Fukushima Five Years Later: The FLEX Strategy

David Heacock

This week is the fifth anniversary of the accident at Fukushima Daiichi nuclear power plant. To mark the event, we'll be sharing observations from leaders around the nuclear energy industry all week long on how the U.S. has absorbed lessons learned from the accident to make safe nuclear plants even safer. Today's contribution comes on the industry's FLEX strategy from David Heacock, President and Chief Executive Officer of Dominion Nuclear.

The U.S. nuclear industry is well on its way toward implementing a flexible mitigation approach for responding to any event that may exceed the robust design of the nation’s nuclear power plants. This FLEX strategy, the outcome of the U.S. industry’s response to the 2011 Fukushima Daiichi accident in Japan, provides yet another layer of safety. This is in addition to the multiple back-up safety systems already available to protect the public and environment.

In effect, this strategy was demonstrated to successfully prevent damage to the reactor core at the Fukushima Daini nuclear power plant, only a short distance from its sister plant, Daiichi.

FLEX strategies provide the greatest safety benefit of all the options that could be implemented in a short period of time to further ensure public safety from extreme natural events. Each site is equipped with portable equipment capable of providing electricity and pumping water to keep the nuclear core cool and stable. This equipment can be moved easily from protective storage buildings on the site to key locations in the plant to maintain reactor cooling until a longer-term solution is put in place. Two national response centers—in Memphis, Tennessee and Phoenix—provide additional FLEX equipment and resources that can be dispatched to any U.S. nuclear station within 24 hours.

More than half of the nation’s nuclear operators have implemented the FLEX strategy and the rest are making progress towards complying with this requirement in a timely manner.

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. E…

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?
