Lucens Hotel
Lucens () is a municipality in the Broye-Vully district in the canton of Vaud in Switzerland. In 2017 the former municipalities of Brenles, Chesalles-sur-Moudon, Cremin, Forel-sur-Lucens and Sarzens merged into the municipality of Lucens. History Lucens is first mentioned in 964 as ''in villa Losingus''. It was formerly known by the German name ''Losingen''. In 1969 the Lucens reactor, an underground nuclear reactor, began operations. It was a pilot project to test a heavy-water moderated, carbon dioxide gas-cooled reactor. Soon after the initial start up, an undetected blockage in one of the cooling pipes led to a partial fuel meltdown and massive radioactive contamination of the underground site. Following the accident, the reactor was decommissioned and the cavern was then sealed. No humans were irradiated in the accident. Geography After the 2017 merger Lucens had an area of . Before the merger Lucens had an area, (as of the 2004/09 survey) of . Of this area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lucens Reactor
The Lucens reactor was a 6 MW experimental nuclear power reactor built next to Lucens, Vaud, Switzerland. After its connection to the electrical grid on 29 January 1968, the reactor only operated for a few months before it suffered an accident on 21 January 1969. The cause was a corrosion-induced loss of heat dispersal leading to the destruction of a pressure tube which caused an adjacent pressure tube to fail, and partial meltdown of the core, resulting in radioactive contamination of the cavern. Description In 1962 the construction of a Swiss-designed pilot nuclear power plant began. The heavy-water moderated, carbon dioxide gas-cooled reactor was built in a cavern. It produced 28 MW of heat, which was used to generate 6 MW of electricity, and it became critical 29 December 1966. It was fueled by 0.96% enriched uranium alloyed with chromium cased in magnesium alloy (magnesium with 0.6% zirconium) inserted into a graphite matrix. Carbon dioxide gas was pum ...

Coat Of Arms
A coat of arms is a heraldic visual design on an escutcheon (i.e., shield), surcoat, or tabard (the latter two being outer garments). The coat of arms on an escutcheon forms the central element of the full heraldic achievement, which in its whole consists of a shield, supporters, a crest, and a motto. A coat of arms is traditionally unique to an individual person, family, state, organization, school or corporation. The term itself of 'coat of arms' describing in modern times just the heraldic design, originates from the description of the entire medieval chainmail 'surcoat' garment used in combat or preparation for the latter. Rolls of arms are collections of many coats of arms, and since the early Modern Age centuries, they have been a source of information for public showing and tracing the membership of a noble family, and therefore its genealogy across time. History Heraldic designs came into general use among European nobility in the 12th century. Sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blazon
In heraldry and heraldic vexillology, a blazon is a formal description of a coat of arms, flag or similar emblem, from which the reader can reconstruct the appropriate image. The verb ''to blazon'' means to create such a description. The visual depiction of a coat of arms or flag has traditionally had considerable latitude in design, but a verbal blazon specifies the essentially distinctive elements. A coat of arms or flag is therefore primarily defined not by a picture but rather by the wording of its blazon (though in modern usage flags are often additionally and more precisely defined using geometrical specifications). ''Blazon'' is also the specialized language in which a blazon is written, and, as a verb, the act of writing such a description. ''Blazonry'' is the art, craft or practice of creating a blazon. The language employed in ''blazonry'' has its own vocabulary, grammar and syntax, which becomes essential for comprehension when blazoning a complex coat of arms. Other ...

Broye
The Broye (; frp, Brouye''Dictionnaire-Dikchenéro: Français-Patois/Patê-Franché''. Société cantonale des patoisans fribourgeois. Fribourg: 2013. p. 87 ) is a 68 km long river, in the cantons of Fribourg and Vaud, in Switzerland. It has a watershed area of 850 km². Presentation Its source is located in Semsales, in the Fribourgeois/Vaudois Prealps, south-west of Bulle. It flows first south-west along the Fribourgeois/Vaudois Prealps and turns north after 10 km. The direction of the river changes again near Moudon to the north-east. From Payerne, the Broye is running in a large and agricultural valley. The river flows into Lake Morat first, and then into Lake Neuchâtel through the ''Broye canal'' (French: ''Canal de la Broye'').

Château De Lucens Et Le Bourg
A château (; plural: châteaux) is a manor house or residence of the lord of the manor, or a fine country house of nobility or gentry, with or without fortifications, originally, and still most frequently, in French-speaking regions. Nowadays a ''château'' may be any stately residence built in a French style; the term is additionally often used for a winegrower's estate, especially in the Bordeaux region of France. Definition The word château is a French word that has entered the English language, where its meaning is more specific than it is in French. The French word ''château'' denotes buildings as diverse as a medieval fortress, a Renaissance palace and a fine 19th-century country house. Care should therefore be taken when translating the French word ''château'' into English, noting the nature of the building in question. Most French châteaux are "palaces" or fine " country houses" rather than "castles", and for these, the word "château" is appropriate in E ...

Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants, produces ionizing radiation (namely alpha, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge ...

Nuclear Meltdown
A nuclear meltdown (core meltdown, core melt accident, meltdown or partial core melt) is a severe nuclear reactor accident that results in core damage from overheating. The term ''nuclear meltdown'' is not officially defined by the International Atomic Energy Agency or by the United States Nuclear Regulatory Commission. It has been defined to mean the accidental melting of the core of a nuclear reactor, however, and is in common usage a reference to the core's either complete or partial collapse. A core meltdown accident occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point where at least one nuclear fuel element exceeds its melting point. This differs from a fuel element failure, which is not caused by high temperatures. A meltdown may be caused by a loss of coolant, loss of coolant pressure, or low coolant flow rate or be the result of a criticality excursion in which the reactor is operated at a power level t ...

Gas-cooled Reactor Types
A gas-cooled reactor (GCR) is a nuclear reactor that uses graphite as a neutron moderator and a gas (carbon dioxide or helium in extant designs) as coolant. Although there are many other types of reactor cooled by gas, the terms ''GCR'' and to a lesser extent ''gas cooled reactor'' are particularly used to refer to this type of reactor. The GCR was able to use natural uranium as fuel, enabling the countries that developed them to fabricate their own fuel without relying on other countries for supplies of enriched uranium, which was at the time of their development in the 1950s only available from the United States or the Soviet Union. The Canadian CANDU reactor, using heavy water as a moderator, was designed with the same goal of using natural uranium fuel for similar reasons. Design considerations Historically thermal spectrum graphite moderated gas cooled reactors mostly competed with light water reactors, ultimately losing out to them after having seen some deployment in Bri ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.
