High-Flux Advanced Neutron Application Reactor
The High-Flux Advanced Neutron Application Reactor (HANARO) (하나로) is a 30 MW multi-purpose research reactor located at Daejeon, Republic of Korea. It was designed by Korea Atomic Energy Research Institute (KAERI The Korea Atomic Energy Research Institute (KAERI) in Daejeon, South Korea was established in 1959 as the sole professional research-oriented institute for nuclear power in South Korea, and has rapidly built a reputation for research and developme ...) as a facility for research and development on the neutron science and its applications. HANARO has been playing a significant role as a national facility in the area of neutron science, the production of key radioisotopes, material testing for power reactor application, neutron transmutation doping ( NTD), neutron activation analysis, and neutron radiography. After the installation of a cold neutron source in 2010, it has been also serving as a regional and international facility for neutron science. Notes Referen ...

Research Reactor
Research reactors are nuclear fission-based nuclear reactors that serve primarily as a neutron source. They are also called non-power reactors, in contrast to power reactors that are used for electricity production, heat generation, or maritime propulsion. Purpose The neutrons produced by a research reactor are used for neutron scattering, non-destructive testing, analysis and testing of materials, production of radioisotopes, research and public outreach and education. Research reactors that produce radioisotopes for medical or industrial use are sometimes called isotope reactors. Reactors that are optimised for beamline experiments nowadays compete with spallation sources. Technical aspects Research reactors are simpler than power reactors and operate at lower temperatures. They need far less fuel, and far less fission products build up as the fuel is used. On the other hand, their fuel requires more highly enriched uranium, typically up to 20% U-235, although some use 93 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daejeon
Daejeon () is South Korea's fifth-largest metropolis, with a population of 1.5 million as of 2019. Located in the central-west region of South Korea alongside forested hills and the Geum River, the city is known both for its technology and research institutions, and for celebrating its natural environment, with most mountains, hot springs, and rivers freely open for public use. Daejeon serves as a hub of transportation for major rail and road routes, and is approximately 50 minutes from the capital, Seoul, by KTX or SRT high speed rail. Daejeon (along with Seoul, Gwacheon and Sejong City) are collectively South Korea's administration hubs. The city is home to 23 universities and colleges, including Korea Advanced Institute of Science and Technology (KAIST) and Chungnam National University, as well as government research institutes, and research and development centers for global companies such as Samsung, LG, mostly located in the city's Daedeok Science Town.

Republic Of Korea
South Korea, officially the Republic of Korea (ROK), is a country in East Asia, constituting the southern part of the Korean Peninsula and sharing a 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 adjacent islands. It has a population of 51.75 million, of which roughly half live in the Seoul Capital Area, the 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 first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Silla and Balhae in the late 7th century, Korea was ruled by the Goryeo dynasty (918–1392) and the Joseon dynasty (1392–1897). The succeeding Korean Empire (1897–1910) was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KAERI
The Korea Atomic Energy Research Institute (KAERI) in Daejeon, South Korea was established in 1959 as the sole professional research-oriented institute for nuclear power in South Korea, and has rapidly built a reputation for research and development in various fields. In 1995 KAERI designed and constructed the nation's first multipurpose research reactor, HANARO based on the Canadian MAPLE design. KAERI is dedicated to finding a wide range of uses for atomic energy. As examples, KAERI developed the world's first radiopharmaceutical "Milican injection" for treating liver cancer. KAERI has made significant contributions to the nation's nuclear technology development. After Korea achieved self-reliance in nuclear core technologies, KAERI have transferred highly developed technologies to local industries for practical applications. The Korea Institute of Nuclear Safety (KINS), responsible for supporting the government in regulatory and licensing works, and the Nuclear Environment Tec ...

Doping (semiconductor)
In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. Small numbers of dopant atoms can change the ability of a semiconductor to conduct electricity. When on the order of one dopant atom is added per 100 million atoms, the doping is said to be ''low'' or ''light''. When many more dopant atoms are added, on the order of one per ten thousand atoms, the doping is referred to as ''high'' or ''heavy''. This is often shown as ''n+'' for n-type doping or ''p+'' for p-type doping. (''See the article on semiconductors for a more detailed description of the doping mechanism.'') A semiconductor doped to such high levels that it acts more like a conductor than a semiconductor is referred to as a degenerate semiconductor. A semiconductor can be considered i-type semiconductor if it has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science And Technology In South Korea
Science and technology in South Korea has advanced throughout the decades. The advancement of science and technology has become an integral part of economic planning in South Korea. Fast-growing industries have created a massive demand for new and more advanced technologies. Additionally, Korean scientists propose that the advancement of science and technology in partnership with North Korea could help facilitate the peaceful reunification of North Korea and South Korea. In the pursuit of advancement, South Korea has taken a centralized approach. South Korea was ranked 5th in the Global Innovation Index in 2021 Korean Federation of Science and Technology Societies (KOFST) The Korean Federation of Science and Technology Societies was established in 1966 and consists of 780 organizations as of 2012. The goals of the KOFST are to make the sharing of technology and research data between these societies easier and to encourage and facilitate the cooperation of Pacific Rim countries. ...

Neutron Facilities
A neutron research facility is most commonly a big laboratory operating a large-scale neutron source that provides thermal neutrons to a suite of research instruments. The neutron source usually is a research reactor or a spallation source. In some cases, a smaller facility will provide high energy neutrons (e.g. 2.5 MeV or 14 MeV neutron#Fusion neutrons, fusion neutrons) using existing neutron generator technologies. List of neutron facilities The following list is intended to be exhaustive and to cover active facilities as well as those that are shut down. ;Australia * ANSTO-HIFAR Reactor, Sydney * Open-pool Australian lightwater reactor (OPAL) ;Bangladesh * Atomic Energy Research Establishment (Bangladesh), Atomic Energy Research Establishment (AERE), Bangladesh Atomic Energy Commission(BAEC) ;Canada * Canadian Neutron Beam Centre, NRC Canadian Neutron Beam Centre at Chalk River Laboratories * RE-Labs Inc. – Single Event Effects Testing Services ;China * China Spallati ...
