Zusammenfassung:	PURPOSE:To improve both the safety and reliability of a plant by delivering previously the operating guidance for future operations to an operator based on the results given from a device that estimates a plant state quantity. CONSTITUTION:A data base 10 of an atomic power plant is formed with the plant state quantity signal supplied from a process input device. In such a case that a scrum occurs, a present value processor 121 informs a plant state estimating device 122 of the breakage scale if the occurrence is caused by a loss of a cooling accident or sticking in an open state of a S/R valve. Otherwise the device 122 is started for analysis of the fault phenomenon performed on the basis of the results of the base 10 and the processor 121. Then the state quantity of a primary parameter is estimated for the state quantity of the power plant. The result of analysis is delivered to a color CRT display device 14 via a display drive circuit 13.
