Villages Of Japan
A is a local administrative unit in Japan. It is a local public body along with , , and . Geographically, a village's extent is contained within a prefecture. It is larger than an actual settlement, being in actuality a subdivision of a rural , which are subdivided into towns and villages with no overlap and no uncovered area. As a result of mergers and elevation to higher statuses, the number of villages in Japan is decreasing. Currently, 13 prefectures no longer have any villages: Tochigi (since March 20, 2006), Fukui (since March 3, 2006), Ishikawa (since March 1, 2005), Shizuoka (since July 1, 2005), Hyōgo (since April 1, 1999), Mie (since November 1, 2005), Shiga (since January 1, 2005), Hiroshima (since November 5, 2004), Yamaguchi (since March 20, 2006), Ehime (since January 16, 2005), Kagawa (since April 1, 1999), Nagasaki (since October 1, 2005), and Saga (since March 20, 2006).

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, built at the site in the 1970s, was 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 British developed Magnox technology for dual-use. Unit 1 will be the first nuclear reactor to be decommissioned in Japan. The experience in decommissioning this plant is expected to be of use in the future when more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibaraki 5th District
, the House of Representatives of Japan is elected from a combination of multi-member districts and single-member districts, a method called Parallel voting. Currently, 176 members are elected from 11 multi-member districts (called proportional representation blocks or PR blocks) by a party-list system of proportional representation (PR), and 289 members are elected from single-member districts, for a total of 465. 233 seats are therefore required for a majority. Each PR block consists of one or more prefectures, and each prefecture is divided into one or more single-member districts. In general, the block districts correspond loosely to the major regions of Japan, with some of the larger regions (such as Kantō) subdivided. History Until the 1993 general election, all members of the House of Representatives were elected in multi-member constituencies by single non-transferable vote. In 1994, Parliament passed an electoral reform bill that introduced the current system of pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicameral
Unicameralism (from ''uni''- "one" + Latin ''camera'' "chamber") is a type of legislature, which consists of one house or assembly, that legislates and votes as one. Unicameral legislatures exist when there is no widely perceived need for multicameralism (two or more chambers). Many multicameral legislatures were created to give separate voices to different sectors of society. Multiple houses allowed, for example, for a guaranteed representation of different social classes (as in the Parliament of the United Kingdom or the French States-General). 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 ...

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. A breeder reactor is not restricted to using recycled plutonium and uranium. It can employ all the actinides, closing the nuclear fuel cycle and potentially multiplying the energy extracted from natural uranium by about 60 times. Reprocessing must be highly controlled and carefully executed in advanced facilities by highly specialized personnel. Fuel bundles which arrive at the sites from nuclear power plants (after having cooled down for several years) are completely dissolv ...

Tokaimura Nuclear Accident
There have been two noteworthy nuclear accidents at the Tōkai village nuclear campus, 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 (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 Japan Nuclear Fuel Conversion Co. (JCO) on 30 September 1999 due to improper handling of liquid uranium fuel. The incident spanned approximately 20 hours and resulted in radiation exposure for 667 people and the death of two workers. Nuclear power in Japan Nuclear power was an important energy alternative for natural-resource-poor Japan to limit dependence on imported energy, providing approximately 30% of Japan’s electricity up until the Fukushima nuclear disaster of 2011, aft ...

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. 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 Septe ...
