and is the second highest among the Country.

4. INTRODUCTION
With the world on a development ,
there is shortage of power in most places
while the demand seems to be in a never
ending . There are several answers to this
challenge such as the nuclear power plants,
but the conventional thermal power plants
also play an equally important role in this
power generation..
