摘要： A detector path insertion verification system for use with flux mapping of a pressurized water nuclear reactor uses a transfer insertion switch (54) at the input of each multiple-path selector (30) to detect insertion of a detector into the multiple-path selector (30). No insertion switches are used at the output of the multiple-path selectors; instead software is used to verify the position of the multiple-path selectors. The sensed actual position of each multiple-path selector is monitored as the multiple-path selector is rotated to verify that the sensed actual position passes through the expected sequence of positions in an expected amount of time. The multiple-path selectors are rotated until a sensed actual position is equal to a desired position and rotation is stopped. After the passage of a short period of time, the actual and desired positions are again compared and if equal, insertion is begun. When the transfer insertion switch (30) detects insertion of the detector into the multiple-path selector, the actual and desired positions are again checked and insertion of the detector is continued only if the actual and desired positions are still equal.

摘要： A beta ray flux measuring device 30 in an activated member in-core instrumentation system 2 for pressurized water reactors 10. The device includes collector rings 110 positioned about an axis 80 in the reactor's pressure boundary 120. Activated members 85 such as hydroballs 90, 165 are positioned within respective ones of the collector rings 110. A response characteristic such as the current from or charge on a collector ring 110 indicates the beta ray flux from the corresponding hydroball 90, 165 and is therefore a measure of the relative nuclear power level in the region of the reactor core 20 corresponding to the specific exposed hydroball 90, 165 within the collector ring 110.

摘要： A detector signal processing circuit comprises a current/voltage converting unit (21) which converts the current value, which is converted by a neutron detector (3), to a voltage value which corresponds to the current value; a variable gain amplifying unit (22) which includes an operating amplifier, in which a D/A converter is added, and amplifies the voltage value which is converted by the current/voltage converting unit (21); a regulation control means (26 to 28) which regulates a gain of the D/A converter; and a comparator (29) which automatically compares an output voltage, which is amplified by the variable gain amplifying unit (22), in accordance with a reference value which is previously set, so as to output the output voltage to the regulation control means (26 to 28).

摘要： A detector signal-processing circuit (8) comprises the following: a current/voltage conversion part (21) that converts the current value of a neutron detector (3) to a voltage value; a variable gain amplification part (22) that performs amplification by a first-step variable gain using a D/A converter (53); a current level response-use resistance circuit (41) that selects the measurement range in accordance with the voltage value; temperature measurement units (82, 83, and 84) for measuring the temperature of the resistance circuit (41) for current level response; a temperature compensation part (81) for commanding gain compensation by the D/A converter (53) on the basis of the measured temperature; and a selective adjustment control part (26) for selective control of the measurement range and adjustment of the variable gain of the variable gain amplification part (22). Due to this configuration, neutron flux can be measured with high precision while maintaining a constant output precision, before and after switching of the measurement range.
