摘要： PURPOSE:To enable highly accurate monitoring and forecasting by using a three- dimensional core performance calculation model to correct a quantity of state of a core such as core output, core flow rate and three-dimensional output distribution based on an actual operation data. CONSTITUTION:When an operation is started according to an operation program and a demand for monitoring the condition of a core is inputted from an interactive section 19, a correction method selecting section 12 picks up and compares a quantity of state of a core such as current furnace output, core flow rate and control rod pattern with data preserved at a preliminary calculated value preserving section 11 to select a preliminary calculated value at an operating point the nearest the current quantity of state of core and the preliminary calculated value selected is compared with the current quantity of state of core. When the furnace output and core flow rate are deviated slightly, a first output distribution correcting section 13 is selected to correct a three-dimensional output distribution in preliminary calculation. When the control rod pattern is also deviated due to an action during the course of operation, a second output distribution correcting section 14 is selected. If the core output and core flow rate are deviated significantly, the correction is done by selecting a three- dimensional output distribution correcting section 15.
