Japan Sees Future Business In Fukushima Cleanup

(Continued)

Tentatively called the Decommissioning Company, it is overseen by the government’s economic ministry and could evolve into a decommissioning organization for other plants at home and abroad. Academics, construction giants, electronics makers and risk management firms are rushing to get on the bus.

Japan also created the government-funded International Research Institute for Nuclear Decommissioning, or IRID, last year. It brings together nuclear plant operators, construction companies and organizations of nuclear experts to promote research and development of nuclear decommissioning technologies, as well as cooperation between international and domestic organizations.

IRID has received 780 proposals for funding from around the world for ideas and technologies related to the treatment and management of contaminated water, as well as 220 others about retrieving the three melted cores.

Japanese companies including Toshiba Corp., Mitsubishi Heavy Industries and Hitachi have been developing robots that can monitor radiation, decontaminate, remove contaminated debris or repair damage, and some of them have been mobilized at the plant.

Standard decommissioning has been largely carried out by human workers. IRID Managing Director Kazuhiro Suzuki said the robotics technologies being developed to probe and remove Fukushima’s melted fuel could benefit ordinary decommissioning, not just severely damaged reactors.

“Decommissioning of aging reactors is an imminent task that all nuclear plant operators face,” he said.

Use of robotics and other advanced technologies not only helps to reduce worker radiation exposure but also could make a cleanup faster and cheaper, said Barrett, the Three Mile Island expert who now advises TEPCO and IRID.

Experts in Japan are eying a British model, the National Decommissioning Agency, founded in 2005 to be in charge of decommissioning and cleanup of nuclear plants and radioactive waste management.

TEPCO is decommissioning four reactor units crippled by the 2011 earthquake and tsunami, and will later scrap the remaining two that survived. Three suffered meltdowns and one was damaged by hydrogen explosions. The decommissioning of the four would take about 40 years.

The total cleanup cost for the severely damaged Fukushima reactors could be as high as 10 times a standard decommissioning that normally costs about 70 billion yen ($700 million) per reactor, Suzuki said.

Having completed decommissioning of 10 regular reactors and the Three Mile Island cleanup, the U.S. government and nuclear industry see a profitable market too.

In February, representatives of 26 American companies came to Tokyo for presentation and business talks with 50 Japanese companies during a two-day decommissioning and remediation forum, co-sponsored by the governments of Japan and the U.S.

“We can work together and do so much more,” said Austin Auger, an executive at CB&I, which worked with Toshiba to assemble one of the earliest treatment units for contaminated water at Fukushima.
