2. What is Nuclear Power Plant?
 A power plant in which nuclear energy is converted into heat for use
in producing steam for turbines, which in turn drive generators that
produce electric power. Also known as atomic or nuclear power
plant.
 By generating enough heat to turn water to steam, a nuclear power
plant is a facility that can produce a huge amount of electricity.
 Fission:
U235+0n1 Ba 141+Kr92+2.50n1+200 MeV energy.
Fusion:
H-2 + H-3  He-4 + n + energy

3. Type of Nuclear Power Plant:
The Pressurized Water
Reactor (PWR)
Boiling Water
Reactor (BWR)

4.  Working principle :
 A nuclear power plant works in a similar way as a thermal
power plant. The difference between the two is in the fuel they
use to heat the water in the boiler(steam generator).
 Inside a nuclear power station, energy is released by nuclear
fission in the core of the reactor.
 1 kg of Uranium U235 can produce as much energy as the
burning of 4500 tons of high grade variety of coal or 2000
tons of oil.

10. Top 10 Nuclear Generating Countries

11. • Sudden cooling, decreased sunlight, less rainfall shortens growing
seasons; reduces crop yields
• Stratospheric zone depletion damages crops sensitive to UV-B
• Disruption of petroleum supplies affects use of farm machinery and
fertilizer and pesticide production
• Radioactive and toxic contamination takes farmland out of production
• Collapse of distribution system
The Impact on Agriculture

12.  Advantages of Nuclear power plant:
 Space required is less when compared with other power plants.
 Nuclear power plant is the only source which can meet the
increasing demand of electricity
at a reasonable cost.
 A nuclear power plant uses much
less fuel than a fossil-fuel plant.
1 metric ton of uranium fuel = 3
million metric tons of coal = 12
million barrels of oil.

13. Disadvantages of Nuclear power plant:
 Radioactive wastes must be disposed carefully, otherwise it
will adversely affect the health of workers and the environment
as a whole.
 Maintenance cost
of the plant is high.

14. The countries of the world are each planning their own course
of nuclear plant development or decline
Nuclear power is competitive with natural gas
It is non-polluting
It does not contribute to global warming
Obtaining the fuel only takes 5% of the energy output
Plant licenses have been extended from 20 years to an
additional 20 years
Nuclear Plant Future

15.  Newer designs are being sought to make them more
economical and safer
 Preapproval of a few designs will hasten development
 Disposal of high level radioactive waste still being
studied, but scientists believe deep burial would work
 Because they are have large electrical output, their cost
at $2 billion is hard to obtain and guarantee with banks
 Replacing plants may be cheaper using the same sites
and containment vessels

16.  At present, as a developing country like Bangladesh it is not possible to
supply sufficient electricity without nuclear energy. So, we need to
produce enough energy or electricity by building nuclear power plant as
soon as possible. For this purpose…………..
Bangladesh has taken plan to build nuclear power plant by
2016 as vision of 2021. Bangladesh said, it will produce
1000 megawatt power with technological support from
Russia. ( Ref: www.bdnews24.com)
