Watt

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…

Electric power

Electric power

We define electrical energy 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…

Situation of nuclear energy in the world

Situation of nuclear energy 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…

Nuclear Power Plant

Nuclear Power Plant

A nuclear power plant is a facility for obtaining electrical energy using nuclear energy.

Its operation is similar to that of a thermal power plant or that of a solar thermal plant: from a source of energy thermodynamics is used to obtain heat, with the heat to get steam and with the steam to drive a turbine that will generate electricity.

The difference between the different types of electrical installations is in the energy source: a nuclear power plant uses the heat released in the nuclear fission reactions of certain atoms, in a thermal power station the heat source (thermal…

A steam turbine is a machine that exploits the thermal energy of steam under pressure, converting it into useful mechanical energy through a thermodynamic transformation of expansion. Specifically, the steam turbine converts the internal energy of the vapor into kinetic energy of rotation.

The steam turbine, thanks to the highest thermal efficiency and the best power / weight ratio, has completely replaced the steam engine, which was an alternative engine invented by Thomas Newcomen and then significantly improved by James Watt.

From a thermodynamic point of view, the maximum…

Atomic Energy

Atomic Energy

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,…

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.

Definition of energy

Definition of energy

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…

The Nautilus is the first nuclear submarine in the world. It was built in 1954, in Groton, Connecticut, on the east coast of the US. Thanks to the use of nuclear energy have managed to overcome all records of submarine technology to date. Available higher speed and not so often needed up to the surface. It was the first submarine to reach the North Pole in 1958. In 1980 became a Museum.

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…

Cofrentes nuclear power plant, Spain

The Cofrentes nuclear power plant came into operation on 14 October 1984.

This is a nuclear power generation plant with a reactor BWR-6-Boiling Water Reactor (boiling water reactor 6th generation) type originally boast a total installed capacity of 992 MWe but after certain improvements were achieved expand the power in the current 111.85%, equivalent to 1,110 MWe.

 Angra-1 nuclear power plant, Brazil

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.…

Faiichi 1 Fukushima nuclear plant, Japan

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.

Regodola nuclear power plant, Spain

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.

Garoña nuclear power plant, Spain

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.
