The document provides an overview of nuclear power plants, including their definition, operating principles, key components, advantages, and disadvantages. It discusses how nuclear power plants work by using nuclear fission to heat water and create steam to power turbines that generate electricity. The major components include a heat source (nuclear reactor), turbine, generator, condenser, pumps, cooling water, and cooling towers. Advantages include no carbon emissions or air pollution, while disadvantages include expensive nuclear waste disposal and decommissioning costs as well as potential radiation risks from accidents.

4. Nuclear power plant

5. Definition
NUCLEAR POWER PLANT IS A THERMAL
POWER STATION IN WHICH THE HEAT
SOURCE IS A NUCLEAR REACTOR.

6. Operating principle of nuclear power
plant
A NUCLEAR POWER PLANT IS A FACILITY AT WHICH ENERGY
RELEASED BY THE FISSION OF ATOMS IS CONVERTED TO
ELECTRICAL ENERGY UNDER STRICTLY REGULATED
OPERATING CONDITIONS.

7. Component of power plant
# HEAT SOURCE
#TURBINE/GENERATOR
#CONDENSER
#PUMP
#COLLING WATER
#COOLING TOWER

8. TURBINE/GENERATOR: USES THE ENERGY OF THE STEAM TO
TURN A TURBINE/GENERATOR THAT PRODUCES ELECTRICITY.
CONDENSER: CONDENSES THE STEAM BACK TO WATER SO
THAT IT CAN BE RETURNED TO THE HEAT SOURCE TO BE
HEATED AGAIN.
PUMP: PROVIDES THE FORCE TO CIRCULATE THE WATER
THROUGH THE SYSTEM.
Heat source: Provides heat to generate steam

9. Cooling water
THIS COOL SURFACE IS PROVIDED BY
COOLING WATER PUMPED FROM A
NEARBY WATER SUPPLY SUCH AS A
RIVER, LAKE OR OCEAN.

10. Cooling Towers
 The water used to cool the condenser is slightly warmer
after use.
 cooling tower is sometimes used to prevent a harmful
temperature rise in the water supply.
 A cooling tower is a large heat exchanger. This heat is
carried up the stack and is visible as water vapor.
 Cooling towers are used at many large nuclear as well
as non-nuclear power plants.

11. ADVANTAGES
 Geographical limitations - nuclear power plants don't require a lot of
space.
 Nuclear power stations do not contribute to carbon emissions.
Therefore does not contribute to global warming.
 Nuclear power stations do not produce smoke particles to pollute
the atmosphere or emit gases that contribute to acid rain
 Nuclear power is reliable. It does not depend on the weather.

12. DISADVANTAGES
 Disposal of nuclear waste is very expensive. As it is radioactive it has
to be disposed of in such a way as it will not pollute the environ
 Decommissioning of nuclear power stations is expensive and takes a
long time.
 Nuclear accidents can spread 'radiation producing particles' over a
wide area, This radiation harms the cells of the body which can
make humans sick or even cause death.

13. Comparison
Nuclear Power plant
 Do not required large space.
 Fuel is expensive so Requires
larger capital cost .
 Do not depend on weather.
 Limited to water surface
 Setup is very costly and
decommission is almost impossible.
 Produce electrical power
continuously .
Wind Turbine
 Required large space.
 Wind is free so it’s capital cost is
not so high as compeered to
Nuclear power plant.
 Highly climate dependent.
 Limited to windy areas.
 Easy to setup easy to move.
 Power generation depend on
wind
