JAEA
The is an Independent Administrative Institution formed on October 1, 2005 by a merger of two previous semi-governmental organizations. While it inherited the activities of both JNC and JAERI, it also inherited the nickname of JAERI, "Genken" 原研, an abbreviated word for "nuclear research". On April 10, 2007, JAEA officially joined the GNEP alliance. The other members in the alliance are Areva, Washington Group International and BWX. It is expected that the experience gained from the Rokkasho centrifuge enrichment plant will be a key contribution from JAEA. On April 1, 2016, JAEA transferred some of its laboratories to the National Institute of Radiological Sciences (NIRS), and the NIRS body was renamed to the National Institutes for Quantum and Radiological Science and Technology (QST) which includes existing laboratories of the NIRS. In 2018 JAEA estimated it would need about 1.9 trillion yen ($17.1 billion) to decommission 79 facilities over 70 years. Overview *E ...

JT-60
JT-60 (short for Japan Torus-60) is a large research tokamak, the flagship of Japan's magnetic fusion program, previously run by the Japan Atomic Energy Research Institute (JAERI) and currently run by the Japan Atomic Energy Agency's (JAEA) Naka Fusion Institute in Ibaraki Prefecture. It is properly an advanced tokamak, including a D-shaped plasma cross-section and active feedback control. First designed in the 1970s as the "Breakeven Plasma Test Facility" (BPTF), the goal of the system was to reach breakeven fusion power, a goal set for the US's TFTR, the UK's JET and the Soviet T-15. JT-60 began operations in 1985, and like the TFTR and JET that began operations only shortly before it, JT-60 demonstrated performance far below predictions. Over the next two decades, JET and JT-60 led the effort to regain the performance originally expected of these machines. JT-60 underwent two major modifications during this time, producing JT-60A, and then JT-60U (for "upgrade"). These change ...

J-PARC
J-PARC (Japan Proton Accelerator Research Complex) is a high intensity proton accelerator facility. It is a joint project between KEK and JAEA and is located at the Tokai campus of JAEA. J-PARC aims for the frontier in materials and life sciences, and nuclear and particle physics. J-PARC uses high intensity proton beams to create high intensity secondary beams of neutrons, hadrons, and neutrinos. Components J-PARC includes three main parts: the 400 MeV proton linear accelerator, the 3 GeV Rapid Cycling Synchrotron (RCS), and the 30 GeV Main Ring (MR) synchrotron. There are two main experimental areas: the Materials and Life Science Experimental Facility (MLF), where the proton beam from the RCS is used to create beams of either neutrons or muons for further study, and the Hadron Facility (HD), where the beam from the main ring is used to create heavy hadronic particles such as pions and kaons. The main ring beam is also used to create neutrino beams for analysis at the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Nuclear Cycle Development Institute
The Japan Nuclear Cycle Development Institute (JNC) was formed in October 1998 to develop advanced nuclear energy technology to complete the nuclear fuel cycle, particularly fast breeder reactors, advanced reprocessing, plutonium fuel fabrication and high-level radioactive waste management. It succeeded the Power Reactor and Nuclear Fuel Development Corporation (PNC). It merged with the Japan Atomic Energy Research Institute The Japan Atomic Energy Research Institute ( ja, 日本原子力研究所) (JAERI) is a former semi-governmental organization that existed for the purpose of further nuclear power in Japan. It was created in June 1956 by the Atomic Energy Basic Law ... (JAERI) in October 2005, becoming the Japan Atomic Energy Agency (JAEA).

National Institute Of Radiological Sciences
The (NIRS) is a radiation research institute in Japan. The NIRS was established in 1957 as the Japan's only one institute of radiology. The NIRS maintains various ion accelerators in order to study the effects of radiation of the human body and medical uses of radiation. The National Institute of Radiological Sciences hospital established in 1961 is a research hospital with a basic focus on radiation therapy. In 1993 the HIMAC (Heavy Ion Medical Accelerator in Chiba) of NIRS was launched, and in 1997 the Research Center for Charged Particle Therapy was opened as one of the leading medical centers using carbon ions are in operation. On April 1, 2016, the Japan Atomic Energy Agency The is an Independent Administrative Institution formed on October 1, 2005 by a merger of two previous semi-governmental organizations.

High-temperature Engineering Test Reactor
The high-temperature test reactor (HTTR) is a graphite- moderated gas-cooled research reactor in Ōarai, Ibaraki, Japan operated by the Japan Atomic Energy Agency. It uses long hexagonal fuel assemblies, unlike the competing pebble bed reactor designs. HTTR first reached its full design power of 30 MW (thermal) in 1999. Other tests have shown that the core can reach temperatures sufficient for hydrogen production via the sulfur-iodine cycle. Technical details The primary coolant is helium gas at a pressure of about 4 MPa, the inlet temperature of , and the outlet temperature of . The fuel is uranium oxide (enriched to an average of about 6%). See also * Very-high-temperature reactor *Hydrogen economy The hydrogen economy is using hydrogen to decarbonize economic sectors which are hard to electrify, essentially, the "hard-to-abate" sectors such as cement, steel, long-haul transport etc. In order to phase out fossil fuels and limit climate ...

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 produce 10 ...
