SCK CEN
SCK CEN (the Belgian Nuclear Research Centre), until 2020 shortened as SCK•CEN, is the Belgian nuclear research centre located in Mol, Belgium, more specifically near the township of Donk. SCK CEN is a global leader in the field of nuclear research, services, and education. History SCK CEN was founded in 1952 and originally named Studiecentrum voor de Toepassingen van de Kernenergie (Research Centre for the Applications of Nuclear Energy), abbreviated to STK. Land was bought in the municipality of Mol, and over the next years many technical, administrative, medical, and residential buildings were constructed on the site. From 1956 to 1964 four nuclear research reactors became operational: the BR 1, BR 2, BR 3, the first pressurized water reactor in Europe, and VENUS. In 1963 SCK CEN already employed 1600 people, a number that would remain about the same over the next decades. In 1970 SCK CEN widened its field of activities outside the nuclear sector, but the emphasis remai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the Ancient Greece, ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the Cosmogony, origin and Cosmology#Metaphysical cosmology, nature of the world, the lives and activities of List of Greek mythological figures, deities, Greek hero cult, heroes, and List of Greek mythological creatures, mythological creatures, and the origins and significance of the ancient Greeks' own cult (religious practice), cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral tradition, oral-poetic tradition most likely by Minoan civilization, Minoan and Mycenaean Greece, Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its after ...

Hades
Hades (; grc-gre, ᾍδης, Háidēs; ), in the ancient Greek religion and myth, is the god of the dead and the king of the underworld, with which his name became synonymous. Hades was the eldest son of Cronus and Rhea, although this also made him the last son to be regurgitated by his father. He and his brothers, Zeus and Poseidon, defeated their father's generation of gods, the Titans, and claimed rulership over the cosmos. Hades received the underworld, Zeus the sky, and Poseidon the sea, with the solid earth, long the province of Gaia, available to all three concurrently. In artistic depictions, Hades is typically portrayed holding a bident and wearing his helm with Cerberus, the three-headed guard dog of the underworld, standing to his side. The Etruscan god Aita and the Roman gods Dis Pater and Orcus were eventually taken as equivalent to Hades and merged into Pluto, a Latinisation of Plouton ( grc-gre, , Ploútōn), itself a euphemistic title often given to Had ...

Underground Research Laboratory
The Underground Research Laboratory was a test site for deep geological repository of nuclear waste operated by Atomic Energy of Canada Limited's (AECL's) Whiteshell Laboratories near Lac du Bonnet in Manitoba, Canada. The site was built inside a large granite batholith, typical of the Canadian Shield. The site was selected in 1980, construction began in 1982 and it opened in 1985. No radioactive material was stored at the site, it was used purely for measurements of water exchange, rock movement, and other issues that would affect the safety of such materials. The site was also used by a variety of international users. As part of the wider wind-down of AECL activities, the decision was made to close the URL in 2003. Cleanup work began in 2006 and completed in 2010. The site continues to host a single international experiment measuring water leakage through a massive clay plug. History Nuclear Fuel Waste Management Program Through the 1970s the issue of storing nuclear waste became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zero Power Critical
{{Unreferenced, date=August 2009 Zero power critical is a condition of nuclear fission reactors that is useful for characterizing the reactor core. A reactor is in the zero power critical state if it is sustaining a stable fission chain reaction with no significant growth or decay in the reaction rate, and at a low enough level that thermal considerations are not important to the reaction. For example, a reactor that can produce gigawatts of heat might be considered zero-power critical when producing 100 watt The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James ...s of heat through a fission chain reaction. Most nuclear reactors are held at a zero-power critical condition as part of the start-up sequence, to assess the condition of the reactor itself. Nuclear reactors ...

Tihange
Huy ( or ; nl, Hoei, ; wa, Hu) is a city and municipality of Wallonia located in the province of Liège, Belgium. Huy lies along the river Meuse, at the mouth of the small river Hoyoux. It is in the ''sillon industriel'', the former industrial backbone of Wallonia, home to the Walloon population. The municipality consists of the following districts: Ben-Ahin, Huy, Neuville-sous-Huy, and Tihange. History The first village originated around the Roman ''castrum'', an early fortress located on the right bank of the river Meuse. The village was evangelized by Saint Domitian, bishop of Tongeren in the 6th century and the town is mentioned for the first time in a 7th-century testament (as ''Hoius vicus'', taking its name from the river Hoyoux). In the early Middle Ages, Huy was one of the most prosperous cities on the Meuse, with a flourishing economy based mostly on metallurgy, but also on tanning, sculpting, woodworking, and wine-making. In the 10th century, Huy was promoted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doel
Doel is a subdivision of the municipality of Beveren in the Flemish province of East Flanders in Belgium. It is located near the river the Scheldt, in a polder of the Waasland. Since 1965, there have been plans to extend the Port of Antwerp into Doel and demolish the village. However, protests have caused a stalemate. On 30 March 2022, a deal was reached and the village is allowed to exist. History The first mention of the village dates from 1267, when "The Doolen" name is first mentioned. Until the 18th century the village was an island surrounded by purposefully flooded land, with the remainder, north of the village, known as "The Drowned Land of Saeftinghe". The "Eylandt den Doel" is completely surrounded by old seawalls. The dike encloses the hamlets of , "Saftingen", "Rapenburg" and "Ouden Doel" (Olden Doel). The Doel polder site is unique to Belgium and dates back to the Eighty Years War (1568-1648). The typical checkerboard pattern dates from 1614, when these geometric far ...

Pressurised Water Reactor
A pressurized water reactor (PWR) is a type of 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 coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the fission of atoms. The heated, high pressure water then flows to a 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 horizontal steam generators. PWRs were originally designed to serve as nuclear marine ...

Radiopharmacology
Radiopharmacology is radiochemistry applied to medicine and thus the pharmacology of radiopharmaceuticals (medicinal radiocompounds, that is, pharmaceutical drugs that are radioactive). Radiopharmaceuticals are used in the field of nuclear medicine as radioactive tracers in medical imaging and in therapy for many diseases (for example, brachytherapy). Many radiopharmaceuticals use technetium-99m (Tc-99m) which has many useful properties as a gamma-emitting tracer nuclide. In the book ''Technetium'' a total of 31 different radiopharmaceuticals based on Tc-99m are listed for imaging and functional studies of the brain, myocardium, thyroid, lungs, liver, gallbladder, kidneys, skeleton, blood and tumors. The term ''radioisotope'', which in its general sense refers to any radioactive isotope (radionuclide), has historically been used to refer to all radiopharmaceuticals, and this usage remains common. Technically, however, many radiopharmaceuticals incorporate a radioactive tracer a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
