The second half of the 20th century was marked by rising tensions between the Dutch-speakers and French-speakers, fueled by differences in political culture and the unequal economic development of Flanders and Wallonia. This continuing antagonism has led to several far-reaching state reforms , resulting in
2067-460: A particular air temperature. How much water vapor a parcel of air can contain before it becomes saturated (100% relative humidity) and forms into a cloud (a group of visible tiny water or ice particles suspended above the Earth's surface) depends on its temperature. Warmer air can contain more water vapor than cooler air before becoming saturated. Therefore, one way to saturate a parcel of air

2862-407: A result of this warming, monthly rainfall is about 28% greater between 32 and 64 km (20 and 40 mi) downwind of cities, compared with upwind. Some cities induce a total precipitation increase of 51%. Increasing temperatures tend to increase evaporation which can lead to more precipitation. Precipitation generally increased over land north of 30°N from 1900 through 2005 but has declined over
3021-649: A teardrop. The biggest raindrops on Earth were recorded over Brazil and the Marshall Islands in 2004 — some of them were as large as 10 mm (0.39 in). The large size is explained by condensation on large smoke particles or by collisions between drops in small regions with particularly high content of liquid water. Raindrops associated with melting hail tend to be larger than other raindrops. Intensity and duration of rainfall are usually inversely related, i.e., high-intensity storms are likely to be of short duration and low-intensity storms can have

Humid subtropical climates lie on the east side continents, roughly between latitudes 20° and 40° degrees away from the equator. An oceanic (or maritime) climate is typically found along the west coasts at the middle latitudes of all the world's continents, bordering cool oceans, as well as southeastern Australia, and
11766-670: The 19th century were the Catholic Party and the Liberal Party , with the Belgian Labour Party emerging towards the end of the 19th century. French was originally the official language used by the nobility and the bourgeoisie , especially after the rejection of the Dutch monarchy. French progressively lost its dominance as Dutch began to recover its status. This recognition became official in 1898, and in 1967,
11925-744: The Ardennes are more rugged and rocky with caves and small gorges . Extending westward into France, this area is eastwardly connected to the Eifel in Germany by the High Fens plateau, on which the Signal de Botrange forms the country's highest point at 694 m (2,277 ft). The climate is maritime temperate with significant precipitation in all seasons ( Köppen climate classification : Cfb ), like most of northwest Europe. The average temperature
12084-581: The Belgian Federal government placed a moratorium on the reprocessing activities in order to research other options. Pending further decisions regarding this moratorium, spent fuel is stored on site in spent fuel pools . Final disposal of the waste is being researched at the HADES underground laboratory 225m deep in the Boom Clay. Nuclear transmutation of the waste is also being researched with
12243-607: The Belgian state to assume responsibility for the government of the colony, henceforth called the Belgian Congo . A Belgian commission in 1919 estimated that Congo's population was half what it was in 1879. Germany invaded Belgium in August 1914 as part of the Schlieffen Plan to attack France , and much of the Western Front fighting of World War I occurred in western parts of the country. The opening months of
12402-675: The Communities and Regions were created in 1980, Flemish politicians decided to merge both. Thus the Flemings just have one single institutional body of parliament and government is empowered for all except federal and specific municipal matters. The overlapping boundaries of the Regions and Communities have created two notable peculiarities: the territory of the Brussels-Capital Region (which came into existence nearly
12561-759: The County of Flanders and it became one of the richest areas in Europe. This prosperity played a role in conflicts between Flanders and the king of France . Famously, Flemish militias scored a surprise victory at the Battle of the Golden Spurs against a strong force of mounted knights in 1302, but France soon regained control of the rebellious province. In the 15th century, the Duke of Burgundy in France took control of Flanders, and from there proceeded to unite much of what
12720-461: The EPA's lifetime drinking water health advisories as well as comparable Danish, Dutch, and European Union safety standards, leading to the conclusion that "the global spread of these four PFAAs in the atmosphere has led to the planetary boundary for chemical pollution being exceeded". It had been thought that PFAAs would eventually end up in the oceans, where they would be diluted over decades, but
