------------------------------------------------- IMPACT OF NUCLEAR POWER PLANT IN KUDANKULAM
What is Nuclear Power? Nuclear power, or Nuclear energy, is the use of exothermic nuclear processes, to generate useful heat & electricity. The term includes the following heat producing processes – nuclear fission, nuclear decay and nuclear fusion.

Uses
1. Nuclear power is a low carbon method of producing electricity & in 2011 nuclear power provided 10% of the world's electricity. 2. Many military and some civilian (such as some icebreaker) ships use nuclear marine propulsion, a form of nuclear propulsion. 3. A few space vehicles have been launched using full-fledged nuclear reactors: the Soviet RORSAT series and the American SNAP -10 A. 4. Both Fission and fusion appear promising for space propulsion applications, generating higher mission velocities with less reaction mass. (Due to the much higher energy density of nuclear reactions: some 7 orders of magnitude (10,000,000 times) more energetic than the chemical reactions which power the current generation of rockets). 5. International research is continuing into the use of nuclear fusion, and additional uses of process heat such as hydrogen production (in support of a hydrogen economy), desalinizing sea water, and for use in district heating systems.

What is Nuclear Reactor? A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction.
Nuclear reactors are used at nuclear power plants for generating electricity and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which runs through turbines Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are
