Abstract

PURPOSE:To enable a reliable notification of a trouble to an operator by discriminating a lighting condition of a trouble alarm indication window, by a method wherein, in an operation control of a nuclear power plant, alarm-sounding and flickering for an indication window are separately suspended at a time when a trouble occurs. CONSTITUTION:Through the occurrence of a trouble element 3 at an optional timing, a trouble indicating window 12, connected to a corresponding detectr 4, flickers at a high speed, and a trouble occurrence alarm sounds. With an alarm stopping button 39 then depressed, the trouble occurrence alarm stops sounding, and the window 12 continues to flicker at a high speed. Through the occurrence of a succeeding trouble element 3, the window 12 corresponding to a corresponding detector 4 flickers at a high speed, and the trouble occurrence alarm sounds again. In this case, to facilitate indentification of a following trouble from a proceeding trouble, the flickering period of the window 12 is inverted in phase. With the button 39 operated again, the alarm stops sounding, and the window 12 is changed into a high-speed flicker at the same phase. Then, with a button 34 operated, each indication window 12 is changed into a continuous lighting.