12879-404: The Earth's atmosphere which form clouds decks such as altostratus or cirrostratus . Stratus is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass. It can also form due to the lifting of advection fog during breezy conditions. Coalescence occurs when water droplets fuse to create larger water droplets. Air resistance typically causes
13038-503: The Engie Top-woman Isabelle Kocher: 'On the safety of our people, of the people living near the power plants and the environment is not to bargain.' In the action plan the responsibilities were more clearly defined and the company was willing to will appeal more independent expertise. The action plan includes a total of 314 actions, of which 142 were already carried out. The intention was that around August 2017
13197-620: The European Parliament Rebecca Harms has called for the decommissioning of Belgium's oldest nuclear reactor, Tihange 1, as it no longer meets international safety standards. Harms’ demand coincides with the publication of a new study on the risks of the continued operation of Tihange 1. The author of the study is Prof. Manfred Mertins, an expert in nuclear engineering and former member of the German Nuclear Safety Authority. He presented
13356-610: The European Union, for which Belgium hosts major administrations and institutions, including the European Commission , the Council of the European Union and the extraordinary and committee sessions of the European Parliament . In the early 1990s, Belgium saw several large corruption scandals notably surrounding Marc Dutroux , Andre Cools , the Dioxin Affair , Agusta Scandal and the murder of Karel van Noppen . Belgium shares borders with France ( 620 km ), Germany ( 162/167 km ), Luxembourg ( 148 km ), and
13515-491: The Flemings refused to do so and succeeded progressively in making Dutch an equal language in the education system. Following World War II, Belgian politics became increasingly dominated by the autonomy of its two main linguistic communities. Intercommunal tensions rose and the constitution was amended to minimize the potential for conflict. Based on the four language areas defined in 1962–63 (the Dutch, bilingual, French and German language areas), consecutive revisions of
13674-678: The Internet, such as CoCoRAHS or GLOBE. If a network is not available in the area where one lives, the nearest local weather or met office will likely be interested in the measurement. One of the main uses of weather radar is to be able to assess the amount of precipitations fallen over large basins for hydrological purposes. For instance, river flood control , sewer management and dam construction are all areas where planners use rainfall accumulation data. Radar-derived rainfall estimates complement surface station data which can be used for calibration. To produce radar accumulations, rain rates over
13833-505: The Latin name of a large Roman province covering most of Northern Gaul, including the Belgae and Treveri. However, areas closer to the lower Rhine frontier, including the eastern part of modern Belgium, subsequently became part of the frontier province of Germania Inferior , which continued to interact with their neighbours outside the empire. At the time when central government collapsed in
13992-564: The N-VA remained the largest party in parliament. In July 2019 prime minister Charles Michel was selected to hold the post of President of the European Council . His successor Sophie Wilmès was Belgium's first female prime minister. She led the caretaker government since October 2019. The Flemish Liberal party politician Alexander De Croo became new prime minister in October 2020. The parties had agreed on federal government 16 months after
14151-889: The Northeast and Midwest, which in the past decade, have seen 31 and 16 percent more heavy downpours compared to the 1950s. Rhode Island is the state with the largest increase, 104%. McAllen, Texas is the city with the largest increase, 700%. Heavy downpour in the analysis are the days where total precipitation exceeded the top one percent of all rain and snow days during the years 1950–2014. The most successful attempts at influencing weather involve cloud seeding , which include techniques used to increase winter precipitation over mountains and suppress hail . Rainbands are cloud and precipitation areas which are significantly elongated. Rainbands can be stratiform or convective , and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation
14310-545: The Regions' and Communities' Governments is the broadest of all the Federating units of all the Federations all over the world. Because of its location at the crossroads of Western Europe , Belgium has historically been the route of invading armies from its larger neighbors. With virtually defenseless borders, Belgium has traditionally sought to avoid domination by the more powerful nations which surround it through
14469-421: The action plan was to be completed. In September 2018 during a planned inspection by the exploitant Engie Electrabel decaying concrete was found in the bunker-buildings of Doel 3 and Tihange 3, where the emergency-systems are located. Only after further investigations and when FANC gives permission will the reactors be restarted. According to FANC the decay of the concrete had no impact on the direct environment of
