Degelen Omega
Degelen ( kk, Дегелең) is a mountain massif in the Abai Region, Kazakhstan.''Kazakhstan National Encyclopedia'' / Ch. ed. B.O. Jakyp. — Almaty: « Kazakh encyclopedia» ZhSS, 2011. ISBN 9965-893-64-0 (T.Z.), ISBN 9965-893-19-5 Semey city, former Semipalatinsk, lies about to the ENE of the Degelen mountain area. The Balapan nuclear test site lies to the northeast. History At the time of the Kazakh SSR Degelen was part of the Semipalatinsk Test Site complex. Around hundred horizontal tunnels were bored into the mountain to carry out nuclear tests operated by the USSR armed forces. The mountain massif was the location chosen for the majority of the subcritical and supercritical tests. 215 underground nuclear explosions were carried out. In 1991, following the dissolution of the Soviet Union, the site was taken over by the government of Kazakhstan. The tunnels were closed in 1993. The abandoned electrical installations and the rails that had been used to transport the nuc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partial Nuclear Test Ban Treaty
The Partial Test Ban Treaty (PTBT) is the abbreviated name of the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, which prohibited all test detonations of nuclear weapons except for those conducted underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties. Negotiations initially focused on a comprehensive ban, but that was abandoned because of technical questions surrounding the detection of underground tests and Soviet concerns over the intrusiveness of proposed verification methods. The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ban was also seen as a means of slowing nuclear proliferati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frenchman Flat
Frenchman Flat is a hydrographic basin in the Nevada National Security Site south of Yucca Flat and north of Mercury, Nevada. The flat was used as an American nuclear test site and has a dry lake bed (Frenchman Lake) that was used as a 1950s airstrip before it was chosen after the start of the Korean War for the Nevada Proving Grounds. Nellis Air Force Base land was transferred to the Atomic Energy Commission on which Site Mercury was constructed on the flat for supporting American nuclear explosive tests. The 1951 Operation Ranger "Able" test (ground zero at UTM Coordinates 923758 on the flat) was the first continental US nuclear detonation after the 1945 Trinity test, and Frenchman Flat also had the only detonation of an American artillery-fired nuclear projectile in the 1953 Upshot-Knothole Grable test using the M65 Atomic Cannon. Area 5 Area 5 consists of of the southeastern portion of NTS, north of the town of Mercury, and includes the Area 5 Radioactive Waste Man ...

Nye County, Nevada
Nye County is a county in the U.S. state of Nevada. As of the 2020 census, the population was 51,591. Its county seat is Tonopah. At , Nye is Nevada's largest county by area and the third-largest county in the contiguous United States, behind Coconino County of Arizona and San Bernardino County of California. Nye County comprises the Pahrump Micropolitan Statistical Area, which is included in the Las Vegas-Henderson Combined Statistical Area. In 2010, Nevada's center of population was in southern Nye County, near Yucca Mountain. The Nevada Test Site and proposed Yucca Mountain nuclear waste repository are in southwestern Nye County, and are the focus of a great deal of controversy. The federal government manages 92% of the county's land. A 1987 attempt to stop the nuclear waste site resulted in the creation of Bullfrog County, Nevada, which was dissolved two years later. The county has several environmentally sensitive areas, including Ash Meadows National Wildlife Refu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevada Test And Training Range
The Nevada Test and Training Range (NTTR) is one of two military training areas at the Nellis Air Force Base Complex in Nevada and used by the United States Air Force Warfare Center at Nellis Air Force Base. The NTTR land area includes a "simulated Integrated Air Defense System", several individual ranges with 1200 targets, and 4 remote communication sites. The current NTTR area and the range's former areas have been used for aerial gunnery and bombing, for nuclear tests, as a proving ground and flight test area, for aircraft control and warning, and for Blue Flag, Green Flag, and Red Flag exercises. Geography The Nevada Test and Training Range land area is mostly Central Basin and Range ecoregion (cf. southernmost portion in the Mojave Desert), and smaller ecoregions (e.g., Tonopah Basin, Tonopah Playa, & Bald Mountain biomes) are within the area of numerous basin and range landforms of the NTTR. Landforms The NTTR is at the serpentine section of the Great Basin Divide in so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevada Test 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. Formerly known as the Nevada Proving Grounds, the site was established in 1951 for the testing of 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 could be seen from the downtown ho ...

