Jaduguda Uranium Mine
The Jaduguda Mine (also spelt as Jadugoda or Jadugora) is a uranium mine in Jaduguda village in the Purbi Singhbhum district of the Indian state of Jharkhand. It commenced operation in 1967 and was the first uranium mine in India. The deposits at this mine were discovered in 1951. As of March 2012, India possesses eight functional uranium mines, including this Jaduguda Mine. A new mine, Tummalapalle uranium mine is discovered and mining is going to start from it. Mining activities were suspended in 2014 following an inquiry into the diversion of forest land of the mine. Uranium Corporation of India Limited (UCIL) expects mining activity to resume at Jaduguda in 2017. The Jaduguda mine produces up to 25% of the raw materials needed to fuel India's nuclear reactors. Geography The Jaduguda uranium mine is an underground mining mine located in the Purbi Singhbhum district of Jharkhand. The mine is located at least 640 meters below the earth's surface and is accessible by a 5-met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purbi Singhbhum District
East Singhbhum is one of the 24 districts of Jharkhand, India. It was created on 16 January 1990. More than 50% of the district is covered by dense forests and mountains, where wild animals once roamed freely. It is known for being a centre of industry since Jamshedpur, the most populous city in Jharkhand, is located here. Geography The district is bounded on the east by Jhargram district, on the north by Purulia district, both of West Bengal, on the west by Seraikela Kharsawan district, and on the south by Mayurbhanj district of Odisha. Total area of the district is 3,562 kilometers. The district is a mineral rich and industrialized region. Dalma Wildlife Sanctuary is a popular biosphere reserve known lively for its animals. Dalma Hills is stretching over Jharkhand and West Bengal. It is on the northern region of Jamshedpur. A lot of minerals are found here. Politics Administration There are six Vidhan Sabha constituencies in this district: Baharagora, Ghatsila, Potka, Jug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium-235
Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster. Its fission cross section for slow thermal neutrons is about 584.3±1 barns. For fast neutrons it is on the order of 1 barn. Most but not all neutron absorptions result in fission; a minority result in neutron capture forming uranium-236. Natural decay chain :\begin \ce \begin \ce \\ \ce \end \ce \\ \ce \begin \ce \\ \ce \end \ce \end Fission properties The fission of one atom of uranium-235 releases () inside the reactor. That corresponds to 19.54 TJ/ mol, or 83.14 TJ/kg. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Mines In India
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99.2739–9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