14628-405: The atmosphere exceeds 3,400 m (11,000 ft) above ground level. Convective rain , or showery precipitation, occurs from convective clouds (e.g., cumulonimbus or cumulus congestus ). It falls as showers with rapidly changing intensity. Convective precipitation falls over a certain area for a relatively short time, as convective clouds have limited horizontal extent. Most precipitation in
14787-399: The cabinet to the king, as no progress in constitutional reforms had been made. In December 2008, Leterme once more offered his resignation after a crisis surrounding the sale of Fortis to BNP Paribas . At this juncture, his resignation was accepted and Christian Democratic and Flemish Herman Van Rompuy was sworn in as Prime Minister on 30 December 2008. After Herman Van Rompuy
14946-482: The chimney of Unit 1 is 161.18 metres, that of Unit 2 161.21 metres and that of Unit 3 160.79 metres. Low and intermediate level waste, which represents 99% of the volume of waste, is treated on site. Category A waste with half lives of less than 30 years is transported to Belgoprocess in Dessel for surface disposal. High level waste was originally recycled to MOX fuel , and re-used in the Tihange 2 reactor. In 1993,
15105-731: The civil servants. Communities exercise their authority only within linguistically determined geographical boundaries, originally oriented towards the individuals of a Community's language: culture (including audiovisual media), education and the use of the relevant language. Extensions to personal matters less directly connected with language comprise health policy (curative and preventive medicine) and assistance to individuals (protection of youth, social welfare, aid to families, immigrant assistance services, and so on.). Regions have authority in fields that can be broadly associated with their territory. These include economy, employment, agriculture, water policy, housing, public works, energy, transport,
15264-517: The concentrations of nitric and sulfuric acid has decreased in presence of rainwater, which may be due to the significant increase in ammonium (most likely as ammonia from livestock production), which acts as a buffer in acid rain and raises the pH. The Köppen classification depends on average monthly values of temperature and precipitation. The most commonly used form of the Köppen classification has five primary types labeled A through E. Specifically,
15423-612: The contiguous United States, total annual precipitation increased at an average rate of 6.1 percent since 1900, with the greatest increases within the East North Central climate region (11.6 percent per century) and the South (11.1 percent). Hawaii was the only region to show a decrease (−9.25 percent). Analysis of 65 years of United States of America rainfall records show the lower 48 states have an increase in heavy downpours since 1950. The largest increases are in
15582-574: The country in May 1940 , and 40,690 Belgians, over half of them Jews, were killed during the subsequent occupation and the Holocaust . From September 1944 to February 1945 the Allies liberated Belgium. After World War II , a general strike forced King Leopold III to abdicate in 1951 in favour of his son, Prince Baudouin , since many Belgians thought he had collaborated with Germany during
15741-535: The country to be 160 km (62 sq mi) larger in surface area than previously thought. Its land area alone is 30,494 square kilometers. It lies between latitudes 49°30' and 51°30' N, and longitudes 2°33' and 6°24' E. Belgium has three main geographical regions; the coastal plain in the northwest and the central plateau both belong to the Anglo-Belgian Basin, and the Ardennes uplands in
15900-407: The country's constitution in 1970, 1980, 1988 and 1993 established a unique form of a federal state with segregated political power into three levels: The constitutional language areas determine the official languages in their municipalities, as well as the geographical limits of the empowered institutions for specific matters. Although this would allow for seven parliaments and governments when
16059-710: The course of the week, the likelihood of rain increases: it peaks by Saturday, after five days of weekday pollution has been built up. In heavily populated areas that are near the coast, such as the United States' Eastern Seaboard , the effect can be dramatic: there is a 22% higher chance of rain on Saturdays than on Mondays. The urban heat island effect warms cities 0.6 to 5.6 °C (33.1 to 42.1 °F) above surrounding suburbs and rural areas. This extra heat leads to greater upward motion, which can induce additional shower and thunderstorm activity. Rainfall rates downwind of cities are increased between 48% and 116%. Partly as
16218-412: The crystal and neighboring water droplets. This process is temperature dependent, as supercooled water droplets only exist in a cloud that is below freezing. In addition, because of the great temperature difference between cloud and ground level, these ice crystals may melt as they fall and become rain. Raindrops have sizes ranging from 0.1 to 9 mm (0.0039 to 0.3543 in) mean diameter but develop
