National Atomic Energy Commission
The National Atomic Energy Commission ( es, Comisión Nacional de Energía Atómica, CNEA) is the Argentine government agency in charge of nuclear energy research and development. The agency was created on May 31, 1950, with the mission of developing and controlling nuclear energy for peaceful purposes in the country. CNEA's facilities include the Bariloche Atomic Centre (in San Carlos de Bariloche), Constituyentes Atomic Centre (in Buenos Aires), and Ezeiza Atomic Centre (in Ezeiza, Buenos Aires Province). CNEA operates research reactors at each of these sites. History Officially established by President Juan Perón's Decree No 10.936, CNEA filled the need for a state organ to oversee the funding of the Huemul Project in Bariloche. Before CNEA came into being, the project was funded by the Dirección de Migraciones. In practice CNEA had only four members (Juan Domingo Perón, González, Mendé and Ronald Richter). In 1951, decree 9697 created another agency, the Direcci� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comisión Nacional De Actividades Espaciales
Comisión Nacional de Actividades Espaciales (CONAE; in English, National Space Activities Commission) is the civilian agency of the government of Argentina in charge of the national space programme. History Sociedad Argentina Interplanetaria During the 1940s, Teófilo Tabanera organized a group of foreign and Argentine specialists as the Sociedad Argentina Interplanetaria, SAI (Argentine Interplanetary Society).

Nuclear 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 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Reactor 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 a ...

Reactor Protection System
A reactor protection system (RPS) is a set of nuclear safety and security components in a nuclear power plant designed to safely shut down the reactor and prevent the release of radioactive materials. The system can "trip" automatically (initiating a scram), or it can be tripped by the operators. Trips occurs when the parameters meet or exceed the limit setpoint. A trip of the RPS results in full insertion (by gravity in pressurized water reactors or high-speed injection in boiling water reactors) of all control rods and shutdown of the reactor. Pressurized water reactors Some of the measured parameters for US pressurized water plants would include: *"High power", auctioneered between high nuclear power and high differential temperature (delta T) between the inlet and outlet of the reactor vessel (a measure of the thermal power for a given RCS flowrate). *"High startup rate" (active below 10-4 percent power) at low power levels. *"High pressurizer pressure" *"Low reactor coola ...

Radiation Protection
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive contamination. Ionizing radiation is widely used in industry and medicine, and can present a significant health hazard by causing microscopic damage to living tissue. There are two main categories of ionizing radiation health effects. At high exposures, it can cause "tissue" effects, also called "deterministic" effects due to the certainty of them happening, conventionally indicated by the unit gray and resulting in acute radiation syndrome. For low level exposures there can be statistically elevated risks of radiation-induced cancer, called " stochastic effects" due to the uncertainty of them happening ...
