List Of Civilian Nuclear Accidents
This article lists notable civilian accidents involving fissile nuclear material or nuclear reactors. Military accidents are listed at List of military nuclear accidents. Civil radiation accidents not involving fissile material are listed at List of civilian radiation accidents. For a general discussion of both civilian and military accidents, see Nuclear and radiation accidents. Scope of this article In listing civilian nuclear accidents, the following criteria have been followed: # Notably severe: there must be well-attested and substantial health damage, property damage or contamination; if an International Nuclear Event Scale (INES) level is available, of at least two. # Nuclear aspect: the damage must be related directly to nuclear operations or materials; the event should involve fissile material or a reactor, not merely (for example) having occurred at the site of a nuclear power plant. # Primarily civilian: the nuclear operation/material must be principally for non-milit ...

Civilian
A civilian is a person who is not a member of an armed force. It is war crime, illegal under the law of armed conflict to target civilians with military attacks, along with numerous other considerations for civilians during times of war. If a civilian engages in hostilities, they are an unlawful combatant and temporarily lose their protection from attack. It is slightly different from a non-combatant, because some non-combatants are not civilians (for example, people who are not in a military but support war effort or military operations, military chaplains, or military personnel who are serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary international law, customary laws of war and Treaty, international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is an internal one (a civil war) or an internationa ...

Fission Product
Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons, the release of heat energy (kinetic energy of the nuclei), and gamma rays. The two smaller nuclei are the ''fission products''. (See also Fission products (by element)). About 0.2% to 0.4% of fissions are ternary fissions, producing a third light nucleus such as helium-4 (90%) or tritium (7%). The fission products themselves are usually unstable and therefore radioactive. Due to being relatively neutron-rich for their atomic number, many of them quickly undergo beta decay. This releases additional energy in the form of beta particles, antineutrinos, and gamma rays. Thus, fission events normally result in beta and additional gamma radiation that begins immediately after, even though this radiation is not produced directly by the fission even ...

Vinca Nuclear Institute
''Vinca'' (; Latin: ''vincire'' "to bind, fetter") is an Old World genus of flowering plants in the family Apocynaceae, The English name periwinkle is shared with the related genus ''Catharanthus'' (and with the mollusc ''Littorina littorea''). Some ''Vinca'' species are cultivated but have also spread invasively. Additionally, some species have medicinal uses. The most widespread species is Vinca minor. Description ''Vinca'' plants are subshrubs or herbaceous, and have slender trailing stems long but not growing more than above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely. The leaves are opposite, simple broad lanceolate to ovate, long and broad; they are evergreen in four species, but deciduous in the herbaceous ''V.'' ''herbacea'', which dies back to the root system in winter.Blamey, M., & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. Hodder & Stoughton.Huxley, A., ed. (1992). ''New RHS ...

Socialist Federal Republic Of Yugoslavia
The Socialist Federal Republic of Yugoslavia (commonly abbreviated as SFRY or SFR Yugoslavia), known from 1945 to 1963 as the Federal People's Republic of Yugoslavia, commonly referred to as Socialist Yugoslavia or simply Yugoslavia, was a country in Central Europe, Central and Southeast Europe. It was established in 1945, following World War II, and lasted until 1992, breakup of Yugoslavia, dissolving amid the onset of the Yugoslav Wars. Spanning an area of in the Balkans, Yugoslavia was bordered by the Adriatic Sea and Italy to the west, Austria and Hungarian People's Republic, Hungary to the north, People's Republic of Bulgaria, Bulgaria and Socialist Republic of Romania, Romania to the east, and People's Socialist Republic of Albania, Albania and Greece to the south. It was a One-party state, one-party socialist state and federation governed by the League of Communists of Yugoslavia, and had six constituent republics: Socialist Republic of Bosnia and Herzegovina, Bosnia and Her ...