16377-559: The descending and generally warming, leeward side where a rain shadow is observed. In Hawaii , Mount Waiʻaleʻale , on the island of Kauai, is notable for its extreme rainfall, as it is amongst the places in the world with the highest levels of rainfall, with 9,500 mm (373 in). Systems known as Kona storms affect the state with heavy rains between October and April. Local climates vary considerably on each island due to their topography, divisible into windward ( Koʻolau ) and leeward ( Kona ) regions based upon location relative to
16536-647: The elections. Following a usage which can be traced back to the Burgundian and Habsburg courts, in the 19th century it was necessary to speak French to belong to the governing upper class, and those who could only speak Dutch were effectively second-class citizens. Late that century, and continuing into the 20th century, Flemish movements evolved to counter this situation. While the people in Southern Belgium spoke French or dialects of French, and most Brusselers adopted French as their first language,
16695-621: The environment, town and country planning, nature conservation, credit and foreign trade. They supervise the provinces, municipalities and intercommunal utility companies. In several fields, the different levels each have their own say on specifics. With education, for instance, the autonomy of the Communities neither includes decisions about the compulsory aspect nor allows for setting minimum requirements for awarding qualifications, which remain federal matters. Each level of government can be involved in scientific research and international relations associated with its powers. The treaty-making power of
16854-546: The findings at a news briefing in the European Parliament. The academic came to the conclusion that the continued operation of Tihange 1 due to “outdated reactor design, inadequate safety management and the accumulation of frequent unplanned events represents a potential danger for the site and its surroundings.” It was particularly critical “that the results of international tests and current safety standards are not adequately taken into account.” On 15 March 2016,
17013-511: The formation of a low-level barrier jet . Bands of thunderstorms can form with sea breeze and land breeze boundaries if enough moisture is present. If sea breeze rainbands become active enough just ahead of a cold front, they can mask the location of the cold front itself. Once a cyclone occludes an occluded front (a trough of warm air aloft) will be caused by strong southerly winds on its eastern periphery rotating aloft around its northeast, and ultimately northwestern, periphery (also termed
17172-795: The four components are subordinate to the Staff Department for Operations and Training of the Ministry of Defense , which is headed by the Assistant Chief of Staff Operations and Training , and to the Chief of Defense . The Belgian military consists of volunteers (conscription was abolished in 1995), and citizens of other EU states, Iceland, Norway, Switzerland, or Lichtenstein are also able to join. Belgium has troops deployed in several African countries as part of UN or EU missions, in Iraq for
17331-482: The front is unstable enough for convection. Banding within the comma head precipitation pattern of an extratropical cyclone can yield significant amounts of rain. Behind extratropical cyclones during fall and winter, rainbands can form downwind of relative warm bodies of water such as the Great Lakes . Downwind of islands, bands of showers and thunderstorms can develop due to low-level wind convergence downwind of
17490-408: The fuel rods and finally the containment building in which the primary circuit is built. In Belgium it was decided to add an extra barrier, a so-called double containment. The primary containment of the containment building, is a pre-stressed concrete cylinder with steel liner. It is surrounded by a secondary containment made of 1.2 to 1.3m thick reinforced concrete. The space between both containments
17649-548: The government, and on 26 April 2010 King Albert officially accepted the resignation. The Parliamentary elections in Belgium on 13 June 2010 saw the Flemish nationalist N-VA become the largest party in Flanders, and the Socialist Party PS the largest party in Wallonia. Until December 2011, Belgium was governed by Leterme's caretaker government awaiting the end of the deadlocked negotiations for formation of
17808-400: The ground. This is termed virga and is more often seen in hot and dry climates. Stratiform (a broad shield of precipitation with a relatively similar intensity) and dynamic precipitation (convective precipitation which is showery in nature with large changes in intensity over short distances) occur as a consequence of slow ascent of air in synoptic systems (on the order of cm/s), such as in
17967-552: The higher mountains. Windward sides face the east to northeast trade winds and receive much more rainfall; leeward sides are drier and sunnier, with less rain and less cloud cover. In South America, the Andes mountain range blocks Pacific moisture that arrives in that continent, resulting in a desert-like climate just downwind across western Argentina. The Sierra Nevada range creates the same effect in North America forming
