of millions of liters of water to prevent fuel rods from overheating after the quake and tsunami knocked out power and backup generators.

The efforts have been marred by setbacks. In the past week, Tepco halted tests on a water decontamination system twice after problems with a pump. The stoppages won't delay plans to achieve stable cooling of the three damaged reactors by mid- July, Junichi Matsumoto, a Tepco general manager, said on June 21.

'Nuclear-Plant Workers'

"The shortage of nuclear-plant workers will be more severe if it takes more time to decontaminate and decommission the Fukushima Dai-Ichi reactors," said Tetsuo Ito, head of the Atomic Energy Research Institute at Kinki University in western Japan. "Using the senior engineers may be a good idea, but the working environment must be really tough."

Tepco plans to buy 500 additional cooling vests to wear under protective gear for plant workers to supplement 120 vests, said Tanaka, the Tepco spokeswoman.

On at least two occasions, radiation levels at Dai-Ichi reached 1 sievert an hour. Thirty minutes of exposure to that dose would trigger nausea. Contamination for four hours might lead to death within four months, according to the U.S. Environmental Protection Agency. Prolonged exposure to radiation in the air, ground and food can cause leukemia and other cancers, according to the London-based World Nuclear Association.

'Not a Kamikaze'

One Tepco worker in his 30s may have been exposed to 678.1 millisieverts of radiation after he was involved in a reactor operation on March 11, spokesman Naoki Tsunoda said. The man has since been reassigned to a clerical job at the nearby Fukushima Dai-Ni plant, Tsunoda said.

Yamada and his fellow pensioners said they're aware of the risks of entering the nuclear station.

"I am mentally prepared for death, but I'm not a kamikaze," Yamada said, referring to the Japanese soldiers who carried out suicide attacks during World War II. "The kamikaze were making irrational, obligatory self-sacrifices. What I'm doing is self-motivated and rational."
