Abstract
本发明涉及一种核电机组一回路稳压器控制方法，应用于核电机组的上行过程和下行过程，核电机组包括RCV系统，RCV系统包括下泄回路、容控箱和加氢站单元、上充泵单元、轴封单元以及上充回路；上充泵单元包括至少两台上充泵，轴封单元上设有电动调节阀，至少两台上充泵分别与电动调节阀连接；核电机组一回路稳压器控制方法包括在核电机组的下行过程中的控制步骤：控制至少两台上充泵同时运行；控制电动调节阀的开度；控制一回路在预设温度范围内连续冷却，同时，至少两台上充泵向稳压器注流以灭汽腔。本发明通过提高RCV系统的上充下泄能力，以实现一回路建汽腔与一回路升温同步进行，以及一回路灭汽腔与一回路降温同步进行。
