표준형원전 2차측 열출력 감소인자에 대한 연구

Abstract

This study describes the turbine steam cycle that applied the Rankine cycle. It also reviews the factor that caused the unplaned efficiency reduction of the secondary thermal power in KSNP plant. Although there are many reduction factor, this study reviews the four important reduction factor. Those are the Steam Generator Tube Plugging, the Feedwater Flow Depletion, Uncontrolled Level Fault of Heaters and Vacuum Depletion of Condenser. Throughout reviewing the unplaned efficiency reduction factor, the study reviews to have effects on the turbine steam cycle and tries to find the applicable solution against the unplaned efficiency reduction factor in KSNP plant. This study also describes the applied solution in KSNP plant and the applicable solution in immediate future
