The document describes hydel and nuclear power plants. For hydel power plants, dams and reservoirs are constructed on large rivers to store water at height, which is then sent through penstocks and water turbines to generate electricity. Nuclear power plants use nuclear fission reactions in reactors to produce heat and generate steam to power turbines connected to generators. Both have advantages like being reliable and efficient or occupying less space, but also have disadvantages such as high construction costs or producing harmful radioactive waste.

3. HYDROELECTRIC POWER PLANT
Dam and Reservoir: constructed on a large river
in hilly areas for water storage at height.
Penstock: a huge steel pipe which carries water
from the reservoir to the turbine
Control Gate: water released into the penstock is
controlled by a control gate.
Water Turbine: Kinetic energy of the water drives
the water turbine and the generator gets driven.
Surge Tank: reduces pressure swings in the
penstock.

4. ADVANTAGES:
• Reliable and efficient
• Economical
• Clean and flexible
DISADVANTAGES:
• Construction cost is high
• Safety concerns
• Displacement of people

7. NUCLEAR POWER PLANT
Nuclear energy is converted to electrical energy
Nuclear Reactor: Nuclear fission reaction produces
heat
Heat is taken by coolant circulating in reactor
Heat Exchanger: hot coolant flows through the tubes of
heat exchanger
Heat is transferred to feed water and steam is
produced
Steam turbine: steam rotates the turbine which is
connected to generator
Later steam leaves the turbine and flows to condenser

9. ADVANTAGES:
• Occupies less space
• Power production is high
• Water consumption is less
DISADVANTAGES:
• Initial cost is high
• Radioactive wastes are harmful
• Maintenance cost is high
