IFMIF
The International Fusion Materials Irradiation Facility, also known as IFMIF, is a projected material testing facility in which candidate materials for the use in an energy producing fusion reactor can be fully qualified. IFMIF will be an accelerator-driven neutron source producing a high intensity fast neutron flux with a spectrum similar to that expected at the first wall of a fusion reactor using a deuterium-lithium nuclear reaction. The IFMIF project was started in 1994 as an international scientific research program, carried out by Japan, the European Union, the United States, and Russia, and managed by the International Energy Agency. Since 2007, it has been pursued by Japan and the European Union under the Broader Approach Agreement in the field of fusion energy research, through the IFMIF/EVEDA project, which conducts engineering validation and engineering design activities for IFMIF. The construction of IFMIF is recommended in the European Roadmap for Research Infrastruc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fusion For Energy
Fusion for Energy (F4E) is a joint undertaking of the European Atomic Energy Community (Euratom) that is responsible for the EU's contribution to the International Thermonuclear Experimental Reactor (ITER), the world's largest scientific partnership aiming to demonstrate fusion as a viable and sustainable source of energy. The organisation is officially named European Joint Undertaking for ITER and the Development of Fusion Energy and was created under article 45 of the Treaty establishing the European Atomic Energy Community by the decision of the Council of the European Union on 27 March 2007 for a period of 35 years. F4E counts 450 members of staff. Its seat is located in Barcelona, Spain, and it has offices in Saint-Paul-lès-Durance, France, and Garching, Germany. One of its main tasks is to work together with European industry and research organisations to develop and provide a wide range of high technology components for the ITER project.

DEMOnstration Power Station
DEMO refers to a proposed class of nuclear fusion experimental reactors that are intended to demonstrate the net production of electric power from nuclear fusion. Most of the ITER partners have plans for their own DEMO-class reactors. With the possible exception of the EU and Japan, there are no plans for international collaboration as there was with ITER. Plans for DEMO-class reactors are intended to build upon the ITER experimental nuclear fusion reactor. The most well-known and documented DEMO-class reactor design is that of the European Union (EU). The following parameters have been used as a baseline for design studies: the EU DEMO should produce at least 2000 megawatts (2 gigawatts) of fusion power on a continuous basis, and it should produce 25 times as much power as required for scientific breakeven, which does not include the power required to operate the reactor. The EU DEMO design of 2 to 4 gigawatts of thermal output will be on the scale of a modern electric power s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITER
ITER (initially the International Thermonuclear Experimental Reactor, ''iter'' meaning "the way" or "the path" in Latin) is an international nuclear fusion research and engineering megaproject aimed at creating energy by replicating, on Earth, the fusion processes of the Sun. Upon completion of construction of the main reactor and first plasma, planned for late 2025, it will be the world's largest magnetic confinement plasma physics experiment and the largest experimental tokamak nuclear fusion reactor. It is being built next to the Cadarache facility in southern France. ITER will be the largest of more than 100 fusion reactors built since the 1950s, with ten times the plasma volume of any other tokamak operating today. The long-term goal of fusion research is to generate electricity. ITER's stated purpose is scientific research, and technological demonstration of a large fusion reactor, without electricity generation. ITER's goals are to achieve enough fusion to produc ...

Plasma-facing Material
In nuclear fusion power research, the plasma-facing material (or materials) (PFM) is any material used to construct the plasma-facing components (PFC), those components exposed to the plasma within which nuclear fusion occurs, and particularly the material used for the lining the first wall or divertor region of the reactor vessel. Plasma-facing materials for fusion reactor designs must support the overall steps for energy generation, these include: #Generating heat through fusion, #Capturing heat in the first wall, #Transferring heat at a faster rate than capturing heat. #Generating electricity. In addition PFMs have to operate over the lifetime of a fusion reactor vessel by handling the harsh environmental conditions, such as: # Ion bombardment causing physical and chemical sputtering and therefore erosion. # Ion implantation causing displacement damage and chemical composition changes # High-heat fluxes (e.g. 10 MW/m^2) due to ELMS and other transients. # Limited tritium co ...

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed in ...

Fusion Power
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2022, only one design, an inertial confinement laser-driven fusion machine at the US National Ignition Facility, has conclusively produced a positive fusion energy gain factor, i.e. more power output than input. Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides extremely long confinement times that reach the conditions needed for fusion e ...

Post Irradiation Examination
Post Irradiation Examination (PIE) is the study of used nuclear materials such as nuclear fuel. It has several purposes. It is known that by examination of used fuel that the failure modes which occur during normal use (and the manner in which the fuel will behave during an accident) can be studied. In addition information is gained which enables the users of fuel to assure themselves of its quality and it also assists in the development of new fuels. After major accidents the core (or what is left of it) is normally subject to PIE in order to find out what happened. One site where PIE is done is the ITU which is the EU centre for the study of highly radioactive materials. Materials in a high radiation environment (such as a reactor) can undergo unique behaviors such as swelling and non-thermal creep. If there are nuclear reactions within the material (such as what happens in the fuel), the stoichiometry will also change slowly over time. These behaviors can lead to new materia ...

SCK•CEN
SCK CEN (the Belgian Nuclear Research Centre), until 2020 shortened as SCK•CEN, is the Belgian nuclear research centre located in Mol, Belgium, more specifically near the township of Donk. SCK CEN is a global leader in the field of nuclear research, services, and education. History SCK CEN was founded in 1952 and originally named Studiecentrum voor de Toepassingen van de Kernenergie (Research Centre for the Applications of Nuclear Energy), abbreviated to STK. Land was bought in the municipality of Mol, and over the next years many technical, administrative, medical, and residential buildings were constructed on the site. From 1956 to 1964 four nuclear research reactors became operational: the BR 1, BR 2, BR 3, the first pressurized water reactor in Europe, and VENUS. In 1963 SCK CEN already employed 1600 people, a number that would remain about the same over the next decades. In 1970 SCK CEN widened its field of activities outside the nuclear sector, but the emphasis rema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
