Monju (other)
was a Japanese sodium-cooled fast reactor, located near the Tsuruga Nuclear Power Plant, Fukui Prefecture. Its name is a reference to Manjusri. Construction started in 1986 and the reactor achieved criticality for the first time in April 1994. The reactor has been inoperative for most of the time since it was originally built. It was last operated in 2010 and is now closed. Monju was a sodium cooled, MOX-fueled, loop-type reactor with three primary coolant loops, designed to produce 280 MWe from 714 MWt. It had a breeding ratio of approximately 1.2. The plant is located on a site that spans 1.08 km2 (267 acres), the buildings occupy 28,678 m2 (7 acres), and it has 104,680 m2 of floor space. An accident in December 1995, in which a sodium leak caused a major fire, forced a shutdown. A subsequent scandal involving a cover-up of the scope of the accident delayed its restart until May 6, 2010, with renewed criticality reached on May 8, 2010. In August 2010 anoth ...

International Nuclear Event Scale
The International Nuclear and Radiological Event Scale (INES) was introduced in 1990 by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents. The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times as severe as the previous level. Compared to earthquakes, where the event intensity can be quantitatively evaluated, the level of severity of a human-made disaster, such as a nuclear accident, is more subject to interpretation. Because of this subjectivity, the INES level of an incident is assigned well after the fact. The scale is therefore intended to assist in disaster-aid deployment. Details A number of criteria and indicators are defined to assure coherent reporting of nuclear events by different official authorities. There ...

Plutonium-241
Plutonium-241 ( or Pu-241) is an isotope of plutonium formed when plutonium-240 captures a neutron. Like some other plutonium isotopes (especially 239Pu), 241Pu is fissile, with a neutron absorption cross section about one-third greater than that of 239Pu, and a similar probability of fissioning on neutron absorption, around 73%. In the non-fission case, neutron capture produces plutonium-242. In general, isotopes with an odd number of neutrons are both more likely to absorb a neutron and more likely to undergo fission on neutron absorption than isotopes with an even number of neutrons. Decay properties Plutonium-241 is a beta emitter with a half-life of 14.3 years, corresponding to a decay of about 5% of 241Pu nuclei over a one-year period. This decay has a ''Q''-value of and a mean of , and does not emit gamma rays. The longer spent nuclear fuel waits before reprocessing, the more 241Pu decays to americium-241, which is nonfissile (although fissionable by fast neutrons ...

is the capital of Ishikawa Prefecture in central Japan. , the city had an estimated population of 466,029 in 203,271 households, and a population density of 990 persons per km2. The total area of the city was . Etymology The name "Kanazawa" (, ), which literally means "marsh of gold", is said to derive from the legend of the peasant Imohori Togoro (literally "Togoro Potato-digger"), who was digging for potatoes when flakes of gold washed up. The well in the grounds of Kenroku-en is known as to acknowledge these roots. The area where Kanazawa is was originally known as Ishiura, whose name is preserved at the Ishiura Shrine near Kenrokuen. The area around Kanazawa was part of ancient Kaga Province. History Muromachi period During the Muromachi period (1336 to 1573), as the power of the central shōguns in Kyoto was waning, Kaga Province came under the control of the Ikkō-ikki, followers of the teachings of priest Rennyo, of the sect, who displaced the official governo ...

Gag Order
A gag order (also known as a gagging order or suppression order) is an order, typically a legal order by a court or government, restricting information or comment from being made public or passed on to any unauthorized third party. The phrase may sometimes be used of a private order by an employer or other institution. Uses of gag orders include keeping trade secrets of a company, protecting the integrity of ongoing police or military operations, and protecting the privacy of victims or minors. Conversely, as their downside, they may be abused as a useful tool for those of financial means to intimidate witnesses and prevent release of information, using the legal system rather than other methods of intimidation. Strategic lawsuit against public participation (SLAPP) orders may potentially be abused in this way. Gag orders are sometimes used in an attempt to assure a fair trial by preventing prejudicial pre-trial publicity, although their use for this purpose is controversial sin ...

Power Reactor And Nuclear Fuel Development Corporation
The or for short, was a Japanese nuclear energy research organization established 2 October 1967 with the Atomic Fuel Corporation as its parent organization and disbanded in 1998 to be restructured as the Japan Nuclear Cycle Development Institute. The organization specialized in special Breeder reactors and the Advanced Thermal Reactor. It also owned a nuclear reprocessing facility and its activities included uranium exploration in Australia and disposal of high-level waste. Outline In the fast-growing 1960s Japanese business world, domestic reactor technology was mostly undeveloped so importing reactor designs and nuclear fuel proved to be the best economic option. Uranium enrichment technology at the time also had military secrets associated with it, making importing a necessity. Since Japan had very few hydraulic energy resources, breeder reactors and renewable energy were attractive technologies. However, the organization existing at the time to do such research, the Japa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
