Watt is the international standard power unit in SI.
James Watt (1736-1819), the inventor of the steam engine, accepted it as the unit of power in the SI unit system. It is the unit that measures the energy conversion rate (joules) divided by seconds. The watt symbol is represented by the letter W.
1W = 1 J / s
In mechanics the watt is the power developed by a force of a newton applied to a point that moves one meter for a second. That is, if the point on which a force of a newton is applied is displaced at a speed of 1 m / s, the power is equal to 1 watt:
1W = 1N…

The nuclear moratorium is the temporary suspension of the construction and start-up of nuclear power plants.
In 1983 in Spain a National Energy Plan was drafted in which a nuclear moratorium would be decreed in the country. The nuclear moratorium involved the blocking of 5 nuclear power plant projects out of the 7 that had been approved. Technically it was a brake on the dynamics of the development of nuclear energy in the country. What reasons caused the nuclear motive?
There are several reasons that motivated the creation of the nuclear moratorium:
We define electricity as the form of energy that results from the existence of a potential difference between two points. When these two points are put in contact by means of an electrical conductor we obtain an electric current.
In physics, the electric potential energy, also called electrostatic potential energy, is the potential energy of the electrostatic field. This is an energy that has an electrical charge distribution, and is linked to the force exerted by the field generated by the distribution itself. Together with magnetic energy, the electric potential energy constitutes…

Atomic energy comes from the atom, it is the energy that holds together neutrons and protons of the nuclei of atoms. It is also known how nuclear energy, which comes from the nucleus. The name nuclear energy is used because most of the energy of an atom resides in its nucleus.
Two parts of the atom, the nucleus and the crust are differentiated. In the cortex, an indeterminate number of electrons orbit around the nucleus. The nucleus is composed of an indeterminate number of neutrons and protons. The amount of protons in the nucleus will determine the element that the atom is treated,…

What is nuclear energy? 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…

The most important feature of the boiling water reactor (BWR) is the use of pressurized water as a neutron moderator and as a core coolant. Unlike the pressurized water reactor (PWR), it does not…
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.

Ability of a physical system to produce a job.
This definition, although it is the most widespread, can be misleading because of the vagueness of the term "capacity", and therefore, it is better to define the energy as what, when a work occurs, decreases in an amount equal to the work produced. Energy, then, is measured in the same units as labor. History of the study of energy
The notion of energy appears for the first time from the investigations of Joule and Carnot on the conversion of heat in mechanical work and thanks to the theory of Helmholtz in which it connects…

A neutron is a subatomic particle that is part of the atom (along with the proton and the electron). Neutrons and protons form the atomic nucleus. Neutrons have no net electric charge, unlike the proton that has a positive electric charge.
The difference in the number of neutrons in the nucleus of an atom does not imply the variation of the nature of the atom itself, but it does determine the isotope to which it is a part.
In nuclear energy the concept "uranium enrichment" refers to the alteration of the number of neutrons in the atomic nucleus in order to obtain another…
The main use of nuclear energy is the production of electrical energy. Nuclear power plants are responsible for generating electricity. Nuclear fission reactions are generated in the nuclear reactors of the nuclear power plants. With these reactions, thermal energy is obtained that will be transformed into mechanical energy and later into electrical energy.
However, there are many other uses in which nuclear energy is used directly or indirectly.
Working with different isotopes of the same element, you can use nuclear technology for other uses in various fields:…

We define radioactivity as the spontaneous emission of particles (alpha particles, beta particles, neutrons) or radiations (range, K capture), or both at the same time, coming from the disintegration of certain nuclides that form them, due to an arrangement in its internal structure.
Radioactive decay occurs in unstable atomic nuclei, that is, those that do not have enough binding energy to keep the nucleus together due to an excess of protons or neutrons.
Radioactivity can be natural or artificial. In natural radioactivity, the substance already has it in the natural state. In…
Mechanical energy can be defined as the ability to produce a mechanical work that a body possesses due to causes of mechanical origin, such as its position or its speed. There are two forms of mechanical energy that are kinetic energy and potential energy.
The mechanical energy of a body is the sum of its kinetic energy and its potential energy. Mechanical energy can be partially transformed into other types of energy, such as electrical energy (in a ventilator), and can be obtained by transforming other energies, such as chemical energy (in a person who walks).
The kinetic energy…

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 power plant Angra is one of the few nuclear plants in Brazil. The plant is located in Angra Nuclear Power Plant (CNAAA) in Playa Itaorna in Angra dos Reis, Rio de Janeiro, Brazil.
This is two nuclear pressurized water reactors
- The nuclear reactor Angra 1 has a net power of 637 MWe, connected to the electricity grid for the first time in 1985.
- The nuclear reactor Angra 2 has a net capacity of 1,350 MWe, I connectado to the electricity grid in 2000.
- It is working on a third reactor, Angra 3, which will have an estimated capacity of 1,405 MWe.…
The Fukushima Daiichi Nuclear Power Plant Fukushima nuclear plant or one (Dai-ichi means "number one" in Japanese) is composed of six nuclear reactor nuclear boiling water (BWR). The plant is located in the city of ÅŒkuma (Fukushima Prefecture, Japan). Uses sea water for cooling.
Located just twelve kilometers from another great power, the Fukushima Daini nuclear plant, Fukushima or II, with four reactors.
In August 1976 permission was granted for the installation of a nuclear power plant in the municipality of Regodola (Lugo). The grant was made to the group of companies comprising Fenosa, Hydroelectric and Electra de Viesgo Biscay, the latter two with a 20% stake.
The Regodola nuclear power plant had had a rated capacity of 1,000 MWe light water. The development of the project and the limits and conditions on nuclear safety in resolving especificavan DG Energy.
At that time in Spain there were three operating nuclear power plants, three in construccióny 15 project.…
The Santa María de Garoña Nuclear Power Plant is a nuclear power power generation located in Santa Maria de Garona, province of Castilla y Leon in Spain. His life ended in 2012. Initially the expected useful life of the plant was until 2011 and was last operating license until 2009. After analyzing a report by the Nuclear Safety Council (CSN), the Spanish government decided to extend the authorization until 2013. the report set out a series of limits and conditions that must be met after the Fukushima nuclear accident.
