Grohnde Nuclear Power Plant
The former Grohnde Nuclear Power Plant is located in Grohnde in the Hamelin-Pyrmont district in Lower Saxony. It had one reactor that used 193 fuel assemblies and utilized both enriched uranium and MOX fuel. In 1985, 1986, 1987, 1989, 1990 and 1998 the reactor produced more net electricity for the respective year than any other reactor in the world. The plant was of the pressurized water reactor type, using four water based coolant cycles, kept under high pressure. In 2021 the plan passed the mark of 400 TWh total low-carbon A low-carbon economy (LCE) or decarbonised economy is an economy based on energy sources that produce low levels of greenhouse gas (GHG) emissions.

Weser
The Weser () is a river of Lower Saxony in north-west Germany. It begins at Hannoversch Münden through the confluence of the Werra and Fulda. It passes through the Hanseatic city of Bremen. Its mouth is further north against the ports of Bremerhaven and Nordenham. The latter is on the Butjadingen Peninsula. It then merges into the North Sea via two highly saline, estuarine mouths. It connects to the canal network running east-west across the North German Plain. The river, when combined with the Werra (a dialectal form of "Weser"), is long and thus, the longest river entirely situated within Germany (the Main, however, is the longest if the Weser and Werra are not combined). The Weser itself is long. The Werra rises in Thuringia, the German state south of the main projection (tongue) of Lower Saxony. Etymology "Weser" and "Werra" are the same words in different dialects. The difference reflects the old linguistic border between Central and Low German, passing through H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grohnde
Emmerthal is a municipality in the Hameln-Pyrmont district, in Lower Saxony, Germany. It is situated on the river Weser, approximatively 6 km south of Hameln. Its seat is in the village Kirchohsen. In 1973, the Emmerthal was formed by merging the previously independent municipalities of Amelgatzen, Bessinghausen, Börry, Brockensen, Emmern, Esperde, Frenke, Grohnde, Hagenohsen, Hajen, Hämelschenburg, Kirchohsen, Latferde, Lüntorf, Ohr, Voremberg, Welsede. The Grohnde Nuclear Power Plant is located in the Emmerthal. From 1933 to 1937, the National Socialists held their national thanksgiving festival in a field on the nearby Bückeberg The Bückeberg (; also the Bückeberge) is a small hill range, up to high, in the Calenberg Uplands between the Harrl and the Deister in central Germany, and is often considered part of the Weser Uplands.

Hamelin-Pyrmont
Hameln-Pyrmont is a district (''Landkreis'') in Lower Saxony, Germany. It is bounded by (from the north and clockwise) the districts of Schaumburg, Hanover, Hildesheim and Holzminden, and by the state of North Rhine-Westphalia (district of Lippe). History A district called Hameln was established in 1885 within the Prussian Province of Hanover. At that time the city of Pyrmont was part of the Principality of Waldeck-Pyrmont. In 1921 Pyrmont decided in a plebiscite to leave Waldeck-Pyrmont and to join Prussia. The Prussian administration assigned the city to the district of Hameln, which was renamed to Hameln-Pyrmont. In 1923 Hameln became a district-free city and was not part of the district until 1973, when it was reincorporated. Further enlargements of the district's territory took place in 1974 and 1977, when the cities of Bad Münder and Hessisch Oldendorf joined the district. Geography The district is located in the northern part of the Weserbergland mountains. The Weser Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Saxony
Lower Saxony (german: Niedersachsen ; nds, Neddersassen; stq, Läichsaksen) is a German state (') in northwestern Germany. It is the second-largest state by land area, with , and fourth-largest in population (8 million in 2021) among the 16 ' federated as the Federal Republic of Germany. In rural areas, Northern Low Saxon and Saterland Frisian are still spoken, albeit in declining numbers. Lower Saxony borders on (from north and clockwise) the North Sea, the states of Schleswig-Holstein, Hamburg, , Brandenburg, Saxony-Anhalt, Thuringia, Hesse and North Rhine-Westphalia, and the Netherlands. Furthermore, the state of Bremen forms two enclaves within Lower Saxony, one being the city of Bremen, the other its seaport, Bremerhaven (which is a semi-enclave, as it has a coastline). Lower Saxony thus borders more neighbours than any other single '. The state's largest cities are state capital Hanover, Braunschweig (Brunswick), Lüneburg, Osnabrück, Oldenburg, Hildesheim, Salzgitt ...

Enriched Uranium
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%). 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation. There are about 2,000 tonnes of highly enriched uranium in the world, produced mostly for nuclear power, nuclear weapons, naval propulsion, and smaller quantities for research reactors ...

MOX Fuel
Mixed oxide fuel, commonly referred to as MOX fuel, is nuclear fuel that contains more than one oxide of fissile material, usually consisting of plutonium blended with natural uranium, reprocessed uranium, or depleted uranium. MOX fuel is an alternative to the low-enriched uranium (LEU) fuel used in the light-water reactors that predominate nuclear power generation. For example, a mixture of 7% plutonium and 93% natural uranium reacts similarly, although not identically, to LEU fuel (3 to 5% uranium-235). MOX usually consists of two phases, UO2 and PuO2, and/or a single phase solid solution (U,Pu)O2. The content of PuO2 may vary from 1.5 wt.% to 25–30 wt.% depending on the type of nuclear reactor. One attraction of MOX fuel is that it is a way of utilizing surplus weapons-grade nuclear material, weapons-grade plutonium, an alternative to storage of surplus plutonium, which would need to be secured against the risk of theft for use in nuclear weapons. On the other hand, some st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

Low-carbon Power
Low-carbon power is electricity produced with substantially lower greenhouse gas emissions than conventional fossil fuel power generation. The energy transition to low-carbon power is one of the most important actions required to limit climate change. Power sector emissions may have peaked in 2018. During the first six months of 2020, scientists observed an 8.8% decrease in global CO2 emissions relative to 2019 due to COVID-19 lockdown measures. The two main sources of the decrease in emissions included ground transportation (40%) and the power sector (22%). This event is the largest absolute decrease in CO2 emissions in history, but emphasizes that low-carbon power "must be based on structural and transformational changes in energy-production systems". Low carbon power generation sources include wind power, solar power, nuclear power and most hydropower. The term largely excludes conventional fossil fuel plant sources, and is only used to describe a particular subset of oper ...

Former Nuclear Power Stations In Germany
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...
