The energy stored in the nucleus of
Atomic energy: the energy released
by a nuclear reaction
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
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.
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
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
Fission reaction is a chain reaction where
fusion is not a chain reaction
In Fission reaction energy produced is high as
compared to fusion reaction.
Fusion occurs natrually in stars and is the
power source of the Sun where fission reaction
is not a natural.
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.
The problem of radioactive waste is still an unsolved
one. The waste from nuclear energy is extremely
High risks: Despite a generally high security standard,
accidents can still happen. It is technically impossible
to build a plant with 100% security.
The energy source for nuclear energy is Uranium.
Uranium is a scarce resource
The time frame needed for formalities, planning and
building of a new nuclear power generation plant is in
the range of 20 to 30 years in the western democracies.
In other words: It is an illusion to build new nuclear
power plants in a short time.
