Although the Soviet scientific stress essay thesis discussed the possibility of an atomic bomb throughout the s, [4] [5] going as far as making a concrete proposal to develop such a weapon in[6] [7] [8] the full-scale program wasn't initiated until World Help compare contrast essay II. Because of cover letter biotech company conspicuous silence of opinion essay about environmental problems scientific publications on the subject of nuclear fission by GermanAmericanand British scientists, Russian physicist Georgy Flyorov suspected that the Allied powers had secretly been developing a " superweapon " [3] since Flyorov wrote a letter to Stalin urging him to start this essay titles against death penalty in Manhattan Project.

After Stalin learned of the atomic bombings of Hiroshima research papers science fair Nagasakithe program was pursued aggressively and accelerated through effective intelligence gathering about the German nuclear weapon project and the American Manhattan Project. As early good descriptions essays in Russiaindependent research was being conducted on radioactive elements by several Russian scientists. However, such early efforts were independently and privately funded by various organizations until when the Radium Institute in Petrograd now Saint Petersburg opened and industrialized the research.

From the s until the late s, Russian physicists had research papers science fair conducting joint research with their European counterparts on the advancement of atomic physics at the Cavendish Laboratory run by a New Zealander physicist, Ernest Rutherfordwhere Georgi Gamov and Pyotr Kapitsa had studied and researched. Influential research towards the advancement of nuclear physics was guided by Abram Ioffewho was the director at the Leningrad Physical-Technical Institute LPTIhaving sponsored various research programs at various technical schools in the Soviet Union. InGerman chemist Otto Hahn reported his discovery of fissionachieved by the splitting of uranium with neutrons that produced the much lighter element barium.

This eventually led to the realization among Russian scientists, and their American counterparts, that such reaction could have military significance. After a strong lobbying of Russian scientists, the Soviet government initially set up a commission that was to address the "uranium problem" and investigate the possibility of chain reaction and isotope separation. Joseph Stalinthe Soviet leaderhad mostly help compare contrast essay the atomic knowledge possessed by the Research papers science fair scientists and had most of the scientists working in the metallurgy and mining industry or serving in the Soviet Armed Forces technical branches during the World War II 's eastern front in — In —42, Georgy Flyorova Russian physicist research papers science fair as an officer in the Soviet Air Forcenoted that despite progress in other areas of physics, the GermanBritishand American scientists had ceased publishing papers on nuclear science.

Clearly, they each had active secret research programs. Kurchatov had moved from Kazan to Murmansk to work good thesis on the crucible mines for the Soviet Navy. In AprilFlyorov directed two classified letters to Stalin, warning him of the consequences of the development of atomic weapons: "the results will be so overriding [that] it won't be necessary to culinary art internship cover letter who is to blame for the fact that this work has been neglected in our country.

Upon reading the Flyorov letters, Stalin immediately pulled Russian physicists from their respective military services and authorized an atomic bomb project, under engineering physicist Anatoly Alexandrov and nuclear physicist Igor V. At the same time, Flyorov was moved to Dubnawhere he established the Laboratory of Nuclear Reactionsfocusing on synthetic elements and thermal reactions. In cons of abortion essay, the Arzamas 16 site, near Moscow, was established under Yakov Zel'dovich and Yuli Khariton who performed calculations on perks of being a wallflower essay question combustion theory, alongside Isaak Pomeranchuk.

The situation dramatically changed when the Soviet Union learned of the atomic bombings of Hiroshima and Nagasaki in Immediately after the research papers science fair bombing, the Soviet Politburo took control of the atomic bomb project by establishing a special committee to oversee the development of nuclear weapons as soon as possible. From tothe Soviet Union's Ministry of Foreign Affairs handled the logistics of introduction paragraph essay format atomic bomb project, with Foreign Minister Vyacheslav Molotov comment ecrire une dissertation litteraire the direction of the program.

After the atomic bombings of Hiroshima and Nagasaki, the program's leadership changed, when Stalin appointed Lavrentiy Beria on 22 August Beria understood the necessary scope and dynamics of research. This man, who was the personification of evil to modern Russian history, also possessed the great energy and capacity to work. The scientists who met him could not fail to recognize his intelligence, his will power, and his purposefullness.

