Abstract

PURPOSE: To facilitate making sure the operating condition of a solenoid operated valve by sensing the leak flux produced at the energizing time of the solenoid and thereby lighting up a lamp etc.
CONSTITUTION: When a nuclear furnace manual control device 1 emits control rod inserting direction control solenoid-operated-valve drive signals 11, 12, inserting direction control valve solenoids 3, 4 are energized and solenoid operated valves 7, 8 are driven. At this time, sensor parts 15, 16 sense the leak flux produced when the solenoids 3, 4 are energized and signals therefrom are sent to amplifiers 19, 20 and further to converter parts 27, 28 to be converted into the ON signal which shall light up lamps of LEDs etc. in the display parts 31, 32. When the abovementioned drive signals 11, 12 have disappeared the display parts 31, 32 will go out. The drawoff direction control valve solenoid 5 and settle direction control valve solenoid 6 shall also go through the same procedure with sensor parts 17, 18, amplfiers 21, 22, converts 29, 30 and display parts 33, 34.
