摘要： PURPOSE: To improve position control by preventing the overshoot and vibration of an actuator by controlling a water supply flow valve, with which the level of water in a nuclear reactor pressure vessel is controlled, based on a prescribed actuator rod speed schedule. CONSTITUTION: The flow of water supply to a nuclear reactor pressure vessel 12 is controlled through an actuator rod 48 coupled to a water supply control valve 28. Therefore, the rotating speed of a motor 42 is controlled by connecting an electric controller 56 to the motor 42 and a sensor 60 and as a result, the position of the actuator rod 48 is controlled in response to a position request signal Pd. The controller 56 is provided with the predetermined actuator rod speed schedule. Thus, motor speed Sd is controlled in response to a position error signal and the position of the rod 48 is continuously controlled. Concerning this schedule, a zero speed signal is supplied up to the dead zone value of the error signal, a modulation speed signal is supplied up to a modulated value higher than this dead zone value and further, an excessive value speed signal is supplied corresponding to the error signal higher than the larger excessive value respectively.

摘要： PURPOSE: To obtain various selectable automatic suppression functions capable of suppressing thermal-hydraulic instability of a boiling water reactor and stabilizing the reactivity of a core. CONSTITUTION: This nuclear reactor is constructed of a pressure vessel 10 holding a core 12 and steam separating-drying equipment 14, a recirculation pump 16 extracting a coolant from a downcomer area through a recirculation pipeline 20 and sending it into a lower plenum 22 through a recirculation pipeline 24 and a flow control valve 25, a pressure relief valve 33 protecting a main steam pipeline from an excessive pressure, a feed water pump 36, a controller 40 operating in response to various inputs so as to regulate operations of the pumps 16 and 36 and a turbine control valve 28 in accordance with an operating state and on a real-time basis, a local output region detector assembly 42, a vibratory output detecting device 44 and a reactivity regulator 52 receiving automatic suppression function(ASF) signals. A dome internal pressure, a core flow rate or coolant enthalpy is changed in a random manner by this construction and thereby the nuclear reactor is stabilized.
