TEPCO to Build Iron Wall to Contain Radioactive Water

Plant Status

• Tokyo Electric Power Co. plans to build an “iron wall” between the Fukushima Daiichi nuclear energy facility and the ocean to keep radioactive water out of the sea. Thousands of 24-yard-long iron pipes will be sunk into the earth, extending to below the sea bed, to create a wall around the water intakes for reactors 1-4. Construction of the 875-yard wall is expected to begin by the end of the year and be complete in about two years.

Industry/Regulatory/Political Issues

• The Japan Agriculture, Forestry and Fisheries Ministry has been conducting experiments since May on reducing radiation levels in rice fields near Fukushima Daiichi. In one test, workers have scraped contaminated topsoil from dry paddies. In another, soil has been stirred in water-filled paddies and then removed. Both methods have reduced radiation levels to below government safety levels.

New Products

• New talking points summarize key topics from NEI’s comment letter to the U.S. Nuclear Regulatory Commission on proposed near-term actions at U.S. reactors following the Fukushima Daiichi accident. Another set of talking points discusses localized spikes of radiation in areas near the nuclear facility. More talking points address the NRC's approach toward plant seismic studies, which respond to misconstrued media reports on these studies.

Media Highlights

• Tokyo Electric Power Co. will put $30 billion into a new entity established to help the utility compensate individuals and businesses claiming damages caused by the Fukushima Daiichi accident, the Japan Economic Newswire reported. The fund also will receive $91 million from the government and $91 million from 11 other utility companies.

• Japanese citizens are debating the country’s energy future following the accident at Fukushima Daiichi. It is a dilemma for a country that lacks natural resources and has relied heavily on nuclear energy, NPR reports.

Upcoming Events

• A public Sept. 8 NRC Advisory Committee on Reactor Safeguards meeting will include a review the agency’s near-term task force report on the events at Fukushima.

• The NRC commissioners will be briefed on short-term actions recommended in its Japan task force report in a public meeting Sept. 14. The meeting will be webcast.

• The NRC commissioners will be briefed on prioritization of recommendations from its Japan task force in a public meeting Oct. 11. The briefing will be webcast.

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…
