More than two years after an earthquake and tsunami
brought disaster to a nuclear plant in eastern Japan, operators Tokyo Electric
Power Co. (TEPCO) announced plans Wednesday to begin the painstaking and
dangerous process of removing fuel rods from a crippled reactor at the site.
The procedure is considered a
milestone in the estimated $50 billion cleanup of the Fukushima Daiichi nuclear
power plant. "Fuel removal really means the start of decommissioning," plant
chief Akira Ono said, according to Japan's Nikkei Shimbun.
When the tsunami swamped the
plant, located 149 miles (240 kilometers) north of Tokyo on Japan's eastern
seaboard in March 2011, it cut the power to vital cooling systems for the three
reactors in use at the time. This resulted in the second-worst nuclear accident
in history -- after Chernobyl in the former Soviet Union in 1986 -- as the
reactors melted down and leaked radioactive material into the atmosphere.

The Fukushima cleanup has been
beset by numerous problems, including the leak of 300
tons of radioactive water from a storage tank.
TEPCO will begin taking out 1,500
spent fuel units from Reactor 4 for storage in safer specially designed
containers, the company says. The reactor building exploded in the aftermath of
tsunami likely due to a build-up of hydrogen from a neighboring reactor,
according to TEPCO.
The cost of decontamination is
estimated to be ¥5 trillion (U.S.$50.7 billion) or more, Japan's
Fallout continues for Tokyo on
the Fukushima disaster. Earlier this week, China demanded an accurate assessment
of cleanup efforts.
"China follows closely the
countermeasures to be adopted by Japan. We urge the Japanese side to spare no
effort in minimizing the subsequent impact of the accident and provide timely,
comprehensive and accurate information to the international community," Wang
Min, China's deputy permanent representative to the United Nations, said Tuesday
at a meeting of the U.N. General Assembly, according to the state-run Xinhua
news agency.
