This is Describes about the Operational Aspects of Combined Cycle Power Plant, Main concentration is on Performance Analysis and Thermodynamic aspects of all the sub systems. The effective heat utilization and accounting of Exergy in the work consumable devices and work extractable. The improvement aspects of various power plants based on combined cycle has been discussed. This book contains the information regarding the working, improving the efficiency of a combined cycle power plant through exergy analysis. In the combined cycle power plants, natural gas is used as major fuel. These plants can achieve higher efficiency in converting fuel to electricity which makes it possible for relatively high priced fuel like natural gas to be competitive for intermediate or base loads

In the advancing world of today, the demand for the clean and reliable electricity is constantly increasing.The technological developments in operating nuclear power plants with higher efficiency and more safety will be possible with gas cooled reactors. Handling gas cooled reactors under critical conditions is more effective than conventional nuclear reactors. The capacity addition is only possible with advanced nuclear reactors.This book will demonstrate various aspects of Nuclear power plant design with gas cooled reactors