Operation Grapple
Operation Grapple was a set of four series of British nuclear weapons tests of early atomic bombs and hydrogen bombs carried out in 1957 and 1958 at Malden Island and Kiritimati (Christmas Island) in the Gilbert and Ellice Islands in the Pacific Ocean (modern Kiribati) as part of the British hydrogen bomb programme. Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons, and the restoration of the nuclear Special Relationship with the United States in the form of the 1958 US–UK Mutual Defence Agreement. During the Second World War, Britain had a nuclear weapons project, codenamed Tube Alloys, which was merged with the American Manhattan Project in August 1943. Many of Britain's top scientists participated in the Manhattan Project. After the war, fearing that Britain would lose its great power status, the British government resumed the atomic bomb development effort, now codenamed High Expl ...

Kiritimati
Kiritimati (also known as Christmas Island) is a Pacific Ocean atoll in the northern Line Islands. It is part of the Republic of Kiribati. The name is derived from the English word "Christmas" written in Gilbertese according to its phonology, in which the combination ''ti'' is pronounced ''s'', giving kiˈrɪsmæs. Kiritimati has the greatest land area of any atoll in the world, about ; its lagoon is roughly the same size. The atoll is about in perimeter, while the lagoon shoreline extends for over . Kiritimati comprises over 70% of the total land area of Kiribati, a country encompassing 33 Pacific atolls and islands. It lies north of the equator, south of Honolulu, and from San Francisco. Kiritimati is in the world's farthest forward time zone, UTC+14, and is therefore one of the first inhabited places on Earth to experience New Year's Day. (see also Caroline Atoll, Kiribati). Although it lies east of the 180th meridian, the Republic of Kiribati realigned the Internati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Fishbowl
Operation Fishbowl was a series of high-altitude nuclear tests in 1962 that were carried out by the United States as a part of the larger ''Operation Dominic'' nuclear test program. Flight-test vehicles were designed and manufactured by Avco Corporation. Introduction The ''Operation Fishbowl'' nuclear tests were originally planned to be completed during the first half of 1962 with three tests named ''Bluegill, Starfish'' and ''Urraca''. The first test attempt was delayed until June. Planning for ''Operation Fishbowl'', as well as many other nuclear tests in the region, began rapidly in response to the sudden Soviet announcement on August 30, 1961 that they were ending a three-year moratorium on nuclear testing. The rapid planning of very complex operations necessitated many as the project progressed. All of the tests were to be launched on missiles from Johnston Island in the Pacific Ocean north of the equator. Johnston Island had already been established as a launch site ...

Operation Hardtack II
Operation Hardtack II was a series of 37 nuclear tests conducted by the United States in 1958 at the Nevada Test Site. These tests followed the ''Operation Argus'' series and preceded the ''Operation Nougat'' series. With test moratoriums on the horizon, American weapons labs rushed out many new designs. A hard deadline for testing was set at midnight (0000 hrs), October 31, 1958, as negotiations were set to start that day, and the schedule shows it, with 29 tests executed in October, four of them on the last day. One other test was cancelled because weather delays postponed it across the midnight deadline. After the conclusion of Hardtack II, the United States announced a unilateral testing moratorium, which the Soviet Union joined after two last tests on November 1 and 3. In September 1961, the Soviet Union resumed nuclear testing—this period included the test of the most powerful nuclear device ever designed, the ''Tsar Bomba'' on October 30, 1961—and the United State ...

Operation Dominic
Operation Dominic was a series of 31 nuclear test explosions with a total yield conducted in 1962 by the United States in the Pacific. This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958–1961 test moratorium. Most of these shots were conducted with free-fall bombs dropped from B-52 bomber aircraft. Twenty of these shots were to test new weapons designs; six to test weapons effects; and several shots to confirm the reliability of existing weapons. The Thor missile was also used to lift warheads into near-space to conduct high-altitude nuclear explosion tests; these shots were collectively called Operation Fishbowl. Operation Dominic occurred during a period of high Cold War tension between the United States and the Soviet Union, since the Cuban Bay of Pigs Invasion had occurred not long before. Nikita Khrushchev announced the end of a three-year moratorium on nuclear testing on 30 August 1961, and Sovi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...
