TEPCO Successfully Tests Cover for Fukushima Daiichi Reactor 1

October 31, 2011

Plant Status

  • Tokyo Electric Power Co. reports that pilot tests of the ventilation system associated with the cover it has installed over Fukushima Daiichi reactor 1 showed the system successfully filtered more than 90 percent of the radioactive cesium released from the reactor. TEPCO is considering installing similar covers for reactors 3 and 4, both of which were damaged by hydrogen explosions following the March 11 accident.

Industry/Regulatory/Political Issues

  • Japan’s environment ministry said it will store radioactive soil and waste for at least three years within Fukushima prefecture before it is moved out of the area for final disposal. The ministry said it hopes to build the temporary storage facilities by 2014.

Media Highlights

  • The Daily Yomiuri reports on the results of Kansai Electric’s first-stage stress test on its Ohi reactor 3 and on the uncertainties surrounding the timing for the restart of Japan’s shutdown reactors. The computer-based test found that the reactor could withstand ground motion from an earthquake nearly double the strength of the plant’s design and a tsunami four times stronger than the plant’s safety standards.
  • Newspaper reports say that both India and Vietnam continue to negotiate with Japan on importing Japanese nuclear reactor technology.

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Seeing the Light on Nuclear Energy

If you think that there is plenty of electricity, that the air is clean enough and that nuclear power is a just one among many options for meeting human needs, then you are probably over-focused on the United States or Western Europe. Even then, you’d be wrong.

That’s the idea at the heart of a new book, “Seeing the Light: The Case for Nuclear Power in the 21st Century,” by Scott L. Montgomery, a geoscientist and energy expert, and Thomas Graham Jr., a retired ambassador and arms control expert.


Billions of people live in energy poverty, they write, and even those who don’t, those who live in places where there is always an electric outlet or a light switch handy, we need to unmake the last 200 years of energy history, and move to non-carbon sources. Energy is integral to our lives but the authors cite a World Health Organization estimate that more than 6.5 million people die each year from air pollution.  In addition, they say, the global climate is heading for ruinous instability.
