Bill Gates: Billions for next-gen nuclear

Bill Gates plans to commit billions in a partnership between Toshiba and next-generation nuclear company TerraPower.

After releasing fireflies onto his audience at this year's TED conference, Bill Gates announced his plans to fund a viable, next-generation nuclear technology called traveling-wave reactor (TWR). And now Gates has announced an exploration between TerraPower, a TWR nuclear company he largely funds, and Toshiba Corporation, a leader in the commercial nuclear power business.
 
TWR has been theorized for decades as a cheaper and safer alternative to typical fission reactors, but until now the supercomputers required to make such technology possible were simply not affordable. It is thus no coincidence that Gates has found the perfect match for both his humanitarian and technological aims. 
 
The TWR prototype developed by TerraPower will rely upon Microsoft's supercomputing prowess and a whole lot of computer hardware — 1,024 Xeon core processors assembled on 128 blade servers offering “over 1000 times the computational ability as a desktop computer.”
 
This may be one of the first times I'm actually excited about nuclear energy. In one of my original posts called The 6 Myths of Nuclear Energy, I clearly lay out all the reasons why today's version of nuclear technology is simply not viable — too expensive, too dangerous, too water-consuming, too politically destabilizing, and on and on. There are so many reasons NOT to fund current nuclear reactor technologies even with the advancements that have been made over the last decade.
 
But TWR is a real game-changer. Instead of requiring enriched uranium, TWR can burn depleted uranium and other low-grade radioactive fuel stocks. It can also burn them for a long, long time. In TWR, a long-term reaction is created in which the waste from breeding the fuel is recombined to create more fuel inside the reactor. Theoretically, a nuclear reactor could operate for 100 years without changing the fuel rods, and the resultant waste would be much less radioactive than the waste of our modern-day reactors.
 
Here's TerraPower CEO John Gilleland explaining how it works: 
 

 
It's too early to get too exited. Even if Gates' billions combined with Toshiba's know-how does result in a full-scale industrial version of the traveling-wave reactor, it will be 10 years before one is constructed and the construction process itself will take five years. But Gates appears to be paving the way for what may be the predominant power source of the future.

Hippies originally started the anti-nuke movement, not you, so why is it your buisness, and also, as for the excess of power, all power grids do that, because the need leway to prevent brownouts, because if a power company needs to import emergency power, the other company is the only option available, so they charge enormous premiums on the level of several million per day, so they would rather have unused potential than have to spend more $$. Also, they dont use all that capacity because.... More

We've never had a shortage of electric!!

Nuclear is a waste. Take a billion dollars and subsidize individuals putting solar on their rooftops: if all roofs were solar, we'd make more than all the energy we use now, even if all our driving were plug-in cars and electric trains.

If all roofs were solar... Hmmm. I thought that too b4.
The math (based on 100 million houses x 400sq usable rooftop) = about 1,500 sq miles in. We need like 50,000 sq mi to power our cars, our homes and into the night (15% efficiency). This is just for the U.S. I'd say let's do it, but common sense says the new nuclear reactor designs would make it WAY easier than that.
Bty, MSR's create wastes that turn to lead 100 x faster than today's LWR's

Unless you live in Nevada, the sun gets covered by clouds sometimes, and even in Nevada, there is a peak demand at about 9 PM, so when the sun is gone, how does solar work
Riddle me that, Batman

Funding a new-technology reactor is not funding AIDS treatment. Even with Gates' money, this is no slam dunk. But if this works out, he just leaped from being only the former wealthiest person in the world to... well, the most successful business person in history.

Look at the scalability of solar power, wind power, tidal power, nuclear.

How much physical 'stuff' do you need to assemble to generate a wind turbine?

- typical large wind turbine that forms part of a wind farm weighs 100 tonnes and has a 100m diameter circle swept out by the blades. - it works out roughly 30kg/m^2 of turbine area.

Same question for a solar cell - the active layer of a solar cell only needs to be 5 microns thick or less, so ultimately a solar cell could be.... More

no photovoltaic materials require a tremendous amount of energy to produce and currently have quite low energy density. This means that a windy site is economically far better off installing one 1MW turbine than a giant field of solar panels to produce the equivalent amount of energy.

Solar is a great technology where sun is prevalent and wind isn't, but what Gates is funding (Traveling Wave Nuclear Reactor) makes solar look like a toy. This could make energy cheap, clean, and.... More

Bill Gates phoned my college dorm room when I was studying at The Catholic University of America in Washington, D.C. and told me I should get on the CIA Payroll while I was down there, and that I had the reputation of a saint for my chastity and morality, and that I should probably stop bad-mouthing computers and technology ( I used a typewriter) and I could work for him someday. I am the Nassau County Executive Committee Chairman of The Constitution Party, and would like to serve as.... More

If this is for real you should use the proper channels for raising cash not from commenting on articles. but I'm guessing this is a SCAM!

Asking for money is not a sin-never has been, never will be. It is not a sin to labor in my vocations-promoting clean energy, defending human rights/civil rights, the rights of the unborn,prosecuting paedophiles, and the cover-ups of the paedophiles, and I have led in providing health care by personally donating over 90 pints of whole blood and blood platelets for countless souls in need, and the word "scam" should never be used with my name at all. I have professional experience, in the.... More

Why is it that NO ONE has an answer of what to do with the dangerous nuclear waste? It typically ends up near indigenous people or other marginalized communities. Will the Gates foundation be spending billions more on trying to help alleviate the health costs form the Gates supported nuclear power plants?

the new power plant burns nuclear waste!!!!!!!!!!!!!!, and in concept could burn its own waste

It uses depleted uranium which has a half life of about 4.5 billion years. This device accelerates the decomposition process by using this already depleted fuel and depleting it more. In the end you have a waste that is almost completely depleted. This is part of the problem with the world today people open their ignorant mouths before they know anything about a subject. And to let you know I am certified and licensed by the USNRC for nuclear safety.

There's no way to dispose of isotopes that have a half-life of thousands of years!
Nuke power is stupid, and un-needed. We don't have a problem with electric!! And that's all you get with nuke power.

We have 55 gw of capacity in California, our usage never higher than 45 gw. Check the usage curve on caiso.com!!

You think nukes are stupid, but then you live on en earthquake fault in a wildfire-prone area full of coal-fired plants that pollute the air, so i wouldn't talk so loud if i were u, and nukes are cheaper that coal, more powerful, endorsed by bill gates (who is obvioulsy very smart), and used on submarines by the navy of the most powerful nation on earth, so unless the richest man on earth and the United States are both stupid, nukes are not stupid. Oh, guess what, the president also endorsed.... More