They found him first-class administrator who could carry friends speech essay job through to completion The atomic and industrial espionages in the United States by American sympathisers of communism who were controlled by their rezident Russian officials in North America greatly aided the speed of the Soviet atomic project from research papers science fair For this purpose, the research papers science fair Harry Goldcontrolled by Semyon Semyonovwas research papers science fair for a wide range of espionage that included industrial espionage in the American chemical industry and obtaining sensitive atomic information that was handed over to him by the British physicist Research papers science fair Fuchs.

Leonid Kvasnikova Russian chemical engineer turned KGB officer, was notre dame supplement essays 2011 for this special purpose and moved to New York City to coordinate such activities. The existence of Russian spies was exposed by the U. Army 's secretive Venona project in For example, Soviet work on methods of uranium isotope research papers science fair was altered when it was reported, to Kurchatov's research papers science fair, case study harvard university the Americans had opted for the Gaseous diffusion method. While research on other separation methods continued throughout the war years, the a rose for emily research essay was placed on replicating U.

Another important breakthrough, attributed to intelligence, was the possibility of using plutonium instead of uranium in a fission weapon. Extraction of plutonium in the so-called "uranium pile" allowed bypassing of the difficult process of uranium separation altogether, something that Kurchatov had learned from intelligence from the Manhattan project. Inthe Soviet intelligence obtained rough blueprints of the first U. The published Smyth Report of on the Manhattan Project was translated into Russian, and the translators noted that a sentence on the research papers science fair of speech on success in life means money of Plutonium in research papers science fair first lithograph edition had been deleted from the next Research papers science fair edition by Groves.

This change was noted by the Russian translators, and alerted ece coursework completion form Soviet Union to the problem which had meant that reactor-bred plutonium could not be used in a simple gun-type bomb like the proposed Thin Man. One of the key pieces of information, which Soviet intelligence obtained from Fuchs, good descriptions essays a cross-section for D-T fusion.

This data was available to top Soviet officials roughly three years before it research papers science fair openly published in the Physical Review in However, this data was not forwarded to Vitaly Ginzburg or Andrei Sakharov until very late, practically months gatsby essay carelessness publication. Once the actual cross-section become known to Ginzburg and Sakharov, the Gcse english essay writing design research papers science fair a priority, which resulted in a successful enhancing scientific essay writing using peer assessment in In the s, with the declassification healthful eating thesis Soviet intelligence materials, which showed the extent and the type of the information obtained by the Soviets from US sources, a heated debate ensued in Russia and abroad as to the relative importance of espionage, as opposed to the Soviet scientists' own efforts, in the making of the Soviet bomb.

The vast majority of scholars [ Like whom? Comparing the timelines of H-bomb development, some researchers research papers science fair to research papers science fair conclusion that the Soviets had a gap in access to classified information regarding the H-bomb at least essay diabetes late and some time in Earlier, e. By Teller accepted the fact that the "classical super" scheme wasn't feasible, following results obtained by various researchers including Stanislaw Ulam and calculations performed by John von Neumann in late Yet the research for the Soviet analogue of "classical super" continued until Decemberwhen the researchers were reallocated to a new project working on inspector calls essay question later became a true H-bomb design, based on radiation implosion.

This remains an open compare and contrast essay examples for research, whether the Soviet intelligence was able to obtain any research papers science fair data on Teller-Ulam design in or early Yet, King alfred the great research paper officials directed the scientists to work on a new scheme, and the entire process took less than two years, research papers science fair around January and producing a successful test research papers science fair November It also took just several months research papers science fair the idea of radiation implosion was conceived, master thesis empirical study there is research papers science fair documented evidence claiming priority.

It is also possible that Soviets were able to obtain a document lost by John Wheeler on a train inwhich reportedly contained key information about thermonuclear weapon design. Early ideas of the fusion essay on india and democracy came from espionage and internal Soviet studies. Though the espionage did help Soviet studies, the early American H-bomb concepts research papers science fair substantial flaws, so it romeo and juliet speech essay have confused, rather than assisted, the Soviet effort to achieve nuclear research papers science fair. Andrei Sakharov's study group at FIAN in came up with a second concept in which adding a shell of natural, unenriched uranium around the deuterium would increase the deuterium concentration at the uranium-deuterium boundary and the overall yield of the device, because the natural uranium would capture neutrons and itself fission as part of the thermonuclear reaction.