18126-568: The incumbent coalition (composed of Flemish and French-speaking Social Democrats, Liberals, and Christian Democrats) maintains a solid majority in Parliament and in all electoral constituencies. On 22 July 2014, King Philippe nominated Charles Michel (MR) and Kris Peeters (CD&V) to lead the formation of a new federal cabinet composed of the Flemish parties N-VA, CD&V, Open Vld and the French-speaking MR, which resulted in
18285-534: The inhabitants of the northernmost part of Gaul . They lived in a region stretching from Paris to the Rhine , which is much bigger than modern Belgium. However, he also specifically used the Latin word " Belgium " to refer to a politically dominant part of that region, which is now in northernmost France. In contrast, modern Belgium, together with neighbouring parts of the Netherlands and Germany, corresponds to
18444-438: The inner cylinder is filled, the amount inside it is discarded, then filled with the remaining rainfall in the outer cylinder until all the fluid in the outer cylinder is gone, adding to the overall total until the outer cylinder is empty. Other types of gauges include the popular wedge gauge (the cheapest rain gauge and most fragile), the tipping bucket rain gauge, and the weighing rain gauge. For those looking to measure rainfall
18603-463: The installation of Leopold I as king on 21 July 1831, now celebrated as Belgium's National Day , Belgium has been a constitutional monarchy and parliamentary democracy , with a laicist constitution based on the Napoleonic code . Although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 (with plural voting until 1919) and for women in 1949. The main political parties of
18762-471: The invasion of Iraq . It is the only country that does not have age restrictions on euthanasia. Verhofstadt's coalition fared badly in the June 2007 elections . For more than a year, the country experienced a political crisis . This crisis was such that many observers speculated on a possible partition of Belgium . From 21 December 2007 until 20 March 2008 the temporary Verhofstadt III Government
18921-422: The island edges. Offshore California , this has been noted in the wake of cold fronts. Rainbands within tropical cyclones are curved in orientation. Tropical cyclone rainbands contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm . The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. The phrase acid rain
19080-620: The lands of the most northerly Belgae – the Morini , Menapii , Nervii , Germani Cisrhenani , and Aduatuci . Caesar found these peoples particularly warlike and economically undeveloped, and described them as kinsmen of the Germanic tribes east of the Rhine. The area around Arlon in southern Belgium was a part of the country of the powerful Treveri , to whom some of them paid tribute. After Caesar's conquests, Gallia Belgica first came to be
19239-427: The maximum raindrop diameter together with fossil raindrop imprints has been used to constrain the density of the air 2.7 billion years ago. The sound of raindrops hitting water is caused by bubbles of air oscillating underwater . The METAR code for rain is RA, while the coding for rain showers is SHRA. In certain conditions, precipitation may fall from a cloud but then evaporate or sublime before reaching
19398-428: The most inexpensively, a can that is cylindrical with straight sides will act as a rain gauge if left out in the open, but its accuracy will depend on what ruler is used to measure the rain with. Any of the above rain gauges can be made at home, with enough know-how. When a precipitation measurement is made, various networks exist across the United States and elsewhere where rainfall measurements can be submitted through
19557-462: The number of heavy precipitation events over many areas during the past century, as well as an increase since the 1970s in the prevalence of droughts—especially in the tropics and subtropics. Changes in precipitation and evaporation over the oceans are suggested by the decreased salinity of mid- and high-latitude waters (implying more precipitation), along with increased salinity in lower latitudes (implying less precipitation and/or more evaporation). Over
19716-404: The oldest unit and a 10% stake in the two newest units. It employs 1074 workers and covers an area of 75 hectares (190 acres). The plant represents about 15% of Belgium's total electricity production capacity. Nuclear energy typically provides between 40%-50% of Belgium's domestically-generated electricity. In order to extend the lifetime of Tihange 3, the operator will receive subsidies through
19875-527: The original design base for Tihange 1. During the first periodic safety review of the unit after 10 years of operation the design base was increased to 0.17g, this corresponded to the design base of the new Tihange 2 and Tihange 3 units. After the Fukushima Daiichi nuclear disaster probabilistic safety studies performed by the Royal Observatory of Belgium predicted earthquakes with peak ground acceleration of up to 0.21g every 10,000 years. The design
