Repository For Radioactive Waste Morsleben
The Morsleben Radioactive Waste Repository (German: Endlager für radioaktive Abfälle Morsleben-ERAM) is a deep geological repository for radioactive waste in the Bartensleben rock salt mine in Morsleben, Landkreis Börde, Börde District, in the federal state of Saxony-Anhalt, Germany. History After closure of the salt mining activities, Bartensleben was designated as a repository for radioactive waste by the former government of East Germany. Today, the shaft is operated by the Deutsche Gesellschaft zum Bau und Betrieb von Endlagern für Abfallstoffe mbH (DBE) under supervision of the Bundesamt für Strahlenschutz. Potash The salt mining industry in this region is over a century old, beginning with the first potash mining shaft, "Marie", in 1897. The "Bartensleben" shaft started between 1910–1912 and is currently 525m deep. The mine levels in "Bartensleben" are interconnected with "Marie" at depths 326, 426, 466 and 506 m. The main mine structure is between 320 and 630m dept ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed (German for "Swallow") in fighter versions, or ("Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational jet-powered fighter aircraft and one of two jet fighter aircraft types to see air-to-air combat in World War Two, the other being the Heinkel He 162. The design of what would become the Me 262 started in April 1939, before World War II. It made its maiden flight on 18 April 1941 with a piston engine, and its first jet-powered flight on 18 July 1942.

German Reunification
German reunification () was the process of re-establishing Germany as a single sovereign state, which began on 9 November 1989 and culminated on 3 October 1990 with the dissolution of the East Germany, German Democratic Republic and the integration of its re-established constituent federated states into the West Germany, Federal Republic of Germany to form Germany, present-day Germany. This date was chosen as the customary German Unity Day, and has thereafter been celebrated each year as a national day, national holiday. On the same date, East Berlin, East and West Berlin, West Berlin were also reunified into a single city, which eventually Decision on the Capital of Germany, became the capital of Germany. The East German government, controlled by the Socialist Unity Party of Germany (SED), started to falter on 2 May 1989, when the removal of Hungary's border fence with Austria opened a hole in the Iron Curtain. The border was still closely guarded, but the Pan-European Picn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radionuclides
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess numbers of either neutrons or protons, giving it excess nuclear energy, and making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle (alpha particle or beta particle) from the nucleus. During those processes, the radionuclide is said to undergo radioactive decay. These emissions are considered ionizing radiation because they are energetic enough to liberate an electron from another atom. The radioactive decay can produce a stable nuclide or will sometimes produce a new unstable radionuclide which may undergo further decay. Radioactive decay is a random process at the level of single atoms: it is impossible to predict when one particular atom will decay. However, for a collection of atoms of a single nucl ...

Forschungszentrum Dresden-Rossendorf
The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is a Dresden-based research laboratory. It conducts research in three of the Helmholtz Association's areas: materials, health, and energy. HZDR is a member of the Helmholtz Association of German Research Centres. History HZDR is located at the site of the former Central Institute for Nuclear Physics (later: Central Institute for Nuclear Research) in Dresden-Rossendorf, which was founded in 1956 and became the largest nuclear research institute in the GDR. The former research center in Rossendorf was part of the German Academy of Sciences. The German-born British physicist Klaus Fuchs, who took part in the Manhattan Project and acted as a spy for the Soviet Union, was deputy director until 1974. In 1992, Forschungszentrum Rossendorf was founded at the research site. In 2006 the name changed to "Forschungszentrum Dresden-Rossendorf", to emphasize the connection to the research infrastructure in the city of Dresden. In 2011 the ce ...

ELBE
The Elbe ( ; ; or ''Elv''; Upper Sorbian, Upper and , ) is one of the major rivers of Central Europe. It rises in the Giant Mountains of the northern Czech Republic before traversing much of Bohemia (western half of the Czech Republic), then Germany and flowing into the North Sea at Cuxhaven, northwest of Hamburg. Its total length is . The Elbe's major Tributary, tributaries include the rivers Vltava, Ohře, Saale, Havel, Mulde, and Schwarze Elster. The Elbe river basin, comprising the Elbe and its tributaries, has a catchment area of , the twelfth largest in Europe. The basin spans four countries; however, it lies almost entirely just in two of them, Germany (65.5%) and the Czech Republic (33.7%, covering about two thirds of the nation's territory). On its southeastern edges, the Elbe river basin also comprises small parts of Austria (0.6%) and Poland (0.2%). The Elbe catchment area is inhabited by 24.4 million people; its biggest cities are Berlin, Hamburg, Prague, Dresden a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheinsberg Nuclear Power Plant
Rheinsberg Nuclear Power Station (, KKR) was the second nuclear reactor in East Germany after the Rossendorf Research Reactor, and the first nuclear power reactor in East Germany. It was built close to the city of Rheinsberg on the Stechlinsee. The power station was one of the first generation of demonstration power reactors. Start-up The project commenced in 1956, and construction began January 1, 1960. First criticality followed on March 11, 1966 (the reactor was not pressurised at that time however). Full start-up was on May 9, and commercial power production began on October 11, 1966. Achievement The single pressurized water reactor was of Soviet design – type VVER-210. Gross power of the station was 70 MWe, but 8 MWe was required to run plant systems, so net output to the grid was 62 MWe. Gross power output was subsequently raised to 75 MWe and then 80 MWe as operating experience increased. Cooling water was taken from the Nehmitzsee and by a special discharge channe ...

Greifswald Nuclear Power Plant
Greifswald nuclear power station (German: ''Kernkraftwerk Greifswald'', KKW Greifswald), also known as Lubmin nuclear power station, was the largest nuclear power station in East Germany before closure shortly after the German reunification. The plants were of the VVER-440/V-230 type, which was the second generation of Soviet-designed plants. The plant is in Lubmin near Greifswald, in the state of Mecklenburg-Vorpommern. The plant provided roughly one third of East Germany's energy needs singlehandedly. As of 2024, around 1000 workers continue to work on the site 35 years later for decommissioning purposes. Closure In late 1989, nuclear regulatory bodies of countries operating VVER plants found the need to fit many new safety systems, which were stated to have been necessary in almost all areas. All East German reactors were closed soon after reunification, with restarting conditional on compliance with the stricter West German safety standards. Convinced that upgrading to ...

Becquerel
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as an activity of one per second, on average, for aperiodic activity events referred to a radionuclide. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 μs would mean 10 disintegrations per second: , whereas 1 μBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second (for ''periodic'' events of any kind), and fourier (Fr; after ...

Low Level Radioactive Waste
Low-level waste (LLW) or low-level radioactive waste (LLRW) is a category of nuclear waste. The definition of low-level waste is set by the nuclear regulators of individual countries, though the International Atomic Energy Agency (IAEA) provides recommendations. LLW includes items that have become contaminated with radioactive material or have become radioactive through exposure to neutron radiation. This waste typically consists of contaminated protective shoe covers and clothing, wiping rags, mops, filters, reactor water treatment residues, equipments and tools, luminous dials, medical tubes, swabs, injection needles, syringes, and laboratory animal carcasses and tissues. LLW in the United Kingdom In the UK, LLW is defined as waste with specific activities below 12 gigabecquerel/ tonne (GBq/t) beta/gamma and below 4 GBq/t alpha emitting nuclides. Waste with specific activities above these thresholds are categorised as either Intermediate-level waste (ILW) or high heat gene ...
