Kori Nuclear Power Plant
The Kori Nuclear Power Plant (Korean: 고리원자력발전소, Hanja: 古里原子力發電所) is a South Korean nuclear power plant located in Kori, a suburban village in Busan. It is the world's largest fully operational nuclear generating station by total reactor count and the number of currently operational reactors since 2016, after it exceeded in nameplate capacity Canada's Bruce Nuclear Generating Station. It is owned and operated by Korea Hydro & Nuclear Power, a subsidiary of KEPCO. The first reactor began commercial operation in 1978 and operated until 2017 when it was decommissioned. Units 2, 3, and 4 started commercial operations in the 1980s. All reactors on site are pressurized water reactors. Reactors An expansion of the plant begun in 2006 added four new Korean-sourced reactors, the so-called Shin Kori reactors (shin meaning "new"). The first pair of Shin Kori reactors are of the OPR-1000 design, while the second two are the APR-1400 design. Shin Kori 1 and 2 ...

South Korea
South Korea, officially the Republic of Korea (ROK), is a country in East Asia, constituting the southern part of the Korea, Korean Peninsula and sharing a Korean Demilitarized Zone, land border with North Korea. Its western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. South Korea claims to be the sole legitimate government of the entire peninsula and List of islands of South Korea, adjacent islands. It has a Demographics of South Korea, population of 51.75 million, of which roughly half live in the Seoul Capital Area, the List of metropolitan areas by population, fourth most populous metropolitan area in the world. Other major cities include Incheon, Busan, and Daegu. The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its Gojoseon, first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Unified Silla, Silla and Balhae in the ...

Fukushima Daiichi Nuclear Disaster
The was a nuclear accident in 2011 at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami, which occurred on the afternoon of 11 March 2011 and remains the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The result was the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES) after initially being classified as level five, and thus joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl (335,000 people evacuated) and Fukushima (154,000 evacuate ...

Nuclear Power In South Korea
Nuclear power is a major power source in South Korea, providing 29% of the country's electricity. The total electrical generation capacity of the nuclear power plants of South Korea is 20.5 GWe from 23 reactors, equivalent to 22% of South Korea's total electrical generation capacity. In 2012 South Korea had plans for significant expansion of its nuclear power industry, and to increase nuclear's share of generation to 60% by 2035. Eleven more reactors were scheduled to come online in the period 2012 to 2021, adding 13.8 GWe in total. However, in 2013 the government submitted a reduced draft plan to parliament for nuclear output of up to 29% of generation capacity by 2035, following several scandals related to falsification of safety documentation. This plan still involved increasing 2035 nuclear capacity by 7 GWe, to 43 GWe. However, responding to widespread public concerns after the Fukushima Daiichi nuclear disaster in Japan, the high earthquake risk in South Kor ...

Control Rod
Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves decaying. These elements have different neutron capture cross sections for neutrons of various energies. Boiling water reactors (BWR), pressurized water reactors (PWR), and heavy-water reactors (HWR) operate with thermal neutrons, while breeder reactors operate with fast neutrons. Each reactor design can use different control rod materials based on the energy spectrum of its neutrons. Control rods have been used in nuclear aircraft engines like Project Pluto as a method of control. Operating principle Control rods are inserted into the core of a nuclear reactor and adjusted in order to control the rate of the nuclear chain reaction and, thereby, the thermal power output of the reactor, the rate of stea ...

Spent Nuclear Fuel
Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and depending on its point along the nuclear fuel cycle, it may have considerably different isotopic constituents. The term "fuel" is slightly confusing, as it implies a combustion of some type, which does not occur in a nuclear power plant. Nevertheless, this term is generally accepted. Nature of spent fuel Nanomaterial properties In the oxide fuel, intense temperature gradients exist that cause fission products to migrate. The zirconium tends to move to the centre of the fuel pellet where the temperature is highest, while the lower-boiling fission products move to the edge of the pellet. The pellet is likely to contain many small bubble-like pores that form during use; the fission product xenon migrates to these voids. Some of this xeno ...

Hyundai Group
Hyundai Group (; ) is a South Korean conglomerate founded by Chung Ju-yung. The first company in the group was founded in 1947 as a construction company. With government assistance, Chung and his family members rapidly expanded into various industries, eventually becoming South Korea's second chaebol. Chung Ju-yung was directly in control of the company until his death in 2001. The company spun off many of its better known businesses after the 1997 Asian financial crisis and founder Chung Ju-yung's death, including Hyundai Motor Group, Hyundai Department Store Group, and Hyundai Heavy Industries Group. The Hyundai Group now focuses on elevators and tourism to Mount Kumgang. Etymology The name "Hyundai" comes from the Korean word (hanja form), which means "modernity". History * In 1947, Hyundai Togun (Hyundai Engineering and Construction), the initial company of the Hyundai Group, was established by Chung Ju-yung. Hyundai Construction began operating outside of South K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bechtel
Bechtel Corporation () is an American engineering, procurement, construction, and project management company founded in San Francisco, California, and headquartered in Reston, Virginia. , the ''Engineering News-Record'' ranked Bechtel as the second largest construction company in the United States. History Founding and early years Bechtel's business activities began in 1898, when cattle farmer Warren A. Bechtel moved from Peabody, Kansas, to the Oklahoma Territory to construct railroads with his team of mules. Bechtel moved his family frequently between construction sites around the western United States for the next several years, eventually moving to Oakland, California, in 1904, where he worked as the superintendent on the Western Pacific Railroad. In 1906, W. A. Bechtel won his first subcontract to build part of the Oroville-to-Oakland section of the Western Pacific Railroad.
