EGP-6
The EGP-6 is a Russian small nuclear reactor design. It is a scaled down version of the RBMK design. As the RBMK, the EGP-6 uses water for cooling and graphite as a neutron moderator. EGP is a Russian acronym but translated into English stand for Power Heterogenous Loop reactor. It is the world's smallest running commercial nuclear reactor, however smaller reactors are currently in development. The EGP-6 reactors are the only reactors to be built on perma-frost. There were only four EGP-6 reactors built which formed the Bilibino Nuclear Power Plant, commissioned in 1974-1977, with a reactor becoming operational each year. The reactors were responsible for supplying Bilibino with utilities such as electricity, heated water, and steam. The population of Bilibino currently sits at around 5,000 and a large majority of its citizens are associated with the plant. The plant design was developed by the Ural Division of Teploelektroproekt together with Izhorskiye Zavody and FEI in Obnin ...

Bilibino Nuclear Power Plant
The Bilibino Nuclear Power Plant (russian: Билибинская АЭС []) is a Power station, power plant in Bilibino, Chukotka Autonomous Okrug, Russia. The plant is equipped with four EGP-6 reactors. The plant is the smallest and the second northernmost operating nuclear power plant in the world. Plans to begin a shutdown procedure of the plant in 2019 have been announced, and it will be replaced by the floating nuclear power station ''Akademik Lomonosov''. Radiation exposure As of 2012, the EGP-6 reactors at the plant exposed personnel and staff on average to 3.7 mSv/year. This makes up 18.5% of the 20 mSv/year designated radiation workers can receive. The exposure by the Bilibino Nuclear Power Plant is higher than the average for Russian nuclear power plants which sits at 1.26 mSv/year. Improvements since the Fukushima-Daiichi accident Following the 2011 Fukushima nuclear disaster, measures were taken to ensure safety and emergency responses for Russian nuclear power ...

RBMK
The RBMK (russian: реактор большой мощности канальный, РБМК; ''reaktor bolshoy moshchnosti kanalnyy'', "high-power channel-type reactor") is a class of graphite-moderated nuclear power reactor designed and built by the Soviet Union. The name refers to its design where, instead of a large steel pressure vessel surrounding the entire core, the core is surrounded by a cylindrical annular steel tank inside a concrete vault and each fuel assembly is enclosed in an individual 8 cm (inner) diameter pipe (called a "technological channel"). The channels also contain the coolant, and are surrounded by graphite. The RBMK is an early Generation II reactor and the oldest commercial reactor design still in wide operation. Certain aspects of the original RBMK reactor design, such as the large positive void coefficient, the 'positive scram effect' of the control rods and instability at low power levels, contributed to the 1986 Chernobyl disaster, in which ...

Graphite Moderated Reactors
:''"Graphite reactor" directs here. For the graphite reactor at Oak Ridge National Laboratory, see X-10 Graphite Reactor.'' A graphite-moderated reactor is a nuclear reactor that uses carbon as a neutron moderator, which allows natural uranium to be used as nuclear fuel. The first artificial nuclear reactor, the Chicago Pile-1, used nuclear graphite as a moderator. Graphite-moderated reactors were involved in two of the best-known nuclear disasters: an untested graphite annealing process contributed to the Windscale fire (but the graphite itself did not catch fire), while a graphite fire during the Chernobyl disaster contributed to the spread of radioactive material. Types Several types of graphite-moderated nuclear reactors have been used in commercial electricity generation: *Gas-cooled reactors **Magnox **UNGG reactor ** Advanced gas-cooled reactor (AGR) *Water-cooled reactors **RBMK **MKER **EGP-6 *High-temperature gas-cooled reactors (past) **Dragon reactor ** AVR **Pea ...

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

Neutron Moderator
In nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy. These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium-235 or other fissile isotope by colliding with their atomic nucleus. Water (sometimes called "light water" in this context) is the most commonly used moderator (roughly 75% of the world's reactors). Solid graphite (20% of reactors) and heavy water (5% of reactors) are the main alternatives. Beryllium has also been used in some experimental types, and hydrocarbons have been suggested as another possibility. Moderation Neutrons are normally bound into an atomic nucleus, and do not exist free for long in nature. The unbound neutron has a half-life of 10 minutes and 11 seconds. The release of neutrons from the nucleus requires exceeding the binding energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global war ...
