Description
Letdown H / E outlet pressure low alarm occurrence has been frequently occur by fluctuation phenomenon of the flow rate and back pressure of Chemical and Volume Control System (CVCS) in nuclear power plants with increasing operating time. Due to this problem it was caused a problem that the chemical and volume control system letdown flow rate control is unstable. This study was performed to analysis the operability of control valve to solve the problems caused by letdown flow rate control instability of chemical volume control system in nuclear power plant. As a results completion of the corrections and diagnostic tests, it shows the control performance of the valve is sufficient to control the letdown flow. Table II shown that the control valve error rate after corrections. We confirmed that the control of the control valve is operating normally
