Area 10 (Nevada National Security Site)
The Nevada National Security Site (N2S2 or NNSS), known as the Nevada Test Site (NTS) until 2010, is a United States Department of Energy (DOE) reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas, Nevada, Las Vegas. Formerly known as the Nevada Proving Grounds, the site was established in 1951 for the testing of Nuclear weapon, nuclear devices. It covers approximately 1,360 square miles (3,500 km2) of desert and mountainous terrain. Nuclear weapons testing at the site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on January 27, 1951. Over the subsequent four decades, over 1,000 nuclear explosions were detonated at the site. Many of the iconic images of the nuclear era come from the site. During the 1950s, the mushroom clouds from the 100 atmospheric tests could be seen from almost away. The city of Las Vegas experienced noticeable seismic effects, and the mushroom clouds, which ...

Yucca Flat
Yucca Flat is a closed desert drainage basin, one of four major nuclear test regions within the Nevada Test Site (NTS), and is divided into nine test sections: Areas 1 through 4 and 6 through 10. Yucca Flat is located at the eastern edge of NTS, about north of Frenchman Flat, and from Las Vegas, Nevada. Yucca Flat was the site for 739 nuclear tests – nearly four of every five tests carried out at the NTS. Yucca Flat has been called "the most irradiated, nuclear-blasted spot on the face of the earth".Gerald H. Clarfield and William M. Wiecek (1984). ''Nuclear America: Military and Civilian Nuclear Power in the United States 1940–1980'', Harper & Row, New York, p. 202. In March 2009, ''TIME'' identified the 1970 Yucca Flat Baneberry Test, where 86 workers were exposed to radiation, as one of the world's worst nuclear disasters. Geology The open, sandy geology of Yucca Flat in the Tonopah Basin made for straightforward visual documentation of atmospheric nuclear tests. When ...

Peaceful Nuclear Explosions
Peaceful nuclear explosions (PNEs) are nuclear explosions conducted for non-military purposes. Proposed uses include excavation for the building of canals and harbours, electrical generation, the use of nuclear explosions to drive spacecraft, and as a form of wide-area fracking. PNEs were an area of some research from the late 1950s into the 1980s, primarily in the United States and Soviet Union. In the U.S., a series of tests were carried out under Project Plowshare. Some of the ideas considered included blasting a new Panama Canal, constructing the proposed Nicaragua Canal, the use of underground explosions to create electricity (project PACER), and a variety of mining, geological, and radionuclide studies. The largest of the excavation tests was carried out in the Sedan nuclear test in 1962, which released large amounts of radioactive gas into the air. By the late 1960s, public opposition to Plowshare was increasing, and a 1970s study of the economics of the concepts suggested t ...

Nuclear History Of The United States
Nuclear history of the United States describes the history of nuclear affairs in the United States whether civilian or military. Timeline Manhattan Project The pre- Hiroshima nuclear history of the United States began with the Manhattan Project. This Manhattan Project was the nuclear program for warfare. Even before the first nuclear weapons had been developed, scientists involved with the Manhattan Project were divided over the use of the weapon. The role of the two atomic bombings of the country in Japan's surrender and the U.S.'s ethical justification for them has been the subject of scholarly and popular debate for decades. The question of whether nations should have nuclear weapons, or test them, has been continually and nearly universally controversial.Jerry Brown and Rinaldo Brutoco (1997).

Explosion Craters
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. wikt:subsonic, Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large wikt:influx, influx of energy. Most natural explosions arise from volcano, volcanic or supernova, stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur ...

Barringer Crater
Meteor Crater, or Barringer Crater, is a meteorite impact crater about east of Flagstaff, Arizona, Flagstaff and west of Winslow, Arizona, Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo (meteorite), Canyon Diablo Meteorite, after the adjacent Cañon Diablo. Because the United States Board on Geographic Names recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor. Meteor Crater lies at an elevation of above sea level. It is about in diameter, some deep, and is surrounded by a rim that rises above the surrounding plains. The center of the crater is filled with of rubble lying above crater bedrock. One of the interesting features of the crater is its squared-off outline, believed to be caused by existing regional joint (geology), jointing (cracks) ...

