Efim P. Slavsky
Efim Pavlovich Slavsky (October 26, 1898 – November 8, 1991) was a Soviet statesman, head of the Ministry of Medium Machine Building, and three-time recipient of the Hero of Socialist Labour award. Slavsky was best known for his work cleaning up the Kyshtym disaster in 1957 and again at Chernobyl in 1986. Slavsky was in charge of the Ministry of Medium Machine Building, the agency responsible for the construction of nuclear installations in the Soviet Union. Slavsky was also one of the chief designers of the Soviet RBMK nuclear reactor. Early life Slavsky was born on October 26, 1898, in Makiivka to a peasant family in the Russian Empire. His father, Faivel Slavsky, perished at the age of 70 after which Efim became a shepherd at age 8. At age 15, Slavsky went to work in the Donbas region coal mines. In 1918, Efim joined the Red Guard before fighting with the Petliurists. After its dissolution in 1923, Slavsky took a political course and became a regiment commissar ...

A-bomb (RDS-1)
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been ...

RBMK Reactor Schematic
The RBMK (russian: реактор большой мощности канальный, РБМК; ''reaktor bolshoy moshchnosti kanalnyy'', "high-power channel-type reactor") is a class of graphite-moderated nuclear power reactor designed and built by the Soviet Union. The name refers to its design where, instead of a large steel pressure vessel surrounding the entire core, the core is surrounded by a cylindrical annular steel tank inside a concrete vault and each fuel assembly is enclosed in an individual 8 cm (inner) diameter pipe (called a "technological channel"). The channels also contain the coolant, and are surrounded by graphite. The RBMK is an early Generation II reactor and the oldest commercial reactor design still in wide operation. Certain aspects of the original RBMK reactor design, such as the large positive void coefficient, the 'positive scram effect' of the control rods and instability at low power levels, contributed to the 1986 Chernobyl disaster, in whi ...

Pripyat
Pripyat ( ; russian: При́пять), also known as Prypiat ( uk, При́пʼять, , ), is an abandoned city in northern Ukraine, located near the border with Belarus. Named after the nearby river, Pripyat, it was founded on 4 February 1970 as the ninth ''atomgrad'' (a type of closed town in the Soviet Union) to serve the nearby Chernobyl Nuclear Power Plant, which is located in the adjacent ghost city of Chernobyl. Pripyat was officially proclaimed a city in 1979 and had grown to a population of 49,360 by the time it was evacuated on the afternoon of 27 April 1986, one day after the Chernobyl disaster. Although it was located within the administrative district of Ivankiv Raion (now Vyshhorod Raion since the 2020 raion reform), the abandoned municipality now has the status of city of regional significance within the larger Kyiv Oblast, and is administered directly from the capital of Kyiv. Pripyat is also supervised by the State Emergency Service of Ukraine, which manage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Of The East Urals Radioactive Trace
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Loss-of-coolant Accident
A loss-of-coolant accident (LOCA) is a mode of failure for a nuclear reactor; if not managed effectively, the results of a LOCA could result in reactor core damage. Each nuclear plant's emergency core cooling system (ECCS) exists specifically to deal with a LOCA. Nuclear reactors generate heat internally; to remove this heat and convert it into useful electrical power, a coolant system is used. If this coolant flow is reduced, or lost altogether, the nuclear reactor's emergency shutdown system is designed to stop the fission chain reaction. However, due to radioactive decay, the nuclear fuel will continue to generate a significant amount of heat. The decay heat produced by a reactor shutdown from full power is initially equivalent to about 5 to 6% of the thermal rating of the reactor. If all of the independent cooling trains of the ECCS fail to operate as designed, this heat can increase the fuel temperature to the point of damaging the reactor. *If water is present, i ...

Plutonium
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 ( half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since ...

Kyshtym
Kyshtym (russian: Кышты́м) is a town in Chelyabinsk Oblast, Russia, located on the eastern slopes of the Southern Ural Mountains northwest of Chelyabinsk, near the town of Ozyorsk. Population: 36,000 (1970). History Kyshtym was established by the Demidovs in 1757 around two factories for production of cast iron and steel. The city emblem shows the Kyshtym Manor House, a Palladian residence of Nikita Demidov Jr. According to Herbert Hoover, a small iron industry had existed there "for one hundred and fifty years", which produced a secret process for generating sheet iron "unusually resistant to rust." The process "consisted of alternately heating the sheets and sweeping them when hot with a wet pine-bough. The effect was to create a coating of iron oxide which was rust-resistant." Baron Meller-Zakomelsky's Kyshtym estate became of interest to foreign capital, after the 1905 Russian Revolution and subsequent depression. A British consortium around Charles Leslie brou ...

Mayak Nuclear Station
The Mayak Production Association (russian: Производственное объединение «Маяк», , from 'lighthouse') is one of the biggest nuclear facilities in the Russian Federation, housing a reprocessing plant. The closest settlements are Ozyorsk to the northwest and Novogornyi to the south. Lavrentiy Beria led the Soviet atomic bomb project. He directed the construction of the Mayak Plutonium plant in the Southern Urals between 1945–48, in a great hurry and secrecy as part of the Soviet Union's atomic bomb project. Over 40,000 Gulag prisoners and POWs built the factory and the closed nuclear city of Ozersk, called at the time by its classified postal code "Forty". Five (today closed) nuclear reactors were built to produce plutonium which was refined and machined for weapons. Later the plant came to specialise in reprocessing spent nuclear fuel from nuclear reactors and plutonium from decommissioned weapons. Once production began, engineers quickl ...

Joe-1
The RDS-1 (russian: РДС-1), also known as Izdeliye 501 (device 501) and First Lightning (), was the nuclear bomb used in the Soviet Union's first nuclear weapon test. The United States assigned it the code-name Joe-1, in reference to Joseph Stalin. It was detonated on 29 August 1949 at 7:00 a.m., at the Semipalatinsk Test Site, Kazakh Soviet Socialist Republic, Kazakh SSR, after top-secret research and development as part of the Soviet atomic bomb project. Description The weapon was designed at the Kurchatov Institute, then at the time officially known as "Laboratory № 2" but designated as the "office" or "base" in internal documents, starting in April 1946. Plutonium for the bomb was produced at the industrial complex Mayak, Chelyabinsk-40. The RDS-1 nuclear weapon yield, explosive yield was 22 kilotons TNT equivalent, similar to the US Trinity (nuclear test)#The Gadget, Gadget and Fat Man bombs. At Lavrentiy Beria's insistence, the RDS-1 bomb was designed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
