In order to further improve on the current generation of reactors, TerraPower has developed the Traveling Wave Reactor (TWR), a near-term deployable and truly sustainable energy solution that is globally scalable for the indefinite future. The waves that breed and deeply burn fissile nuclides in-situ travel relative to the fuel and provide the possibility for very long core life (∼60 years) plus additional characteristics not achieved in typical fast reactor designs. nuclear concepts and products, including the Traveling Wave Reactor and industrial and human health applications. Compare, for instance, the statement in Ellis et al. Only one source of carbon-free electricity is economic, reliable 24/7, and proven to work on a large scale: nuclear power. 7 • Actinides stay in core, daughter core, or polishing system • Actinides always mixed with lanthanides • No ongoing enrichment • Exportable / Strong non-proliferation traits • Reduced water use • … One of them is a traveling wave reactor (TWR). ... Gilleland's aim is to run a nuclear reactor on what is now waste. • Our vision is to be a world leader in new nuclear technologies that bring the world sustainable, affordable, and safe energy and create high benefit products. It's gone through several incarnations over the years. This misplaced emphasis on the theoretical ability of breeder reactors to stretch the uranium resource greatly has historically led to messianic pronouncements and prom-ises. CASE STUDY OF TRAVELLING WAVE REACTOR (TWR) AND ITS FUTURE IMPACT PHYTRA3 – The Third International Conference on Physics and Technology of Reactors and … Other, unforeseen problems could also arise. By Matt Wald Enric traveling wave reactor Follow Us We are first in your inbox with the most important news in the industry―keeping you smarter and one-step ahead in this ever-changing and competitive market. a traveling-wave reactor requires very little enriched uranium, reducing the risk of weapons proliferation. The wave in the name comes from the wave of use coming from the core of the reactor outwards. The traveling wave reactor (TWR) is the brain child of Edward Teller and Lowell Wood, both famous veterans of US nuclear weapons development. TerraPower, meanwhile, decided in 2015 to develop a much larger molten salt device, the Molten Chloride Fast Reactor, as a complement to the company’s ongoing work on its sodium-cooled Traveling Wave Reactor. It works with spent fuel, breeding it into plutonium then using that. The "traveling wave reactor," first conceived in 1958, has been intensively investigated only since about 2006. When heavy atoms split and release energy, the two smaller atoms remaining (called fission products) are often left with some extra energy to give off.This energy is released over a period of time (the longest-lived waste lasting 100,000+ years) in the form of energetic particles called radiation.The high radiation is hazardous and must be kept isolated from the biosphere. ANS Nuclear Cafe. Bill Gates on Nuclear Energy and TerraPower. Teller and Wood published their original TWR proposal in 1995. The startup is exploring a molten chloride reactor concept, but says it remains committed to traveling wave reactors. A major hidden cost of today’s nuclear power is the waste it produces. Microsoft founder and extraordinary philanthropist Bill Gates is also a nuclear energy enthusiast. A traveling wave reactor's core, which TerraPower calls the technology’s “true innovation,” uses a mixture of U-235 and depleted uranium, according to the company's website. TerraPower Quietly Explores New Nuclear Reactor Strategy. The traveling wave reactor (TWR) is similar to a breeder reactor which purports to be an improvement over existing designs. TerraPower has chosen traveling wave reactors (TWRs) as its primary technology. TerraPower is developing a line of reactors that use a molten-chloride coolant, drawing on a decades-old, but still unused, invention to lower costs and reduce waste. Breeding converts incoming subcritical reload fuel into new critical fuel, allowing a breed-burn wave to propagate. FAST TRAVELING-WAVE REACTOR OF THE CHANNEL TYPE Vitaliy D. Rusov 1, Victor A. Tarasov , Volodymyr N. Vashchenko2, Sergei A. Chernezhenko 1, Andrei A. Kakaev , Oksana I. Pantak 1Department of Theoretical and Experimental Nuclear Physics, Odessa National Polytechnic University, Odessa, Ukraine 2State Ecological Academy for Postgraduate Education, Kiev, Ukraine A TWR doesn’t rely exclusively on enriched uranium, which is expensive to acquire and the waste is problematic to store with a half-life