Tōkai Nuclear Power Plant
The was Japan's first commercial nuclear power plant. The first unit was built in the early 1960s to the British Magnox design, and generated power from 1966 until it was decommissioned in 1998. A second unit, nominally a separate power station called , was built at the site in the 1970s, the first in Japan to produce over 1000 MW of electricity. The site is located in Tokai in the Naka District in Ibaraki Prefecture, Japan and is operated by the Japan Atomic Power Company. The total site area amounts to 0.76 km2 (188 acres) with 0.33 km2, or 43% of it, being green area that the company is working to preserve. The plant has been not operational since the reactor shut down automatically due to the 2011 Tōhoku earthquake and tsunami. Reactors on site Unit 1 This reactor was built based on the British-developed Magnox technology for dual-use. Unit 1 is the first full-size nuclear reactor to be decommissioned in Japan.

Unicameral
Unicameralism (from ''uni''- "one" + Latin ''camera'' "chamber") is a type of legislature consisting of one house or assembly that legislates and votes as one. Unicameralism has become an increasingly common type of legislature, making up nearly 60% of all national legislatures and an even greater share of subnational legislatures. Sometimes, as in New Zealand and Denmark, unicameralism comes about through the abolition of one of two bicameral chambers, or, as in Sweden, through the merger of the two chambers into a single one, while in others a second chamber has never existed from the beginning. Rationale for unicameralism and criticism The principal advantage of a unicameral system is more efficient lawmaking, as the legislative process is simpler and there is no possibility of gridlock (politics), deadlock between two chambers. Proponents of unicameralism have also argued that it reduces costs, even if the number of legislators stays the same, since there are fewer instituti ...

Nuclear Reprocessing
Nuclear reprocessing is the chemical separation of fission products and actinides from spent nuclear fuel. Originally, reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors. The reprocessed uranium, also known as the spent fuel material, can in principle also be re-used as fuel, but that is only economical when uranium supply is low and prices are high. Nuclear reprocessing may extend beyond fuel and include the reprocessing of other nuclear reactor material, such as Zircaloy cladding. The high radioactivity of spent nuclear material means that reprocessing must be highly controlled and carefully executed in advanced facilities by specialized personnel. Numerous processes exist, with the chemical based PUREX process dominating. Alternatives include heating to drive off volatile elements, burning via oxidation, and fluoride vola ...

Tokaimura Nuclear Accident
The Tokaimura nuclear accidents refer to two nuclear related incidents near the village of Tōkai, Ibaraki, Tōkai, Ibaraki Prefecture, Japan. The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation, Power Reactor and Nuclear Fuel Development Corporation (PNC) radioactive waste bituminisation facility. Over twenty people were exposed to radiation. The second was a criticality accident at a separate fuel reprocessing facility belonging to JCO (company), Japan Nuclear Fuel Conversion Co. (JCO) on 30 September 1999 due to improper handling of liquid uranium fuel for an experimental reactor. The incident spanned approximately 20 hours and resulted in radiation exposure for 667 people and the deaths of two workers. Most of the technicians were hospitalised for serious injuries. It was determined that the accidents were due to inadequate regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Atomic Energy Research Institute
The Japan Atomic Energy Research Institute () (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. It merged with Japan Nuclear Cycle Development Institute and became Japan Atomic Energy Agency on October 1, 2005, which currently carries out the purpose outlined in the law. It was called Genken (原研) for short. Development A small number of researchers in Japan studied at Argonne National Laboratory in America with the purpose of gaining knowledge that could be taken back to Japan in 1955. Kinichi Torikai was one of those researchers, and he later became president of JAERI. After returning, facilities for nuclear research were established in Tōkai, Ibaraki. In the 1950s, it was decided that individual electric utilities would import reactor types to meet the rapidly increasing demand for energy in the post-war Japan. In September 1955, JAERI was establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
