US teen designs compact nuclear reactor

LONG BEACH, California — Eighteen-year-old Taylor Wilson has designed a compact nuclear reactor that could one day burn waste from old atomic weapons to power anything from homes and factories to space colonies.

The American teen, who gained fame four years ago after designing a fusion reactor he planned to build in the garage of his family's home, shared his latest endeavor at a TED Conference in southern California on Thursday.

"It's about bringing something old, fission, into the 21st Century," Wilson said. "I think this has huge potential to change the world."

He has designed a small reactor capable of generating 50-100 megawatts of electricity, enough to power as many as 100,000 homes.

The reactor can be made assembly-line style and powered by molten radioactive material from nuclear weapons, Wilson said. The relatively small, modular reactor can be shipped sealed with enough fuel to last for 30 years.

"You can plop them down anywhere in the world and they work, buried under the ground for security reasons," he said, while detailing his design at TED.

"In the Cold War we built up this huge arsenal of nuclear weapons and we don't need them anymore," Wilson said. "It would be great if we could eat them up, and this reactor loves this stuff."

His reactors are designed to spin turbines using gas instead of steam, meaning they operate at temperatures lower than those of typical nuclear reactors and don't spew anything if there is a breach.

The fuel is in the form of molten salt, and the reactors don't need to be pressurized, according to the teenager.

"In the event of an accident, you can just drain the core into a tank under the reactor with neutron absorbers and the reaction stops," Wilson said.

"There is no inclination for the fission products to leave this reactor," he said. "In an accident, the reactor may be toast, which is sorry for the power company, but there is no problem."

Wilson, who graduated grade school in May, said he is putting off university to focus on a company he created to make Modular Fission Reactors.

He sees his competition as nations, particularly China, and the roadblocks ahead as political instead of technical.

Wilson planned to have a prototype ready in two years and a product to market in five years.

"Not only does it combat climate change, it can bring power to the developing world," Wilson said with teenage optimism.

"Imagine having a compact reactor in a rocket designed by those planning to habitat other planets. Not only would you have power for propulsion, but power once you get there."




“… New ideas are things you never thought of. These ideas will be given to you so you will have answers to the most profound questions that your societies have had since you were born. Inventions will bring clean water to every Human on the planet, cheaply and everywhere. Inventions will give you power, cheaply and everywhere. These ideas will wipe out all of the reasons you now have for pollution, and when you look back on it, you'll go, "This solution was always there. Why didn't we think of that? Why didn't we do this sooner?" Because it wasn't time and you were not ready. You hadn't planted the seeds and you were still battling the old energy, deciding whether you were going to terminate yourselves before 2012. Now you didn't…. and now you didn't.

It's funny, what you ponder about, and what your sociologists consider the "great current problems of mankind", for your new ideas will simply eliminate the very concepts of the questions just as they did in the past. Do you remember? Two hundred years ago, the predictions of sociologists said that you would run out of food, since there wasn't enough land to sustain a greater population. Then you discovered crop rotation and fertilizer. Suddenly, each plot of land could produce many times what it could before. Do you remember the predictions that you would run out of wood to heat your homes? Probably not. That was before electricity. It goes on and on.

So today's puzzles are just as quaint, as you will see. (1)How do you strengthen the power grids of your great nations so that they are not vulnerable to failure or don't require massive infrastructure improvement expenditures? Because cold is coming, and you are going to need more power. (2) What can you do about pollution? (3) What about world overpopulation? Some experts will tell you that a pandemic will be the answer; nature [Gaia] will kill off about one-third of the earth's population. The best minds of the century ponder these puzzles and tell you that you are headed for real problems. You have heard these things all your life.

Let me ask you this. (1) What if you could eliminate the power grid altogether? You can and will. (2) What if pollution-creating sources simply go away, due to new ideas and invention, and the environment starts to self-correct? (3) Overpopulation? You assume that humanity will continue to have children at an exponential rate since they are stupid and can't help themselves. This, dear ones, is a consciousness and education issue, and that is going to change. Imagine a zero growth attribute of many countries - something that will be common. Did you notice that some of your children today are actually starting to ponder if they should have any children at all? What a concept! ….”
