Experts: The Technology Needed To Clean Up Fukushima Doesn’t Yet Exist

One and a half years later, the consensus seems to be that the site of the Fukushima nuclear accident cannot be cleaned up or contained until future generations invent the technology to do so, Washington’s Blog notes:

World-renowned physicist Michio Kaku said recently: “It will take years to invent a new generation of robots able to withstand the radiation.” The world leader in decommissioning nuclear reactors, and one of the main contractors hired to clean up Fukushima – EnergySolutions – made a similar point in May:

Concerning the extraction of fuel debris [at Fukushima], “There is no technology which may be directly applied,” said [top EnergySolutions executive] Morant.

A top American government nuclear expert – William D. Magwood – told the U.S. Senate Committee on Environment and Public Works:

There will need to be new technologies and new methodologies created to be able to enable them to clean the site up and some of these technologies don’t exist yet, so there’s a long way to go with that…There’s a long, long way to go.

Japan To Abandon Nuclear Power By 2030s

The future isn’t always what we think it is, via Reuters:

Japan’s government said it intends to stop using nuclear power by the 2030s, marking a major shift from policy goals set before last year’s Fukushima disaster that sought to increase the share of atomic energy to more than half of electricity supply.

Japan joins countries such as Germany and Switzerland in turning away from nuclear power after last year’s earthquake unleashed a tsunami that swamped the Fukushima Daiichi plant, causing the worst nuclear crisis since Chernobyl in 1986. Japan was the third-biggest user of atomic energy before the disaster.

“This is a strategy to create a new future,” a policy statement said, after key ministers finalized the decision on Friday. “It is not pie in the sky. It is a practical strategy.”

Japanese Engineers Plug Fukushima Leak

This sounds familiar, did they get advice from BP? The Guardian reports:

Engineers battling to contain the crisis at Japan‘s Fukushima nuclear power plant appeared to have turned an important corner last night after they stopped highly radioactive water from leaking into the ocean from one of the facility’s crippled reactors.

Workers struggling to halt the leaks successfully used a mixture of sawdust, newspaper, concrete and a type of liquid glass to stem the flow of contaminated water near a seaside pit, said the plant’s owner, Tokyo Electric Power Co (Tepco).

Earlier efforts involving cement, an absorbent polymer and rags were unsuccessful in plugging the leak, which was discovered on Saturday, while radiation of more than 7.5 million times the legal limit for seawater was found just off the earthquake-hit plant.

In a sign of Tepco’s desperation, it breached its own regulations on Monday by beginning an intentional discharge of 11,500 tonnes of less contaminated water into the Pacific to make space for the highly radioactive liquid that was seeping out in an uncontrolled manner.
