One of the main problems in the use of nuclear energy is the management of nuclear waste as it is very dangerous and difficult to eliminate. What is done with nuclear waste?
Nuclear waste is one of the main problems related to nuclear energy. If these wastes are not treated properly, they are highly hazardous to the population and the environment.
Radioactive waste can be classified according to its physical and chemical characteristics and by its activity.
Classifying them by their activity we have:
- High-level nuclear waste, composed of elements of…
Nuclear waste management is understood as the set of activities that lead to its reuse, its disappearance or its neutralization and evacuation to suitable places. These measures must guarantee long-term security.
Nuclear waste management encompasses all the administrative and technical tasks necessary for the handling, treatment, conditioning, transport and storage of nuclear waste. These actions must take into account both economic and security factors. Isolation of nuclear waste
The isolation of nuclear waste is done through the interposition of natural and…
The storage of nuclear waste of low and medium activity is based on the interposition of natural and artificial barriers between said nuclear waste and the environment, so that they are perfectly isolated for the time necessary until their radioactivity decays to harmless levels.
The storage of radioactive waste of low and medium activity is carried out in facilities prepared for it. Most of the waste is cleaning rags, filters and impurities of circuits, ion exchange resins, pieces of facilities, etc., coming from nuclear power plants. Also stored are gloves, syringes,…
The Vandellós I nuclear power plant is a graphite-gas nuclear power plant that began operating in 1972. It was part of the group of first generation nuclear power plants in Spain, formed by the Zorita nuclear power plant, Santa Mª de Garoña and the Vandellós I nuclear power plant. It was owned by the Spanish-French company HIFRENSA (Hispano-Francesa de Electricidad).
The nuclear power plant had 480 megawatts (MW) of power. So far the Spanish nuclear power plants were refrigerated and moderated by water. The Vandellós plant, on the other hand, was cooled by gas and its nuclear reaction…
The transport of radioactive substances generated by the different applications of nuclear energy is carried out according to the recommendations established by the International Atomic Energy Agency (IAEA), included in the legislation in force through the European Agreement on the Transport of Dangerous Goods by Road.
The set of measures established has the objective of minimizing the probability of a nuclear accident occurring. In case of a nuclear accident the objective is to mitigate its effects, avoiding the dispersion of radioactive material and its possible assimilation by…
Mexico is rich in hydrocarbon resources and is a net exporter of energy. The country's interest in nuclear energy is based on the need to reduce its dependence on these non-renewable energy sources. In recent years, energy in Mexico is increasingly dependent on natural gas.
Energy growth in Mexico was very rapid in the 1990s, but then stabilized for a few years. Since 2007, a new growth in the demand for electric power was expected, up to an average rate of almost 6% per year.
In 2016, Mexico generated 20% of its electric power through clean sources, including…
Renewable energies are those energies that use an energy or fuel source that is considered inexhaustible or that can be regenerated at the same rate at which it is consumed.
Nuclear energy is not considered a renewable energy source since the fuel used, uranium is not limited. The consumption of nuclear fuel is higher than the generation of natural uranium.
The classification of renewable energies depends on the natural resources that are used. Among them we highlight:
- Solar photovoltaic and thermal energy.
- Wind power.
- Hydraulic energy.…
At the moment of analyzing the disadvantages of nuclear energy in the first place, it is necessary to consider the different areas in which nuclear energy is used. The main use of nuclear energy is the generation of electricity. Although electricity production is the most controversial nuclear application, nuclear technology is also used in the military, medical or environmental fields, among others.
One of the advantages of nuclear energy is that it reduces the dependence on thermal power plants and, therefore, the consumption of fossil fuels. However,…
The Chernoby nuclear accident was the worst accident in the history of nuclear energy. After 30 years, Chernobyl's current situation remains delicate.
The recovery of the nuclear accident zone and the cleaning products has resulted in a large amount of radioactive waste and contaminated equipment. The generated nuclear waste is stored in about 800 different sites inside and outside the 30 km exclusion zone around the Chernobyl nuclear reactor.
These nuclear waste are partially stored in containers or buried in trenches, which can lead to the risk of contamination of…
Plutonium is a chemical element, usually of artificial origin, that is used as a nuclear fuel in the manufacture of nuclear weapons.
The symbol of this chemical element is Pu and its atomic number is 94. It is an element that belongs to the series of actinide elements. Plutonium has 16 isotopes, all of them radioactive. The element is a silver metal and has 5 different crystalline structures.
Chemically plutonium is a very active material. It can form compounds with all non-metallic elements, except noble gases. The metal dissolves in acids and reacts with…
Electricity consumption in Argentina has grown strongly since 1990. Per capita consumption was just over 2000 kWh / year in 2002 and increased to around 3000 kWh / year in 2015. Gross electricity production in 2016 was 147 TWh , with 75 TWh (51%) of natural gas, 38 TWh (26%) of hydropower, 21 TWh (14%) of oil, 3 TWh (2%) of coal, 8 TWh (5% *) of nuclear energy and 10 TWh of net import. The total electric power produced by fossil fuels is 99TWh.
In Argentina, approximately 10% of electricity comes from 3 operational nuclear reactors: the Embalse nuclear power plant, a CANDU reactor,…