Nevada ( ; ) is a state in the Western region of the United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the 7th-most extensive, the 32nd-most populous, and the 9th-least densely populated of the U.S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area, including three of the state's four largest incorporated cities. Nevada's capital is Carson City. Las Vegas is the largest city in the state. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War (the words "Battle Born" also appear on its state flag); as the "Sagebrush State", for the native plant of the same name; and as the " Sage-hen State". The name means "snowy" in Spanish, refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kali Tragus
is a species of flowering plant in the family Amaranthaceae. It is known by various common names such as prickly Russian thistle, windwitch, or common saltwort. It is widely known simply as tumbleweed because in many regions of the United States, it is the most common and most conspicuous plant species that produces tumbleweeds. Informally, it also is known as "'salsola", which was its generic name until 2007. For a brief phase during its youth, it may be grazed but afterwards becomes too spiny and woody to be edible to most wildlife and livestock (if it is not processed first). Mature specimens are often more than a meter in diameter. As its fruits mature, the diaspore of the plant dies, dries, hardens, and detach from its root. This detached anatomical part of is called a tumbleweed, which is why is colloquially called "tumbleweed" (although there are many other plant species that also produce tumbleweeds). Once mature, dry, and detached from the plant, this tumbleweed wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plowshare Program
Project Plowshare was the overall United States program for the development of techniques to use nuclear explosives for peaceful construction purposes. The program was organized in June 1957 as part of the worldwide Atoms for Peace efforts. As part of the program, 31 nuclear warheads were detonated in 27 separate tests. A similar program was carried out in the Soviet Union under the name Nuclear Explosions for the National Economy. Successful demonstrations of non-combat uses for nuclear explosives include rock blasting, stimulation of tight gas, chemical element manufacture, unlocking some of the mysteries of the R-process of stellar nucleosynthesis and probing the composition of the Earth's deep crust, creating reflection seismology vibroseis data which has helped geologists and follow-on mining company prospecting. The project's uncharacteristically large and atmospherically vented Sedan nuclear test also led geologists to determine that Barringer crater was formed as ...

Thermonuclear
Thermonuclear fusion is the process of atomic nuclei combining or “fusing” using high temperatures to drive them close enough together for this to become possible. There are two forms of thermonuclear fusion: ''uncontrolled'', in which the resulting energy is released in an uncontrolled manner, as it is in thermonuclear weapons ("hydrogen bombs") and in most stars; and ''controlled'', where the fusion reactions take place in an environment allowing some or all of the energy released to be harnessed for constructive purposes. Temperature requirements Temperature is a measure of the average kinetic energy of particles, so by heating the material it will gain energy. After reaching sufficient temperature, given by the Lawson criterion, the energy of accidental collisions within the plasma is high enough to overcome the Coulomb barrier and the particles may fuse together. In a deuterium–tritium fusion reaction, for example, the energy necessary to overcome the Coulomb barrier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury, Nevada
Mercury is a closed village in Nye County, Nevada, United States, north of U.S. Route 95 at a point northwest of Las Vegas. It is situated within the Nevada National Security Site and was constructed by the Atomic Energy Commission to house and service the staff of the test site. The specific site was known as Jackass Flats and nearby Nevada Test Site 400. Today, the site is governed by the United States Department of Energy. As part of the test site, the village is not accessible to the general public. It was named after the mercury mines which flourished in its general vicinity a century before the village itself was established. The current population is unknown. Climate According to the Köppen Climate Classification system, Mercury has a cold desert climate, abbreviated "BWk" on climate maps. The hottest temperature recorded in Mercury was on July 11, 2021, while the coldest temperature recorded was on December 22, 1990. History The village started in 1950 at ...
