PROBLEM TO BE SOLVED: To provide a coupling capacitor charge correction control circuit for eliminating a variable resistor for adjusting a transistor element characteristic and improving reliability in a neutron flux measurement system. SOLUTION: The coupling capacitor charge correction control circuit, corrects charge accumulated in a coupling capacitor for transmitting a pulse signal in a neutron flux measurement system for measuring neutrons by counting signal pulses generated from a neutron flux detector, and is provided with charge and discharge circuit means D1 to D3, R1, R6 for charging and discharging the coupling capacitor and a comparator IC comprising a single chip semiconductor IC, comparing a potential of the coupling capacitor with a predetermined potential, determining which of positive and negative polarities of the coupling capacitor the charge is accumulated based on a passage of the positive signal pulses from the neutron flux detector and controlling charge and discharge of the charge and discharge circuit means.
