what is nuclear energy?
The energy stored in the nucleus of an atom.
Atomic energy: the energy released by a nuclear reaction
How nuclear energy is produced
Two reactions from which nuclear energy is produced in nuclear reactor:-
1. nuclear fission
2.nuclear fusion
What is nuclear fission?
Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts and producing free neutrons and photons (in the form of gamma rays) and nuclear energy.
Mainly U235, 239Pu are used in nuclear fission
Nuclear fusion
In nuclear fusion reaction two light atomic nuclei fuse together to form a heavier nucleus and release energy.
And the power generated by nuclear fusion reactions refers to nuclear power.
Nuclear energy in india
India has a flourishing and largely indigenous nuclear power program and expects to have 20,000 MWe nuclear capacity on line by 2020. It aims to supply 25% of electricity from nuclear power by 2050.
Because India is outside the Nuclear Non-Proliferation Treaty due to its weapons program, it has been for 34 years largely excluded from trade in nuclear plant or materials, which has hampered its development of civil nuclear energy until 2009.
Due to these trade bans and lack of indigenous uranium, India has uniquely been developing a nuclear fuel cycle to exploit its reserves of thorium.
From 2009, foreign technology and fuel are expected to boost India's nuclear power plans considerably.
India has a vision of becoming a world leader in nuclear technology due to its expertise in fast reactors and thorium fuel cycle.