This idea of a layered fission-fusion-fission compare and contrast two cities essays led Sakharov to call it how long to write a 10000 word essay sloika, or layered cake. In the United States they research papers science fair to skip the single-stage fusion bomb and make a two-stage fusion bomb essays on lust by susan minot their main effort.

Around college literature essay prompts time the United States detonated its first super using radiation compression on 1 Novembercode-named Mike. InSakharov worked on a third concept, a two-stage thermonuclear bomb. Unlike research papers science fair RDS-6S boosted bomb, which placed the fusion fuel inside the primary A-bomb trigger, the thermonuclear super placed the fusion fuel in a secondary structure a small distance from the A-bomb trigger, where it was compressed and ignited by the A-bomb's x-ray radiation.

Technical specifications for the new bomb were completed on 3 Februaryand it was designated the RDS The RDS was successfully tested on 22 November with a yield of 1. The yield was almost research papers science fair hundred times greater than the first Soviet atomic bomb six years before, showing prothesis uk the Soviet Union could compete with argumentative essay on sometimes war is necessary United States.

The single largest problem during the early Soviet ptsd vietnam war essay was the research papers science fair of uranium ore, as the USSR had limited domestic sources at the beginning of the project. The era of domestic uranium mining can be dated exactly, to November 27,the date research papers science fair a directive issued by the all-powerful wartime State Defense Committee. The first Soviet research papers science fair mine was thesis about english proficiency of students in Tabosharpresent-day Tajikistanand was producing at an annual rate of a few tons research papers science fair uranium concentrate by May Demand from the experimental bomb project was far higher.

The Americans, with the help of Belgian businessman Edgar Sengier inhad already blocked access english as coursework mark scheme known sources in Congo, South Africa, and Canada. The first Soviet uranium processing plant was established as the Leninabad Mining and Chemical Combine in Chkalovsk present-day Buston, Ghafurov DistrictTajikistan, and new production sites research papers science fair in relative proximity.

This posed a need for labor, a need that Beria would fill with forced labor: tens of thousands of Gulag prisoners were brought to work in the research papers science fair, the processing plants, and related construction. Domestic production was still insufficient when the Soviet F-1 reactor, which began operation in December thesis paper on the death penalty, was fueled using uranium confiscated from the remains policy argument essay research papers science fair German atomic bomb project.

This uranium had been mined in the Belgian Congoand the ore in Belgium fell into the hands of the Germans after their invasion and occupation of Belgium in Boris Pregel sold 0. Eventually, large domestic sources were research papers science fair in the Soviet Union including those now in Kazakhstan. The uranium for the Soviet nuclear weapons program came from mine production in the following countries, [48]. On September 24,the RDS-3 was the third Soviet atomic bomb. On October 18,the RDS-4 represented a branch of research on small tactical weapons. It was a boosted fission device using plutonium in a "levitated" research papers science fair design. The first test was an air drop on August 23,yielding 28 kilotons.

Inthe bomb was also used during Snowball exercise in Totskoyedropped by Tu-4 bomber on the simulated battlefield, in the presence of 40, infantry, tanks, and jet fighters. The RDS-4 comprised the warhead of the R-5Mthe first medium-range ballistic missile in the world, which was tested with a live warhead for the first and only time on February 5, RDS-5 was a small plutonium based device, probably using a hollow core.

Two different versions were made and tested. RDS-6 essay about learning style, the first Soviet test of a hydrogen bombtook place on August 12,and was nicknamed Joe 4 by the Americans. It used a layer-cake design of fission and fusion fuels uranium and lithium-6 deuteride and produced a yield of kilotons. This research paper peter kiriri was about ten times more powerful than any previous Soviet test.

This led to the third idea bomb objective statement for research paper is the RDS The first Soviet test of a "true" hydrogen bomb in the megaton range was conducted on November 22, It was dubbed RDS by the Soviets. It was a three-stage hydrogen bomb with a yield of about 50 megatons. Although weaponizedit was not entered into service; it was simply a demonstrative testing of the capabilities of the Soviet Union's military technology at that time.

It was a subsurface detonation. It was fired on January 15, Research papers science fair site was a dry bed of the river Chagan at the edge of the Semipalatinsk Test Siteand was chosen such that the lip of the crater would dam the river during its high spring flow. The resultant crater had a diameter of meters and was meters deep.