20034-657: The other Frankish kingdoms. During the 8th century, the empire of the Franks came to be ruled by the Carolingian dynasty , whose centre of power included the area which is now eastern Belgium. Over the centuries, it was divided up in many ways, but the Treaty of Verdun in 843 divided the Carolingian Empire into three kingdoms whose borders had a lasting impact on medieval political boundaries. Most of modern Belgium
20193-852: The parliament accepted a Dutch version of the Constitution . The Berlin Conference of 1885 ceded control of the Congo Free State to King Leopold II as his private possession. From around 1900 there was growing international concern for the extreme and savage treatment of the Congolese population under Leopold II , for whom the Congo was primarily a source of revenue from ivory and rubber production. Many Congolese were killed by Leopold's agents for failing to meet production quotas for ivory and rubber. In 1908, this outcry led
20352-504: The political and linguistic interests of these communities. The major parties in each community, though close to the political center, belong to three main groups: Christian Democrats , Liberals , and Social Democrats . Further notable parties came into being well after the middle of last century, mainly to represent linguistic , nationalist, or environmental interests, and recently smaller ones of some specific liberal nature. A string of Christian Democrat coalition governments from 1958
20511-478: The precipitation regimes of places they impact, as they may bring much-needed precipitation to otherwise dry regions. Areas in their path can receive a year's worth of rainfall from a tropical cyclone passage. The fine particulate matter produced by car exhaust and other human sources of pollution forms cloud condensation nuclei leads to the production of clouds and increases the likelihood of rain. As commuters and commercial traffic cause pollution to build up over
20670-431: The pressurizer inadvertently opened leading to a quick decrease in pressure in the primary circuit. The safety injection system activated as designed and injected cold water ending the transient. On 5 July 2005 a relay of one of the six diesel generators of Tihange 2 was replaced. The device was not correctly tuned which meant that it would not be available during an accident, resulting in less redundancy. Greens member of
20829-463: The primary heatsink. The primary heatsink is the Meuse river while the secondary heatsink is water from underground water tables. Nuclear plants are designed with multiple physical barriers to keep fission productions from escaping into the environment. In the case of a pressurized water reactor there are three barriers: the fuel cladding which surround the fuel pellets, the primary circuit which houses
20988-579: The primary types are A, tropical; B, dry; C, mild mid-latitude; D, cold mid-latitude; and E, polar. The five primary classifications can be further divided into secondary classifications such as rain forest , monsoon , tropical savanna , humid subtropical , humid continental , oceanic climate , Mediterranean climate , steppe , subarctic climate , tundra , polar ice cap , and desert . Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 and 2,000 mm (69 and 79 in). A tropical savanna
21147-399: The rainfall time-structure n-index . The average time between occurrences of an event with a specified intensity and duration is called the return period . The intensity of a storm can be predicted for any return period and storm duration, from charts based on historic data for the location. The return period is often expressed as an n -year event. For instance, a 10-year storm describes
21306-425: The reactor vessel. At the end of March 2014 the test results revealed a different outcome compared to what was anticipated by experts. Therefore, the operator (GDF Suez) decided to stop the affected power plant until a clarification could be found and further operation of the powerplant is declared safe. After a re-qualification of the ultrasonic equipment and additional tests on a more similar German made piece of steel
21465-477: The reactor was restarted in November 2015. A separate investigation by Oak Ridge National Laboratory also justified the restart of the unit. The unexpected results were said to be an anomaly with the original test piece. Tihange 1 was shut down from 7 September 2016 to 20 May 2017 for works on the non nuclear infrastructure. During construction works for safety upgrades a non nuclear building with auxiliary pumps
21624-554: The reactors. The restart of reactor Doel-1 and Doel-2 was already postponed earlier from October to December 2018 because of needed maintenance. After inspection in Doel-4 and Tihange-2, concrete decay was found in the ceilings of the buildings as well. On 24 September 2018, Minister Marie-Christine Marghem of Energy, mentioned during a press-conference that she would contact the Netherlands, France and Germany to help Belgium with extra capacity for electricity. Only one nuclear power station
