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…

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…
The control rods of nuclear reactors provide speed control nuclear fission reactions delas chain. It is cylindrical tubes made of a neutron absorbing material. This material may be boron carbide or alloys of silver, indium and cadmium.
Dimensions of the control rods are the same as those of the rods of nuclear fuel. They are used to provide a rapid means of control of the nuclear reaction. The control rods to regulate the rate of nuclear reaction
A gas reactor or GCR (English gas cooled reactor) is a type of nuclear nuclear reactor of nuclear fission. The neutron moderator of this type of nuclear reactor is graphite. The coolant of the nuclear gas reactor is carbon dioxide in the gaseous state. According to the classification made by the International Atomic Energy Agency of the United Nations, IAEA, this type of reactors includes those of the AGR type (of the English Advanced Gas-cooled Reactor) and Magnox (of the English Magnesium Non-OXidising), both of British technology.
Within the history of nuclear energy there was also…
The pressurized water nuclear reactor is the type of nuclear reactor more used worldwide in the nuclear power plants of generation of electricity. At present, there are more than 230 nuclear reactors in the world made with the pressurized water system. Also known by its abbreviations PW. Its main feature is the use of water under high pressure in the primary circuit to prevent it from boiling.
Within the naval engineering the pressurized water nuclear reactor (PWR) is widely used. In fact, this model was originally designed to be used on a nuclear submarine.
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…
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…
