What? How is it produced?
In terms of nuclear energy, it is usually understood that the energy resulting from the fission (nucleus division) is the end result.
(Another nuclear power generation path is fusion, core fusion, but fusion, years
Despite the struggle, practically it has not been brought to a promising point.) Some isotopes are neutrons
split with kinetic energies that they gain from cleavage products
the sixth of the resulting energy) try to move away from the scene. This moves within the fold of the fold
means (study to do); As expected the environment gets very hot. Nuclear energy ultimately heat
as an energy source.
The nuclear reactor is designed to allow continuous and regular production of this energy
a machine. For continuous and regular production, two things must first be achieved: (1) the fission
the reaction is maintained in an individual (controlled manner) and (2)
withdraw from media.
Some isotopes are "fissile", ie they are swallowed by a slow (low-energy, even non-energized) neutron
they are most likely divisions. Fisil isotopes play a major role in nuclear energy production. Each
the fission result is 2 or 3 neutrons. (If the fisil isotope ratio in the environment is lower than that of each new neutron
if it is at a level that would lead to a re-fission, the number of f
it grows and becomes an uncontrolled energy output. Uncontrolled fission chain reaction atom
It forms the basis of the bomb.)
The nuclear reactor is designed to provide a one-to-one realization of the fission reaction;
for which only one out of 2 or 3 neutrals, each of which has a finite end result,
(reactor core) is created. Excess neutrons without fission
swallowed or escaped from the system. Thus, the unit
the number is kept under control (constant) and continuous heat production can be realized.
As a result of the fission,
Another important function of the nuclear reactor is. Contains fisil isotope in a predetermined area
the nuclear fuel material is placed in a suitable geometry and the generated heat is transferred to a cooler
(usually water). In the electricity generation of heat
use is provided by steam (or rarely gas) turbines. Steam (or hot gas) and electricity
production is not specific to nuclear energy, how is it in a typical coal or natural gas power plant

it is almost the same in nuclear. Nuclear reactor in the electricity generation system
has undertaken; ie it is produced by fission rather than by burning heat, coal or natural gas,
This is the difference.
In summary; nuclear reactor, a nuclear reaction (fission) controlled
and the continuous and regular production of the heat released during this process; safe,
environmentally and reliably.
This machine has been used for 40-50 years, as of June-June 433 in 29 countries,
operated to produce electricity; 63 of them are under construction. Total board on earth
nuclear power is at 370000 MWe (megawatts-electricity) and world electricity
meets one of your needs. [World Nuclear Association, 2012]
Uses outside of electricity production
Nuclear reactor, besides electricity production which is the most important usage field, is a direct heat source
can also be used as; the need for various industries, especially chemistry (and engineering)
(seawater, fresh water, coal, coal gas,
it becomes very important in areas requiring intense heat such as hydrogen production). Nuclear energy, health
for diagnosis and treatment in the sector; many important isotopes in industry, agriculture and animal husbandry
for production; from heart valves to energy generators for satellites and space vehicles
used in the festival. In addition, the nuclear reactor, submarines, aircraft
It is particularly preferred on ships (all submarines of the US are nuclear).
