Nuclear fission works by splitting the atoms apart to produce
smaller atoms, and as a result energy is released. Nuclear fission
is used in nuclear power plants to generate electricity through
the splitting of the nuclei of uranium atoms. Heavy nuclei split
into two smaller parts in order to become more stable.
5. 1.Howto produceNuclearEnergy ?
How a NuclearReactorworks?
• 235U fissions by absorbing a neutron and producing 2 to 3
neutrons, which initiate on average one more fission to make
a controlled chain reaction.
• Normal water is used as a moderator to slow the neutrons.

NuclearFussion
• Fusion easiest for Deuteron (D) +
Tritium(T):
D(p,n) + T(p,nn) → 4He(pp,nn) + n
in a high temperature plasma.
• Replacement T created from Li
blanket around reactor
n + 6Li → 4He + T

NuclearFussion
• International ITER in 2012
for research for a decade,
costing $5 billion
• Current stalemate over
siting in France or Japan
• Followed by DEMO for a
functioning plant, taking
another 10 years.
• Design and completion of
a commercial plant not
until 2050.

Principalparts of a nuclear reactor:
• Core : Here the nuclear fission process takes place.
• Moderator : This reduces the speed of fast moving neutrons.
Most moderators are graphite, water or heavy water

10. • Heat is produced in the reactor due to nuclear fission and
there is a chain reaction.
• The heat generated in the reactor is carried away by the
coolant (water or heavy water) circulated through the core.
• Two separate water systems are used to avoid radioactive
substances to reach the turbine.
• Water in the core heated top 315°C but is not turned into
steam due to high pressure in the primary loop

Boiled Water Reactor(BWR)
• The water is circulated through the reactor where it converts
to water-steam mixture.
• The steam gets collected above the steam separator.
• This steam is expanded in the turbine which turns the turbine
shaft.

15. 4.Advantages-Disadvantages
Advantages
• Space required is less when compared with other power
plants.
• A nuclear power plant uses much less fuel than a fossil-fuel
plant.

17. 4.Advantages-Disadvantages
Disadvantages
• Nuclear waste (Spent nuclear fuel) is extremely hazardous and
must be stored safely for thousands of years.
• Uranium is ultimately a nonrenewable resource.
• Nuclear power plants are extremely costly to build.
• The slight possibility that nuclear power plants can have
catastrophic failures.

Worldwide in 2014 there are:
• 436 nuclear power plants operable.
• 71 nuclear power plants under construction.
• 174 nuclear power plants ordered or planned.
• 301 nuclear power plants proposed.

19. 5.NuclearPower;Presentand Future
• Plant licenses have been extended from 20 years to an
additional 20 years
• Newer designs are being sought to make them more
economical and safer
• Preapproval of a few designs will hasten development
