Hanford Nuclear Reservation
The Hanford Site is a decommissioned nuclear production complex operated by the United States federal government on the Columbia River in Benton County, Washington, Benton County in the U.S. state of Washington (state), Washington. The site has been known by many names, including SiteW and the Hanford Nuclear Reservation. Established in 1943 as part of the Manhattan Project, the site was home to the Hanford Engineer Works and B Reactor, the first full-scale plutonium production Nuclear reactor, reactor in the world. Plutonium manufactured at the site was used in the first atomic bomb, which was tested in the Trinity (nuclear test), Trinity nuclear test, and in the Fat Man bomb that was used in the bombing of Nagasaki. During the Cold War, the project expanded to include nine nuclear reactors and five large Nuclear reprocessing, plutonium processing complexes, which produced plutonium for most of the more than sixty thousand weapons built for the Nuclear weapons and the Un ...

Nuclear Technology
Nuclear technology is technology that involves the nuclear reactions of atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is also used, among other things, in smoke detectors and gun sights. History and scientific background Discovery The vast majority of common, natural phenomena on Earth only involve gravity and electromagnetism, and not nuclear reactions. This is because atomic nuclei are generally kept apart because they contain positive electrical charges and therefore repel each other. In 1896, Henri Becquerel was investigating phosphorescence in uranium salts when he discovered a new phenomenon which came to be called radioactivity. He, Pierre Curie and Marie Curie began investigating the phenomenon. In the process, they isolated the element radium, which is highly radioactive. They discovered that radioactive materials produce intense, penetrating rays of three distinct sorts, which they labeled al ...

Yakima River
The Yakima River is a tributary of the Columbia River in south central and eastern Washington state, named for the indigenous Yakama people. Lewis and Clark mention in their journals that the Chin-nâm pam (or the Lower Snake River Chamnapam Nation) called the river ''Tâpe têtt'' (also rendered ''Tapteete''), possibly from the French ''tape-tête'', meaning "head hit". The length of the river from headwaters to mouth is , with an average drop of . It is the longest river entirely in Washington state. Course The river rises in the Cascade Range at an elevation of at Keechelus Dam on Keechelus Lake near Snoqualmie Pass, near Easton. The river flows through that town, skirts Ellensburg, passes the city of Yakima, and continues southeast to Richland, where it flows into the Columbia River creating the Yakima River Delta at an elevation of . About 9 million years ago, the Yakima River flowed south from near Vantage to the Tri-Cities, and then turned west straight for the oc ...

Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hare Lupine
Hares and jackrabbits are mammals belonging to the genus ''Lepus''. They are herbivores, and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears to dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret". A group of hares is called a "husk", a "down" or a "drove". Members of the ''Lepus'' genus are considered true hares, distinguishing them from rabbits which make up the rest of the Leporidae family. However, there are five leporid species with "hare" in their common names which are not considered true hares: the hispid hare (''Caprolagus hispidus''), and four species known as red rock hares (comprising ''Pronolagus''). Conversely, several ''Lepus'' species are called "jackrabbits", but classed as har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LIGO
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. Two large observatories were built in the United States with the aim of detecting gravitational waves by laser interferometry. These observatories use mirrors spaced four kilometers apart which are capable of detecting a change of less than one ten-thousandth the charge diameter of a proton. (that is, to Proxima Centauri at ). The initial LIGO observatories were funded by the United States National Science Foundation (NSF) and were conceived, built and are operated by Caltech and MIT. They collected data from 2002 to 2010 but no gravitational waves were detected. The Advanced LIGO Project to enhance the original LIGO detectors began in 2008 and continues to be supported by the NSF, with important contributions from the United Kingdom's Science ...

Fast Flux Test Facility
The Fast Flux Test Facility (FFTF) is a 400 MW thermal, liquid sodium cooled, nuclear test reactor owned by the U.S. Department of Energy. It does not generate electricity. It is situated in the ''400 Area'' of the Hanford Site, which is located in the state of Washington. History The construction of the FFTF was completed in 1978, and the first reaction took place in 1980. From April 1982 to April 1992 it operated as a national research facility to test various aspects of commercial reactor design and operation, especially relating to breeder reactors. The FFTF is not a breeder reactor itself, but rather a sodium-cooled fast neutron reactor, as the name suggests. It is stated on the site dedicated to the FFTF, that it tested "advanced nuclear fuels, materials, components, nuclear power plant operations and maintenance protocols, and reactor safety designs." By 1993, the number of uses to which the reactor could be put was diminishing, so the decision was taken in December of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
