Sequoyah Nuclear Power Plant
The Sequoyah Nuclear Plant is a nuclear power plant located on located east of Soddy-Daisy, Tennessee, and north of Chattanooga, abutting Chickamauga Lake on the Tennessee River. The facility is owned and operated by the Tennessee Valley Authority (TVA). The plant has two Westinghouse pressurized water reactors. Sequoyah units 1 & 2, as well as their sister plant at Watts Bar, both have ice condenser containment systems. In case of a large loss-of-coolant accident, steam generated by the leak is directed toward borated ice which helps condense the steam creating a lower pressure, allowing for a smaller containment building. Description Sequoyah's two units have a winter net dependable capacity of 2,440 megawatts,Securities & Exchange Commission filing.

Cherokee Syllabary
The Cherokee syllabary is a syllabary invented by Sequoyah in the late 1810s and early 1820s to write the Cherokee language. His creation of the syllabary is particularly noteworthy as he was illiterate until its creation. He first experimented with logograms, but his system later developed into the syllabary. In his system, each symbol represents a syllable rather than a single phoneme; the 85 (originally 86) characters provide a suitable method for writing Cherokee. The letters resemble characters from other scripts, such as Latin, Greek, Cyrillic, and Glagolitic, but are not used to represent the same sounds. History Early history Around 1809, impressed by the "talking leaves" of European written languages, Sequoyah began work to create a writing system for the Cherokee language. After attempting to create a character for each word, Sequoyah realized this would be too difficult and eventually created characters to represent syllables. He worked on the syllabary for tw ...

Little Tennessee River
The Little Tennessee River (known locally as the Little T) is a tributary of the Tennessee River that flows through the Blue Ridge Mountains from Georgia, into North Carolina, and then into Tennessee, in the southeastern United States. It drains portions of three national forests— Chattahoochee, Nantahala, and Cherokee— and provides the southwestern boundary of the Great Smoky Mountains National Park. Numerous dams were erected on the river in the 20th century for flood control and hydropower generation. The river flows through five major impoundments: Fontana Dam, Cheoah Dam, Calderwood Dam, Chilhowee Dam, and Tellico Dam, and one smaller impoundment, Porters Bend Dam. Course The Little Tennessee River rises in the Blue Ridge Mountains, in the Chattahoochee National Forest in northeast Georgia's Rabun County. After flowing north through the mountains past Dillard into southwestern North Carolina, it is joined by the Cullasaja River at Franklin. The riv ...

Overhill Cherokee
The Overhill Cherokee were a group of the Cherokee people located in their historic settlements in what is now the U.S. state of Tennessee in the Southeastern United States, on the western side of the Appalachian Mountains. This name was used by 18th-century European traders and explorers from British colonies along the Atlantic coast, as they had to cross the mountains to reach these settlements. Situated along the lower Little Tennessee, lower Tellico, lower Hiwassee and upper Tennessee rivers, the Overhill towns rose to prominence within the Cherokee Nation in the early 18th century. They began to standardize trade with British colonists. In the early part of the century, the Overhill towns' remote location at the far end of the Trading Path meant they were reached only by those traders and explorers adventurous enough to make the difficult journey to the interior over the mountain range. By the middle of the century, the Overhill towns were consistently courted by both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cherokee
The Cherokee (; , or ) people are one of the Indigenous peoples of the Southeastern Woodlands of the United States. Prior to the 18th century, they were concentrated in their homelands, in towns along river valleys of what is now southwestern North Carolina, southeastern Tennessee, southwestern Virginia, edges of western South Carolina, northern Georgia (U.S. state), Georgia and northeastern Alabama with hunting grounds in Kentucky, together consisting of around 40,000 square miles. The Cherokee language is part of the Iroquoian languages, Iroquoian language group. In the 19th century, James Mooney, an early American Ethnography, ethnographer, recorded one oral tradition that told of the Tribe (Native American), tribe having migrated south in ancient times from the Great Lakes region, where other Iroquoian Peoples, Iroquoian peoples have been based. However, anthropologist Thomas R. Whyte, writing in 2007, dated the split among the peoples as occurring earlier. He believes that ...

Sequoyah
Sequoyah ( ; , , or , , ; 1770 – August 1843), also known as George Gist or George Guess, was a Native American polymath and Constructed script, neographer of the Cherokee Nation. In 1821, Sequoyah completed his Cherokee syllabary, enabling reading and writing in the Cherokee language. One of the first North American Indigenous groups to gain a written language, the Cherokee Nation officially adopted the syllabary in 1825, helping to unify a forcibly divided nation with new ways of communication and a sense of independence. Within a quarter-century, the Cherokee Nation had reached a literacy rate of almost 100%, surpassing that of surrounding European Americans, European-American settlers. Sequoyah's creation of the Cherokee syllabary is among the few times in recorded history that an individual member of a pre-literate group created an original, effective writing system. It is believed to have inspired the development of 21 scripts or writing systems used in 65 languages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fusion
Nuclear fusion is a nuclear reaction, reaction in which two or more atomic nuclei combine to form a larger nuclei, nuclei/neutrons, neutron by-products. The difference in mass between the reactants and products is manifested as either the release or absorption (electromagnetic radiation), absorption of energy. This difference in mass arises as a result of the difference in nuclear binding energy between the atomic nuclei before and after the fusion reaction. Nuclear fusion is the process that powers all active stars, via many Stellar nucleosynthesis, reaction pathways. Fusion processes require an extremely large Lawson criterion, triple product of temperature, density, and confinement time. These conditions occur only in Stellar core, stellar cores, advanced Nuclear weapon design, nuclear weapons, and are approached in List of fusion experiments, fusion power experiments. A nuclear fusion process that produces atomic nuclei lighter than nickel-62 is generally exothermic, due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapons
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either nuclear fission, fission (fission or atomic bomb) or a combination of fission and nuclear fusion, fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had Nuclear weapon yield, yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 Petajoule, PJ). Apart from the blast, Effects of nuclear explosions, effects of nuclear weapons include Firestorm, firestorms, extreme Thermal radiation, heat and ionizing radiation, radioactive nuclear fallout, an Nuclear electromagnetic pulse, electromagnetic pulse, and a radar blackout. The first nuclear weapons were deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tritium
Tritium () or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.33 years. The tritium nucleus (t, sometimes called a ''triton'') contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (''protium'') contains one proton and no neutrons, and that of non-radioactive hydrogen-2 ('' deuterium'') contains one proton and one neutron. Tritium is the heaviest particle-bound isotope of hydrogen. It is one of the few nuclides with a distinct name. The use of the name hydrogen-3, though more systematic, is much less common. Naturally occurring tritium is extremely rare on Earth. The atmosphere has only trace amounts, formed by the interaction of its gases with cosmic rays. It can be produced artificially by irradiation of lithium or lithium-bearing ceramic pebbles in a nuclear reactor and is a low-abundance byproduct in normal operations of nuclear reactors. Tritium is used as the energy source in radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
