Nuclear Power in Brazil

Nuclear Power in Brazil

In 2016, gross electricity production in Brazil was 579 TWh, including 381 TWh (66%) of hydroelectric power, 56 TWh (10%) of gas, 51 TWh (9%) of biomass and waste, 34 TWh ( 6%) of wind energy and solar energy, 26 TWh (4%) of coal, 16 TWh (3%) of nuclear and 15 TWh (3%) of oil.

The high dependence on hydroelectric energy leads to a certain climate vulnerability that is driving the policy to reduce dependence on it.

Around 40% of Brazil's electricity is produced by the national system of Eletrobrás a. About 20% of electricity comes from public utilities, and the rest comes…

Nuclear Moratorium

The nuclear moratorium supposed blocking 5 projects of nuclear power plants that had approved the 7 (and some insiders) in Spain.

The National Energy Plans and Nuclear Moratorium

In 1983 he drafted a National Energy Plan in qual nuclear energy in Spain was hit hard.

To bring national electricity production to energy demand and adjust prices of the Congreos Diputoado in June 1984 approved the 1983 National Energy Plan (PEN-83).

The nuclear stop was the main novelty of the PEN-83 that was slowing building program of nuclear power.

Nuclear Energy Situation in the World

Nuclear Energy Situation in the World

Nuclear energy began to develop during the first decade of 1940. Initially, the research was aimed at the development and production of the atomic bomb. Subsequently, research began on other applications of nuclear energy; the investigation focused on the peaceful use of nuclear energy.

Currently, there are 30 countries in the world that have nuclear power plants for the generation of electricity. In any case, the number of countries that take advantage of nuclear energy is much greater since countries such as Denmark and Italy, which do not have any nuclear facilities, obtain about…

History of Nuclear Energy

History of Nuclear Energy

To explain the history of nuclear energy we could distinguish three major stages:

  • Physical and chemical scientific studies of the elements.
  • The development of the nuclear bomb during World War II.
  • Use of nuclear energy in the civil field.

Scientific studies cover this whole period since the first Greek philosophers began to define atoms, until the development of the first nuclear bomb. In this process, different scientists discover the presence of electrons, neutrons and protons and properties that make one atom more radioactive than another.

Nuclear Fusion

Nuclear Fusion

Nuclear fusion is a nuclear reaction through which two light nuclei of atoms, usually hydrogen and its isotopes (deuterium and tritium), are combined forming a heavier nucleus. This binding is usually accompanied by the emission of particles (in case of deuterium nuclei one neutron is emitted). This nuclear fusion reaction releases or absorbs a lot of energy in the form of gamma rays and kinetic energy of the emitted particles.This large amount of energy transforms matter to a plasma state.

The nuclear fusion reactions can emit or absorb…

Nuclear fusion reactor - ITER Project

Nuclear fusion reactor - ITER Project

The experimental fusion reactor ITER (International Thermonuclear Experimental Reactor) is a large-scale scientific experiment designed to test the feasibility of fusion as an energy source. Currently the ITER fusion reactor is under construction in the south of France, in Cadarache.

At the industry level, nuclear fusion does not exist yet. Since the 50s under investigation on the use of the energy generated in the nuclear fusion of light atoms into heavier. The development of nuclear fusion is considered very important because of the advantage offered by the large amount of energy released…

Nuclear Power in Mexico

Nuclear Power in Mexico

Mexico is rich in hydrocarbon resources and is a net exporter of energy. Country's interest in nuclear energy is based on the need to reduce their dependence on these sources of energy. In recent years, Mexico's energy is increasingly dependent on natural gas.

The energy growth was very rapid in the 1990s, but then stabilized for a few years. Since 2007 expected new growth in demand for electricity to an average rate of almost 6% per year. In 2007, we generated 257 million kWh. Supply Origin is varied electric, gas 126 TWh (49%), oil of 52 TWh (20%), coal 32 TWh (12.5%) and hydroelectric…

Nuclear Power in Argentina

Electricity consumption in Argentina has grown strongly since 1990. Per capita consumption was just over 2,000 kWh / year in 2002 and increased to over 2,600 kWh / year in 2007. Gross production of electricity in 2007 was 115 million kWh, 54% from gas, 27% hydro, 9.4% oil, a 2.2% from coal, and 6.3% (7.2 million kWh) of nuclear origin. In 2008, nuclear energy provides more than 6.8 million kWh of electricity - about 6.2% of total electricity generation.

In Argentina, the electricity production is largely privatized, and is regulated by the ENRE (National Regulatory Authority for Electricity).…

Current Situation in Chernobyl After Nuclear Accident

Current Situation in Chernobyl After Nuclear Accident

The recovery of the accident area and cleaning products has resulted in a large amount of radioactive waste and contaminated equipment, stored at about 800 different sites inside and outside the 30 km exclusion zone around the nuclear reactor 4 from Chernobyl.

These nuclear wastes are partially stored in containers or buried in trenches, which may lead to a risk of contamination of groundwater.

The sarcophagus and the proliferation of waste storage sites have been assessed as a source of hazardous radioactivity in nearby areas, and some NEA experts feared that the sinking of the…

 Almaraz-1 nuclear power plant, Spain

Almaraz Nuclear Power supplied 16,000 million kWh annually throughout Spain.

The Alamarz Nuclear Power Plants I and II are located in the municipality of Almaraz de Tajo (Cáceres). The land owned by the central cover an area of 1,683 hectares located in the municipalities of Almaraz, Saucedilla and Serrejón Romangordo.

The Almaraz consists of two light water reactors of 2686 MW pressurized thermal, each with three cooling circuits, and manufacturing and construction is a Spanish contribution greater than 80 100. Both units use as fuel slightly enriched uranium oxide…

Embalse nuclear power plant, Argentina

Embalse nuclear power plant, Argentina

The Embalse nuclear power plant is a central power generation, located near the city of Embalse, province of Cordoba in Argentina.

In addition to power generation has other applications in nuclear medicine because thanks to their recharge nuclear fuel during operation, is also used to generate isotopes for medical applications, such as cobalt 60

From the point of view of the capacity of power generation, nuclear power plant reservoir has a capacity of 648 MWe gross power.

The operator is Nucleoeléctrica Argentina S.A. since 1994.

Cattenom I Nuclear Power Plant

Cattenom I Nuclear Power Plant

The Cattenom Nuclear Power Plant is a nuclear power plant located in France. It is currently operated by Electricité de France (EDF). Geographically it is located in Lorraine, in the town of Cattenom, on the Moselle banks between Thionville and Trier. The cities of Luxembourg, Arlon, and Metz are very close to the nuclear power plant.

Luxembourg, Saarland and Belgium demanded closure of the plant. In spite of this, there is a project under way to extend its useful life until 2025.
