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. 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…
Renewable energies are those energies using an energy source or fuel which is considered inexhaustible or can be regenerated at the same rate at which it is consumed.
The classification of renewable energy depends on natural resources exploited. Solar energy
We distinguish two ways of using solar energy:
- Solar thermal energy.
- Solar photovoltaic energy.
The use of solar thermal is to use heat energy obtained from solar radiation to heat a fluid, depending…
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…
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).…
