摘要： PROBLEM TO BE SOLVED: To enable the continuous operation control of internal pumps according to a required core flow rate without continuous service at a speed which spurs the vibration of the internal pumps, enlarge the range of the core flow rate which enables continuous operation by making it possible to swiftly passing through a resonance domain of a motor casing and shorten the time for realizing plant startup conditions.
SOLUTION: In this method for controlling the core flow rate in a reactor, the internal pumps which can operate at variable speeds are driven to control the core flow rate based on reactor operation request. The core flow rate in the reactor is controlled through the continuous operation of all the internal pumps in a speed domain where the vibration of the pumps is small by driving each pump or each group of an arbitrary number of pumps when the speed of the internal pumps reaches a domain which corresponds to the resonance domain and where they cannot rotate continuously, with velocity differentials which make it possible to evade the resonance domain of the internal pumps in a state of maintaining the whole core flow rate.
