Measurement system for measuring neutron flux in strong radiation and high temperature conditions

The invention relates to a measurement system for measuring a neutron flux in strong radiation and high temperature conditions and belongs to the technical field of nuclear reactor engineering. The measurement system mainly consists of a thermal neutron sensitive detector, a fast neutron sensitive detector, a thermal neutron absorber, two amplifiers, a data acquisition module and a neutron energy spectrum analysis module, wherein the thermal neutron absorber is wrapped around an outer surface of the fast neutron sensitive detector, signals detected by the thermal neutron sensitive detector and the fast neutron sensitive detector are respectively output to the two amplifiers, signals received by the amplifiers are processed and output, signals output by the amplifiers are subjected to digital processing operation via the data acquisition module, digitized signals are output by the data acquisition module, the neutron energy spectrum analysis module is used for subjecting received digitized signals to neutron energy spectrum analysis, neutron energy spectrum data can be obtained, and the neutron flux can be calculated based on the neutron energy spectrum data. The measurement system disclosed in the invention is advantaged by light weight, easy-to-install property, strong mobility, small measurement error and the like.