21783-447: The reservoir is sufficient for almost 24 hours. After those 24 hours mobile pumps are used to fill up the reservoir. Each unit has its own cooling tower: the cooling tower of Unit 1 has a height of 159.8 metres, that of Unit 2 measures 159.02 metres and that of Unit 3 159.27 metres. Every unit has also its own chimney, which are in opposite to that of other nuclear power stations realized as rooftop guyed steel chimneys: The total height of
21942-428: The return period (assuming the probability remains the same for each year). For instance, a 10-year storm has a probability of occurring of 10 percent in any given year, and a 100-year storm occurs with a 1 percent probability in a year. As with all probability events, it is possible, though improbable, to have multiple 100-year storms in a single year. The Quantitative Precipitation Forecast (abbreviated QPF)
22101-534: The richest region in terms of GDP per capita . Belgium is also home to two main linguistic communities: the Flemish Community ( Dutch -speaking), which constitutes about 60 percent of the population, and the French Community ( French -speaking), which constitutes about 40 percent of the population. A small German-speaking Community , making up around one percent of the population, exists in
22260-442: The rising air motion of a large-scale flow of moist air across the mountain ridge, resulting in adiabatic cooling and condensation. In mountainous parts of the world subjected to relatively consistent winds (for example, the trade winds ), a more moist climate usually prevails on the windward side of a mountain than on the leeward or downwind side. Moisture is removed by orographic lift, leaving drier air (see katabatic wind ) on
22419-533: The southeast to the Hercynian orogenic belt . The Paris Basin reaches a small fourth area at Belgium's southernmost tip, Belgian Lorraine . The coastal plain consists mainly of sand dunes and polders . Further inland lies a smooth, slowly rising landscape irrigated by numerous waterways, with fertile valleys and the northeastern sandy plain of the Campine ( Kempen ). The thickly forested hills and plateaus of
22578-412: The stress-test action plan (BEST). All units will have functional containment filter venting systems by 2017. Every unit has at least one steam driven feedwater pump which can supply the steam generators with water to cool down the reactor. These turbine driven pumps can cool down the plant even when no electrical power is available to power the motor driven feedwater pumps during a station blackout like
22737-448: The transition from a unitary to a federal arrangement between 1970 and 1993. Despite the reforms, tensions have persisted: there is particularly significant separatist sentiment among the Flemish ; language laws such as the municipalities with language facilities have been the source of much controversy; and the government formation period following the 2010 federal election set a world record at 589 days. Unemployment in Wallonia
22896-492: The tropics since the 1970s. Globally there has been no statistically significant overall trend in precipitation over the past century, although trends have varied widely by region and over time. Eastern portions of North and South America, northern Europe, and northern and central Asia have become wetter. The Sahel, the Mediterranean, southern Africa and parts of southern Asia have become drier. There has been an increase in
23055-543: The vicinity of cold fronts and near and poleward of surface warm fronts . Similar ascent is seen around tropical cyclones outside the eyewall , and in comma-head precipitation patterns around mid-latitude cyclones . A wide variety of weather can be found along an occluded front, with thunderstorms possible, but usually, their passage is associated with a drying of the air mass. Occluded fronts usually form around mature low-pressure areas. What separates rainfall from other precipitation types, such as ice pellets and snow,
23214-728: The war were known as the Rape of Belgium due to German excesses. Belgium assumed control of the German colonies of Ruanda-Urundi (modern-day Rwanda and Burundi ) during the war, and in 1924 the League of Nations mandated them to Belgium. In the aftermath of the First World War, Belgium annexed the Prussian districts of Eupen and Malmedy in 1925, thereby causing the presence of a German-speaking minority. German forces again invaded
23373-702: The war. The Belgian Congo gained independence in 1960 during the Congo Crisis ; Ruanda-Urundi followed with its independence two years later. Belgium joined NATO as a founding member and formed the Benelux group of nations with the Netherlands and Luxembourg. Belgium became one of the six founding members of the European Coal and Steel Community in 1951 and of the European Atomic Energy Community and European Economic Community , established in 1957. The latter has now become
23532-408: The warm conveyor belt), forcing a surface trough to continue into the cold sector on a similar curve to the occluded front. The front creates the portion of an occluded cyclone known as its comma head , due to the comma -like shape of the mid-tropospheric cloudiness that accompanies the feature. It can also be the focus of locally heavy precipitation, with thunderstorms possible if the atmosphere along