of almost 4.5 billion years. The concept works on the basis that breed-burn waves and the fuel move relative to one another. Waste Management ; Research & Applications ... traveling wave reactor. (CURRENTS) by "E"; Environmental issues Global temperature changes Greenhouse gases Nuclear energy Environmental aspects Production management Nuclear facilities Nuclear reactors January 10, 2013, 2:59PM | ANS Nuclear Cafe. The Molten Chloride Fast Reactor meets TerraPower’s vision for advanced nuclear power . Free Online Library: Seeking an energy miracle: the traveling wave reactor runs on nuclear waste - at least in theory. The traveling wave reactor (TWR) is a once-through reactor that uses in situ breeding to greatly reduce the need for enrichment and reprocessing. The traveling wave reactor currently exists only in TerraPower’s computers, but plans are underway to build a real world test version of the reactor. Traveling Wave Reactors: Sodium-cooled Gold at the End of a Nuclear Rainbow? TerraPower uses a “traveling wave reactor design,” which is technology that has been researched since the 1990’s, ... TerraPower’s reactor largely uses waste byproduct of that enrichment process, or waste uranium. The major benefit of such reactors is high fuel utilization in a manner that does not require nuclear reprocessing and could eventually eliminate the need to enrich uranium. These advantages generally relate to the fueling characteristics of TWRs; as noted above, TWRs meet the majority of their fueling requirements with waste uranium and only marginally require enriched uranium. Thus, the Travelling Wave Reactor would have the potential to use less nuclear fuel and produce less nuclear waste than the light water reactors that dominate today's nuclear fleet," he said. March/April 2009 TR10: Traveling-Wave Reactor A new reactor design could make nuclear power safer and cheaper, says John Gilleland. TerraPower’s traveling wave reactor (TWR) technology will help with a perceived problem highlighted by critics of nuclear power: nuclear waste. In this clip, Bill Gates explains a unique and earth-saving type of nuclear reactor that's in the works. Go to Article. [3] The reason traveling wave reactors were never used, even though the technology has been know for half a century, is that they produce no waste that is useful to making nuclear weapons. Teller is popularly known as the “father of the hydrogen bomb.” Both Teller and Lowell Wood played key roles in the Strategic Defense Initiative. The traveling wave reactor. Moreover, power production efficiencies could end up far lower than what their simulations suggest. The traveling wave reactor (TWR) is a once-through reactor that uses in situ breeding to greatly reduce the need for enrichment and reprocessing. http://ThoriumRemix.com/ Bill Gate's Travelling Wave reactor is the most ambitious reactor ever proposed for consuming solid uranium fuel. There's no guarantee that TerraPower's traveling-wave reactor will work in practice. Traveling wave reactor. Traveling-wave reactor (TWR) technology, being developed by TerraPower, LLC, represents a potential solution to these limitations by offering a nuclear energy resource which is truly sustainable at full global scale for the indefinite future and is deployable in the near-term. Mitch Beedie profiles TerraPower’s Traveling Wave reactor to find out whether the next generation of nuclear reactors could run by extracting the energy left over in the spoils of the present nuclear generation. Traveling Wave Reactor Advantages TWR technology has several economic, environmental, and political advantages when compared to other nuclear reactor technologies. Breeding converts incoming subcritical reload fuel into new critical fuel, allowing a breed-burn wave to propagate. Storing nuclear waste is a major challenge but could a new breed of reactor solve this? In a traveling wave reactor, a small amount of uranium 235 is used to start up the reactor. Its system of liquid sodium cooling has been attempted before with little success. Share Article. This long core life allows for significantly higher fuel utilization, up to about 30 times greater than light water reactors (LWRs). That is only reason why all nuclear power nations wanted the more dangerous reactors that … 2 The concept works on the basis that breed-burn waves and the fuel move relative to one another. The company recently got a giant boost from an investor by the name of Bill Gates who is interested in climate change and energy alternatives and who was intrigued by the idea of turning waste into fuel.
