TerraPower
TerraPower is an American nuclear reactor design and development engineering company headquartered in Bellevue, Washington. TerraPower is developing a class of nuclear fast reactors termed traveling wave reactors (TWR). TWR places a small core of enriched fuel in the center of a much larger mass of non-fissile material, in this case depleted uranium. Neutrons from fission in the core "breeds" new fissile material in the surrounding mass, producing Plutonium-239. Over time, enough fuel is bred in the area surrounding the core that it can undergo fission, sending neutrons further into the mass and continuing the process while the original core expires. Over a period of decades, the reaction moves from the core of the reactor to the outside, thus "travelling wave". In September 2015, TerraPower signed an agreement with state-owned China National Nuclear Corporation to build a prototype 600 MWe reactor unit at Xiapu in Fujian province, China, from 2018 to 2025.

Traveling Wave Reactor
A traveling-wave reactor (TWR) is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation, in tandem with the burnup of fissile material. TWRs differ from other kinds of fast-neutron and breeder reactors in their ability to use fuel efficiently without uranium enrichment or reprocessing, instead directly using depleted uranium, natural uranium, thorium, spent fuel removed from light water reactors, or some combination of these materials. The concept is still in the development stage and no TWRs have ever been built. The name refers to the fact that fission remains confined to a boundary zone in the reactor core that slowly advances over time. TWRs could theoretically run self-sustained for decades without refueling or removing spent fuel. History Traveling-wave reactors were first proposed in the 1950s and have been studied intermittently. The concept of a reactor that could breed its own fuel inside the ...

Bill Gates
William Henry Gates III (born October 28, 1955) is an American business magnate and philanthropist. He is a co-founder of Microsoft, along with his late childhood friend Paul Allen. During his career at Microsoft, Gates held the positions of chairman, chief executive officer (CEO), president and chief software architect, while also being the largest individual shareholder until May 2014. He was a major entrepreneur of the microcomputer revolution of the 1970s and 1980s. Gates was born and raised in Seattle. In 1975, he and Allen founded Microsoft in Albuquerque, New Mexico. It became the world's largest personal computer software company. Gates led the company as chairman and CEO until stepping down as CEO in January 2000, succeeded by Steve Ballmer, but he remained chairman of the board of directors and became chief software architect. During the late 1990s, he was criticized for his business tactics, which have been considered anti-competitive. This opinion has be ...

China National Nuclear Corporation
The China National Nuclear Corporation (CNNC; ) is a state-owned enterprise founded in 1955 in Beijing. CNNC's president and vice-president are appointed by the Premier of the People's Republic of China. CNNC oversees all aspects of China's civilian and military nuclear programs. According to its own mission statement, it "is a main part of the national nuclear technology industry and a leading element of national strategic nuclear forces and nuclear energy development." CNNC is a nationwide industrial conglomerate integrating science, technology, industry, and international trade. Its headquarters are in Xicheng District, Beijing. History The Ministry of Nuclear Industry built China's first atom bomb, hydrogen bomb and nuclear submarine. It functioned as a government bureau for the national nuclear industry and reported directly to the State Council. It oversaw China's nuclear-related corporations, manufacturers, institutions, research institutes, and plants, including those ...

Fast Reactor
A fast-neutron reactor (FNR) or fast-spectrum reactor or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons (carrying energies above 1 MeV or greater, on average), as opposed to slow thermal neutrons used in thermal-neutron reactors. Such a fast reactor needs no neutron moderator, but requires fuel that is relatively rich in fissile material when compared to that required for a thermal-neutron reactor. Around 20 land based fast reactors have been built, accumulating over 400 reactor years of operation globally. The largest of this was the Superphénix Sodium cooled fast reactor in France that was designed to deliver 1,242 MWe. Fast reactors have been intensely studied since the 1950s, as they provide certain decisive advantages over the existing fleet of water cooled and water moderated reactors. These are: * More neutrons are produced when a fission occurs, resulting from the absorption of a fast neutron, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WikiProject Companies
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. F ...

Los Alamos National Laboratory
Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.The site was variously called Los Alamos Laboratory and Los Alamos Scientific Laboratory. Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together some of the world's most famous scientists, among them numerous Nobel Prize winners. The town of Los Alamos, directly north of the lab, grew extensively through this period. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles River Ventures
Charles River Ventures (CRV) is a venture capital firm focused on early-stage investments in technology. The firm was founded in 1970 to commercialize research that came out of MIT. Its name comes from the Charles River. History The firm has raised over $4.3 billion since inception across 18 funds. Upon closing of the 16th fund, the firm rebranded to CRV. Prior to that, CRV's 15th fund closed in February 2012 with $375 million of investor commitments. CRV's 14th fund raised $320 million of commitments. In 2013, it purchased a large portion of Pebble Technology for 15 million dollars and is credited as the primary reason why Pebble was sold to Fitbit in December 2016. This netted CRV nearly 40 million dollars. Among CRV's portfolio companies are Airtable, Amgen, Aveksa, Blippy, Cascade Communications, ChipCom, Ciena Corporation, ClassPass, Continental Cablevision, Crushpath, DoorDash, Drift, Earbits, Fiksu, iBasis, mabl, Netezza, OneLogin, Parametric Technology Corpo ...
