What is power plant ?

}A complex of structures, machinery, and associated equipment for generating electric energy from another source of energy, such as nuclear reactions or a hydroelectric dam is called power plant and also called powerhouse, power station.

What is the purpose of power plant ?

}Energy is the basic and major requirement now a days. The main purpose of power plant is the production of electrical energy using different energy sources to full fill the present and incoming demands of energy.

Types of power plants.

}Nuclear power plant

}Wind power plant

}Hydraulic power plant

}Coal power plant

}Geo thermal power plant


}Nuclear power is the use of sustained nuclear fission to generate heat and do useful work. Nuclear Electric Plants, Nuclear Ships and Submarines use controlled nuclear energy to heat water and produce steam, while in space, nuclear energy decays naturally in a radioisotope thermoelectric generator. Scientists are experimenting with fusion energy for future generation, but these experiments do not currently generate useful energy.

Advantages of nuclear power plant

}Nuclear power generation does emit relatively low amounts of carbon dioxide (CO2). The emissions of green house gases and therefore the contribution of nuclear power plants to global warming is therefore relatively little.

}This technology is readily available, it does not have to be developed first.

}It is possible to generate a high amount of electrical energy in one single plant.


}Nuclear power plant use the basic purpose that its uses the radiation energy emitted by radioactive elements (usually uranium-235 or plutonium-239) to convert water into steam and that steam is used to rotate turbine that is coupled with the generator to produce the electricity.

Fusion in nuclear power plan ?

}Fusion power advocates commonly propose the use of deuterium, or tritium, both isotopes of hydrogen, as fuel and in many current designs also lithium and boron. Assuming a fusion energy output equal to the current global output and that this does not increase in the future, then the known current lithium reserves would last 3000 years, lithium from sea water would last 60 million years, and a more complicated fusion process using only deuterium from sea water would have fuel for 150 billion years.[ Although this process has yet to be realized, many experts believe fusion to be a promising future energy source due to the short lived radioactivity of the produced waste, its low carbon emissions, and its prospective power output.

Disadvantages of nuclear power plant

1.The problem of radioactive waste is still an unsolved one. The waste from nuclear energy is extremely dangerous and it has to be carefully looked after for several thousand years (10’000 years according to United States Environmental Protection Agency standards).

2.High risks: Despite a generally high security standard, accidents can still happen. It is technically impossible to build a plant with 100% security. A small probability of failure will always last. The consequences of an accident would be absolutely devastating both for human being as for the nature . The more nuclear power plants (and nuclear waste storage shelters) are built, the higher is the probability of a disastrous failure somewhere in the world.

3.Nuclear power plants as well as nuclear waste could be preferred targets for terrorist attacks. No atomic energy plant in the world could withstand an attack similar to 9/11 in Yew York. Such a terrorist act would have catastrophic effects for the whole world.
