IAEA Update on Trip to Japan

image IAEA’s team of nuclear experts has a preliminary assessment available on Fukushima-Daiichi and Japan’s overall response to the accident. There are some good nuggets and takeaways from their experience. Below are a few of the team’s preliminary findings and lessons learned:

- Japan's response to the nuclear accident has been exemplary, particularly illustrated by the dedicated, determined and expert staff working under exceptional circumstances;

- Japan's long-term response, including the evacuation of the area around stricken reactors, has been impressive and well organized. A suitable and timely follow-up programme on public and worker exposures and health monitoring would be beneficial;

- The tsunami hazard for several sites was underestimated. Nuclear plant designers and operators should appropriately evaluate and protect against the risks of all natural hazards, and should periodically update those assessments and assessment methodologies;

- Nuclear regulatory systems should address extreme events adequately, including their periodic review, and should ensure that regulatory independence and clarity of roles are preserved; and

- The Japanese accident demonstrates the value of hardened on-site Emergency Response Centres with adequate provisions for handling all necessary emergency roles, including communications.

Worth noting, here’s what the more-detailed report (pdf) said in a sentence by itself on page 3:

To date no health effects have been reported in any person as a result of radiation exposure from the nuclear accident.

There are definitely some good observations from this first cut, look for their final report later this month.

The comment about "no health effects having been reported as a result of radiation exposure from the nuclear accident" makes me wonder. Wasn't there a story about two workers stepping in water in a flooded building and being rushed to a hospital? Isn't that enough to make the above statement false?

If they only meant members of the public at large they should have explicitly stated that assumption. The public really latches on to any apparent inconsistency and uses it to justify questioning everything the industry says.

I feel that the IAEA Fukushima Fact-Finding Team's report is a tad too generous in paise. I wonder whether this could partially be because Mr. Yukiya Amano, the Director General, is from Japan.

Those employees exposed to the flooded building water were "rushed" to a hospital to be checked out and examined for effects of an extremity (feet and lower leg) shallow dose overexposure. It was estimated they have have received in the range of 1-2 Sv of exposure to the skin. They were released and sent home with no apparent ill effects. Shallow dose can cause things like erythema, which looks a lot like sunburn. If you even want to count it at all, that might only be considered a very minor health effect. I just got a bit of a sunburn last week mowing the lawn. Didn't make the papers...

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.
