Non-renewable energies are energies generated from non-renewable resources; a group of resources that cannot be restored once used. These resources mainly include fossil fuels (coal, oil, natural gas), nuclear fuels and biofuels.
Unlike non-renewable resources, we have renewable energies that include: solar energy, wind energy, hydraulic energy as the most prominent. Fossil energy and fossil fuels
Resources such as coal, oil and natural gas take several thousand years to form and cannot be replaced as quickly as they are used today. It is believed that fossil-based resources will be too expensive to process, that humans will have to resort to other sources…

What is nuclear energy? A common nuclear energy definition that is frequently given: nuclear energy is the internal energy in the atomic nucleus, that is the central part of an atom. Atoms are the smallest particles in which a material can be divided. The nucleus of an atom is composed of two subparticles: neutrons and protons. These subparticles are held together due to energy links. At the moment in which these bonds are modified, a large amount of thermal energy is released in the form of heat.
Nuclear technology deals with the use of this internal energy for a wide variety of applications. The most well-known use of nuclear energy is the generation of electric…

In nuclear energy, we refer to nuclear accident to those incidents that emit a certain level of radiation, which could harm public health. To determine the severity of an accident, an International Nuclear Event Scale (better known by its acronym INES) has been established.
Nuclear accidents are classified as nuclear accidents and incidents depending on the severity´s level. In this classification nuclear accidents and radioactive accidents are included. To understand the difference between these two types of accidents, a nuclear accident could be the failure of a reactor of a nuclear power plant and a radiation accident could be when pouring a radiation source to a…

The Doel nuclear power plant (in Dutch: Kerncentrale Doel) is in the territory of Doel (the municipality of Beveren), on the left bank of the Scheldt in Belgium. It is located 25 km north of Antwerp, 42 km north-west of Brussels and 136 km south-southeast of Amsterdam (line all distances).
The nuclear power plant is operated by Electrabel operator. Has a layout of four pressurized water reactors (PWR) Westinghouse (Doel 1, 2 and 3) and Framatome / AREVA (Doel 4)
One of the uses of nuclear energy is developed in the military and arms industry. One of these military uses is the development of the atomic bomb with a much greater devastation capacity than with any other type of bomb.
The atomic bomb is a weapon of mass destruction, so the international community limits and sanctions the production of such weapons with the Nuclear Non-Proliferation Treaty. The explosive energy of the atomic bombs is measured by comparison with that emitted by a mass of one million tons of TNT (megaton). Atomic bomb operation
The operation of the atomic bomb is based on a process of dividing the atomic nucleus of a heavy element, called…

In physics, electromagnetic radiation (or gamma γ radiation) is the radiation of energy in the electromagnetic field. It is a phenomenon both wave and corpuscular:
The wave phenomenon is given by a wave in the electric field and in the magnetic field and is described mathematically as a solution of the wave equation, obtained in turn from Maxwell's equations according to the theory of classical electrodynamics.
corpuscular nature, or quantified, can instead be described as a stream of photons that, in a vacuum, travel at the speed of light. This fact was made known by the modern studies of physics at the beginning of the 20th century, which recognized in the…

In physics and chemistry, an ion is an atom or molecule that does not have a neutral electrical charge. An ion with a positive electric charge is called cation, and an ion with a negative electric charge is anion.
The process of gaining or losing electrons (with respect to the neutral atom or molecule) is called ionization. Cations and anions are usually represented with the corresponding atom symbol and the "+" or "-" symbol, respectively. If the number of electrons won or lost is greater than one, this is also indicated.
The cations and anions are attracted to the cathode and anode, respectively.
Michael Faraday was the first to propose the existence…

Nuclear power in India is currently in a state of growth with important nuclear energy development plans. India has set two goals for the years 2020 and 2050.
India is one of the few countries within a limited group, which has capacity from beginning to end: to extract uranium, enrich it, use it in nuclear power plants and then reprocess waste so that each watt of energy is harnessed from scarce uranium resource. Since the country believes that plutonium, the so-called “long-lived dirty product” of nuclear programs, is also a rich source of energy, extremely modern nuclear reactors are being designed to make the most of energy.
The only 500 MW Player Reactor…

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 water, although moderately compared to acids.
Although traces can be found in nature, all plutonium…

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.
- Seawater energy.
- Biomass energy
- Geothermal energy.

Industry is one of the fields in which nuclear energy is used. The use of nuclear energy in modern industry in developed countries is very important for the improvement of industrial processes, for measurements and automation, and for quality control.
The use of nuclear radiation is applied in a wide range of activities. These activities can be quality control of raw materials of industrial processes (cement, thermal power plants, oil refineries, etc.), or quality control of products manufactured in series. In the case of series production, it is used as a prerequisite for the complete automation of high-speed production lines.
In the field of industry, irradiation…
