Reaktor Serba Guna–Gerrit Augustinus Siwabessy (RSG-GAS) ''(Multipurpose Reactor–Gerrit Augustinus Siwabessy)'' is a research reactor located in the Serpong neighborhood of South Tangerang, Banten, Indonesia. The reactor plays an important role in the Centre for Nuclear Industry Development, at Puspiptek, Serpong to serve other supporting laboratories, namely, radioisotope production, nuclear material science, reactor fuel element development, reactor safety, waste treatment, radio-metallurgy and nuclear-mechano laboratories. The reactor was constructed through a $50 million contract with Interatom Internationale Atomreaktorbau GmbH, a unit of the West German steelmaker Kraftwerke Union, which was awarded in 1981. The reactor's fuel rods have originated in the United States, France and the United Kingdom; the fuel was enriched in the United States and Russia. The International Atomic Energy Agency safeguards the reactor. It was inaugurated by the second President of I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nuclear Fuel
Nuclear fuel is material used in nuclear power stations to produce heat to power turbines. Heat is created when nuclear fuel undergoes nuclear fission. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission. The three most relevant fissile isotopes are uranium-233, uranium-235 and plutonium-239. When the unstable nuclei of these atoms are hit by a slow-moving neutron, they frequently split, creating two daughter nuclei and two or three more neutrons. In that case, the neutrons released go on to split more nuclei. This creates a self-sustaining chain reaction that is controlled in a nuclear reactor, or uncontrolled in a nuclear weapon. Alternatively, if the nucleus absorbs the neutron without splitting, it creates a heavier nucleus with one additional neutron. The processes involved in mining, refining, purifying, using, and disposing of nuclear fuel are collectively known as the nuclear fuel cycle. Not al ...

Nominal Power (photovoltaic)
The nominal power is the nameplate capacity of photovoltaic (PV) devices, such as solar cells, modules and systems, and is determined by measuring the electric current and voltage in a circuit, while varying the resistance under precisely defined conditions. The nominal power is important for designing an installation in order to correctly dimension its cabling and converters.Die Verwirrung um das Watt-Peak The confusion around watt-peak, 14 August 2009. The peak power is not the same as the power under actual radiation conditions. In practice, this will be approximately 15-20% lower due to the considerable heating of the solar cells.

Criticality (status)
In the operation of a nuclear reactor, criticality is the state in which a nuclear chain reaction is self-sustaining—that is, when reactivity is zero. In supercritical states, reactivity is greater than zero. Applications Criticality is the normal operating condition of a nuclear reactor, in which nuclear fuel sustains a fission chain reaction. A reactor achieves criticality (and is said to be critical) when each fission releases a sufficient number of neutrons to sustain an ongoing series of nuclear reactions. The International Atomic Energy Agency defines the ''first criticality date'' as the date when the reactor is made critical for the first time. This is an important milestone in the construction and commissioning of a nuclear power plant A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a electric gene ...

Sukarno
Sukarno). (; born Koesno Sosrodihardjo, ; 6 June 1901 – 21 June 1970) was an Indonesian statesman, orator, revolutionary, and nationalist who was the first president of Indonesia, serving from 1945 to 1967. Sukarno was the leader of the Indonesian struggle for independence from the Dutch colonialists. He was a prominent leader of Indonesia's nationalist movement during the colonial period and spent over a decade under Dutch detention until released by the invading Japanese forces in World War II. Sukarno and his fellow nationalists collaborated to garner support for the Japanese war effort from the population, in exchange for Japanese aid in spreading nationalist ideas. Upon Japanese surrender, Sukarno and Mohammad Hatta declared Indonesian independence on 17 August 1945, and Sukarno was appointed president. He led the Indonesian resistance to Dutch re-colonisation efforts via diplomatic and military means until the Dutch recognition of Indonesian indepe ...

International Atomic Energy Agency
The International Atomic Energy Agency (IAEA) is an intergovernmental organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for any military purpose, including nuclear weapons. It was established in 1957 as an autonomous organization within the United Nations system; though governed by its own founding treaty, the organization reports to both the General Assembly and the Security Council of the United Nations, and is headquartered at the UN Office at Vienna, Austria. The IAEA was created in response to growing international concern toward nuclear weapons, especially amid rising tensions between the foremost nuclear powers, the United States and the Soviet Union. U.S. President Dwight D. Eisenhower's " Atoms for Peace" speech, which called for the creation of an international organization to monitor the global proliferation of nuclear resources and technology, is credited with catalyzing the formation of the IAEA, whose treaty c ...
