Nuclear Power In Uruguay
The use of nuclear energy in Uruguay is prohibited by law 16.832 of 1997. Despite this, the country has several institutions that regulate its use, such as the Center for Nuclear Research (''Centro de Investigaciones Nucleares'') or the National Regulation Authority on Radiological Protection (''Autoridad Reguladora Nacional en Radioprotección''). Furthermore, for several years Uruguay had a small nuclear reactor for research and personnel training. It was brought from the United States in 1964 and began to work in the building of the Center for Nuclear Research in Malvin Norte in 1978. It was turned off because of the detection of corrosion in 1985 and all nuclear fuel was removed. A year later, the Chernobyl and Goiânia nuclear accidents occurred. This influenced public opinion, and in 1988 —during the first presidency of Julio Maria Sanguinetti— a cooperation agreement of nuclear energy between Uruguay and Canada was signed, in which they planned the construction of a nucle ...

Nuclear Power
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear ''fission'' of uranium and plutonium in nuclear power plants. Nuclear ''decay'' processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as ''Voyager 2''. Generating electricity from fusion power, ''fusion'' power remains the focus of international research. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earth Summit (1992)
The United Nations Conference on Environment and Development (UNCED), also known as the Rio Conference or the Earth Summit (Portuguese: ECO92), was a major United Nations conference held in Rio de Janeiro from June 3 to June 14, 1992. Earth Summit was created as a response for member states to cooperate together internationally on development issues after the Cold War. Due to issues relating to sustainability being too big for individual member states to handle, Earth Summit was held as a platform for other member states to collaborate. Since the creation, many others in the field of sustainability show a similar development to the issues discussed in these conferences, including non-governmental organizations (NGOs). Issues addressed The issues addressed includes: * systematic scrutiny of patterns of production—particularly the production of toxic components, such as lead in gasoline, or poisonous waste including radioactive chemicals * alternative sources of energy to re ...

Julio María Sanguinetti
Julio María Sanguinetti Coirolo (; born 6 January 1936 in Montevideo, Uruguay) is a Uruguayan politician, lawyer and journalist, who twice served as President of Uruguay (from March 1985 until March 1990, and again, from March 1995 until March 2000) for the Colorado Party (Uruguay), Partido Colorado.

Chernobyl Disaster
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion roubles—roughly US$68 billion in 2019, adjusted for inflation. The accident occurred during a safety test meant to measure the ability of the steam turbine to power the emergency feedwater pumps of an RBMK-type nuclear reactor in the event of a simultaneous loss of external power and major coolant leak. During a planned decrease of reactor power in preparation for the test, the operators accidentally dropp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Budget
A government budget is a document prepared by the government and/or other political entity presenting its anticipated tax revenues (Inheritance tax, income tax, corporation tax, import taxes) and proposed spending/expenditure (Healthcare, Education, Defence, Roads, State Benefit) for the coming financial year. In most parliamentary systems, the budget is presented to the legislature and often requires approval of the legislature. Through this budget, the government implements economic policy and realizes its program priorities. Once the budget is approved, the use of funds from individual chapters is in the hands of government ministries and other institutions. Revenues of the state budget consist mainly of taxes, customs duties, fees and other revenues. State budget expenditures cover the activities of the state, which are either given by law or the constitution. The budget in itself does not appropriate funds for government programs, hence need for additional legislative measur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uruguayan Peso
Uruguayan peso ( es, peso uruguayo) has been a name of the Uruguayan currency since Uruguay's settlement by Europeans. The present currency, the ''peso uruguayo'' (ISO 4217 code: ) was adopted in 1993 and is subdivided into 100 '' centésimos'', although centésimos are not currently in use. Introduction Uruguay obtained monetary stability in 1896, based on the gold standard. This favorable state of affairs ended after World War I. An unsettled period followed. Economic difficulties after World War II produced inflation, which became serious after 1964 and continued into the 1970s. The peso moneda nacional was replaced on 1 July 1975 by the nuevo peso (new peso; ISO 4217 code ) at a rate of 1 new peso for 1000 old pesos. The nuevo peso was also subdivided into 100 ''centésimos''. After further inflation, the peso uruguayo (ISO 4217 code ) replaced the on March 1, 1993, again at a rate of 1 new for 1000 old. Inflation Uruguayans became accustomed to the constant devaluation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockheed Corporation
The Lockheed Corporation was an American aerospace manufacturer. Lockheed was founded in 1926 and later merged with Martin Marietta to form Lockheed Martin in 1995. Its founder, Allan Lockheed, had earlier founded the similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. History Origins Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed a prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I. Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles.
