摘要： An ex-core nuclear instrumentation system in which the width of measurable neutron detector current can be accurately widened is obtained. In order to output the condition of neutron flux in operation by performing arithmetic processing of a current value measured by a neutron detector by using a detector signal processing circuit, the detector signal processing circuit includes a current/voltage conversion unit which converts the current value converted by the neutron detector into a voltage value corresponding to the current value; and a variable gain amplification unit which has an operational amplifier having a resistance circuit for corresponding to current levels, the resistance circuit being capable of selecting a gain, and a D/A converter that adjusts the gain, and amplifies the voltage value converted by the current/voltage conversion unit.

摘要： A waveform analyzing section analyzes the waveform of a detector signal pulse. A calculation section calculates a count rate from the addition-subtraction accumulated value of an up-down counter, and detects noise intrusion, based on the output from the waveform analyzing section. When noise intrusion has been detected, the addition-subtraction accumulated value for the present calculation cycle is replaced with the value for the previous calculation cycle. When the noise intrusion has stopped, the addition-subtraction accumulated value of the up-down counter is set at the value for a calculation cycle just before the noise intrusion, by an accumulated value setting circuit.
