Chagan (nuclear Test)
Chagan () was a Soviet underground nuclear test conducted at the Semipalatinsk Test Site on January 15, 1965. Description Chagan was the first and largest of the 124 detonations in the Nuclear Explosions for the National Economy program, designed to produce peaceful nuclear explosions (PNEs) for earth-moving purposes. The concept of using PNEs to create artificial lakes, harbors and canals was modeled after a United States program, Project Plowshare, which conducted the first peaceful nuclear explosion (the 104 kt Sedan shallow cratering test) at the Nevada Test Site in July 1962. Described as a "near clone" of the Sedan shot, Chagan's yield was the equivalent of 140 kilotons of TNT and sought to produce a large conical crater suitable for a lake. The site was a dry bed of the Chagan River (tributary of Irtysh River) at the edge of the Semipalatinsk Test Site, and was chosen such that the lip of the crater would dam the river during its high spring flow. The resultant lake h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semipalatinsk Test Site
The Semipalatinsk Test Site (Russian language, Russian: Семипалатинск-21; Semipalatinsk-21), also known as "The Polygon", was the primary testing venue for the Soviet Union's nuclear weapons. It is located on the steppe in northeast Kazakhstan (then the former Kazakh Soviet Socialist Republic, Kazakh SSR), south of the valley of the Irtysh River. The scientific buildings for the test site were located around west of the town of Semey, Semipalatinsk (later renamed Semey), near the border of East Kazakhstan Region and Pavlodar Region with most of the nuclear tests taking place at various sites further to the west and south, some as far as into Karagandy Region. The former Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many years by Soviet authorities and has only come to light since the test site closed in 1991. Ac ...

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 ...

Explosions In 1965
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. 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 influx of energy. Most natural explosions arise from volcanic or 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 outside of Earth in the universe in events su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trinitite
Trinitite, also known as atomsite or Alamogordo glass, is the glassy residue left on the desert floor after the plutonium-based Trinity nuclear bomb test on July 16, 1945, near Alamogordo, New Mexico. The glass is primarily composed of arkosic sand composed of quartz grains and feldspar (both microcline and smaller amount of plagioclase with small amount of calcite, hornblende and augite in a matrix of sandy clay) that was melted by the atomic blast. It was first academically described in ''American Mineralogist'' in 1948. It is usually a light green, although red trinitite was also found in one section of the blast site,G.

Alamogordo, New Mexico
Alamogordo () is the seat of Otero County, New Mexico, United States. A city in the Tularosa Basin of the Chihuahuan Desert, it is bordered on the east by the Sacramento Mountains and to the west by Holloman Air Force Base. The population was 31,358 as of the 2020 census. Alamogordo is known for its connection with the 1945 Trinity test, which was the first ever explosion of an atomic bomb. Humans have lived in the Alamogordo area for at least 11,000 years. The present settlement, established in 1898 to support the construction of the El Paso and Northeastern Railroad, is an early example of a planned community. The city was incorporated in 1912. Tourism became an important economic factor with the creation of White Sands National Monument in 1933, which is still one of the biggest attractions of the city today. During the 1950s–60s, Alamogordo was an unofficial center for research on pilot safety and the developing United States' space program. Alamogordo is a ch ...

Trinity Site
Trinity was the code name of the first detonation of a nuclear weapon. It was conducted by the United States Army at 5:29 a.m. on July 16, 1945, as part of the Manhattan Project. The test was conducted in the Jornada del Muerto desert about southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range, now part of White Sands Missile Range. The only structures originally in the vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. A base camp was constructed, and there were 425 people present on the weekend of the test. The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne. The test was of an implosion-design plutonium device, informally nicknamed "The Gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945.

Radioactive
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay ( ), beta decay ( ), and gamma decay ( ), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell resulting in emission of discrete X-rays from the transitions. A common example is iodine-125 commonly used in medical settings. Radioactive decay is a stochastic (i.e. random) process ...

Ashchysu
The Ashchysu ( kk, Ащысу) is a river in the Abai Region, Kazakhstan and a tributary of the Shagan (Irtysh), Shagan, of the Irtysh basin. The river is long and the area of its basin is .Google Earth Geography The Ashchysu has its sources in the northeastern slopes of the Chingiztau, a range of the eastern sector of the Kazakh Uplands, about northwest of the city of Ayagoz. It heads initially westwards, then it bends southwestwards and passes Ushbiik, then, in its lower course it bends again and heads roughly northwestwards. Finally it meets the right bank of the Shagan to the southwest of Semey, former Semipalatinsk, city. The confluence is located on the Balapan field of the Semipalatinsk Test Site complex. A lake was formed as a result of an experimental nuclear explosion to create a reservoir in January 1965. The Ashchysu is fed mainly by snow and in the summer it often dries up.

Lake Chagan
Lake Chagan (russian: Чаган) or Lake Shagan ( kk, Шаған, ''Şağan''), also known as Lake Balapan, is a lake in Kazakhstan created by the Chagan nuclear test on January 15, 1965, which was conducted as part of the Soviet Union Nuclear Explosions for the National Economy program. A 140 kiloton device was placed in a hole in the dry bed at the confluence of the Shagan and Ashchysu rivers. The blast created a crater across and deep with a lip height of ; it is often referred to as "Atomic Lake" ( kk, Атом көлі). The lake's water comes from the Shagan River, a tributary of the Irtysh River. The crater lake's volume is approximately . To the south, the rim of the crater holds back the waters of a second reservoir. Locals fish in the lake, despite warnings by authorities that it is hazardous.
