Nuclear Power In China
China is one of the world's largest producers of nuclear power. The country ranks third in the world both in total nuclear power capacity installed and electricity generated, accounting for around one tenth of global nuclear power generated. Nuclear power contributed 4.9% of the total Chinese electricity production in 2019, with 348.1 TWh. As of September 2022, China operates a total of 53 nuclear reactors, with a total capacity of 55.6 gigawatt (GW). This was short of the previous target of 58GW of installed capacity by 2020. More than 20 reactors are under construction with a total capacity of 24.2 GW. Nuclear power has been looked into as an alternative to coal due to increasing concerns about air quality, climate change and fossil fuel shortages. The China General Nuclear Power Group has articulated the goal of 200 GW by 2035, produced by 150 additional reactors. China has two major nuclear power companies, the China National Nuclear Corporation operating mainly in nort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taishan Nuclear Power Plant
The Taishan Nuclear Power Plant () is a nuclear power plant in Taishan, Guangdong province, China. The plant features two operational EPR reactors. The first unit, Taishan 1, entered commercial service in December 2018, but was shut down from July 2021 to August 2022 to investigate and fix issues with fuel rod cladding. The second unit, Taishan 2, entered commercial service in September 2019. Delays at other EPR construction sites in Finland and France meant that Taishan was the first nuclear power plant to have an operational EPR. The project is owned by Guangdong Taishan Nuclear Power Joint Venture Company Limited (TNPC), which is 70% owned by China Guangdong Nuclear Power Group (CGNPC) and 30% by Électricité de France (EDF). The plant's twin reactors each have a nameplate capacity 1750 MWe. Its Arabelle generators are the largest single-piece electrical generators in the world, each weighing 495 tonnes and built by Dongfang Electric. Of the 3500 MWe gross delive ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC) launched by Mao Zedong in 1966, and lasting until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. The Revolution marked the effective commanding return of Mao –who was still the Chairman of the Chinese Communist Party (CCP)– to the centre of power, after a period of self-abstention and ceding to less radical leadership in the aftermath of the Mao-led Great Leap Forward debacle and the Great Chinese Famine (1959–1961). The Revolution failed to achieve its main goals. Launching the movement in May 1966 with the help of the Cultural Revolution Group, Mao charged that bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to "bombard the headqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorium
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when finely divided. All known thorium isotopes are unstable. The most stable isotope, 232Th, has a half-life of 14.05 billion years, or about the age of the universe; it decays very slowly via alpha decay, starting a decay chain named the thorium series that ends at stable 208 Pb. On Earth, thorium and uranium are the only significantly radioactive elements that still occur naturally in large quantities as primordial elements. Thorium is estimated to be over three times as abundant as uranium in the Earth's crust, and is chiefly refined from monazite sands as a by-product of extracti ...

Uranium
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Committee Of The Chinese Communist Party
The Central Committee of the Chinese Communist Party, officially the Central Committee of the Communist Party of China, is a political body that comprises the top leaders of the Chinese Communist Party (CCP). It is currently composed of 205 full members and 171 alternate members (see list). Members are nominally elected once every five years by the National Congress of the Chinese Communist Party. In practice, the selection process is done privately, usually through consultation of the CCP's Politburo and its corresponding Standing Committee. The Central Committee is, formally, the "party's highest organ of authority" when the National Congress is not in a plenary session. According to the CCP's constitution, the Central Committee is vested with the power to elect the General Secretary and the members of the Politburo and its Standing Committee, as well as the Central Military Commission. It endorses the composition of the Secretariat and the Central Commission for Discipli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Changchun Institute Of Atomic Energy
Changchun (, ; ), also romanized as Ch'angch'un, is the capital and largest city of Jilin Province, People's Republic of China. Lying in the center of the Songliao Plain, Changchun is administered as a , comprising 7 districts, 1 county and 3 county-level cities. According to the 2020 census of China, Changchun had a total population of 9,066,906 under its jurisdiction. The city's metro area, comprising 5 districts and 1 development area, had a population of 5,019,477 in 2020, as the Shuangyang and Jiutai districts are not urbanized yet. It is one of the biggest cities in Northeast China, along with Shenyang, Dalian and Harbin. The name of the city means "long spring" in Chinese. Between 1932 and 1945, Changchun was renamed Xinjing () or Hsinking by the Kwantung Army as it became the capital of the Imperial Japanese puppet state of Manchukuo, occupying modern Northeast China. After the foundation of the People's Republic of China in 1949, Changchun was established as the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
