Document Type and Number:
Japanese Patent JP7291545
Kind Code:
B2
Abstract:
To provide a furnace physical inspection device etc., capable of properly performing furnace physical inspection while avoiding a risk of generation of a plant trip.SOLUTION: In a furnace physical inspection device which uses plant data to execute furnace physical inspection, the plant data is an IR digital signal output from a neutron detector, a processing part executes a data acquisition stage S1 for acquiring the IR digital signal from a digital communication bus, and an arithmetic processing stage S2 for using the acquired IR digital signal to perform arithmetic processing on behavior of a nuclear reactor. At the arithmetic processing stage S2, the IR digital signal is input, an analysis code for analyzing behavior of the nuclear reactor is used, and also includes a correction coefficient for correcting response characteristics of a neutron detector, and the acquired IR digital signal is corrected with the correction coefficient, thereby performing arithmetic processing on the behavior of the nuclear reactor from the corrected IR digital signal using the analysis code.SELECTED DRAWING: Figure 2
