Is this the future of clean energy? Source: TerraPower.
Things may be different today, but in its heyday, Microsoft was a game-changing company that forever altered the way the world interacted with computers. The creative genius and foresight of Bill Gates has paid off in a significant way: He's the wealthiest person in the world with a net worth of $76 billion, according to Forbes. While Gates still advises Microsoft, he has turned much of his attention to philanthropy through the Bill & Melinda Gates Foundation. When he's not eradicating poverty, disease, and a lack of opportunity for billions of people across the globe, Gates is solving other problems -- such as what to do with the world's growing stockpile of nuclear waste.
Questioning how to solve that problem led to the creation and funding of TerraPower, a start-up aiming to develop a Generation IV nuclear reactor that can run on a single loading of nuclear waste for 60 years and be cooled by liquid sodium. Some may argue that the nuclear industry is no place for a start-up, but engineering firm and nuclear design leader Babcock & Wilcox (NYSE: BWC ) believes otherwise. The company has agreed to provide support to TerraPower as it develops the first prototype of its innovative reactor. What does it mean for TerraPower and Babcock & Wilcox, or competing reactor designs from General Electric Company (NYSE: GE ) ? Are we on our way to a sustainable nuclear-powered future?
Opening the Gates to clean energy
Startups often bust into an industry to disrupt the status quo and upset incumbents -- and TerraPower is no different. The company's Generation IV reactor design is based on a traveling wave reactor, or TWR, which can utilize depleted uranium (U-238) -- dismissed as waste -- as fuel. Better yet, the TWR can use depleted uranium to create fuel, or breed, to sustain economic operations for decades. TerraPower is leveraging well-known fast-reactor technology already developed in France, Japan, Germany, China, Russia, and the United States; supercomputer simulations for modeling operations; and basic energy-saving principles such as using sodium as a coolant rather than water.
While the idea may seem fanciful, consider that Argonne National Laboratory built the Experimental Breeder Reactor II in the early 1960s. It successfully demonstrated that a reactor could breed its own fuel in a closed-loop system and be cooled by a liquid metal. Later work with the reactor would test alternative fuel types and materials to build a foundation for later commercial reactors. Unfortunately, the reactor was shut down in 1994 -- and no integral fast reactors were ever built.

Fast forward to 2014 and the recent announcement that Babcock & Wilcox and TerraPower are joining forces to design and deploy a 550 MWe demonstration TWR. The pair is circling 2022 for the potential start-up date, and China as the potential host nation. The prototype reactor will help prove the company's traveling wave design, key operating equipment, and materials while providing a technical and licensing basis for future TWR designs. And, of course, supply power to the grid.

After collecting enough data from operations of the 550 MWe demonstration plant and acquiring the correct licensing permits, TerraPower and partners such as Babcock & Wilcox will be able to build commercial reactors, currently designed with a 1,150 MWe capacity, around the globe. Demonstration could take years, while building a commercial reactor could take several more, which means the TWR design is over 10 years away from providing ultra-clean sustainable power. That may give General Electric -- already considering a location in the United Kingdom for its next-generation reactor -- an early edge in the race to develop and deploy Generation IV reactors.
However, it's important to remember that many designs will flourish. Given the unique advantages of the proposed TWR, it wouldn't be difficult for TerraPower and Babcok & Wilcox to find suitors if their proposed design proves to work as planned. For instance, a single fuel loading can power a reactor for its entire 60-year lifetime -- saving up to $2 billion for a power generator! Additionally, the TWR could become a platform for additional future designs, including those that utilize thorium as fuel, rather than a single reactor.
Foolish bottom line
There are still several hurdles to deploying the technology. For instance, finding materials strong enough to sustain a reaction for decades with minimal -- or no -- maintenance, depending on the location of the equipment in question. That's one of the big reasons we won't see a commercial TWR deployed for quite some time. But no matter how you look at it, the future of energy looks pretty bright thanks to companies such as TerraPower, Babcock & Wilcox, and General Electric. Would you support a nuclear-waste-powered future? Weigh in with thoughtful comments below.
It’ll be perfectly save and won’t crash just like Microsoft windows.
Nuclear power should have never been synonymous with boiling-water reactors fueled by uranium. There are so many other good choices.
They said the pilot reactor was going to be built in China, where they are also going full-out on R & D for a Thorium reactor. And they are building coal-fired power plants like crazy.
Sure, they are environmental pigs. But they also want to develop their country. And leave us behind.
The words “nuclear” and “atomic” in any application triggers an automatic rejection by the Marxist computers..
Sorry, but Gates has only slightly more technical competence than does the Algore manbearthing.
Who gives a smelly Obama what the *%#@ that crook businessman thinks?
Clearly written by someone who is reading off a power point foil.
1) All current fission reactors use U238. It needs to be enriched to 5-10% U235 to sustain critical opperation.
2) Breeders using Sodium coolant have been tried before.
The neutron flux isn’t high enough to create Pu239 in any serious quantity.
3) If we can’t get a stupid pipeline approved, the chances are zero of getting a breeder approved.
Pretty big facility just to power his house. Running lynux?
Its helpful here to know that Norway has been testing thorium for the last year. Their test results have been leaked to several countries including the USA.

Its also helpful to know that Babcox and Wilcox makes the nuclear reactors for for US submarines.
Gates’ team has recently modified their reactor so that its not a traveling wave reactor but a standing wave reactor

That may be because his team has been showing up at thorium power events.

Gates wants to have prototype developed in 10 years. Hard to say where they’ll do the prototype. Might be in china.
This confluence of events may be why China pushed forward its development time of their thorium reactor as well to 10 years out. A China official quoted in this article says: “”This is definitely a race,” said Li. China “faces fierce competition from overseas and to get there first will not be an easy task”, he said.” http://www.scmp.com/news/china/article/1452011/chinese-scientists-urged-develop-new-thorium-nuclear-reactors-2024

see my post above. I think that Gates team is drifting toward an lftr design.
I think he uses solar power to run his house. He’s off grid. The portable nukes he’s working on are designed for base load. That is, everyone using the grid.
agree but the people he hires are no slouches. He has the money to pull this off if he wants to.
That would be good for America. Hope it happens.
Sodium? isn’t that quite corrosive?
Well, it's reactive.
Water is corrosive. The only reason we don't realize how water is is because we're made of it.
To metallic sodium, water is so corrosive it's explosive.
But they've used molten sodium to make a few nuclear reactors. One of them underwent a partial meltdown at the Santa Susanna lab (near Los Angeles) in 1959.

Bill as writing assembly language on mainframes before you were probably even born. I also don’t see you trying to solve these problems.
I’ve been following Thorium design theory.
It is interesting but I’d like to see a small scale version before going full scale.
U232 side effect generation of using Thorium is a serious gamma emitter and this has not been solved.
Killing fuel processors and reactor refueling teams would be bad.
One can imagine a closed loop liquid sodium system. Pump seals, valves, drain and fill processes.
A leak is likely a fire.
I hope this works. We need alternatives to gas fired combined cycle.
