Zusammenfassung:	PURPOSE:To obtain the data of important plant events visually by displaying the plant events which are displayed as trend graphs as icons. CONSTITUTION:On the screen of a CRT 29 of a plant monitoring apparatus 22, the water level of a vapor generator (SG), main vapor pressure (b) and trend graphs 1, 8 and 5 of the flow rates of auxiliary water supply are displayed as process quantities. The associated plant events of (low compressor control pressure) reserve-heater-in 2, (compressor) water-level-deviation-large 3 and (atomic reactor) trip 6 are displayed. Namely, when the plant events and the important plant events are detected during the operation of the plant, the plant events are displayed with icons 2, 3 and 6. The data of each part of the plant 21 are inputted into an input interface 23 of the plant monitoring apparatus on-line and processed in an operating part 25 in accordance with the programs stored in a built-in memory 26 in an electronic computer 24. The processed data are displayed on the CRT 29 by the instructions from a keyboard 27 and a touch sensor 28.