Vinča
Vinča ( sr-cyr, Винча, ) is a List of Belgrade neighborhoods, suburban settlement of Belgrade, Serbia. It is part of the municipality of Grocka. Vinča-Belo Brdo, an important archaeological site that gives its name to the Neolithic Vinča culture, is located in the village. Location Vinča is located on the confluence of the Bolečica river into the Danube, on the Danube's right bank, east of Belgrade and west of its own municipal seat of Grocka. It is situated along the stream of ''Makački potok'', which empties into the Bolečica. Population Vinča is statistically classified as a rural settlement (village). Originally it was situated 3 km from the road of ''Smederevski put'', but as the settlement expanded it now stretches from the Danube to the ''Smederevski put'', making urbanistic connections to the surrounding settlements of Ritopek, Boleč, Leštane and Kaluđerica, though making one continuous built-up area with Belgrade itself. Like the surrounding settlem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Research Universal Reactor
The National Research Universal (NRU) reactor was a 135 MW nuclear research reactor built in the Chalk River Laboratories, Ontario, one of Canada’s national science facilities. It was a multipurpose science facility that served three main roles. It generated radionuclides used to treat or diagnose over 20 million people in 80 countries every year (and, to a lesser extent, other isotopes used for non-medical purposes). It was the neutron source for the National Research Council of Canada, NRC Canadian Neutron Beam Centre: a materials research centre that grew from the Nobel Prize-winning work of Bertram Brockhouse. It was the test bed for Atomic Energy of Canada Limited to develop fuels and materials for the CANDU reactor. At the time of its retirement on March 31, 2018, it was the world's oldest operating nuclear reactor. History The NRU reactor design was started in 1949. It is fundamentally a Canadian design, significantly advanced from NRX. It was built as the successor to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant (U
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a junior commissioned officer rank in the armed forces of many nations, as well as fire services, emergency medical services, security services and police forces. The rank in armies and air forces is often subdivided into subcategories of seniority. In English-speaking navies, lieutenants are often equivalent to the army rank of captain; in other navies, the lieutenants are usually equal to their army counterparts. ''Lieutenant'' may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is "second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieutenant governor in various governments, such as the viceregal representatives of the Crown in Canadian province ...

Dosimetry
Radiation dosimetry in the fields of health physics and radiation protection is the measurement, calculation and assessment of the ionizing radiation dose absorbed by an object, usually the human body. This applies both internally, due to ingested or inhaled radioactive substances, or externally due to irradiation by sources of radiation. Internal dosimetry assessment relies on a variety of monitoring, bio-assay or radiation imaging techniques, whilst external dosimetry is based on measurements with a dosimeter, or inferred from measurements made by other radiological protection instruments. Radiation dosimetry is extensively used for radiation protection; routinely applied to monitor occupational radiation workers, where irradiation is expected, or where radiation is unexpected, such as in the contained aftermath of the Three Mile Island, Chernobyl or Fukushima radiological release incidents. The public dose take-up is measured and calculated from a variety of indicators s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ottawa River
The Ottawa River (, ) is a river in the Canadian provinces of Ontario and Quebec. It is named after the Algonquin word "to trade", as it was the major trade route of Eastern Canada at the time. For most of its length, it defines the border between these two provinces. It is a major tributary of the St. Lawrence River and the longest river in Quebec. Geography The river rises at Lac des Outaouais, north of the Laurentian Mountains of central Quebec, and flows west to Lake Timiskaming. From there its route has been used to define the interprovincial border with Ontario. From Lake Timiskaming, the river flows southeast to Ottawa and Gatineau, where it tumbles over Chaudière Falls and further takes in the Rideau River, Rideau and Gatineau River, Gatineau rivers. The Ottawa River drains into the Lake of Two Mountains and the St. Lawrence River at Montreal. The river is long; it drains an area of , 65 per cent in Quebec and the rest in Ontario, with a mean discharge of . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reactor Coolant
A nuclear reactor coolant is a coolant in a nuclear reactor used to remove heat from the nuclear reactor core and transfer it to electrical generators and the environment. Frequently, a chain of two coolant loops are used because the primary coolant loop takes on short-term radioactivity from the reactor. Water Almost all currently operating nuclear power plants are light water reactors using ordinary water under high pressure as coolant and neutron moderator. About 1/3 are boiling water reactors where the primary coolant undergoes phase transition to steam inside the reactor. About 2/3 are pressurized water reactors at even higher pressure. Current reactors stay under the critical point at around 374 °C and 218 bar where the distinction between liquid and gas disappears, which limits thermal efficiency, but the proposed supercritical water reactor would operate above this point. Heavy water reactors use deuterium oxide which has identical properties to ordinary water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
