The Next Wave


Traveling Wave ReactorBill Gates and Nathan Myhrvold, two leaders in the local tech community, are
putting millions of their money behind a technology that could solve our energy
problems while offering a solution to the nagging issue of how to handle
nuclear waste.

The technology is being developed by TerraPower, a spinoff
of Myhrvold’s Bellevue-based invention company Intellectual Ventures. The
company is teaming up with Toshiba for initial development work.

TerraPower has invented a new kind of nuclear power plant
called a traveling-wave reactor. Currently, nuclear reactors use enriched
uranium (U-235), an isotope that accounts for roughly 1 percent of naturally
occurring uranium, to generate electricity. After the U-235 is separated out
for fuel in the enrichment process, the leftover material is U-238, or depleted
uranium, which typically gets sealed in waste containers near enrichment

Unlike the conventional nuclear reactor, a traveling-wave
reactor uses only a small amount of enriched uranium, and most of its core is
comprised of depleted uranium.

“If you look globally at how much uranium is readily
accessible,” TerraPower CEO John Gilleland says, “you can supply everybody on
the planet with a U.S. standard of living for many hundreds of years, and some
estimate thousands.”

The development comes at a time of renewed interest in
nuclear energy in the U.S. In February the Obama administration approved an $8
billion loan guarantee for new nuclear reactors. Since nuclear energy does not
produce carbon dioxide, it is considered a way of cutting greenhouse gases.
However, there are still concerns about weapons proliferation, possible
accidents and the perennial issue of safely disposing of waste, including the
leftovers from World War II on the Hanford Nuclear Reservation, which Gilleland
calls “nuclear junk,” useless even as fuel for a traveling-wave reactor.

 TerraPower is
currently researching materials for core construction. Gilleland says he hopes
to see the first traveling-wave reactor built by 2020, and to see commercial
reactors built later that decade.

Community Impact Awards to Honor Harriet Bullitt

Community Impact Awards to Honor Harriet Bullitt

Celebrating a lifetime of giving back to the arts and the environment.

Philanthropist Harriet Bullitt will receive the Lifetime Achievement honor at this year's Community Impact Awards presented by Seattle Business magazine on October 26 at the Museum of History & Industry. 

A longtime supporter of the arts and environmental conservation in the Pacific Northwest, Bullitt has created a legacy of achievements throughout the state of Washington. In 1989, she and her sister, the late Priscilla “Patsy” Bullitt Collins, inherited ownership of King Broadcasting Company, which their mother Dorothy Bullitt had founded in the 1940s. Harriet founded Pacific Search magazine in 1966; it later became Pacific Northwest magazine and was folded into Seattle magazine in 1994. Her family foundation’s Bullitt Center in Seattle is designed to be the “greenest” building in the world. The Snowy Owl Theater, a performance center near Leavenworth, is the centerpiece of the Sleeping Lady Mountain Resort, a retreat created by Bullitt in 1995 from an old Catholic Youth Organization summer camp.

Bullitt also founded the Icicle Fund, a charitable foundation supporting the arts and environmental protection in the upper Wenatchee Valley. And she has served on many boards, including those of the Pacific Science Center, The Nature Conservancy, Reed College and the National Audubon Society. She is vice chair of the Bullitt Foundation board of trustees.

She will join 19 other organizations and individuals being honored for the measurable impacts they have on their communities. This year's Community Impact Awards finalists are, Bellevue College/Year Up, Columbia Bank, Evrnu, FareStart, Glassybaby, Itek Energy, Kinzer Partners, McKinstry, Millionair Club, Optimum Energy, Rice Fergus Miller, Savers/Vallue Village, Skanska USA, Sleep Train, Sleeping Lady Mountain Resort, Theo Chocolate, Tree Top Inc. and Wellspring Family Services.

Tickets are on sale for the Community Impact Awards Gala at MOHAI. For more information, contact Miranda Scheitzach at
