Shagan (lake, Abai Region)
Shagan () or Chagan () is a lake in Zhanasemey District, Abai Region, Kazakhstan.Google Earth Formed by a nuclear test explosion in 1965, it is part of the Balapan complex, one of the main tourist attractions of the Semipalatinsk Test Site. Geography The lake lies to the south of the Irtysh and about to the southwest of Semey, formerly Semipalatinsk. The lake lies to the north of the confluence of the Shagan river, of the Irtysh basin, and its tributary the north-flowing Ashchysu. The Shagan river was channeled to fill the newly created crater until 1965. A few years later, a dam was built on the left bank of the river to control the water level in the reservoir that formed to the south. The reservoir still exists today, unchanged since the explosion. It is used to provide water for local cattle. History The lake was formed in the area known as the Balapan Complex by the Chagan nuclear test on January 15, 1965, which was conducted as part of the Soviet Union Nuclear Expl ...

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 Hydraulic fracturing, 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), 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Lakes Of Kazakhstan
Artificiality (the state of being artificial, anthropogenic, or man-made) is the state of being the product of intentional human manufacture, rather than occurring naturally through processes not involving or requiring human activity. Connotations Artificiality often carries with it the implication of being false, counterfeit, or deceptive. The philosopher Aristotle wrote in his ''Rhetoric'': However, artificiality does not necessarily have a negative connotation, as it may also reflect the ability of humans to replicate forms or functions arising in nature, as with an artificial heart or artificial intelligence. Political scientist and artificial intelligence expert Herbert A. Simon observes that "some artificial things are imitations of things in nature, and the imitation may use either the same basic materials as those in the natural object or quite different materials.Herbert A. Simon, ''The Sciences of the Artificial'' (1996), p. 4. Simon distinguishes between the artific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Crater Lake
A volcanic crater lake is a lake in a volcanic crater, crater that was formed by explosive eruption, explosive activity or a caldera, collapse during a types of volcanic eruptions, volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the Rim (craters), crater rim, is filled by water. The water may come from Precipitation (meteorology), precipitation, groundwater circulation (often Hot Spring, hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Karachay
Lake Karachay (), sometimes spelled Karachai or Karachaj, was a small lake in the southern Ural Mountains in central Russia. Starting in 1951, the Soviet Union used Karachay as a dumping site for radioactive waste from Mayak, the nearby nuclear waste storage and reprocessing facility, located near the town of Ozyorsk (then called Chelyabinsk-40). Today the lake is completely infilled, acting as "a near-surface permanent and dry nuclear waste storage facility." The radioactivity of the lake is comparable to the Chernobyl disaster, the worst nuclear accident of all time. Background The name '' karachay'' means "black water" or "black creek" in several Northwestern Turkic languages, including Tatar. Built in total secrecy between 1946 and 1948, the Mayak plant was the first reactor used to create plutonium for the Soviet atomic bomb project. In accordance with Stalinist procedure and supervised by NKVD Chief Lavrenti Beria, it was the utmost priority to produce enough weap ...

Pechora–Kama Canal
The Pechora–Kama Canal (), or sometimes the Kama–Pechora Canal, was a proposed canal intended to link the basin of the Pechora River in the north of European Russia with the basin of the Kama, a tributary of the Volga. Completion of this project would integrate the Pechora into the system of waterways of European Russia, centered on the Volga – something that was of importance before the advent of railways, or before the first railway reached the Pechora in the 1940s. Later the project was proposed mostly to transfer Pechora's water to the Volga and further on to the Caspian Sea. 19th century proposals In the 19th century, communication between the Kama and the Pechora was conducted mostly over a 40-km portage road between Cherdyn and Yaksha. There was also an option to use very small boats that could go up the uppermost reaches of Kama and Pechora tributaries, and cart the goods over the 4 km portage remaining. Poor river and road conditions made transportation into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedan (nuclear Test)
Storax Sedan was a shallow underground nuclear test conducted in Area 10 of Yucca Flat at the Nevada National Security Site on July 6, 1962, as part of Operation Plowshare, a program to investigate the use of nuclear weapons for mining, cratering, and other civilian purposes. The radioactive fallout from the test contaminated more US residents than any other nuclear test. The Sedan Crater is the largest human-made crater in the United States and is listed on the National Register of Historic Places. Effects Sedan was a thermonuclear device with a fission yield less than 30% and a fusion yield about 70%.Information sign at the crater: ''United States Nuclear Tests''; July 1945 through September 1992, DOE/NV--209-REV 15 December 2000, p. xv. According to Carey Sublette, the design of the Sedan device was similar to that used in the Bluestone and Swanee tests of Operation Dominic conducted days and months prior to Sedan respectively, and was therefore not unlike the W56 high yield ...

Radionuclide
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess numbers of either neutrons or protons, giving it excess nuclear energy, and making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle (alpha particle or beta particle) from the nucleus. During those processes, the radionuclide is said to undergo radioactive decay. These emissions are considered ionizing radiation because they are energetic enough to liberate an electron from another atom. The radioactive decay can produce a stable nuclide or will sometimes produce a new unstable radionuclide which may undergo further decay. Radioactive decay is a random process at the level of single atoms: it is impossible to predict when one particular atom will decay. However, for a collection of atoms of a single nu ...