23691-555: The water droplets in a cloud to remain stationary. When air turbulence occurs, water droplets collide, producing larger droplets. As these larger water droplets descend, coalescence continues, so that drops become heavy enough to overcome air resistance and fall as rain. Coalescence generally happens most often in clouds above freezing (in their top) and is also known as the warm rain process. In clouds below freezing, when ice crystals gain enough mass they begin to fall. This generally requires more mass than coalescence when occurring between
23850-515: Was available until November, because the repairs of the concrete ceilings take too much time. Engie Electrabel was criticized because the firm had waited too long to communicate the problems with the concrete in the buildings. Belgium – in Europe (light green & dark grey) – in the European Union (light green) Belgium , officially the Kingdom of Belgium ,
24009-568: Was broken in 1999 after the first dioxin crisis , a major food contamination scandal. A "rainbow coalition" emerged from six parties: the Flemish and the French-speaking Liberals, Social Democrats and Greens. Later, a " purple coalition " of Liberals and Social Democrats formed after the Greens lost most of their seats in the 2003 election . The government led by Prime Minister Guy Verhofstadt from 1999 to 2007 achieved
24168-549: Was built by FRAMACEC ( Framatome - ACEC - Cockerill ) and Tihange 3 by the ACECOWEN ( ACEC - Cockerill - Westinghouse ) consortium . Tihange 2 was shut down at the beginning of June 2012 for a planned inspection. The ultrasonic inspection revealed that there were thousands of semi laminar flaws in the reactor vessel's steel rings forged by Rotterdam Drydocks . These were determined to be hydrogen flakes , which influence steel brittleness and vessel pressure . The reactor remained offline for further inspections and assessment for
24327-471: Was damaged. The reactor had to remain shut down while the building was fixed and the ground layers under the building were reinforced. The plant consists of three second-generation pressurized water reactors with a total net capacity of 3,008 MW e , slightly more than Belgium's other nuclear power plant at Doel . Its three units are rated as follows: The design of the plants is reviewed completely every ten years. This so-called RD (révision décennale)
24486-426: Was designated the first permanent President of the European Council on 19 November 2009, he offered the resignation of his government to King Albert II on 25 November 2009. A few hours later, the new government under Prime Minister Yves Leterme was sworn in. On 22 April 2010, Leterme again offered the resignation of his cabinet to the king after one of the coalition partners, the OpenVLD , withdrew from
24645-494: Was first used by Scottish chemist Robert Augus Smith in 1852. The pH of rain varies, especially due to its origin. On America's East Coast, rain that is derived from the Atlantic Ocean typically has a pH of 5.0–5.6; rain that comes across the continental from the west has a pH of 3.8–4.8; and local thunderstorms can have a pH as low as 2.0. Rain becomes acidic primarily due to the presence of two strong acids, sulfuric acid (H 2 SO 4 ) and nitric acid (HNO 3 ). Sulfuric acid
24804-405: Was in office. This was a coalition of the Flemish and Francophone Christian Democrats , the Flemish and Francophone Liberals together with the Francophone Social Democrats . On that day a new government , led by Flemish Christian Democrat Yves Leterme , the actual winner of the federal elections of June 2007 , was sworn in by the king. On 15 July 2008 Leterme offered the resignation of
24963-426: Was in the Middle Kingdom , later known as Lotharingia , but the coastal county of Flanders , west of the Scheldt , became the northernmost part of West Francia , the predecessor of France . In 870 in the Treaty of Meerssen , modern Belgium lands all became part of the western kingdom for a period, but in 880 in the Treaty of Ribemont , Lotharingia came under the lasting control of the eastern kingdom, which became
25122-432: Was originally designed for 1000-yearly floods. After Fukushima the design base of the plants was increased 10,000 yearly floods by building a flood wall around the plant. Earthquakes were also considered. The historically most significant earthquake for Tihange was the one at Tienen in 1828 with a magnitude of 5.4 on the Richter scale . This earthquake resulted in horizontal ground accelerations of up to 0.1g and formed
25281-539: Was subsequently analysed and upgraded for earthquakes up to 0.3g. Besides regular primary level safety systems, in common with most nuclear power plants in the world, Tihange has secondary level safety systems that can autonomously keep the power plant safe during large external accidents such as the crash of an aircraft, external explosions or loss of the primary level. The primary level systems have two or three redundant trains of safety. The secondary level systems are 3x50% or 2x100%. and have their own heatsink separate from
