Radiation Leaking From Fukushima Site 18 Times Greater Than Previously Believed

fukushima

Radiation levels were being measured using devices with far-too-limited scales, the BBC reports:

Radiation levels around Japan’s Fukushima nuclear plant are 18 times higher than previously thought, Japanese authorities have warned.

Last week the plant’s operator reported radioactive water had leaked from a storage tank into the ground. It now says readings taken near the leaking tank on Saturday showed radiation was high enough to prove lethal within four hours of exposure.

The Tokyo Electric Power Company (Tepco) had originally said the radiation emitted by the leaking water was around 100 millisieverts an hour. However, the company said the equipment used to make that recording could only read measurements of up to 100 millisieverts.

The new reading will have direct implications for radiation doses received by workers who spent several days trying to stop the leak last week. Experts have said the scale of water leakage may be worse than officials have admitted.

Nuclear Reactor At Fukushima May Turned Into A Tourist Attraction

dark tourismA summer vacation spot that will give you a healthy glow? Thanks to a tip from Rhoid – Japan Today reports:

Paying visits to historic places where death and suffering occurred is known as “dark tourism.” After taking note that in 2011, or 25 years after the accident, the Chernobyl reactor site has become open to general tourism, a group of individuals in Japan is attempting to lay the groundwork for plans to make the No. 1 reactor at the stricken Fukushima Daiichi nuclear power plant a tourist spot.

The group includes author-critic Hiroki Azuma, tourism scholar Akira Ide, artist Kazuki Umezawa, media activist Daisuke Tsuda, sociologist Hiroshi Akenuma, editor Kenro Hayami and architect Ryuji Fujiwara.

Along with providing a venue to convey their own histories to future generations, the members aim for the activities to be useful in aiding in recovery of the affected areas.

Japanese Authorities Admit Fukushima Has Been Leaking Radiation Into Water For Two Years, And Cannot Be Stopped

fukushimaVia the New York Times, a reminder to always take officials with a grain of salt when they issue statements denying that the oceans and air are being poisoned:

The stricken nuclear power plant at Fukushima has probably been leaking contaminated water into the ocean for two years, ever since an earthquake and tsunami badly damaged the plant, Japan’s chief nuclear regulator said on Wednesday.

In unusually candid comments, Shunichi Tanaka, the head of the Nuclear Regulation Authority, also said that neither his staff nor the plant’s operator knew exactly where the leaks were coming from, or how to stop them.

The operator, Tokyo Electric Power, has reported spikes in the amounts of radioactive cesium, tritium and strontium detected in groundwater at the plant, adding urgency to the task of sealing any leaks. Radioactive cesium and strontium, especially, are known to raise risks of cancer in humans.

Until recently, Tokyo Electric, known as Tepco, flatly denied that any of that water was leaking into the ocean, even though various independent studies of radiation levels in the nearby ocean have suggested otherwise.

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.
