Fukushima Town to Test Waste Reduction System

November 28, 2011


  • The town of Hirono in Fukushima prefecture plans to test a system that would reduce the volume of radioactive debris requiring disposal by up to a factor of 300. The equipment would heat-treat the materials in an oxygen-free environment and use a ceramic powder to absorb radioactive materials.

Plant Status

  • Tokyo Electric Power Co. is planning to address any buildup of hydrogen inside the pressure vessels of Fukushima Daiichi reactors 1 through 3 by directly injecting nitrogen into the vessel. Nitrogen injection is expected to begin early December. Meanwhile, in order to increase the amount of steam in the vessels and decrease the relative buildup of hydrogen, TEPCO is reducing the flow rate of cooling water injection into the reactors. The temperatures within all three reactors are well below the boiling temperature, TEPCO reports.

Media Highlights

  • A pair of articles in the Japanese media analyzes the export market for Japanese nuclear components. Yomiuri Shimbun reports on Toshiba’s U.S. orders for turbine equipment for the nuclear energy facilities being built at the Vogtle site in Georgia and the V.C. Summer site in South Carolina. The Japan Atomic Industrial Forum notes that Japan Steel Works has forecast more than $640 million in orders from China and France for large forged components for nuclear power plants.
  • An article in The New York Times discusses how the post-Fukushima environment is changing national discussions on used nuclear fuel management.
  • Mainichi Daily News reports on the difficulty that Japan’s power industry is having in meeting its carbon dioxide reduction targets now that electricity production at nuclear energy facilities has dropped since the Fukushima accident. Kyodo News points out that Kansai Electric Power Co. is planning to restart an oil-fired plant that had been mothballed for 10 years.

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

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?

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.


The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.

What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…
