The atomic / nuclear reactor is the site of a chain reaction involving a controlled fission reaction. A reactor is an efficient energy source. The
fission reaction of 1 gram of nuclides per day will generate energy of 1
MW (106 W), this is proportional to burning 2.6 tons of coal per day to
produce that much energy. The energy released in a
nuclear reactor arises as heat energy and can be taken by passing
liquids or gases for cooling, through the interior of the reactor.
The energy is then transferred out of the reactor by a secondary coolant that will convert the heating energy into steam energy which can be used to drive the turbine which will drive the dynamo / generator, so that electric energy will be obtained. Enrico Fermi was the first to successfully set up a nuclear reactor at a successful Chicago university in December 1942. As a fuel the reactor was uranium-235.

The power plant is a reactor that can generate electrical energy. The power plant is a commercial reactor that produces electrical energy for sale such as NPP (Nuclear Power Plant)
The research reactor is a reactor used for research in agriculture, animal husbandry, industry, medicine, science, and so on.
The nuclear reactor is an apparatus as a site for controlled nuclear fission chain reactions to generate nuclear energy, radioisotopes, or new nuclides.
Basic Atom / Nuclear Reactor
Information :
(1). The nuclear reactor fuel is the material that will cause a fission chain reaction to take place on its own, as a source of nuclear energy. The fission isotopes are uranium-235, uranium-233, plutonium-239. Uranium-235 is present in nature (by a ratio of 1: 40 in natural uranium), and the other must be artificially produced.
(2). The reactor terrace, in which there is a fuel element that wraps the fuel.
(3). Moderators are reactor components that serve to decrease the energy of rapid neutrons (+2 MeV) into normal reactor components (+ 0.02 - 0.04 eV) in order to react with nuclear fuel. In addition, the moderator also functions as a primary cooler. Requirements required for good moderating materials are able to remove most of the neutron's rapid energy in each collision and have little ability to absorb neutrons, and have a great ability to dissipate neutrons. The materials used as a moderator, among others:
(4). Setiap Each fission reaction produces more new neutrons (2-3 new neutrons), it is necessary to regulate the number of neutrons reacting with the fuel. The reactor component acting as a regulator of the number of neutrons reacting with the fuel is the control rod. In the reactor is known the multiplier factor (k), ie the ratio of the number of neutrons generated per cycle to the number of neutrons at the beginning of the cycle to:

(5). Shielding (shielding), serves as a radiation holder of the fission of the material so as not to spread to the environment.
(6). The heat transfer, serves to remove heat from the primary cooler to the secondary coolant with a heat transfer pump.
(7). Secondary coolant, can also serve as a steam generator (steam generator) which can then be used to power an electric generator.
The reaction of the atomic nucleus can take place very quickly and generated enormous energy. Of the nuclear reaction energy humans can utilize for human welfare but some also utilize as a tool of mass murder, for example atomic bombs and hydrogen bombs as weapons of war in this modern age. In terms of human welfare utilize nuclear reation using atomic / nuclear reactor for power plant and others.
The energy is then transferred out of the reactor by a secondary coolant that will convert the heating energy into steam energy which can be used to drive the turbine which will drive the dynamo / generator, so that electric energy will be obtained.

Types of Atom / Nuclear Reactors
According to its usefulness, nuclear reactors can be divided into three.1. Isotope Production Reactor
Isotope production reactor is a reactor that produces radioisotopes widely used in the fields of nuclear, medicine, biology, industry, and pharmaceuticals.2. Power Reactor / Power
The power plant is a reactor that can generate electrical energy. The power plant is a commercial reactor that produces electrical energy for sale such as NPP (Nuclear Power Plant)
3. Research Reactor
The research reactor is a reactor used for research in agriculture, animal husbandry, industry, medicine, science, and so on.
The nuclear reactor is an apparatus as a site for controlled nuclear fission chain reactions to generate nuclear energy, radioisotopes, or new nuclides.

- K = 1, reactor operation in critical condition,
- K> 1, reactor operation in a super critical state,
- K <1, reactor operation in subcritical state.
